Parkinson's disease has a significant impact on a person's ability to control daily movements, affecting quality of life and independence. (Sage, Johnston and Almeida, 2011). Parkinson's disease is chronic, progressive and still incurable (Hirsch, Iyer, Englert, & Sanjak, 2011). Drug therapy remains the main treatment for Parkinson's disease. However, it causes complications such as motor fluctuations, dyskinesias and wear and tear (Sage, Johnston and Almeida, 2011). This has prompted researchers to discover alternative therapies such as exercise, which could potentially improve the suffering of the individual with Parkinson's disease, as exercise is generally associated with cardiovascular and musculoskeletal benefits. (Sage, Johnston and Almeida, 2011). Based on two journal articles written on this topic, this article will analyze how exercise has the potential to improve the suffering of individuals 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” by Hirsch, MA, Iyer, SS, Englert, D. & Sanjak,M., was published in 2011 by Future Medicine Limited . The purpose of this article was to present a new approach to providing physical activity (exercise) to clients with Parkinson's disease. The authors describe community-based participatory research (CBPR) in which people with Parkinson's disease participated. Patients were active as co-researchers in the development of community-based research programs (Hirsch, Iyer, Englert, & Sanjak, 2011). This was followed by further discussion on providing some examples of community exercise programs and suggestions (Hirsch, Iyer,...... middle of document...... exercise intervention. Thus, the only addition to a participant's normal routine was their assigned exercise program” (Sage, Johnston, & Almeida, 2011). diagnosed participants for the research instead of using all people with different types of Parkinson's disease, as this might not yield the same results as it is really difficult to proceed with so much information; According to Hirsch et al (2011), the study was community based and engaged people with Parkinson's disease and patients as co-investigators, very appropriate as the research was carried out on the. entire community without any participant having been diagnosed with Parkinson's disease. The results of this study were based on the entire community and were not limited to participants diagnosed for the exercise research group..
