As physiotherapists, we often meet families whose children face challenges with movement, strength, or coordination. Sometimes the cause is a neuromuscular condition (NMD) – a group of disorders that affect how nerves and muscles work together.
Getting an early diagnosis and the right physiotherapy support can make a big difference to your child’s independence and quality of life.
Signs of Muscle Weakness in Children
Parents are usually the first to notice when something isn’t quite right. Some early signs of neuromuscular disease in children include:
- Difficulty holding up their head as a baby
- Delayed motor milestones such as sitting, crawling or walking
- Trouble running, climbing or jumping compared to other children
- Frequent falls, clumsy movements or tiring easily
- General muscle weakness
- Gowers Sign – when a child uses their hands on their thighs to push themselves up from the floor
If you notice any of these signs, it is worth speaking to a health professional.
Understanding Neuromuscular Disorders in Children
Neuromuscular disorders affect the way nerves and muscles communicate, making it harder for muscles to move properly. They vary widely, but some of the more common conditions include:
Spinal Muscular Atrophy (SMA)
SMA is a genetic condition where some nerve cells in the spinal cord don’t work properly, leading to weakness and muscle wasting. This usually starts in the hips and legs. Thanks to new medical treatments, children diagnosed early can now have much better outcomes. Physiotherapy for Spinal Muscular Atrophy focuses on early movement, equipment, and breathing support.
Charcot-Marie-Tooth Disease (CMT)
CMT affects the nerves in the arms and legs and often runs in families. Children may struggle with balance, walking or fine motor tasks such as handwriting. Weakness in the feet and hands is common, along with fatigue, pain and changes in posture. Physiotherapy for Charcot-Marie-Tooth disease often includes ankle strengthening, balance training and mobility aids.
Duchenne Muscular Dystrophy (DMD)
DMD mostly affects boys and symptoms usually appear between ages 3 and 5. Children may look clumsy, tire easily, or develop large calf muscles. Over time, weakness develops, especially in the hips and thighs. While there is no cure, treatments such as steroids and physiotherapy can help children stay active for longer.
An important note about exercise in DMD:
Because children with DMD lack dystrophin, their muscles are highly vulnerable to damage from eccentric contractions (where muscles lengthen while under load, like slowly lowering from a squat or walking downhill). These types of exercises should be avoided, as they can cause unnecessary muscle breakdown. A physiotherapist with experience in neuromuscular conditions will design safe programs that focus on protecting muscle health while encouraging activity.

How Physiotherapy Supports Children with Neuromuscular Conditions
Physiotherapists play a key role in managing neuromuscular disorders. Therapy is tailored to the child’s age, condition and daily needs. It may include:
- Play-based exercises to support motor development
- Stretching and splinting to reduce stiffness and contractures
- Mobility aids such as walkers, wheelchairs or scooters
- Strengthening exercises for safe muscle groups
- Breathing support and positioning advice
Examples of physiotherapy management for neuromuscular disease:
- In CMT, ankle strengthening and balance activities are a priority
- In SMA, early use of equipment and active movement support are key
- In DMD, programs are carefully structured to avoid muscle damage while keeping children mobile for as long as possible
Because each condition is different, it is important to work with a paediatric physiotherapist experienced in neuromuscular disorders.
Is Exercise Safe for Kids with Neuromuscular Disease?
Yes. Exercise is both safe and encouraged for children with neuromuscular conditions. The focus is on moderate, enjoyable activities such as:
- Walking or swimming
- Riding a bike or scooter
- Playing games with regular breaks
A simple way to check intensity is the “talk test”:
- Can sing while moving = low intensity
- Can talk but not sing = moderate (ideal)
- Can’t talk in full sentences = too intense
Heavy resistance training and eccentric exercise should be avoided in Duchenne Muscular Dystrophy, but most other gentle, fun activities are not only safe but recommended.
Managing Fatigue and Activity Levels
Children with neuromuscular conditions often get tired more easily. Physiotherapists use pacing strategies such as:
- Breaking activities into smaller parts
- Using regular rest breaks
- Modifying tasks to conserve energy
Mild muscle soreness for 24 to 48 hours after exercise is normal. If pain lasts longer than 72 hours or stops your child from doing their usual activities, their program may need to be adjusted.
Takeaways
If your child has a neuromuscular condition, movement and exercise are essential for maintaining independence, confidence and quality of life. Physiotherapy provides the guidance and support families need to keep children safe, active and happy doing the things they love.
Working with an experienced paediatric physiotherapist ensures your child receives a program tailored to their condition, whether it is Spinal Muscular Atrophy, Charcot-Marie-Tooth disease, Duchenne Muscular Dystrophy or another neuromuscular disorder.
