Systems and methods for treating essential tremor or restless leg syndrome using spinal cord stimulation

1. A method for treating essential tremor or Parkinsonism using spinal cord stimulation, the method comprising:

implanting a lead in an epidural space of a spinal cord of a patient at a position adjacent to one or more segments of the spinal cord, wherein each of the one or more segments are lumbar or sacral segments or thoracic segments in a range from T7 to T12, the lead comprising 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; and

providing electrical signals from a control module coupled to the lead to stimulate the one or more segments of the spinal cord of the patient adjacent to which the lead is implanted using at least one of the electrodes, wherein the electrical signals reduce, alleviate, or eliminate at least one adverse effect of essential tremor or Parkinsonism.

2. The method of claim 1 , wherein implanting the lead comprises implanting the lead such that at least one of the electrodes is in proximity to a segment of the spinal cord to which at least one nerve attaches, the at least one nerve also attaching to at least one skeletal muscle at a portion of the patient's body that is adversely affected by essential tremor or Parkinsonism.

3. The method of claim 1 , wherein implanting the lead comprises implanting the lead near a portion of the spinal cord with nerve roots extending to a lower extremity.

4. The method of claim 1 , wherein the electrical signals reduce, alleviate, or eliminate tremors associated with essential tremor or bradykinesia, shuffling gate, stooping posture, or tremors associated with Parkinsonism.

5. The method of claim 3 , wherein the electrical signals reduce, alleviate, or eliminate pain associated with essential tremor or Parkinsonism.

6. The method of claim 3 , wherein implanting the lead comprises implanting at least one of a percutaneous lead, a paddle lead, or a cuff lead.

7. The method of claim 3 , further comprising adjusting stimulation parameters of the electrical signals to reduce, alleviate, or eliminate the at least one adverse effect of essential tremor or Parkinsonism.

8. A method for treating restless leg syndrome using spinal cord stimulation, the method comprising:

implanting a lead in an epidural space of a spinal cord of a patient at a position adjacent to one or more segments of the spinal cord, wherein each of the one or more segments are lumbar or sacral segments or thoracic segments in a range from T7 to T12, the lead comprising 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; and

providing electrical signals from a control module coupled to the lead to stimulate the one or more segments of the spinal cord of the patient adjacent to which the lead is implanted using at least one of the electrodes, wherein the electrical signals reduce, alleviate, or eliminate at least one adverse effect of restless leg syndrome.

9. The method of claim 8 , wherein implanting the lead comprises implanting the lead such that at least one of the electrodes is in proximity to a segment of the spinal cord to which at least one nerve attaches, the at least one nerve also attaching to at least one skeletal muscle at a portion of the patient's body that is adversely affected by restless leg syndrome.

10. The method of claim 8 , wherein implanting the lead comprises implanting the lead near a portion of the spinal cord with nerve roots extending to a lower extremity.

11. The method of claim 8 , wherein the electrical signals reduce, alleviate, or eliminate unpleasant sensations associated with restless leg syndrome.

12. The method of claim 8 , wherein the electrical signals reduce, alleviate, or eliminate pain associated with restless leg syndrome.

13. The method of claim 8 , wherein implanting the lead comprises implanting at least one of a percutaneous lead, a paddle lead, or a cuff lead.

14. The method of claim 8 , further comprising adjusting stimulation parameters of the electrical signals to reduce, alleviate, or eliminate the at least one adverse effect of restless leg syndrome.
