Feasibility study of a new medical device that will evaluate the usability and effectiveness of a cycle ergometer device associated with neuromuscular electrical stimulation (FES cycling). The study's objective is to evaluate the effect of the application of functional electrical stimulation of the new device on participants' quadriceps muscle strength in comparison to a medical device with similar characteristics and to a control group. Secondarily, the study will compare the usability of the two medical devices as evaluated by the participants and the therapists who apply the treatment, as well as the participants' satisfaction with the treatment, identifying possible adverse effects.
