Performance-based outcome measures are gaining importance in terms of patients' health care. These tests are not specific for any disease or extremity. They are specific tests for walking and getting up from a chair. They evaluate what an individual can do rather than what they perceive the individual can do. Performance measurement tests have a higher level of evidence than just self-reported evaluations.
Time up and go test, two-minute walk test, sit and stand test are the most frequently used tests in the clinic to evaluate functionality. The short duration of the tests and the fact that they do not require equipment provide advantages in the clinical setting.
In the current literature, the validity and reliability of the Time up and go, two-minute walk and sit-up test in elderly prostate cancer patients has not been established. The aim of our study is to investigate the validity and reliability of these tests in elderly prostate cancer patients and to determine their minimum detectable change. Our second aim is to investigate the relationship of these tests we evaluated with the Nottingham Health Profile questionnaire, which evaluates health-related quality of life in elderly cancer patients.
