The effects of a strengthening program on walking and stair-climbing ability of adolescents and young adults with cerebral palsy: a randomized controlled trial

Purpose. the study aim was to examine the effects of a 10-week school-based strengthening program on walking and stair-climbing ability of adolescents and young adults with cerebral palsy. Methods. Overall, 35 participants, aged 12–19 years, were classified in 3 levels in accordance with the Gross Motor Function Classification System and randomly assigned to the experimental and control group. the experimental group participated in a 10-week progressive resistance exercise program during the adapted physical education class and performed functional strength exercises (sit-to-stand, lateral and front step-up), with a frequency of 3 times per week. the experimental and control groups continued their usual care at school regarding physical therapy and/or occupational therapy. Stair-climbing ability was assessed with the timed Up and Down Stairs test and walking ability was evaluated with the 10-m walk test and the 1-minute walk test. Results. there was a significant between-group improvement for stair-climbing ability favouring the intervention group ( F = 6.519, p = 0.016, 2 = 0.169), whereas walking ability as assessed with the 10-m walk test and the 1-minute walk test remained unchanged. Conclusions. A functional strengthening program administered in adolescents and young adults with cerebral palsy may positively influence their stair-climbing ability, without any adverse effects.
