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. This study assess efficacy of an acute high intensity and long-time stretching session of plantarflexors muscle on their viscoelasticity properties and maximal dorsiflexion angle gain. Single stretching session is characterized by high intensity and long time (5 minutes).

Conditions

  • Cerebral Palsy

Interventions

OTHER

measurement evaluated with an isokinetic dynamometer

measurement of the maximum dorsiflexion angle in degrees evaluated on an isokinetic dynamometer

OTHER

measurement evaluated with an 2D ultrasound

* simultaneous recording of force torque, joint angle and myotendinous junction displacement in 2D ultrasound during 5 passive mobilization cycles of ankle flexion-extension at very low speed * recording of static images in 2D ultrasound representing the proximal insertion of the gastrocnemius muscle in the internal condyle of the femur, the myotendinous junction.

OTHER

assessment of the level of discomfort

visual analogue scale (0 = no discomfort and 10 = maximal discomfort)
