Execution:
- The patient is in standing position and the examiner palpates the patient’s posterior superior iliac spines (PSIS)
- Then, the patient is asked to bent forward towards the midline, while the examiner palpates the movement of the PSIS
Positive Outcome: The test is positive if one PSIS moves earlier (before 60° of forward flexion) and thus travels higher upward than the other due to hypomobility on that side
| Study | Reliability | Sn | Sp | LR+ | LR- |
| Levangie et al. (1999) | NA | 17 | 79 | 0.81 | 1.05 |
| Riddle et al. (2002) | Inter к= 0.32 | NA | NA | NA | NA |
| Comment: Levangie et al. Compared the associtation of a positive test result with the presence of static innominate torsion. Riddle et al. Show that this test has a low reliability. | |||||
