Comparison of Two Treatments for Acute Rotator Cuff Tendinopathy

The primary objective of this study is to compare the short-term effectiveness (2 and 6 weeks following the start of the rehabilitation program), in terms of symptoms and functional limitations, of a rehabilitation program centered on gradual reloading to a rehabilitation program centered on rest and cryotherapy in individuals with acute rotator cuff tendinopathy. The secondary objective is to explore the effects of these programs on shoulder control (acromiohumeral distance), subacromial structures (supraspinatus tendon thickness) and central pain modulation. The hypothesis is that the rehabilitation program centered on gradual reloading will lead to a faster improvement at week 2 and 6 when compared to the program centered on rest and cryotherapy.
