In persons diagnosed with Parkinson’s Disease (PD) (P), how effective is bicycle exercise as physical activity (I) compared to usual care (C) help to improve the stableness or physical health of PD patients (O) when applied to a specific period (T)? The chosen article for the analysis is ‘Parkinson’s disease patients benefit from bicycling’ by Tiihonen et al. 2021. The article’s abstract starts by acknowledging PD patients’ difficulties in containing their conditions. According to Tiihonen et al. (2021), identify and mention that PD patients are adversely compromised and can hardly have stable movement on their own. Hence, the article strives to find out which bicycle exercise would best benefit persons diagnosed with PD. Moreover, the research would also determine which PD-related symptoms or conditions would improve the anticipated bicycle exercise. The abstract introduces the reader to a systematic database literature search, both randomized control trials (RCT) and non-randomized control trials (NRCT), which are the tools used for assessing the effect of bicycle riding on PD patients. Furthermore, the abstract quantifies several sources that were analyzed to arrive at the conclusions that were made after the cohort study. It is presented that out of 202 articles researched, about 22 were found eligible studies with approximately 505 patients suffering from PD condition. Therefore, I think the information contained in this article abstract is adequate to give an overview of the research to its readers. The key issue in this article’s introduction is the goal-directed physical exercise and general physical activities that are in practice to alleviate the challenges faced by PD patients. According to Tiihonen et al. (2021), physical and general activities have been experimentally and scientifically proven to lessen both motor and cognitive symptoms among persons diagnosed with PD. As such, exercise is a complement to standard pharmaceutical and surgical treatment of PD patients. The article further reinstated the need for diversified physical exercise forms for patients suffering from PD conditions to help improve their condition and better their lives. As presented in this article’s introduction, little or resources have been allocated to identifying noble physical activities paramount to improving patients’ needs and well-being. Bicycle riding is, therefore, one such activity that has been proposed by Tiihonen et al. (2021) to help improve PD patients’ conditions as more new forms and technologies are underway concerning therapies for persons struggling with PD conditions. The article states that exercise-based training could enhance functional mobility by utilizing enhanced strength, endurance, balance, and flexibility that support the efficient performance of these groups. Tiihonen et al. (2021), acknowledge that there is no conclusive research that proves exercise as a full remedy for the condition but could be considered as a disease-modifying element that helps in patients’ improvements. In addition, physical activities have been found to have neuroprotective effects on the brain. This research reports that in 2010, some individuals had severe gait freezing as a result of riding bicycles (Tiihonen et al., 2021). Therefore, physical activities have potential benefits f
