Influence of Fatigue on the Walking Pattern in Cerebral Palsy Patients.

To date, studies do not study the influence of external disturbing factors on the market. The main hypothesis is that the stopping of walking in paralyzed cerebral patients is mainly due to an increase in the energy cost of walking. The secondary objectives are to study the causes of the increase in the energy cost of walking (modification of muscle coordination / increase of co-activations, loss of strength, etc.). This study will use the GRAIL combining an instrumented treadmill, a motion capture system (Vicon System), an electromyographic system as well as a virtual environment projected on a 180 ° screen
