Multidirectional instability (MDI) of the glenohumeral joint is a complex condition involving joint subluxation and/ or dislocation in multiple directions. The condition is often atraumatic and does not typically involve structural pathology.

This high quality RCT sought to compare 2 rehabilitation programs; the Rockwood and the Watson program.

The results of the trial suggest that, whilst both programs demonstrate significant improvement in a variety of measures, the Watson program resulted in the greatest long-term gains.
