title: The effect of electrical stimulation on quadriceps strength and thigh circumference in menisectomy patients.
abstract: The purpose of this study was to assess the effects of two training regimens: electrical stimulation and exercise versus exercise alone in increasing quadriceps strength and thigh circumference. Subjects were 21 postmenisectomy patients who were randomly assigned to one of the two groups. The experimental group received quadriceps stimulation 5 days/week for 3 weeks. Both groups maintained a knee rehabilitation program consisting of quadriceps and hamstrings isometric and isotonic strengthening exercises 3 days/week. Results indicated that electrical stimulation combined with a regular program of quadriceps exercise have a significant effect in strengthening the quadriceps at four different contraction speeds (1 20, 180, 240, and 300 degrees /sec). The control group exhibited significant strength gains only at the slower two speeds. Thus, electrical stimulation may be valuable in strengthening at high speeds of contraction. The thigh circumference changes were significant for both groups. J Orthop Sports Phys Ther 1986;8(3):143-146.
