Tremor attenuation based on joint impedance modulation using FES

In this work we describe experiments to validate an alternative method to attenuate the effects of pathological tremor using FES. The method is based on co-contracting antagonist muscles in order to increase joint impedance and hence improve the joint stability for trembling movements. Both open-loop and closed-loop trials involving tremor patients and healthy subjects were conducted, and the results indicate that an effective functional benefit may be obtained.
