Devices for controlling tremors

A transcutaneous wearable device (700, 2000) for treating tremors in a patient, the device comprising: a decision unit (100, 702); a first peripheral nerve effector (102, 730, 1500, 1602) comprising at least one transcutaneous stimulation electrode (102, 730, 1500, 1602), wherein the first peripheral nerve effector is configured to place the at least one Transcutaneous stimulation electrode in contact with the patient's skin surface on a first afferent nerve selected from the group consisting of a radial nerve (650, 870), an ulnar nerve (630, 860) and a median nerve (104, 620 , 850), and wherein the at least one transcutaneous stimulation electrode is configured to modulate an afferent path of the first afferent nerve selected; at least one biomechanical sensor (780, 1710, 1730) configured to measure the movement of the patient's limb to characterize one or more characteristics of the tremor, the one or more characteristics of the tremor selected from the group consisting of tremor frequency, period of the tremor and magnitude of tremor; wherein the decision unit comprises a processor (797) and a memory (770) for storing instructions that, when executed by the processor, cause the device to: measure the movement of the patient's limb using a measuring unit (2660 ) to generate motion data; determine one or more of the tremor frequency, tremor period and magnitude of tremor based on an analysis of the movement data; adjust one or more parameters of a first electrical stimulus depending on the characterization of the one or more characteristics of the tremor; and supply the first electrical stimulus transcutaneously to the first afferent nerve selected by the first peripheral nerve effector (102, 730) to say the tremor in the patient's limb reducing synchronicity in a brain network and modifying the dynamics of the neural network of the patient.
