Abstract
A peripheral nerve stimulator can be used to stimulate a peripheral nerve to treat essential tremor, Parkinson tremor, and other forms of tremor. The peripheral nerve stimulator can be either a noninvasive surface stimulator or an implanted stimulator. Stimulation can be electrical, mechanical, or chemical. Stimulation can be delivered using either an open loop system or a closed loop system with feedback.
Claims20
A method for transcutaneously stimulating peripheral nerves of a user, the method comprising:
- calculating a fraction of a period of a tremor of the user;
- delivering a first stimulus to a first peripheral nerve through a first peripheral nerve effector positioned on a first skin surface of the user to stimulate the first peripheral nerve;
- and
- delivering a second stimulus to a second peripheral nerve through a second peripheral nerve effector positioned on a second skin surface of the user to stimulate the second peripheral nerve;
- wherein the second stimulus is offset in time from the first stimulus by the calculated fraction of the period of the tremor.
A method for transcutaneously stimulating peripheral nerves of a user, the method comprising:
- delivering a first stimulus to a first peripheral nerve through a first peripheral nerve effector positioned on a first portion of a skin surface of the user to stimulate the first peripheral nerve;
- and
- delivering a second stimulus to a second peripheral nerve through a second peripheral nerve effector positioned on a second portion of the skin surface of the user to stimulate the second peripheral nerve,
- wherein the second stimulus is offset in time from the first stimulus by a fraction of a period of a tremor, wherein the fraction is selected from the group consisting of one half of the period of the tremor, one quarter of the period of the tremor, and three fourths of the period of the tremor.
