After every physical therapy session, the therapist provides the patient with a series of home exercises to complete before the next appointment. Ultimately, it is up to the patient to decide whether or not to follow through. Research conducted during the past few decades has highlighted an alarming degree of patient non-compliance. According to a study by the National Institute of Health in 2005, as many as 40% of physical therapy patients fail to comply with treatment plans. Additionally, when these plans require lifestyle changes or are very complex, non-compliance can be as high as 70%. This project aims to analyze the long term implications of adherence v. non-adherence on the patient's recovery. Now, how exactly are we to measure patient compliance? Self-reported surveys or charts? Not every patient will be so willing to admit he/she has not completed their recommended exercise routine. Therefore, this project goes beyond the basic questionnaire that will be administered. While observing physical therapy sessions, I will record and analyze patients' muscle tension after being manually stretched out by a physical therapist. This will help determine the degree to which the patient performed the home exercises. Through my research, I hope to determine how accurately patients tend to report compliance and help eliminate possible treatment barriers.
