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 Type : Interventional  (Clinical Trial)
Actual Enrollment : 12 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
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
Masking: Triple (Participant, Investigator, Outcomes Assessor)
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
Primary Purpose: Treatment
Official Title: A Forced Cycling Exercise Program in Individuals With Parkinson's Disease: Can it Improve Gait Parameters?
Actual Study Start Date : June 2014
Actual Primary Completion Date : June 2019

Arm Intervention/treatment
Active Comparator: Forced exercise cycling
Cycling exercise at approximately 90 rpm
Other: Cycling at Forced rate
Active Comparator: Self-selected pace cycling
Cycling at self selected rate, with same aerobic level as forced cycling group
Other: Cycling at self-selected rate

Primary Outcome Measures :
  1. 6-minute walk test [ Time Frame: 8 weeks ]
    Distance walked in 6 minutes

Secondary Outcome Measures :
  1. Stride length [ Time Frame: 8 weeks ]
    Length of stride in meters as measured by the GAITrite

  2. Step Width [ Time Frame: 8 weeks ]
    Width of step in meters as measured by the GAITrite

  3. Step variability [ Time Frame: 8 weeks ]
    Standard deviation of step as measure in meters by the Gaitrite system

  4. 10 meter walk test [ Time Frame: 8 weeks ]
    Time in seconds for the subject to walk 10 meters

  5. miniBESTest (Balance Evaluation Systems Test) [ Time Frame: 8 weeks ]
    Subject is scored as the 14 activities on this scale are performed, and a summary score is derived.

Other Outcome Measures:
  1. Steps per day [ Time Frame: Over 8 week trial and for 2 months post intervention ]
    Subjects steps per day will be measured with a Garmin wrist step counter
