Study Overview
Brief Summary
Children with cerebral palsy present early in the childhood altered muscular properties, as soon as structural or stiffness. In the gastrocnemius muscle, altered muscular properties are characterized by short muscle belly length and increased stiffness which contribute to contracture and limiting joint range of motion.
Detailed Description
This study assess efficacy of a long term stretching program of plantarflexors muscle on their viscoelasticity properties and maximal dorsiflexion angle gain. Stretching program is characterized by 3 phases: baseline, intervention and follow-up.

Arms & Interventions
Children with spastic cerebral palsy
Children with spastic cerebral palsy will be included. They will have 3 phases:
- Baseline: 4, 5 or 6 evaluations
- Intervention: 9 evaluations before and after every stretching session
- Follow-up: 4, 5 or 6 evaluations
The evaluation part will be composed of isokinetic dynamometer with ultrasound and Visual Analog Scale (VAS). The number of evaluations at baseline and follow-up will be randomized before the study by Single Case Experimental Design (SCED) methodology.
Intervention: isokinetic dynamometer with ultrasound (Diagnostic Test)
