            Examination type | 
                
				
				Neurological, Vascular integrity | 
              
              
                | 
            
            Patient & Body Segment Positioning | 
                
				The patient 
				is sitting or standing with both elbows bent to 900 
				of flexion and both shoulders in 900 of abduction and 
				with full external rotation. | 
              
              
                | 
            Examiner Position | 
                
				Standing or 
				sitting in front of the patient to observe. | 
              
              
                | 
            Tissues 
            Being Tested | 
                
				Subclavian 
				and axillary arteries and the brachial plexus | 
              
              
                | 
            Performing the Test | 
                
				The patient 
				should rapidly open and close both hands while in the position 
				described above for 3 minutes. | 
              
              
                | 
            
            Positive Test | 
                
				The 
				inability to maintain the test position, diminished motor 
				function of the hands, and /or loss of sensation in the upper 
				extremities are positive signs/symptoms.  | 
              
              
                | 
            
            Interpretation | 
                
				A positive 
				test is indicative of thoracic outlet syndrome, secondary to 
				neurovascular compromise.  This test evaluates both neural and 
				vascular structures and is considered to be the most accurate 
				clinical test for assessing thoracic outlet syndrome. |

            Common errors in 
            performing exam | 
                
				Do not test 
				for more than 3 minutes.  Discontinue the test if positive signs 
				or symptoms are observed before the 3 minutes are up. | 
              
              
                | 
            
            Factors possibly 
            resulting in misinterpretation | 
                
				Underlying 
				shoulder or elbow pathology may make this test difficult to 
				perform.  The hands may become cold, but this is not necessarily 
				due to injury. |
