Description of intervention(s) / exposure
Cross-sectional observation trial comparing the ultrasound measurement of humeral head position / translation of unstable and stable shoulders.

The participant will be standing with the shoulder exposed. The ultrasound transucer will be placed on the shoulder while participants hold 2kg in the hand, lift their arm up 60 degrees to the side, push out to the side against a 2kg cable weight, and rotate their arm to the side. They will be required to raise and lower their arm between repeat measures to briefly assess assessor reliability.

This process will take up to 20 minutes.

Ultrasound measures will be completed by a physiotherapist (DV).

No exercise/warm-up will be required prior or during the ultrasound assessment.

Summary
Brief summary
This is the first component of a masters project that is investigating humeral head position and translation in unstable shoulders. In this observational study, we aim to measure the differences in humeral head position and/or translation between unstable and stable shoulders. We hypothesise that there will be detectable differences between stable and unstable shoulders as measured by ultrasound. This may then inform treatment strategies that aim to address the pathological humeral head position / translation.
