Clinical Trial 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).

Intervention

Other:
• measurement evaluated with an isokinetic dynamometer
measurement of the maximum dorsiflexion angle in degrees evaluated on an isokinetic dynamometer
• 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.
• assessment of the level of discomfort
visual analogue scale (0 = no discomfort and 10 = maximal discomfort)

Primary	slope of the torque curve force-ankle joint angle in the joint area -25° plantar flexion/maximum dorsal flexion		baseline
Secondary	Maximum dorsal flexion angle of ankle, knee in maximum extension position		at 5 minutes
Secondary	slope of the force-displacement torque curve myotendinous junction of the Sural Triceps in the articular sector -25° plantar flexion/maximum dorsal flexion		at 5 minutes
Secondary	lengths of the musculotendinous unit of the Triceps Sural muscle, the muscular body of the gastrocnemius muscle and the Achilles tendon in cm measured at rest, knee in maximum extension position, ankle angle in neutral plantar/dorsal flexion position.		at 5 minutes
Secondary	visual analogue scale of discomfort	0 = not discomfort and 10 = maximal discomfort	at 5 minutes
