RECRUITING

Exploring the Effects of Spinal Cord Stimulation in Parkinson's Disease.

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

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 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 evaluate the effectiveness of spinal cord stimulation (SCS) for the management of freezing of gait (FOG) that does not respond to conventional treatments in subjects with Parkinson's disease (PD). The investigators hypothesize that SCS significantly decreases FOG episodes in patients with PD. 1. Assess the safety, tolerability and preliminary evidence of effectiveness of upper thoracic spinal cord stimulation for freezing of gait in Parkinson's (PD) patients. 2. Explore the effects of two SCS programming paradigms on motor, nonmotor and quality of life measures in PD patients with freezing of gait.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * Males and females between older than 18 years of age.
  2. * Able to provide informed consent
  3. * Diagnosed with idiopathic PD (meeting at least two of the three United Kingdom (UK) Brain Bank criteria for PD, specifically bradykinesia plus resting tremor or rigidity) whose major complaints is levodopa refractory FOG. Levodopa refractoriness will be defined as lack of subjective improvement on FOG episodes as reported by the patient.
  4. * Documented dopaminergic response
  5. * Optimized PD treatment including dopaminergic medications, and/or deep brain stimulation (DBS) therapy
  6. * Presence of at least two self-reported levodopa refractory episodes of FOG per day, not limited to start hesitation
  7. * At least one witnessed freezing event during the screening visit in the 'on' medication state (defined as 45 minutes after a regular dose of Levodopa for the subject being studied)
  1. * Presence of psychosis
  2. * Depression BDI \>14
  3. * Anxiety BAI \>14
  4. * Presence of an active infection, uncontrolled diabetes mellitus, immunosuppression or other medical contraindications to undergoing SCS implantation
  5. * Patients who are currently on anticoagulation treatment or unable to hold off the anticoagulants (including Plavix, Aspirin, Warfarin, etc.) 7 days prior to the SCS procedure.
  6. * Moderate Cognitive Impairment defined by a MoCA \< 23
  7. * Diagnosis of failed back surgery syndrome, Complex Regional Pain Syndrome (CRPS) or intractable low back pain and leg pain.
  8. * Women of childbearing potential will be excluded as from participation due to the limited safety data of thoracic SCS on the fetus.
