If you have a child with developmental delay, physiotherapy will often play an important role in supporting them to gain independence and reach their full potential. Our guide explains what you need to know about physiotherapy for developmental delays, including the global developmental delay definition, what causes it, and how paediatric physiotherapy can help children reach their goals.

What is Global Developmental Delay?

Children who are developing typically achieve certain milestones at around the same time as their peers. They also reach these milestones in a specific order over time. For example, they learn to babble before they learn to talk.

If your child has developmental delay, it means they are taking longer to reach these developmental milestones than other children. Developmental delay may affect one area of development, such as speech, social or motor (movement) skills.

Sometimes, developmental delays have a significant effect on several aspects of a child’s development. In children younger than five years of age, global developmental delay is defined as a delay in two or more developmental areas:

  • gross/fine motor skills
  • speech/language
  • cognition
  • personal/social
  • activities of daily living[i].

Developmental delays are common in early childhood, affecting around 10%–15% of preschool children, with global developmental delays occurring in 1%–3% of children this age[ii].

Developmental delay in children can be difficult to recognise because all children develop at different rates. A child who is developmentally delayed may ‘recover’ and catch up with their peers. In other children, early developmental delay can be the first indicator of disability or longer-term challenges.

Global developmental delay causes

Causes of developmental delay include genetic and environmental factors[iii].


Developmental delay can occur in children who are born with some genetic syndromes, including:


A wide range of environmental factors can lead to developmental delays. These include:

  • infections or exposure to toxins in the womb
  • premature birth
  • birth trauma (which can lead to conditions such as cerebral palsy)
  • infections or illnesses after birth
  • head trauma in early childhood
  • malnutrition.

In many children with a developmental delay, no specific cause can be identified.

Global Developmental Delay Motor Symptoms

Motor development refers to a child’s ability to use their muscles and move around. Typically developing children reach motor development milestones in a specific order within certain timeframes. If children take longer than expected to achieve these milestones, it could indicate they have a delay in the area of motor development. This may involve development of: 

Gross motor skills – gross motor delays affect big muscles in the legs, arms or trunk, leading to difficulties with activities like rolling, sitting, crawling and walking.

Fine motor skills – fine motor delays affect small muscles, like those in the hands, which leads to difficulties with tasks such as handwriting, tying shoelaces and grasping objects.

Other signs of motor delay

Children with a motor developmental delay might also have:

  • stiffness in their arms, legs or trunk
  • low muscle tone (‘floppiness’) compared to children of a similar age
  • difficulty using one side of their body
  • clumsy or poorly coordinated movement
  • balance problems.

The symptoms of developmental delay can affect a child’s ability to participate in their families, communities, and educational settings. Early childhood early intervention aims to provide support as soon as possible, so children with developmental delay have the strongest chance of achieving the best possible outcomes.

Developmental delay physiotherapy management: an overview

As university-qualified allied health professionals, physiotherapists have extensive training in movement and function. This includes substantial training in how bones, muscles, and the nervous system develop, and what can cause developmental delays in children.

For children with developmental delays, physiotherapy aims to help children achieve goals such as greater independence, quality of life, and ability to participate at home, in early childhood education, and in leisure and community activities.

Paediatric physiotherapists use a range of techniques and therapeutic supports designed to:

increase muscle strength and flexibility

improve joint range of movement

encourage normal movement patterns

help children keep up with their peers

support achievement of movement milestones

improve balance, posture and coordination

promote independence with daily living activities

Ideally, pediatric physiotherapy for developmental delay should start as early as possible. This is because young children’s growing brains and bodies are highly responsive to their environment. Early intervention harnesses the potential of this responsiveness to support optimal growth and development.

The NDIS early childhood approach recognises how important it is for children with developmental delay to access early intervention support services. For this reason, your child doesn’t need to have a formal diagnosis of developmental delay or disability to access support if they are younger than six.

How paediatric physiotherapy can help a child with developmental delay

Motor developmental delay can have a wide range of consequences, so physiotherapy for children with developmental delay involves various techniques and strategies. Physiotherapists prescribe programs tailored to the needs and goals of each child and their family/caregivers. Your physiotherapist will help your child work towards their goals using recognised, evidence-based therapies.

Examples of physiotherapy treatment for developmental delay include:

Strength training

Muscle weakness is a common feature of developmental delay. Physiotherapy treatment often includes exercises designed to improve muscle strength. These will be focused on improving your child’s function, such as their ability to:

  • stand up, walk or run
  • sit up in a chair
  • maintain their balance
  • play a sport
  • hold a pencil and write
  • grasp objects, such as a cup or their toothbrush.

Motor skill training

Your physio might prescribe exercises or apply techniques designed to help your child achieve movement milestones, such as the ability to sit, crawl, stand and walk.

Balance training

Some children with developmental delay have trouble keeping their balance, especially if they have low muscle tone or weakness in the leg and trunk muscles. Along with exercises to improve muscle strength, children’s physiotherapy might include activities designed to help your child cope with balance challenges.

For example, they might practise:

  • balancing on one leg
  • shifting their weight from one foot to the other
  • maintaining their balance while performing different movements, such as kicking or walking heel to toe.

Flexibility exercises

Your child’s physio might include muscle stretching to improve flexibility and range of movement and help prevent contractures.

Proprioceptive training

This involves training to help your child recognise where their body is in space, both at rest and while they are moving.

Movement and co-ordination training

Some children with developmental delays have difficulties with specific movement patterns. For example, they may find it hard to move their opposite arm and leg or turn their head or trunk. Physiotherapy can support children to develop better patterns of movement and to co-ordinate movement of different body parts. This can help with everyday activities as well as those that require higher levels of co-ordination, such as sports.

Assistive technologies

Physios may be involved in prescribing assistive devices to support your child’s independence and ability to participate in things that are important to them. For example, they might need a specific type of seat or cushion to help them sit upright at school. Or they may need to use a wheelchair to access their school or community or to participate in sports or hobbies.

Training support people

Families and carers play an essential part in supporting a child with global developmental delay to reach their goals. Your physiotherapist might train you to support your child with:

  • completing a home exercise program
  • play-based movement activities
  • gaining independence with everyday activities
  • using assistive devices.
