The Impact of Inspiratory Muscle Training on Respiratory Function and Functional Capacity in Trainable Intellectually...

Area of Science:

• Pediatrics
• Rehabilitation Medicine
• Neurology

Background:

• Children with intellectual disabilities often exhibit impaired respiratory function and reduced physical capacity.
• Limited research exists on targeted interventions to enhance respiratory and functional outcomes in this population.

Purpose of the Study:

• To investigate the effects of inspiratory muscle training (IMT) on respiratory functions, balance, and functional capacity in children with trainable intellectual disabilities.

Main Methods:

• A randomized controlled trial involving 30 children (8-17 years) with intellectual disabilities.
• Participants were assigned to an experimental (IMT) or control (conventional physiotherapy) group for 8 weeks.
• Assessments included spirometry, 6-minute walk test (6MWT), and Berg Balance Scale (BBS).

Main Results:

• Significant improvements were observed in the IMT group for 6MWT, BBS, FEV₁, FVC, and MEP.
• Both groups showed improvements over time, but the IMT group demonstrated significant time × group interactions for key functional and respiratory measures.
• Maximal inspiratory pressure showed a significant main effect of time but no significant group or interaction effects.

Conclusions:

• Inspiratory muscle training is a viable and effective intervention for improving respiratory function, functional capacity, and balance in children with intellectual disabilities.
• IMT offers a promising approach to enhance the physical well-being of individuals with intellectual disabilities.
