Repetitive control of electrical stimulation for tremor suppression
Repetitive control of electrical stimulation for tremor suppression
Tremor is a rapid uncontrollable back-and-forth movement of a body part often seen in patients with neurological conditions such as Multiple Sclerosis (MS) and Parkinson’s disease. This debilitating oscillation can be suppressed by applying functional electrical stimulation (FES) within a closedloop control system. However current implementations use classical control methods and have proved capable of only limited performance. This paper develops a novel application of repetitive control (RC) that exploits the capability of learning from experience to enable complete suppression of the tremor. The proposed control structure is applied to suppress tremor at the wrist via FES regulated co-contraction of wrist extensors/flexors. Experimental evaluation is performed using a validated wristrig and results are compared against classical feedback control designs to establish the efficacy of the approach.

Abstract
Tremor is a rapid uncontrollable back-and-forth movement of a body part often seen in patients with neurological conditions such as Multiple Sclerosis (MS) and Parkinson’s disease. This debilitating oscillation can be suppressed by applying functional electrical stimulation (FES) within a closedloop control system. However current implementations use classical control methods and have proved capable of only limited performance. This paper develops a novel application of repetitive control (RC) that exploits the capability of learning from experience to enable complete suppression of the tremor. The proposed control structure is applied to suppress tremor at the wrist via FES regulated co-contraction of wrist extensors/flexors. Experimental evaluation is performed using a validated wristrig and results are compared against classical feedback control designs to establish the efficacy of the approach.
