New functional vibratory stimulation device for extremities in patients with stroke.

The utility of a new device that delivers functional vibratory stimulation to the extremities was studied in 13 patients with stroke. We hypothesized that vibratory stimulation of the hemiplegic lower limb would increase gait speed in these patients. The device consisted of one battery, two small vibrators and a connecting wire. The small vibrators were stabilized on the anterior tibial muscle and gluteus medius muscle by a bandage. An analysis of the effects of functional vibratory stimulation on hemiplegic lower limb on gait speed indicated that gait speed was greater during stimulation than without. These results suggest that the new device of functional vibratory stimulation is useful for treatment in patients with stroke.
