Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this trial is to compare the effect of two different exercise programs on neuro-physiological, motor, functional, and quality-of-life issues in individuals with Parkinson's disease to determine which program is most beneficial.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Parkinson's disease (PD) negatively affects the quality of life for a million individuals in the United States. While medication and surgery are the most effective treatments for PD, physicians and people with PD often delay using these treatments because of their considerable adverse side effects. Until a cure for PD is discovered, there is a compelling need to develop interventions that provide relief of symptoms without causing negative side effects.

Recent research suggests that exercise may provide symptom relief in some characteristics of PD. While various exercise interventions appear to effectively improve motor, functional, and quality-of-life issues, the research is mixed regarding the nature, extent and duration of these improvements. Understanding how multiple characteristics of PD change and whether they can be modified by different exercise programs is essential to determining if an exercise program is clinically effective for PD.

This study is designed to compare the initial (six months), and then long-term (2 years) effect that 2 different exercise programs (progressive resistance program or flexibility program) have on neuro-physiological, motor, functional, and quality-of-life issues in individuals with Parkinson's disease. The goal is to determine which program is most beneficial. Results from this study will be used to determine which exercise program produces the most beneficial effects on neuro-physiological, motor, functional and quality-of-life measures.

NOTE: Recruitment for Parkinson's disease participants is now closed.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Progressive resistance training

Subjects will perform between 60 and 90 minutes of progressive resistance training two times a week for two years at a local gym. These sessions will be supervised by a personal trainer two times a week for the first six months of training and then once a week for the remaining 18 months of training.

Group Type ACTIVE_COMPARATOR

Progressive resistance training

Intervention Type BEHAVIORAL

Exercise twice a week for 2 years doing either progressive resistance training. The The PRE program consisted of 11 strengthening exercises: chest press, latissimus pull downs, reverse flys, double leg press, hip extension, shoulder press, biceps curl, rotary calf (ankle plantar flexion), triceps extension, seated quadriceps extension and back extension.

Modified Fitness Counts

Subjects will perform between 60 and 90 minutes of modified Fitness Counts two times a week for two years at a local gym. These sessions will be supervised by a personal trainer two times a week for the first six months of training and then once a week for the remaining 18 months of training.

Group Type ACTIVE_COMPARATOR

Modified Fitness Counts

Intervention Type BEHAVIORAL

The modified Fitness Counts program was taken from Chapters 2 and 3 of the Parkinson's disease: Fitness Counts booklet and focused on non-progressive stretching, strengthening and balance exercises.
