Abstract
A single channel neuromuscular electrical stimulation (NMES) device for the prevention of deep vein thrombosis (DVT), pulmonary embolism (PE), lower extremity edema, and other associated conditions by electrical stimulation of the muscles of the foot muscles. An electrical signal generator produces a square wave pattern of variable frequency, duration, intensity, ramp time, and stimulation on-off cycle. Surface electrodes are positioned over the foot muscles and are attached to the stimulator by various means. The stimulator is programmed in a manner to stimulate the foot muscles to reduce pooling of the blood in the soleal veins of the calf This is accomplished by only stimulating the soles of the feet.
