Évaluation du recrutement des muscles fessiers dans les exercices de rééducation chez le jeune paralysé cérébral

Gluteus muscles weakness, especially Gluteus Maximus and Gluteus Medius ones are frequently reported in Cerebral Palsy (CP) walking children. Thus, their reinforcement in rehabilitation is often justified. Many physiotherapy exercises solicit their recruitment, but their efficiency was not yet reported. Ten different exercises are assessed and compared using surface electromyography (EMGs). The activity of Gluteus Maximus and Gluteus Medius muscles was recorded in 18 CP and eight asymptomatic children while realizing those exercises. The levels of muscular activation were compared between each exercise, and the existence of patterns was sought in the group of CP children. CP children measures were also compared to those recorded for valid children. This study gives classification of the exercises with respect to their efficiency for the recruitment of Gluteus Medius and Gluteus Maximus. The activity of these muscles in the various phases of the exercises is stated. Finally selection criterions between the exercises are proposed according to rehabilitation objectives of the pelvic belt.
