This study sought to determine if overhead press weight (OHP wt ) could predict functional outcome (Physical Demand Level; PDL) following a sports performance based rehabilitation program in workers' compensation rotator cuff repair patients (n=40). OHP wt was measured weekly during rehabilitation and determined by the best set of 8–12 repetitions. PDL was measured at program completion (KEY Method) and classified by occasional occupational lifting requirements: LIGHT (L; 20lbs), LIGHT‐MEDIUM (LM; 35lbs), MEDIUM (M; 50 lbs), MEDIUM‐HEAVY (MH; 75lbs), HEAVY (H; 100lbs), VERY HEAVY (VH; >100lbs). ANOVA analyzed relationships between PDL and OHP wt . Fisher's Exact Test was used post‐hoc. Paired t‐test assessed first/best week change. Alpha=0.05. Data are mean±SEM. PDLs were L=1, LM=5, MH=13, H=9, VH=12. For analysis the L patient was eliminated. First week OHP wt were: LM 9±3 lbs; MH 22±2 lbs; H 24±3 lbs; VH 32±5 lbs. First week OHP wt did not differ between groups. MH, H, and VH groups significantly increased OHP wt . Best OHP wt were: LM 18±4 lbs; MH 33±4 lbs; H 44±4 lbs; VH 57±6 lbs. Post‐hoc analysis indicated best OHP wt was significantly higher in the VH group. Linear regression yielded a correlation coefficient of R 2 =0.44 for the relationship between OHP wt and PDL. These results suggest OHP wt can predict PDL following a rehabilitation program.
