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

Centre Hospitalier Universitaire de Saint Etienne1 enrolled

Overview

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.

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.

Conditions

Cerebral Palsy, Spastic Children, Only

Interventions

isokinetic dynamometer with ultrasoundDIAGNOSTIC_TEST

children are lying prone on a isokinetic dynamometer with ultrasound which stretches spastic and paretic plantarflexors muscles very slowly until maximal torque tolerated. The parameters can be measured.

Visual Analog Scale (VAS)OTHER

the discomfort level will be measured by Visual Analog Scale (VAS) completed by children. 0 = no discomfort and 10 = maximum discomfort

StretchingDIAGNOSTIC_TEST

the ankle of children will be mobilized for 5 minutes (first two weeks) to 10 minutes (last two weeks).
