From: The Oxford Shoulder Instability Score; validation in Dutch and first-time assessment of its smallest detectable change

 WOSI (100–0)a 46.0 (22.3) 45.7 (24.2)b
 SST (0–12)a 8.8 (3.1) 8.8 (3.2)b

 DASH (100–0)a 22.2 (16.7) 22.7 (18.3)b
  1. aRanges reflect most impaired to least impaired function
  2. bNo significant change in shoulder function (WOSI, SST, OSS, DASH) was observed at re-test compared to the baseline assessment
