Electrical Muscle Stimulation on Muscle Stiffness and Functional Capacity in Post-menopausal Women

The aim of this study will be to determine the effects of different electrical muscle stimulation protocols on muscle stiffness and functional capacity in post-menopausal women. A randomized controlled clinical trial will be carried out. A total sample of 27 post-menopausal women will be recruited and divided into 3 groups which received high-frequency electrical muscle stimulation during 8 weeks, low-frequency electrical muscle stimulation during 8 weeks or no-intervention (control group). Outcome measurements will be stiffness assessed by sonoelastography and functional capacity assessed by the 30 seconds Chair-Stand Test before and after 8 weeks interventions.
