            Examination type | 
                
				
				Neurological, Vascular integrity | 
              
              
                | 
            
            Patient & Body Segment Positioning | 
                
				The subject 
				should be seated and relaxed. | 
              
              
                | 
            Examiner Position | 
                
				The examiner 
				stands behind the athlete and palpates the radial pulse on the 
				involved side throughout the test. | 
              
              
                | 
            Tissues 
            Being Tested | 
                
				Brachial 
				plexus (medial trunk, C8-T1) and the subclavian artery and vein | 
              
              
                | 
            Performing the Test | 
                
				The examiner 
				continuously palpates the radial pulse on the side being tested 
				while abducting the arm to 45 degrees, extending the shoulder to 
				45 degrees, externally rotating the humerus, and applying a 
				downward traction to the arm. The patient is then asked to fully 
				turn his/her head away from the side being tested and extend the 
				cervical spine.  | 
              
              
                | 
            
            Positive Test | 
                
				
				Disappearance or decreasing of the radial pulse  | 
              
              
                | 
            
            Interpretation | 
                
				Indicates 
				thoracic outlet syndrome.  The presence of a cervical rib 
				compressing the neurovascular bundle may be responsible. | 
              
              
                | 
            
            Common errors in 
            performing exam | 
                
				Palpate the 
				radial pulse throughout the entire test, not just before and 
				after positioning the patient. | 
              
              
                | 
            
            Factors possibly 
            resulting in misinterpretation | 
                
				Radial pulse 
				disappearance is not by itself specific, but loss of pulse with 
				reproduction of symptoms is a positive sign for thoracic outlet 
				syndrome. |
