Brief Summary

Parkinson Disease (PD) patients experience a variety of motor issues such as walking difficulties, loss of balance, and freezing while walking, which impacts their quality of life. Some symptoms, like freezing of gait (FOG), do not respond to medications typically used to treat PD. Current surgical procedures used to alleviate PD symptoms also do not always improve FOG. Since many traditional therapies have failed for the treatment of FOG, researchers have proposed the use of newer treatments. Recent research in animal models and clinical human data using Spinal Cord Stimulation (SCS) has produced promising results, specifically showing improvement in FOG with the use of SCS in patients with PD. The purpose of this study is to explore the long-term motor and non-motor effects of SCS in PD patients after completing participation on H-49023. The investigators hypothesize that SCS significantly decreases FOG episodes in patients with PD.

  1. 1.Assess the long-term safety, tolerability and preliminary evidence of effectiveness of upper thoracic spinal cord stimulation for freezing of gait in Parkinson's (PD) patients.
  2. 2.Allowing patients to choose between the two SCS programming paradigms based on their motor, nonmotor and quality of life measures in PD patients with freezing of gait.

Interventions

Patients are already implanted with device from the H-49023 study. The SCS implantation technique consists of inserting epidural leads-containing multiple stimulating electrodes (8). Two leads will be implanted percutaneously into the epidural space. The implantable pulse generator (IPG) is a neurostimulation system designed to deliver low-intensity electrical impulses. The system is intended to be used with leads and extensions that are compatible with the system. This neurostimulation system is indicated (FDA approved) as an aid in the management of chronic, intractable pain of the trunk and/or limbs. The intended use in this study is considered experimental.

Also known as: Proclaimâ„¢ Implantable Pulse Generator with leads
