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.
Interventions
DIAGNOSTIC_TESTisokinetic dynamometer with ultrasound
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.
the discomfort level will be measured by Visual Analog Scale (VAS) completed by children. 0 = no discomfort and 10 = maximum discomfort
DIAGNOSTIC_TESTStretching
the ankle of children will be mobilized for 5 minutes (first two weeks) to 10 minutes (last two weeks).
