Introduction

Trunk control plays a key role in how children move, sit, balance and participate in everyday tasks. These muscles help stabilise the body during activities such as climbing, running and handwriting. When trunk control is less developed, children may tire easily or find certain movements harder. Paediatric physiotherapists and Pilates practitioners use play-based and purposeful activities to support safe and age-appropriate skill development. This information is educational only and not a substitute for an individual assessment.

What Trunk Control Means

The term "trunk" refers to the coordinated activity of the deep abdominal muscles, spinal stabilisers, diaphragm and pelvic floor. These muscles work together to maintain posture and provide a stable foundation for limb movement. Research describes the trunk as essential for balance and efficient motor patterns, particularly during dynamic tasks. Some people may refer to this area as the "core", although clinicians often prefer terms such as trunk control, trunk strength or trunk stability. Understanding trunk function helps explain its importance in children’s development.

Why Trunk Strength Matters

A stable trunk supports upright sitting, which is important for learning tasks such as handwriting and concentration. Studies highlight that trunk stability contributes to gross motor milestones including rolling, sitting, crawling and early standing. Stronger trunk control also helps children change direction, jump, climb and engage confidently in sports. When postural control improves, children can allocate more energy to fine motor skills because they are not using excessive effort to stay upright. These foundations support participation across home, school and community life.

Evidence-Informed Benefits

Research suggests that trunk-focused activities may support balance, coordination and motor planning in children. Studies exploring paediatric therapy programs show that targeted strengthening can contribute to improved functional movement patterns. Pilates-based approaches have been associated with increased postural awareness and controlled movement in paediatric populations. While outcomes vary widely, these activities can be helpful when tailored to a child's abilities and needs. Evidence highlights the importance of individual assessment to ensure exercises are appropriate for development.

How Physiotherapy Supports Trunk Strength

Paediatric physiotherapists use play-based exercises to build trunk control in enjoyable and achievable ways. Activities can include crawling variations, climbing challenges, and movement sequences that encourage coordinated rotation. Physiotherapists may also use scooter boards, therapy balls or obstacle courses to help children practise balance and whole-body stabilisation. These sessions aim to develop confidence and movement efficiency rather than simply building strength. Programs are adapted to each child’s goals, interests and developmental stage to promote engagement.

Pilates for Children

Pilates-inspired programs can be supportive for children by teaching controlled movement, postural alignment and breathing coordination. Unlike high-impact activities, Pilates allows children time to notice how their bodies move and how their muscles activate. Sessions often incorporate props, imagination and playful challenges to maintain interest. The approach encourages slow and purposeful movement, which may help children build awareness of stability during everyday activities. Pilates is adaptable for many ages and abilities when delivered by trained professionals.

When to Seek Professional Support

A physiotherapy assessment may be helpful if a child consistently tires in seated tasks, avoids active play, or appears to have difficulty with balance or gross motor skills. Some children may have conditions or developmental differences that affect movement patterns and require targeted support. A trained professional can clarify what is happening and offer recommendations that match the child's needs. Families benefit from guidance that is personalised rather than generalised. Early advice can make participation in daily routines feel easier for children.

Frequently Asked Questions

Is trunk strengthening safe for children When exercises are developmentally appropriate and supervised by a trained professional, they can be safe.

Does Pilates improve posture Pilates may support postural awareness and trunk stability in some children.

Does every child need trunk exercises No, many children develop trunk control naturally through play.

Will strengthening the trunk fix all movement challenges Not always, because movement difficulties may have multiple contributing factors.
