the test is performed in the sitting and then in a the supine positions
the test is performed in 2steps
- first step:
- head forward,while the arm is passively brought into abduction and external rotation to 90 without tilting the head.
- The elbow is flexed no more than 45. The arm is then held for 1 min
- the tester measure radial pulse and monitor patient symptoms onset
2. seconed step:
- The tester monitors the patient’s symptom onset and the quality of the radial pulse.
- The test is repeated with extremity in hyperabduction (end range of abduction) .
A decrease in the radial pulse and/or reproduction of the patient’s symptoms
The pulse disappearance indicates a positive test result for thoracic outlet syndrome
- Given the numerous possible causes and symptoms associated with TOS, no single test can unequivocally establish the presence or absence of the condition, particularly where sTOS is concerned (Roos, 1982; Lindgren, 1997).
- The classic provocation tests have been reported to be unreliable and frequently positive (up to 90%) for pulse obliteration in healthy patients (Hachulla et al., 1990; Urschel et al., 1994; Rayan and Jensen, 1995; Nannapaneni and Marks, 2003).
