Purpose
The main goal of this study was to propose and validate a tool to quantify the psychological readiness of athletes to return to sport following traumatic shoulder instability and conservative or surgical management.
Methods
«Knee» was replaced by the term «shoulder» in the Anterior Cruciate Ligament-Return to Sport after Injury scale. This pilot test of the Shoulder Instability-Return to Sport after Injury scale (SIRSI) was performed in a group of athletes who underwent surgery for post-traumatic chronic anterior shoulder instability. The final version was then validated according to the international COSMIN methodology. A retrospective study was performed including all rugby players who had reported an episode of instability between 2012 and 2013. The WOSI and the Walch-Duplay scales were used as reference questionnaires.
Results
Sixty-two patients were included, mean age 26 ± 5.2 years old, 5 women/57 men. Patients were professional or competitive athletes (70.9%) and followed-up for 4.6 ± 1.6 years after the first episode of shoulder instability. Shoulder surgery was performed in 30/62 (48.4%) patients, a mean 1.6 ± 1.2 years after the first episode of instability. The SIRSI was strongly correlated with the reference questionnaires (r = 0.80, p < 10−5). The mean SIRSI score was significantly higher in patients who returned to play rugby (60.9 ± 26.6% vs 38.1 ± 25.6%, p = 0.001). The internal consistency of the scale was high (α = 0.96). Reproducibility of the test–retest was excellent (ρ = 0.93, 95% CI [0.89–0.96], p < 10−5). No ceiling/floor effects were found.
Conclusion
The SIRSI is a valid, reproducible scale that identifies patients who are ready to return to the same sport after an episode of shoulder instability, whether they undergo surgery or not.
