The Effect of Vibrotactile Stimulation on Parkinson's Tremor

Mechanical vibrations are applied at brief bursts of 80Hz that occur at the individual tremor frequency. Vibrations are delivered via a small device, which is worn on the wrist of the most-affected arm.

Mechanical vibrations are applied at 80Hz bursts at individual tremor frequency\*1.5. Vibrations are delivered via a small device, which is worn on the wrist of the most-affected arm.

Continuous 80Hz stimulation is applied via a small device worn on the wrist of the most-affected arm.

This intervention is applied during assessment of gait. Two devices are worn on both ankles which allows alternating stimulation of both ankles with brief bursts of 80 HZ at the individual step frequency plus or minus 10%.
