Execution:
- Patient is in sitting position
- Position 1: Patient’s shoulder is in 90° of abduction, external rotation and no more than 45° of elbow flexion and the examiner palpates the radial pulse
- Position 2: Patient’s shoulder is in full abduction and external rotation and the examiner palpates the radial pulse
- Both positions are held for 1 minute
Positive Outcome: Reproduction of patient’s familiar symptoms or abolition of the radial pulse
| Study | Reliability | Sn | Sp | LR+ | LR- |
| Gillard et al. (2001): pulse abolition | NA | 70 | 53 | 1.49 | 0.57 |
| Gillard et al. (2001): symptom reproduction | NA | 90 | 29 | 1.27 | 0.34 |
| Comment: The test is designed to narrow the subcoracoid tunnel (position 1), while position 2 stresses the brachial plexus in the costoclavicular space | |||||
