Wright's test for thoracic outlet syndrome (TOS) The Wright’s test is designed to decrease the retropectoralis minor space in the first step, while the second part of the test implicates the costoclavicular interval. Unclear descriptions in the performance of the Wright’s test in the study of Gillard et al. in 2001 prohibit any statement about the accuracy of this test. For this reason, the clinical value in practice is questionable. A positive result is a decrease in the radial pulse and/or rep

Clarke's Sign / Patellar Grind Test for Patellofemoral Pain The Clarke's Sign is a common test that is used in the diagnosis of patellofemoral pain syndrome (PFPS) as it is reasoned to stress the patellar cartilage.

For this reason, Clarke's Sign does not seem to be able to add much value to the diagnosis of PFPS. | Physiotuto
