ABSTRACT

PURPOSE: This study examined the effects of high-intensity (HI) muscle strength training and stretching exercises on muscle strength, spasticity, postural alignment, and participation in the activities of daily living (ADL) in an adolescent with cerebral palsy (CP). METHODS: The study used a single-subject design with a 16-week follow-up. After a three-week intervention-free period, a participant underwent five data collection sessions for the baseline measurements. Subsequently, stretching and HI strength training occurred three times weekly for 48 sessions, with the outcome measures collected weekly post-treatment. Final measurements were taken the day after the last session, and a follow-up assessment occurred six weeks post-study to assess the learning effects. RESULTS: After 16 weeks of treatment, the participant exhibited improved targeted muscle strength and postural alignment without increased spasticity. On the other hand, no significant change in participation in the ADL was observed. CONCLUSION: The research findings suggest that HI strength training and stretching exercises may contribute to improvements in muscle strength and body alignment without increased spasticity in an adolescent with CP, but it may not have a significant impact on participation in ADL.
