Tremor is the most common movement disorder, and one of the major causes of functional disability. In spite of the existence of various treatments, tremor is not managed effectively in a large number of patients, which make it a major cause of loss of quality of life. Here we present a novel strategy for tremor suppression through neurostimulation that replicates an adaptive notch-filter at the frequency of the tremor. The controller, which adapts the neurostimulation to the ongoing amplitude, frequency and phase of the tremor, is implemented in a wearable neuroprosthesis for tremor management. Experimental results in one patient with severe essential tremor illustrate the interest of the approach.
