Effects of a Program of Physical Exercise and Electrotherapy on Muscle Strength in Subjects of the Fourth Age

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine whether neuromuscular electrical stimulation, strengthening exercises, or combination of both over lower limbs are effective in the improvement of the stability fundamentally against falls, greater independence and, therefore, better quality of life in elderly over 75 years.
