Brief summary
The purpose of this study is to assess the effectiveness of a forced exercise aerobic exercise program, utilizing a cycling activity, on specific gait parameters and balance in individuals with Parkinson's Disease (PD). Design: pilot, feasibility, randomized control, evaluator blinded. Subjects: Twenty four patients with idiopathic PD Hoehn and Yahr (H&Y) stage II or III. Intervention: Participants randomly assigned to one of two exercise groups, forced exercise or self selected exercise, on cycling machine three times a week for 8 weeks. Both groups to exercise at same aerobic intensity level to keep heart rate at 60-80% heart rate max. Outcomes: Gait parameters of step length, width, and variability as measured by the GAITRite; 6 Minute Walk Test; mini-BESTest (balance testing); exercise tolerance via Patient Reported Outcomes Measurement Information System (PROMIS) scale.

Study design
Masking description
Participants and those performing outcome assessments were not aware of group allotment, nor was the PI. The therapists supervising the exercise interventions were aware of the group allotment
Intervention model description
Subjects were randomized to a delay start or immediate start group and then for the cycling, the intervention was randomized to : forced pace (80-90 revolutions per minute with equals 15 miles per hour cycling rate or self-selected with both groups working at similar aerobic levels
Eligibility
Inclusion criteria
* Idiopathic Parkinson's Disease * Hoehn and Yahr Stages II - III. * Ages 30-80 years * Medical Clearance * Ability to understand and the willingness to sign a written informed consent.
Exclusion criteria
* MOCA: (Montreal Cognition Scale) : rating of less than 24, indicative of cognitive dysfunction * Changes in Parkinson's medications within the two weeks prior to starting the study * Anticipated change in Parkinson Disease medications during the course of the study * Uncontrolled orthostasis * Symptomatic coronary artery disease * Fracture of lower limb within 6 months prior to study onset or significant lower limb orthopedic diagnosis that would limit cycling * Other significant neurologic diagnoses including multiple sclerosis or vestibular disease * Acute illness * Physical therapy within the month prior to study entry * Subjects already participating in a forced exercise or high intensity exercise program * Any medical condition that the physician investigator determined would compromise safety.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 6-minute walk test | 8 weeks | Distance walked in 6 minutes |
Secondary
