• Participant is in a very advanced stage of Parkinson's disease defined as: (i) Stage 5 as classified by the Hoehn and Yahr scale on medication and DBS (non-ambulatory) or (ii) participant requires an assistive device to perform the TBC OFF-meds /ON-DBS at the time of enrollment.
• Participant has a condition that makes walking difficult or could interfere with the study procedures or confound the evaluation of the study data, including musculoskeletal issues, peripheral neuropathies, hip/knee prostheses, or any visual or anatomical abnormality that affects their walking.
• Participant has disabling dyskinesias.
