Many babies and young children with Down syndrome are late to reach the early motor
milestones such as grasping, rolling, sitting, standing and walking. There is wide
variability in progress, with some reaching these milestones as early as typically
developing infants and some being particularly slow in achieving them. Most parents
are advised that physiotherapy will help, but do we actually know the reasons for
this slower progress that will provide guidelines for effective therapy? Do we know
if physiotherapy actually makes any difference to progress and, if so, how? Is the
motor progress of children with Down syndrome just delayed (i.e. slower but otherwise
the same as in other children) or is it actually different â€“ due to physical differences
in their muscles, ligaments or central nervous systems?
Whatever the answers to these questions may be, we know from our own practical experience
and research that the majority of children with Down syndrome achieve all the basic
motor skills necessary for everyday living and personal independence. They may be
later to achieve them, and their movements may seem a little clumsy or less refined
as they carry out tasks, but they still have adequate skills for daily competence.
They may have more difficulty in becoming skilled in games and recreational activities
but many individuals do reach high levels of achievement when given the opportunity.
Research into the motor development and motor skills of children and adults with
Down syndrome is limited and, as we have studied the available information, we have
come to believe that some unhelpful myths keep being repeated as explanations, without
supporting evidence. One of those myths is hypotonia or 'poor muscle tone'. Almost
every article we have read has used hypotonia as an explanation, when in fact it
probably plays little part in determining children's motor progress. We will return
to this issue later.
In this article, we consider four questions.
- What do we know about motor development in typically developing
children and the factors that may influence rates of progress or levels of skills
achieved for different motor activities?
- What do we know about the pattern of motor development usually
seen in infants, children and teenagers with Down syndrome?
- What do we know about the effects of therapeutic interventions?
- Can we draw on these three sources of evidence to identify some
principles for effective intervention and activity programmes for individuals with
Down syndrome across the age range?
Before we can discuss motor skills, we need to recognise that the term covers a
wide range of activities and actions and we have divided them into three somewhat
arbitrary groups in order to more conveniently discuss therapies and interventions
What are motor skills?
The ability to move is essential to human development, and children develop a remarkable
range of motor skills from the first year of life through to adult life. Some are
essential to basic human development and others are specialised and optional. For
practical purposes, motor skills can be considered under two main headings:
- basic skills necessary for everyday life activities, and
- recreational or specialist skills which are optional and based on interests
Basic skills include sitting, walking, running, climbing stairs, picking
up objects, using cups, knives and forks, pouring drinks, dressing and managing
fastenings, holding and using pencils, pens, scissors and using keyboards.
Recreational skills include skipping, throwing, catching, hitting and kicking
balls, riding a tricycle or a bicycle, swimming, skiing and all sporting activities,
playing a musical instrument and playing computer games.
Basic skills are usually further divided into gross motor skills and fine
- Gross motor skills are those concerned with whole body movement including
sitting, walking, running and climbing stairs.
- Fine motor skills tend to be those requiring fine manipulation of fingers
and hands including picking up objects, using cups, knives and forks, pouring drinks,
dressing and managing fastenings, holding and using pencils, pens, scissors and
These divisions are somewhat arbitrary and do not imply the use of separate parts
of the motor system, as elements of gross motor control such as maintenance of balance
and body posture play a part in carrying out fine motor activities. However, they
provide a useful practical way of dividing the whole range of possible motor skills
and they link with the sources of therapy and teaching available to children and
parents. Physiotherapists tend to be expert in the development of basic gross motor
skills and occupational therapists tend to be experts in fine motor skills, although
their skills will often overlap. Recreational skills tend to be taught by teachers,
physical education experts, sports coaches and specialists such as music teachers.
Movement influences social and cognitive progress
While progress in basic gross and fine motor skills is important because the ability
to carry out the movements has direct and practical benefit on a child's daily living
and independence, motor progress is also important because these abilities also
influence social and cognitive development. The following list gives just a few
examples of these links;
- being able to reach and grasp allows a child to begin to explore the characteristics
of objects in his or her physical world;
- being able to sit increases the ability to use arms and hands for playing;
- being able to walk allows a child to carry toys and objects and to explore the world
more effectively than crawling;
- being able to move independently also increases opportunities for social interaction
and language learning. For example, once a child can move, they can go to see what
happens when the postman comes to the door or the telephone rings. They can follow
their carers around so that they are talked to and included in everyday activities.
1. What do we know about the development of motor skills
in typically developing children?
In this section we consider first what we know about how all human movements are
controlled and improved, and then what we know about the developmental progress
of motor skills in children. We have provided some detail for the reader because
a number of the explanations given for the motor delays of children with Down syndrome
can only be discussed if the reader has some knowledge of the mechanisms involved
The coordination of motor control
The mechanisms of normal motor control are complex and not yet fully understood.
Any movement requires the coordinated action of the brain, nerves, muscles and limbs
and, as a movement is carried out, there is fast continuous control and adjustment
occurring as the brain monitors the progress of the action. Feedback from the muscles
and limbs, from vision and from balance systems is an integral part of all movement
control as it is taking place. This is illustrated in Diagram 1.
Diagram 1 The co-ordination of motor control
The brain and spinal cord constitute the central nervous system (CNS). All of the
information processing necessary for producing the coordinated movement of skeletal
muscle takes place in the CNS.
The eyes obtain visual information about the environment and the body itself. This
information is integrated with other types of information as part of the feedback
system for muscular coordination.
The semi-circular canals near the inner ear (vestibular apparatus) provide information
about the position of the head relative to horizontal and vertical planes (indicating
upright, leaning or falling body positions) and acceleration (changes in speed).
They are therefore important in maintaining balance.
The nerves of the peripheral nervous system may be motor or sensory. Motor nerves
carry information from the central nervous system, and control muscle contraction
and relaxation. Sensory nerves carry feedback information from muscles, tendons
and other tissues to the CNS.
Muscle is a tissue which, using the glucose and oxygen provided by the circulating
blood, converts chemical energy into mechanical energy by contracting. Muscle contraction
produces the movements involved in all body activities. The two important types
of muscle are skeletal muscle and smooth muscle. Skeletal muscle moves the limbs,
trunk and other parts of the body which are involved in so-called voluntary movement.
It is controlled by nerves from the CNS.
Tendons are cable-like structures which connect muscles to the muscle attachments
Ligaments are similar to tendons but generally attach bones to each other.
The central nervous system
It is known that all 'voluntary' movement is controlled by impulses from nerves
that originate in the central nervous system, which consists of the brain and the
spinal cord. With the exception of some basic safety reflexes (spinal reflexes),
which may be mediated through the spinal cord, all coordinated movement sequences
are determined by the brain. Although there are parts of the brain that are mainly
concerned with the control of movement, such as the cerebellum and the motor and
pre-motor areas of the cortex, it is important to note that motor control is widely
distributed in the brain, with many other areas being involved.
The skeletal muscles are those which move the limbs, trunk, neck and other parts
of the body. They are sometimes called 'voluntary muscles' because they produce
the movements involved in activities such as walking, handling objects and participating
in sports. It is important to note that these movements, which involve a very large
number of brain activities as well as very many accurate muscle movements, are not
really under any form of conscious control at all. When we carry out these functions,
we are mainly conscious of the results we wish to achieve rather than the detailed
means by which we attain the outcome. For example, we think 'I will pick up my keys'
â€“ we do not think 'I need to move this muscle and then that one to direct my hand
to the keys'.
The peripheral nerves
Muscles have two basic forms of nerve supply:
- efferent nerves, which carry messages from the brain to the muscle, and
- afferent nerves, which carry information to the brain.
The efferent nerves activate systems which cause the muscle to contract with varying
degrees of strength and speed, depending upon the type of message and the type of
muscle fibres receiving the impulses. The impulses in the afferent nerves contain
feedback information about the movement and position of the muscles and limbs, which
the brain uses to ensure that the required movements are correctly carried out.
In order to maintain and control appropriate body posture, the brain obtains information
from number of sources:
- body position information from detectors in the muscles and ligaments (proprioception);
- visual information from the eyes (visual feedback);
- and information about the position of the body in relation to the horizontal and
vertical, as well as acceleration, from the semi-circular canals near the inner
ear (vestibular system).
All this information (feedback) is continuously processed in the brain and it enables
the brain to send appropriate instructions to the muscles to produce the highly
coordinated movement patterns required for normal function.
Ligaments and tendons
Tendons are cable-like structures which connect muscles to the muscle attachments
on bones. Ligaments are similar to tendons but attach bones to each other. It is
generally agreed that the ligaments in people with Down syndrome are more elastic
than in typically developing people. The effect of having ligaments which are more
stretchy than usual is that the joints are capable of a much greater range of movements
than is typical. It is likely that this effect has been confused with that of muscle
Change in performance over time
When children or adults begin to learn any new neuromuscular skill, such as walking,
drawing or swimming, they initially carry out the task in a clumsy, not very well
coordinated fashion. But, with sufficient practice, they will eventually perform
the task in a smoother and more efficient manner. The effects of practice on the
brain have been demonstrated with suitable brain imaging techniques.
During this learning period there may be some changes in the muscles involved, such
as some increase in strength, but virtually all of the changes related to the development
of the new skill take place in the brain. There is no evidence that factors such
as bone length, stretchy ligaments or altered muscle tone have any significant effect
on neuromuscular actions. Presumably this is because brain control systems compensate
for these factors during the learning process.
Since muscles 'do what they are told', and since the instructions to the muscles
all come from the brain, differences in the quality of movement such as slower or
less well coordinated movement, can be seen to have their origin in the brain and
where improvements in movement occur they are associated with changes in brain mechanisms.
It is thought that practice leads to learning and to the development of 'motor programmes'
or plans for particular movement sequences in the brain. These motor programmes
enable movement sequences to be performed more quickly and accurately over time.
As practice of the movement continues, the motor programmes become so well learned
that they are referred to as being automatised. It has been suggested that once
motor programmes are automatised, they make less demand on the information processing
capacities of the brain. The reader is reminded that the control of the majority
of basic movements is carried out at a subconscious level.
The effects of automatisation can be made clearer by considering a task in which
a series of complex movements are learned, such as when learning to drive a car.
In this situation the learner has to consciously control the series of movements
initially â€“ i.e. to think what to do next. However, over time, the series of actions
may become so well practised and automatised that virtually no conscious control
is needed to change gear or to steer the car. Now the driver can give full attention
to road conditions and safety, as the information processing demands of controlling
the car have been considerably reduced.
Information processing and decision making
In all movements, there is a significant information processing requirement as the
brain continuously processes feedback and sends control messages to the muscles
in order to carry out the activity successfully, but it is at a subconscious level.
The individual simply gets up and walks or picks up a cup without any conscious
consideration of the controls on the movements needed for the particular situation
â€“ any conscious mental activity is simply focused on the goal of the activity.
In addition, some motor tasks require conscious information processing and decision
making before carrying out the movement. The reaction time task used in research
is one example, as a conscious level of decision making is involved before initiating
the movement. The reaction time is the time taken between the signal to start a
movement and the movement itself. Here a person may be instructed to tap the right
button when the red light comes on or tap the left button when the green button
comes on. He or she has to identify which light is on and then initiate the correct
movement. A physical education lesson, in which the pupil has to follow instructions,
is another example involving conscious processing of information before or during
Processing demands and processing abilities may vary
The information processing and the decision making requirements of a motor task
may influence an individual's ability to perform the task or the speed with which
the task is carried out. Some individuals may take more time to process information
in the central nervous system and some may have more difficulty understanding task
requirements or following instructions.
The brain will give instructions to the muscles that compensate for the effects
of lax ligaments or muscle tone, or arm or finger length, when carrying out a movement.
The production and co-ordination of movement comes from the central nervous system.
Movements are controlled by the brain and practice leads to the establishment of
learned motor programmes, which increase the speed, accuracy and smoothness of movements.
The brain is focusing on the endpoint or goal of the activity and it controls the
muscles to move the limbs to achieve that goal. The brain will give instructions
to the muscles that compensate for the effects of lax ligaments or muscle tone,
or arm or finger length, when carrying out a movement.
Motor development from infancy
We have described the factors which influence all movements and in this section
we identify the way in which motor skills actually develop during infancy.
Motor skills develop in a predictable sequence
There are many studies which have demonstrated that basic gross and fine motor skills
usually develop in a specific order and the ages at which children sit, crawl, walk,
jump, run, drink from a cup, use a knife to cut or a pen to write letters, manage
buttons and zips have been documented. Specific gross and fine motor skills are
assessed on many developmental tests, and motor skills also influence the scores
of infants on some cognitive tests as they are expected to demonstrate their understanding
by picking up or manipulating objects or toys.
As all parents know, the age at which healthy, typically developing children reach
milestones can vary widely with some walking as early as 10 months and some as late
as 24 months. This variation is largely thought to be determined by genetic make-up,
but it is also affected by the opportunity to move and explore. For example, one
Chinese study demonstrated later walking in those children kept in beds or cots
for longer periods than usual because of living circumstances.
Later skills tend to be built on earlier ones
The early gross motor skills of sitting, standing and walking involve increasingly
successful control of body posture and balance and these will be needed for maintaining
body stability when bending to reach an object or later when writing and drawing,
and when developing sporting skills.
All motor skills improve over time and with practice
All children perform movements in a 'clumsy' or immature way at first and refine
their performance with practice.
This point has already been made, but it is worth emphasising. All children perform
movements in a 'clumsy' or immature way at first and refine their performance with
practice, often over many months or years. For example, for typical children, posture
control when walking continues to improve up to 7 or 8 years of age.
2. What do we know about the development of motor skills
in children and adults with Down syndrome?
Research into the development of motor skills in infants and children with Down
syndrome is limited at the present time[1,2,3] and it can be divided into two main types â€“ descriptive
studies and experimental studies.
Types of research
The studies of infants and children are mainly descriptive and there have been a
small number of experimental studies of children but most of the experimental work
has examined the skills of teenagers and adults. Descriptive studies usually document
the ages at which skills are attained. These may be basic gross and fine motor skills,
and sometimes recreational skills as well as component skills such as balance, or
eye-hand coordination. Experimental studies usually require participants to learn
a new motor action or to carry out actions at speed.
Limits of research
Unfortunately, the findings of many research studies in the area of motor skills
have to be interpreted with caution for several reasons.
Small numbers. Researchers have often studied very small numbers of children or
adults. For example, one widely quoted study reports findings based on 2 children
with Down syndrome in one age group and 4 in another.
Given the considerable variability of progress among children with Down syndrome,
it is impossible to judge how representative the performance of such small numbers
of children actually is, and therefore whether the findings can be generalised.
Comparison groups. Another weakness of many studies lies in the comparison groups
that they use. Many studies of both adults and children compare their motor skills
with typically developing individuals of the same chronological age, usually reporting
significant differences in performance, with those with Down syndrome having 'poorer'
skills. However, when the comparison group is matched on mental age, then there
is often no significant difference in the overall motor performance of the groups.
Any differences that are found tend to reflect strength and balance issues or speed
and accuracy of performance, rather than overall motor control.
Practical relevance. A number of studies are of theoretical rather than practical
relevance. Currently many researchers are interested in the detailed way in which
movements are carried out by individuals with Down syndrome and they measure differences
in the angles of joint movements, take measures of the actual activation patterns
of muscles, or study the differences in patterns of gait. Most of these studies
indicate largely normal movement patterns. [10,14,15,22]
Some do indicate difference in muscle activation patterns[9,13,15] however, since no
one has conscious control over the sequence of actions of muscles when moving, these
studies have little practical relevance.
The pattern of motor development for children and adults with Down syndrome
One of the important issues in the study of motor development in people with Down
syndrome is whether there is delay in achieving milestones and/or whether movements
are abnormal or not properly suited for their purpose. Some of the relevant research
is considered in this section.
Development is the same but delayed
Motor development for children with Down syndrome is usually significantly delayed.
All the basic motor skills are achieved by infants and children with Down syndrome
in the same order, but usually at significantly older ages when compared with typically
developing infants and children. [5-8]
This is illustrated by the examples given in Table 1.

There is increased variability
There is greater variability in the basic motor progress of children with Down syndrome,
when compared with typically developing children. For example the average age for
walking in typically developing children is 13 months and the range is 9-17 months,
while the average age for walking in children with Down syndrome is 24 months and
the range is 13-48 months.
Clumsiness and refinement of movements
Many movements continue to seem somewhat 'clumsy' in individuals with Down syndrome. It takes them longer to improve their skills and
they may not reach the same levels of fine coordination, but the levels they do
achieve will usually be adequate for successful performance.
More difficulty with balance and strength
A number of studies [2,10,11] indicate that balance is a particular difficulty
and continues to be a weakness in teenage years.
This may explain why many young people with Down syndrome find riding a bicycle
difficult to master. Some children do become competent on two wheels but many do
not achieve this, though they may be very competent on a tricycle.
Strength also continues to be lower even when the comparison is with young people
of similar general mental abilities. The explanation for this is not clear. Everyone
increases their muscle strength through active movement and it could be that individuals
with Down syndrome engage in less active movement, although there is no direct evidence
of this. The babies, toddlers and children that we see regularly in our preschool
and school services seem to us to be quite active. It could be that children with
Down syndrome need more exercise to reach the same levels of strength.
Slower reaction times
When teenagers and adults with Down syndrome are asked to perform motor tasks in
experimental situations, such as tapping the right button when the red light comes
on or tapping the left button when the green button comes on, their reaction times
are slower compared with mental age matched controls.[14,15]
Slower movement times
Some studies have also reported slower times (compared with mental age matched controls)
for the movement component of tasks as well as the reaction time.[14,15] The movement time would be the time taken from
initiating movement to reaching the end point of the movement â€“ for example, the
time taken from initiating the movement to completing the tap in the reaction time
Practice improves performance
Data from experimental studies requiring fine motor tasks to be carried out [15,16] and from real
life studies of activities such as running, 
report significant improvement in the performance of tasks with practice â€“ improvements
in both speed and accuracy of movements. However, some of these studies concluded
that individuals with Down syndrome require about twice as much practice to reach
the same level as typically developing individuals of the same mental age. They
seem to need more practice to establish motor programmes.
Some experimental studies have shown that adults with Down syndrome are more successful
at learning new movements in response to visual cues than to verbal instructions. It has been suggested that this may reflect different
brain organisation for movement control,
but this hypothesis needs more research. The implication of this is that children
and adults may learn new skills better by modelling or copying them than by being
given verbal instructions. .
Why this profile of development?
At the present time, we do not have enough knowledge about the reasons for these
features of motor development but we do have several facts which may provide some
clues and guidance for more effective intervention.
Closely linked to mental age
Both the descriptive studies of children's progress and some experimental studies
of motor skills in adults identify that the motor performance of individuals with
Down syndrome is closely linked to their general cognitive progress. In other words,
for gross motor, fine motor and experimental tasks, they perform like younger children
with the same cognitive or mental age. This suggests delayed rather than different
For example, one American study charted the progress of 15 children with Down syndrome
who were 7 to 10 years of age, and who had had the advantage of well-organised early
intervention and education. The findings in Table 2 show
the close relationship between their mental and motor progress. For the reader interested
in the data, the correlations between the fine motor and gross motor skills and
mental age are both .64 and statistically highly significant.
A study of teenagers also showed the close link between motor skills and mental
Table 2: Relationship between mental and motor progress
3y 3m - 6y 8m
Gross motor age
3y 5m - 6y 0m
Fine motor age
4y 2m - 6y 2m
(The fine motor scores are based on 12 children, as three children with mental ages
between 3 years 3 months to 3 years 9 months were not tested on the fine motor scale.)
The reason for the close association of overall mental and motor development is
not clear. It may reflect that the control of motor skills is largely a central
nervous system activity and that brain functions play a central role in motor development
in the same way as they do in cognitive development. It could be that both mental
and motor development are delayed by similar differences in brain processes. One
of these differences could be speed of information processing in the brain. Another
could be the ability to establish learned programmes in the brain. A number of studies
have highlighted the inconsistent performance of children with Down syndrome on
both cognitive and language tasks. It seems to take them longer (i.e. they need
more practice) to effectively consolidate new learning.
More dependent on visual feedback
Researchers have reported that children and adults with Down syndrome rely more
on visual feedback while carrying out a task than typically developing individuals.
They may need to rely to a greater extent on visual feedback because they take much
longer to establish learned motor programmes for the task. This can make their performance
seem as if they are tackling each repetition of the task as if they have not performed
it before. It also means that their pattern of movement may be jerky and inconsistent
from one time to the next even though they can actually perform the task correctly.
This finding could explain longer movement times because, as a learned programme
is established, the sequence of movements needed can be performed more quickly.
As already identified, there is some evidence that balance may be a particular difficulty
for individuals with Down syndrome. In one experimental study, the balancing abilities
of infants with Down syndrome were compared with typically developing infants and
the two groups were carefully matched for their ability to stand unsupported. The infants were put into a small room
in which the floor was stable but the walls could be moved to give the impression
of the room tilting. All the infants reacted as if the floor was also tilting by
leaning, swaying, staggering or falling, that is, they reacted as if to stop themselves
from falling even though the floor did not move. The visual information suggested
they were being tilted even though the vestibular information and d proprioceptive
feedback would not have suggested this.
The children with Down syndrome were more affected and made larger postural adjustments
than the typically developing children. Both groups of children improved as they
increased their experience of walking and after some 12 months of walking the typically
developing children were finally able to stay stable in the tilting room and not
react to the false visual cues. The children with Down syndrome needed longer to
become stable and did not show complete stability after a year or more of walking
experience, even though they were improving. The authors suggest that these findings
indicate that children with Down syndrome are more dependent on visual cues to judge
body position than typically developing children at the same stage of walking, possibly
indicating that their vestibular system is not as efficient at this point.
There is other evidence to suggest that balance continues to be an area of specific
difficulty into the teenage years. In an Australian study of the motor skills of
81 teenagers, balance was the weakest area
and still at a 4 year level when their other motor skills range from 5 to 9 year
levels. Their mean mental age was 4 years 9 months and therefore most of the motor
skills for the group were higher than might be expected, with response speed at
the same level as mental age and only balance lower than mental age. There was considerable
variability in motor skills between individuals and, as in other studies, mental
and motor skills were related. Individuals with lower mental ages tended to have
lower motor skill scores, and vice versa. .
Many authors assume that the profile of motor development in Down syndrome is largely
the result of physical differences, but the evidence for this point of view is limited.
Almost every discussion of motor development in children with Down syndrome starts
with descriptions of hypotonia and lax ligaments, and suggests that they are to
blame for the motor delays.
Hypotonia and lax ligaments
Many newborn children with Down syndrome have very flaccid muscles and are described
as 'floppy'. There are many specific disorders which are associated with the birth
of 'floppy' infants; in some cases this disappears as the child develops and in
some cases they remain in this 'floppy' state. There are a few follow up studies
of infants with Down syndrome and it seems that this infant floppiness does improve
over time. However, there is a fairly widespread belief that the children remain
with a degree of hypotonia and this state is often invoked as being responsible
for much of the 'poor' motor function seen in people with Down syndrome.
However, this is a rather controversial issue since there is no proper agreement
as to the definition of hypotonia and there is no consensus as to how to measure
it. In addition, some recent studies have demonstrated that the hypotonia seen when
children and adults with Down syndrome are not moving (i.e. their tendency to have
more 'floppy' muscles at rest) does not actually impair coordinated movement.[see
It is generally accepted that ligaments and tendons in individuals with Down syndrome
are more 'stretchy' than is usual. This would explain why they are able to move
their joints into extreme positions. However, research indicates that this does
not prevent control of the joints to perform ordinary movements.[4,15]
Clearly, a great deal of research needs to be done to clarify the different contributions
of the stretchiness of ligaments and tendons, the strength of the muscles, the 'tone'
of the muscles and the contribution of the nervous input to the greater picture
of motor function.
Some authors rightly draw attention to a number of conditions that are more common
in individuals with Down syndrome and which may affect a child's or adult's ability
to be active.[1,2] These
include heart conditions, , underactive thyroid function, vision and hearing issues,
and obesity. It will be important to take account of health factors for individual
children and adults when considering active sports but most will not prevent progress
in basic gross or fine motor skills. The relevance of each of these illness conditions
for activity will be the same as it is in the rest of the population.
The movement skills of children with Down syndrome are largely delayed rather than
The movement skills of children with Down syndrome are largely delayed rather than
different. They progress at the same pace as their general mental development. They
may take longer and need more practice to improve their performance and they may
continue to have more difficulty with tasks requiring balance. Most children achieve
competence in all everyday gross and fine motor skills even though they develop
more slowly. Despite the presence of lax ligaments and possible hypotonia, there
is little evidence that they impair controlled movements as the central nervous
system controls all movement and compensates for such variables.
Interventions for basic skills
There are very few evaluations of therapy aimed at improving or accelerating the
development of basic skills. Some early intervention
programmes which target all aspects of development indicate gains in motor development
with milestones reached earlier. This
may be because babies are encouraged to be more active and interested in their environment,
and encouraged to play and to move. .
One evaluation of a common form of physiotherapy reported no significant gains in
motor development for infants in therapy compared with infants not receiving therapy.
 Another recent study evaluated a very specific
therapy to encourage walking by placing infants on a treadmill for up to 8 minutes
a day from the time that they could sit without support.
The treadmill infants walked on average 101 days earlier than a comparison group,
presumably as a result of this increased practice. .
We found no evaluations of the adaptations and advice offered to improve gross or
fine motor skills. However, many practical aids such as the appropriate size of
chair and table, special grips for spoons, pens and pencils, and spring loaded scissors
may be helpful in giving a child improved opportunities to practise. In addition,
many practical programmes provide ideas for activities which will encourage a child
Activities designed to increase muscle strength of the whole body and of the hands,
are likely to be beneficial, as are activities that will improve balance such as
walking on a beam (at ground level), hopping, and playing football.
This lack of research evidence does not, of course, mean that babies and children
do not necessarily benefit from the recommendations given in books of practical
advice â€“ we do not know because the studies have not been done. However, the benefits
are likely to be mainly the result of providing games and activities which encourage
and increase active movement therefore increasing the child's amount of practice.
Practice allows the central nervous system to develop more effective motor programmes
for smoother and more coordinated movement.
Interventions for recreational skills
We also found no data on the numbers of teenagers or adults who become competent
in recreational skills or any studies documenting the effects of teaching such skills
to a representative group. There are a number of articles and chapters encouraging
educators to improve the opportunities for children, teenagers and adults to enjoy
a wide range of sporting and recreational activities and identifying the social
and health benefits. We would entirely agree with this advice, as it applies to
everyone, but we would benefit from more information on successful programmes and
some actual measurement of the benefits.
Some physiotherapists suggest that the main aim of therapy in infancy is to prevent
abnormal postures and gait, which may be
the result of lax ligaments, such as widely splayed hips when sitting, a wide based
gait or turning feet out when walking. However, as we have already discussed, some
of the most knowledgeable current researchers in the area argue that 'abnormalities'
in the way movements are seen to be carried out may be necessary adaptations at
particular stages, for example, to enable children to maintain their balance.[9,13] They argue that the
movement seen may be the best adaptation the child or adult can make and that we
should not be trying to push them towards 'normal' postures and styles of movement.
One concern we have is that therapy may not always seem to take account of the child's
developmental stage â€“ the child with Down syndrome may be showing immature styles
of movement that are seen in younger children when they begin to use the same movements.
In addition, because children with Down syndrome progress more slowly they may use
immature styles for longer and need more practice to improve and gain better control
One concern we have about supportive aids that restrict movement is that they prevent
the child from being able to control the restricted joint and muscles. This prevents
the practice of effective control of the movement and it will prevent gains in muscle
strength. However, at the same time we do not know if any lasting harm comes from
continuing to use 'abnormal' movements such as crab crawling with the knees out
sideways to the body and hips rotated. It has been suggested that this may lead
to long term damage of hip joints but no one actually knows if this is true as there
are no long term follow up studies. The body is a dynamic and flexible system and
possibly no harm comes from these actions in the long term.
It seems that we have no real evidence that interventions other than encouraging
and increasing the opportunities for active movement influence motor progress.
For basic skills â€“ from infancy
Encourage active movement
Since the most important factor in improving movement is the control from the brain,
it is important to find fun ways to encourage infants and children to initiate their
own movements. This applies to babies and toddlers when learning all the basic skills
such as rolling, reaching, grasping, sitting, standing, walking and feeding.
Fun activities then need to be encouraged as often as possible to give the child
practice. Some activities may need support such as walking. When babies bounce on
parents' knees, they are strengthening their legs with the help of support before
they can stand. Gaining balance and posture control for walking seems to take quite
a while and practice in walking with a truck to push or supervised practice for
short periods in a baby-walker may be beneficial. Baby bouncers will also strengthen
the legs if used for brief, supervised sessions. We know that many professionals
advise against these aids, but if they are used wisely they can increase the child's
opportunity to practice walking, as the treadmill study did.
Choose activities to help balance and strength
All active movement will be improving balance and strength, but it is also possible
to think of particular activities to target one or the other. Supervised trampolining
will improve balance and strength, for example, as will skipping, hopping, jumping
and kicking a ball. Hand gym exercises (e.g. squeezing ball of different textures)
will improve hand strength.
Teach by modelling
Research indicates that it is more effective to teach children with Down syndrome
by modelling the activity than by giving verbal instructions. This suggests that
children will learn more effectively by being able to imitate or copy correct actions.
Encourage fine motor skills
While many young people take time to develop writing and drawing skills, in our
experience it is worth continuing to practise at all ages. Drawing, painting and
colouring are described as a favourite activities by many teenagers and we know
of many accomplished artists in different countries who show technical talent and
considerable artistic expression in their art. Hand-writing often continues to improve
into adult life.
Enjoying active sports and dance will bring many benefits for health and social
contact in addition to the pleasure, self-confidence and pride that may be gained
from the activity. Success at sporting activities often seem linked with family
interests and the opportunity to start early and engage in high levels of practice.
We know individuals who are exceptionally good skiers or swimmers, for example,
and in each case their family gave them the opportunity to start early. Karen Gaffney,
a young woman with exceptional swimming ability and stamina, has swum in an English
Channel relay and her achievements can be found on her website (
http://www.karengaffneyfoundation.com/ ). Dancing is an activity that is
enjoyed by almost all the individuals with Down syndrome that we know and has the
potential for enjoyment whatever level of skill a person has achieved. Almost everyone
enjoys a disco, while some achieve considerable skill in ballet and many display
great talent in emotional expression through dance and mime.
It may be important to start activities such as swimming and gymnastics early. Many
communities have opportunities for preschoolers to begin these activities as well
as dancing. All the ordinary park games will also help, for example running, playing
football, climbing and using swings.
Teach by modelling
The advice to teach by demonstration is equally important for sporting and recreational
activities. We have observed this in school physical education lessons and in dancing
classes. Children with Down syndrome do not seem to find it easy to listen to or
follow the teacher's verbal instruction â€“ rather, they watch the other children
and copy them. In a dancing class, the teacher often does demonstrate the steps
but in school physical education lessons, much of the instruction is verbal and
this may be much less effective.
Many communities have clubs for sport and recreation, and some teenagers and adults
will enjoy inclusive facilities but some will prefer to join clubs for others with
intellectual disability or the Special Olympics so that they have a chance to shine
at the sport and to find close friendships.
Follow individual interests
With more children with Down syndrome being educated in mainstream school, they
will have the chance to join in a wider range of activities than may be available
in many special schools. This will provide greater chances to find out what they
enjoy and where their talents lie.
It is never too late
One of us has a daughter with Down syndrome who walked very late (4 years) and had
a 'poor gait', 'flat feet' and 'poor' posture throughout her childhood. We are not
a sporty family and she led a rather sedentary life until she joined the Special
Olympics team at the age of 21 and started training for running events. She then
walked with a straight back rather than a slouch, lost her 'flat feet' and improved
the 'normality' of her gait. (She also lost weight!) She also became quite a good
runner and won some medals in Special Olympic events. She was very proud of these
achievements. This suggests two points â€“ it is never too late to improve the way
basic skills may be performed and the best way to improve is through ordinary activity
and exercise. It is also never too late to think of encouraging adults to become
