WRIGHTS TEST FOR THORACIC OUTLET SYNDROME (TOS) - SUBCORACOID TUNNEL AND COSTOCLAVICULAR SPACE The Wright's test is a test for thoracic outlet syndrome (TOS) and consits of two phases: In the first phase you are putting stress on the subcoracoid tunnel under the tendon of the pectoralis minor. In the second step, you are hyperabducting the arm and thus stressing the costoclavicular space. Both sites are interfaces where the brachial plexus might get compressed. | Physiotutors

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
