Strength training in adolescent learners with cerebral palsy: a randomized controlled trial

Area of Science:

• Pediatric Rehabilitation
• Neuromuscular Disorders
• Biomechanical Analysis

Background:

• Cerebral palsy (CP) often affects gait and self-perception in adolescents.
• Strength training is a potential intervention to address functional limitations in individuals with CP.

Purpose of the Study:

• To assess the impact of an 8-week strength training program on gait, body image, and functional competence in adolescents with spastic cerebral palsy.
• To evaluate the effectiveness of using inexpensive, free weights and resistance devices in a school setting.

Main Methods:

• A randomized control trial was conducted with 31 independently ambulant senior learners with spastic cerebral palsy.
• An 8-week circuit-style strength training program (1-3 times/week) was implemented during school hours.
• Gait was analyzed using 3D motion capture, and perceptions of body image and functional competence were assessed via questionnaires.

Main Results:

• The strength training group showed significant improvement in crouch gait (P=0.05) and body image perception (P=0.01) compared to the control group.
• No significant changes were observed in walking velocity, cadence, stride length, or perceived functional ability.

Conclusions:

• School-based strength training programs utilizing accessible equipment can effectively improve crouch gait and body image perception in adolescents with cerebral palsy.
• This intervention demonstrates potential for enhancing physical and psychological well-being in this population.
