Eligibility Criteria

Inclusion

  • Patients with Parkinson's disease (PD) (previously diagnosed according to the UK brain bank criteria) who develop treatment-resistant postural instability gait dysfunction (PIGD) more than 6 months but less than 5 years after bilateral subthalamic nucleus deep brain stimulation (STN-DBS).
  • Treatment-resistant PIGD will be defined as freezing of gait and UPDRS or MDS-UPDRS PIGD subscales of more than 6 points despite optimization of medications and bilateral STN-DBS programming.

Exclusion

  • Treatment-resistant PIGD less than 6 months or more than 5 years after STN-DBS surgery.
  • PIGD responsive to optimization of medications and/or bilateral STN-DBS programming.
  • Cognitive impairment or psychiatric comorbidities (including substance abuse) that would interfere with the informed consent process, study adherence or outcome assessments.
  • Advanced PD or any other neurological, cardiovascular or musculoskeletal co-morbidities that would preclude or require assistance to complete the 10-meter walking test.
  • Patients not able to comply with 4-week interval evaluations following their potential enrollment due to personal reasons.
  • Serious illness (requiring systemic treatment and/or hospitalization) until subject either completes therapy or is clinically-stable on therapy, in the opinion of the site investigator, for at least 30 days prior to study entry.
  • Inability or unwillingness of subject or legal guardian/representative to give written informed consent.
