Effects of High-Intensity Muscle Strength Training and Stretching Exercises on Strength, Spasticity, Postural Alignment, and Participation in an Adolescent with Spastic Diplegic Cerebral Palsy: A Single-Subject Design

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.
