Relationships between respiratory muscle strength and daily living function in children with cerebral palsy.
Weak cough and breathing pressure predict lower self-care and social scores in kids with CP—screen breathing when daily goals lag.
01Research in Context
What this study did
Wang et al. (2012) tested how strong breathing muscles relate to daily skills in kids with cerebral palsy.
They used simple hand-held tools to measure cough force and breathing pressure.
Parents also filled out a daily-living checklist about self-care and social play.
What they found
Weaker cough and lower breathing pressure lined up with lower self-care and social scores.
The link was modest but clear—kids who could not cough hard needed more help with dressing, eating, and talking to friends.
How this fits with other research
van Wely et al. (2020) extends this view by showing that low teenage participation and motor skills forecast poor adult participation 13 years later.
McIntyre et al. (2017) and Kerem-Günel et al. (2023) echo the theme: they link gross-motor, hand, and communication levels to family fun and social play.
Together the papers build one story—physical capacity at any age predicts how much kids with CP join in life.
Why it matters
If a child with CP is stalling on self-care or shy in peer games, check breathing strength. A quick cough test takes two minutes and tells you if weak core muscles are part of the problem. Add breath-play games, blowing bubbles, or straw races to your plan. Stronger lungs can support stronger daily living.

03Original abstract
Cerebral palsy (CP) is a common childhood disorder characterized by motor disability. Children with CP are at risk of developing significant respiratory problems associated with insufficient respiratory muscle strength. It is crucial to identify important factors which are associated with the limitations in daily living function in such children. Hence, the aim of this study was to investigate the relationship between respiratory muscle strength and daily living function in children with CP. The participants were 30 children with CP (M±SD age, 8.7±2.1 years) and 30 children with typical development (M±SD age, 8.3±0.9 years). Respiratory muscle strength was measured by maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) for the both groups of children. Children with CP were also assessed on daily living function with the subscales of Pediatric Evaluation of Disability Inventory (PEDI), the Functional Skills Scales (PEDI-FSS) and the Caregiver Assistance Scale (PEDI-CAS). Results show that, compared to the children with typical development, the MIP and MEP in the CP group were significantly lower (p=.003 and p=.001, respectively). In the CP group, MIP and MEP were correlated to two of the three PEDI-FSS domain scores (r=.43-.53, p<.05) but not with the three PEDI-CAS domain scores. MET explained 19% of the variance in the self-care domain score of PEDI-FSS. MEP also explained 15% of the variance in the social domain score of PEDI-FSS. The results of this study demonstrate that respiratory muscle strength in children with CP is correlated positively to their capability levels of daily living self-care and social function, and we suggest this should be taken into account when planning intervention to improving ability of daily living function for children with CP.
