The aim of this review was to analyse if strengthening interventions increase strength without increasing spasticity and improve activity, and is there any carryover after cessation in children and adolescents with cerebral palsy. Studies involving children with spastic cerebral palsy between school age and 20 years who underwent strengthening interventions that involved repetitive, strong, or effortful muscle contractions and progressed as ability changed, such as biofeedback, electrical stimulation, and progressive resistance exercise were included. Six studies were identified and five had data that could be included in a metaanalysis. Strengthening interventions had no effect on strength, no effect on walking speed, and had a small statistically-significant but not clinically-worthwhile effect on Gross Motor Function Measure.
In children and adolescents with cerebral palsy who are walking, the current evidence suggests that strengthening interventions are neither effective nor worthwhile.
