Purpose[edit | edit source]
The athletic shoulder (ASH) test is used to assess and monitor the shoulder isometric strength of athletes during recovery[1]. It is a novel test developed by Ashworth et al. (2018) that is focused on rugby players who are at risk of shoulder injuries when performing long lever arm tackles.
Technique[1][edit | edit source]
Position: Prone on the floor with the forehead resting on a 4cm foam block and the hand placed on a vertical axis platform.
Procedure:
Subject will push down from the shoulder in three consecutive test positions maximally for 3 seconds:
- I-test: Shoulder positioned in full abduction (180°), forearm in pronation and elbow in full extension. Contralateral arm at the side.
- Y-test: Shoulder positioned at 135°, forearm in pronation and elbow in full extension. Contralateral arm placed behind the back
- T-test: Shoulder positioned at 90°, forearm in pronation and elbow in full extension. Contralateral arm placed behind the back
Evidence[edit | edit source]
The test demonstrates excellent reliability but further studies are needed to assess its sensitivity[1]
- Interday reliability in all test positions (ICC 0.94–0.98)
- Absolute reliability (SEM 4.8–10.8)
- Interday measurement error was below 10% in all test positions (CV 5.0–9.9) except for non-dominant arm I-position (CV 11.3%)"
Resources[edit | edit source]
Using a force platform is considered the gold standard in assessing isometric force[3]. However, due to its cost and impracticality, other devices are studied as potential alternatives[4][5]. The Modified-Athletic Shoulder Test (M-AST) is a promising alternative, utilizing handheld dynamometer for easier implementation of the test. A strong concordance was found between ASH Test and M-AST values (ICC = 0.86–0.97; p > 0.05) in all the positions[5].
