Efficacy of a Long Term, High Intensity and Long Time Stretch Training Program on Viscoelasticity Plantarflexors Muscle in Children With Cerebral Palsy (CP).

Not Applicable

Terminated

• Conditions: Cerebral Palsy, Spastic; Children, Only

• Registration Number: NCT03565172
• Lead Sponsor: Centre Hospitalier Universitaire de Saint Etienne

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.
