This research is implemented to assess the level of improvement in dorsal flexion from a transcutaneous electrostimulation program combined with conventional conventional rehabilitation on the stiffness of the paralyzed leg of the hemiplegic subject post-stroke. This study carried out in the city of Porto-Novo focused on 14 hemiplegic subjects. It is an intervention research carried out in the Sport-Health-Service (3S) fitness center in Porto-Novo and at the Biomechanics and Performance Laboratory (LaBioP) of the National Institute of Physical Education and Sport (INJEPS). The results obtained allow us to affirm that the integration of ES into the therapeutic arsenal of hemiplegic subjects increases the electrical activity of the anterior tibial muscles and common long extensor of the toes; main muscles of the dorsal flexion of the foot. Therefore; it improves flexibility of the ankle. In addition to traditional muscle building techniques, we postulate that electrical stimulation contributes significantly to motor rehabilitation (walking autonomy) of the hemiplegic subject after stroke. Specifically, we note that the strength deficit after the stroke contributes significantly to the limitation of functional capacities. Electrostimulation combined with conventional rehabilitation contributes to limiting the degradation of this by improving muscle strength.This research is implemented to assess the level of improvement in dorsal flexion from a transcutaneous electrostimulation program combined with conventional conventional rehabilitation on the stiffness of the paralyzed leg of the hemiplegic subject post-stroke.
