This video by Dominic Munnelly shows how the patient is tested for mobility and functional movement by looking for sequential firings of the motor nerves. The purpose of sequential firings is to make sure the patient/athlete is moving properly so as to avoid injury by depending on compensation by stronger muscle groups.
Functional restoration requires the athlete to actually exercise while the Infrex FRM is on and stimulating motor nerves. The purpose of the exercises, coupled with high frequency electrical stimulation, is to complete full force voluntary movement involving the most motor nerves possible. Volitional movements by the patient incorporates the smaller diameter fibers and the Infrex high frequency electrotherapy machine activates the larger diameter fibers at the same time. The process is one of the reasons rehabilitation time is diminished considerably using athletic exercises with functional stimulation. Enjoy the video.
