Systems and Methods for Treating Essential Tremor or Restless Leg Syndrome Using Spinal Cord Stimulation

Abstract

A method for treating essential tremor or restless leg syndrome using spinal cord stimulation includes implanting a lead near a spinal cord of a patient. The lead includes a plurality of electrodes disposed on a distal end of the lead and electrically coupled to at least one contact terminal disposed on a proximal end of the lead. Electrical signals are provided from a control module coupled to the lead to stimulate a portion of the spinal cord of the patient using at least one of the electrodes. The electrical signals reduce, alleviate, or eliminate at least one adverse effect of essential tremor or restless leg syndrome.

Benefits of technology

[0011]In one embodiment, a method for treating essential tremor using spinal cord stimulation includes implanting a lead near a spinal cord of a patient. The lead includes a plurality of electrodes disposed on a distal end of the lead and electrically coupled to at least one contact terminal disposed on a proximal end of the lead. Electrical signals are provided from a control module coupled to the lead to stimulate a portion of the spinal cord of the patient using at least one of the electrodes. The electrical signals reduce, alleviate, or eliminate at least one adverse effect of essential tremor.

Problems solved by technology

In general, Parkinsonism impairs motor skills and speech, as well as other functions.

Currently there is no known cure for Parkinsonism.

However, some patients are either unresponsive to medications or detrimentally affected by medications and, instead, undergo brain surgery to reduce, alleviate, or eliminate one or more Parkinsonism-related symptoms.

Currently there is no known cure for essential tremor.

However, some patients are either unresponsive to medications or detrimentally affected by medications and, instead, undergo brain surgery to reduce, alleviate, or eliminate one or more of the symptoms of essential tremor.

However, some patients with restless leg syndrome experience the unpleasant sensation in other body locations in addition to, or instead of, the legs including, for example, one or both feet, one or both thighs, the torso, or one or both arms.

Additionally, some patients may experience an increase in the severity of the unpleasant sensations when sitting or lying down.

Currently there is no known cure for restless leg syndrome.

However, some patients are either unresponsive to, or detrimentally affected by, medications or vitamin or mineral supplements.
