Abstract : 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.
