Study Type: Interventional
Study Phase: Not Applicable
SUMMARY

This single-center, randomized, quadruple-blinded, double-crossover comparative efficacy trial will study the effects of unilateral 50% voltage reduction in axial motor dysfunction for patients with Parkinson's disease that develop treatment-resistant postural stability gait dysfunction after bilateral subthalamic nucleus deep brain stimulation surgery.

Eligibility
Participation Requirements
Sex: All
Healthy Volunteers: No
View:

• 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.
