Parkinson's disease has a dramatic impact on the ability to control daily movements, thus affecting quality of life and independence. (Sage, Johnston, & Almeida, 2011). Parkinson's disease is chronic, progressive, and still incurable (Hirsch, Iyer, Englert, & Sanjak, 2011). Pharmacotherapy continues to be the primary treatment for Parkinson's disease. However, it causes complications such as motor fluctuations, dyskinesia, and attrition (Sage, Johnston, & Almeida,2011). This has prompted researchers to discover alternative therapies such as exercise, which could potentially improve an individual's suffering from Parkinson's disease, as exercise is commonly associated with cardiovascular and musculoskeletal benefits. (Sage, Johnston, & Almeida, 2011). Based on two journal articles written on this topic, this article will explore how exercise has the potential to improve the suffering of the individual with Parkinson's disease. It will also compare the similarities and differences of the research. The first article, “Promoting Exercise in Parkinson's Disease through Community-Based Participatory Research,” written by Hirsch, M.A., Iyer, S.S., Englert, D. & Sanjak,M., was published in 2011 by Future Medicines Limited. The purpose of this article was to introduce a new approach to providing physical activity (exercise) for clients with Parkinson's disease. The authors describe community-based participatory research (CBPR) involving people with Parkinson's disease. Patients engaged as co-researchers in the development of community-based research programs (Hirsch, Iyer, Englert, & Sanjak, 2011). This was followed by further discussion aimed at providing some examples of community exercise programs and suggestions (Hirsch, Iyer,...... middle of paper... exercise intervention. Therefore, the only addition to the normal a participant's routine was the exercise program assigned to them." (Sage, Johnston, & Almeida, 2011). Therefore this method used was appropriate as they only used diagnosed participants for the research instead of using all people with different types of Parkinson's disease as it may not produce the same results as it is really difficult to proceed with so much information while according to Hirsch et al (2011), the study was community based and involved people with Parkinson's disease and the patients they supported; as co-investigators very appropriate as the research was conducted on the entire community without any participant having been diagnosed with Parkinson's disease. The findings of this study were based on the entire community and were not limited to participants diagnosed with Parkinson's disease for the exercise research group.
