Muscle tone is the amount of tension (or resistance to movement) in muscles. Our muscle tone helps us to hold our bodies upright when we are sitting and standing. Changes in muscle tone are what enable us to move. Muscle tone also contributes to the control, speed and amount of movement we
Low muscle tone is used to describe muscles that are floppy, which is also known as hypotonia. Children with low muscle tone may need to put in more effort to get their muscles moving properly when they are doing an activity. They may also have difficulty maintaining good posture when sitting
or standing. Many children with low muscle tone have delays in their gross motor development (e.g. rolling, sitting, walking).
Low muscle tone may be caused by problems with the nerves or muscles. Often the low muscle tone is idiopathic, which means the cause is unknown.
If your child has low muscle tone, their muscles may seem to be floppy from birth. Your child may:
Sometimes, low muscle tone is diagnosed shortly after birth during newborn health checks or at maternal and child health checks. In other cases, low muscle tone becomes evident later, usually when gross motor development delays become more obvious. If you are concerned about your child's
muscle tone, see your maternal and child health nurse or GP.
You may be referred to a paediatrician, who may examine and investigate for possible underlying causes of the low muscle tone. An occupational therapist or physiotherapist may become involved, to advise on treatment and activities to help improve your child's muscle tone.
Most children with idiopathic low muscle tone will naturally improve over time, without any long-term impact on their physical strength and abilities. However, some people may experience muscle weakness into adulthood.
A physiotherapist or occupational therapist can offer strategies and suggestions to help your child maximise their muscle tone.
Warm-up activities can improve your child's endurance by helping to activate the muscles. It is important to encourage your child to do a warm-up activity every day. While these activities will not lead to a permanent change in your child's muscle tone, they will help your child know
what it is like to do everyday things using a more stable posture. Make the activities fun and exciting as this can help increase your child’s level of alertness and muscle tone.
For example, bouncing on a mini trampoline before sitting at a table to do a drawing may help your child to sit up straight rather than slump. If your child is slouching after they have started an activity, get them to stop what they are doing and have them do 10 star jumps to activate their
Squeezing and rolling playdough before writing may help your child to maintain their hold on the pencil and write for a longer period of time.
Your physiotherapist or occupational therapist will recommend suitable warm-up activities, but some other suggestions include:
Will my child grow out of her low muscle tone?
Most children with low muscle tone will demonstrate slower
gross motor development, but will ultimately catch up with their peers in time.
Occasionally, an underlying disorder may be the cause of the hypotonia. If your
child as an underlying condition, discuss this with your child's doctor.
What is floppy baby syndrome?
Floppy baby syndrome is not a syndrome at all. It is rather
a way of describing a newborn baby with low muscle tone. The term 'syndrome'
can be distressing for some parents and therefore using it is discouraged.
If my child gets tired easily from doing day-to-day
activities, won't warm up activities make him even more tired?
No, because the warm-up exercises train the muscles to
activate more quickly and maintain that activity for longer. For example,
warm-up activities can help your child's muscles get used to being in a better
position, such as standing in a good posture.
