Within this critical appraisal, the background information of a study regarding hydrotherapy versus land-based methods for management of osteoarthritis (OA) knee pain, the strengths and weaknesses of each section, and further discussion of the relevance and application of this study are all addressed. The first section addressed in this appraisal is the methods that pertains to where and how the article was found, as well as why this article was chosen in order to address my specific clinical question. The appraisal then goes on to discuss both the strengths and weakness of each section presented in the article. Some of the biggest strengths include the fact that it was a controlled randomized test, there was one unbiased investigator performing evaluations, a detailed description of the intervention plan was provided, and all outcome measures were addressed. While there were not many large weaknesses to this study's article, some of the ones mentioned in this appraisal include the lack of data collection details and OA statistics or more detailed information, and the fact that participants knew their group placements. The appraisal then goes on to discuss the importance of knowing the results of this study and how it addresses the presented clinical question, potential risks and benefits of implementation, and why I, as a student physical therapist, would consider implementing such techniques in my future care of OA patients.
