This study sought to determine if floor‐to‐waist lift weight (FtW 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). FtW 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 FtW 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=6, MH=12, H=9, VH=12. For analysis the L patient was eliminated. First week FtW wt were: LM 18±3 lbs; MH 29±3 lbs; H 48±6 lbs; VH 50±9 lbs. First week FtW wt was greater in H and VH groups. All groups significantly increased FtW wt . Best OHP wt were: LM 31±3 lbs; MH 62±8 lbs; H 94±8 lbs; VH 107±8 lbs. Post‐hoc analysis indicated best FtW wt increased significantly between each successive PDL group but H and VH did not differ. Linear regression yielded a correlation coefficient of R 2 =0.52 for the relationship between FtW wt and PDL. These results suggest FtW wt can predict PDL following a rehabilitation program.
