About

The purpose of this study is to determine the effects of neuromuscular electrical stimulation (NMES) on neuromuscular and functional parameters in elderly with knee osteoarthritis.

The hypothesis is that NAMES is able to strengthen the quadriceps muscle and to improve healthy status of elderly with knee osteoarthritis.

Neuromuscular Electrical Stimulation (NMES)

Experimental group

Description:

The intervention was performed with subjects seated on a regular chair (hip and knee angles maintained at approximately 908), 3 times/week for a period of 8 weeks. NMES parameters included: rectangular biphasic symmetric current, pulse duration of 400 ms and stimulation frequency of 80 Hz.
