This test is indicated for:
- Limited abduction.
- Abnormal scapulo-humeral rhythm.
- A diagnosis of ‘painful arc’ during the abduction movements.
Procedure
- Ask the patient to bilaterally and simultaneously, carry out a maximal active anteflexion movement of 180° (if not possible, attempt passive movement) [Figure 55].
Figure 55
- From this position, instruct the patient to return both arms slowly through the frontal plane (adduction movement) back to the starting position [Figure 56].

- Pay attention to:
- The course of the movements, particularly uniformity and smoothness.
- The occurrence of pain and the possible presence of a ‘painful arc’ or ‘painful drop.’
This test is not possible with a frozen shoulder.
