Tiny study tests blood flow cuffs and stepping machine for advanced Parkinson's

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age 18+ 2. People with advanced Parkinson's disease. "Advanced PD" will include signs of progressed disease including orthostatic hypotension and/or motor issues reflective of postural instability and/or mild-moderate bilateral symptoms (confirmed visually in clinic or home by a medical provider such as an MD/PT and/or documented in the medical record. 3.

Commitment to participate in the exercise intervention as outlined 7. Score of ≥21 on the Montreal Cognitive Assessment (MoCA) Exclusion Criteria: 1. History of cardiovascular disease, uncontrolled hypertension (blood pressure ≥140/90 mmHg), deep-vein thrombosis, varicose veins, or rhabdomyolysis which a patient's primary physician determines would preclude them from safe study participation. 2. Ankle branchial index ≤ 0.9 or \> 1.3 3. History of or comorbid conditions spanning cardiovascular, neurological, or orthopedic injuries which may prevent for the safe administration of the intervention (a healthcare provider's clearance or guidance will be obtained in these situations to ensure appropriateness), including current medications. 4.

Absolute contraindications to exercise as per the American College of Sports Medicine (uncontrolled arrhythmias, third-degree heart block, recent electrocardiogram (EKG) changes, unstable angina, acute myocardial infarction, or acute congestive heart failure)
