There is a need for an objective clinical analysis of the electrical response of the muscles of stroke patients’ paretic side and nonparetic side using functional electrical stimulation (FES) with an alternating current to confirm the degree of muscle degeneration. The subjects were ten stroke patients (five male and five female). The pad of an electrical stimulator was applied to the vastus lateralis and the vastus medialis regions to measure the amplitude of FES until the contractive muscle response to the electrical stimulation became visible. The amplitude of FES was significantly increased on the paretic side compared to that of the nonparetic side of hemiplegic stroke patients. Furthermore, the amplitude of paretic sides was significantly higher than that for nonparetic sides in female groups. This result suggests that stroke affects muscle contraction. When performing rehabilitation, the appropriate input for each stroke patient needs to be carefully considered.
