Study: NCT05899244

Intervention type: OTHER
Group type: EXPERIMENTAL
Intervention: muscle streching exercice
Description: For this exercice the participant will have to place the foot of the stretched leg on a step while maintaining his knee in extension.~From this starting position the patient will have to do a pelvic anterior tilt while keeping is back straight and his gaze horizontal until the movement induce a feeling of stretching in the posterior part of the thigh.

Intervention: Slider
Description: In order to define the starting position for a slider, the participant will be positioned in lateral decubitus with the knee extended and will perform a hip flexion until a sensation of pain or stretching feeling appears on the posterior part of the thigh or of the knee. If the hip flexion does not induce a stretching sensation or pain, a dorsal ankle flexion is added. Once this position is defined the patient slightly reduces the amount of hip flexion until the stretching/pain sensation disappears.~From this starting position, to perform the slider: the subject performs a hip flexion movement and simultaneously a cervical extension movement, this corresponds to the outward movement. For the return movement the patient performs a hip extension and at the same time a cervical flexion. The slider technique must be pain free.

Group type: EXPERIMENTAL
Intervention: Tensioner
Description: The participant will be positioned in lateral decubitus with the knee extended and the hip, the cervical, thoracic and lumbar spine placed in neutral position.~For the outward movement, the participant will perform a hip flexion associated with a simultaneous movement of cervical extension until a sensation of pain or a stretching feeling appears on the posterior part of the thigh or of the knee.If this combined movements do not induce a stretching sensation or pain, a dorsal flexion of the ankle is added.~For the return movement, the participant will realize a hip extension simultaneously associated to a movement of extension of the cervical spine. If the dorsal flexion of the ankle was used during the outward movement, a movement plantar flexion of the ankle must be used in association to the movement of hip extension.
