Pathological tremor

Tremor online characterization + voluntary motion filtering

Demo of proposed real-time algorithm to characterize pathological tremor, while filtering voluntary motion components. The main application of this algorithm is on active tremor compensation systems.

Using FES to control joint dynamics: system identification

In this demo we show an experiment to estimate both passive and active parameters of the wrist joint controlled by surface electrical stimulation.

Tremor compensation using FES: co-contraction to increase joint stability

Demo of a tremor compensation system using electrical stimulation. Based on information from portable sensors, the controller applies higher currents for stronger tremors. Tremor is induced with an auxiliary stimulator.
