Summary

This trial aims to understand the mechanism and to test whether transcranial direct current stimulation (tDCS) combined with transcranial ultrasound (TUS) (tDCS+TUS) combined with physical therapy (PT) will induce significant therapeutic effects in postural instability in Parkinson's disease (PT) patients. The investigators designed a double-blinded, placebo controlled, randomized study to investigate the effects of 2 weeks of TDCS+TUS on postural instability in PD patients receiving PT. (Followed by biweekly sessions for 2 more weeks in Phase II)

Detailed description

Current treatments for Parkinson's Disease (PD), including pharmacological (levodopa) and surgical (DBS) methods, have limited impact on postural instability. Physical therapy (PT) for PD is becoming increasingly used as a means to induce benefits on patient balance. However, limits in efficacy and consistency still exist. In this study, the investigators will test the effects of TDCS+TUS combined with PT on postural instability of PD patients.

Interventions

Type	Name	Description
DEVICE	Active Comparator: Active tDCS and Active TUS	Device: Transcranial Direct Current Stimulation (tDCS) Subjects will receive 20 minutes of either active or sham tDCS at intensity of 2mA. The anodal electrode will be placed over the primary motor cortex contralateral to the most painful side, and the cathodal electrode will be placed over the contralateral supraorbital area. In the sham group, the tDCS device will not be active for the full 20 minutes. Device: Transcranial Ultrasound (TUS) Subjects will receive 20 minutes of either active or sham TUS. During active stimulation the ultrasound will be active for the full 20 minutes- however, during sham stimulation the ultrasound will not be active for the full 20 minutes.
DEVICE	Sham Comparator: Sham TDCS and Sham TUS	Device: SHAM Comparator Device: transcranial Direct Current Stimulation (tDCS) Subjects will receive 20 minutes of either active or sham tDCS at intensity of 2mA. The anodal electrode will be placed over the primary motor cortex contralateral to the most painful side, and the cathodal electrode will be placed over the contralateral supraorbital area. In the sham group, the tDCS device will not be active for the full 20 minutes. Device: Transcranial Ultrasound (TUS) Subjects will receive 20 minutes of either active or sham TUS. During active stimulation the ultrasound will be active for the full 20 minutes- however, during sham stimulation the ultrasound will not be active for the full 20 minutes.
OTHER	Physical Therapy	All subjects will enroll in a conventional PT balance and gait focused training program, and will receive PT 3x/week over the two weeks of stimulation for 45 minutes following the stimulation sessions when applicable. (And during the biweekly sessions for Phase II)
