The purpose of this study was to determine if floor‐to‐waist training weight (FWwt) and volume (FWvol) predict functional outcome following a sports performance based rehabilitation program in workers’ compensation lumbar fusion patients (n=63). PDL was measured at program completion. FWvol was calculated using the best set during the first and last week of the program (Weight X Repetitions). PDL was 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). A one‐way ANOVA was used to analyze relationships between PDL. Fisher’s Exact Test was used for post‐hoc analysis. Pooled comparisons were analyzed by a Student’s t‐test. The level of significance was set at p<0.05. Data are mean±SD. PDL: L=1, LM=1, M=11, MH=25, H=7, VH=20. For statistical analysis the L and LM patients were eliminated. VH had significantly higher FWwt and FWvol at program beginning. FWwt and FWvol increased during the program in all patients (p<0.0001). FWwt at program end varied between all groups (p<0.0001; M=57±16, MH=73±12, H=96±11, VH=125±21 lbs). FWvol at program end varied between groups (p<0.0001). Post‐hoc indicated these differences did not exist between all groups, so M/MH and H/VH groups were pooled (M/MH, n=36; H/VH, n=27). Significant differences existed in FWvol between M/MH and H/VH groups at program completion (p<0.0001; 801±292 vs. 1426±503 lbs/set respectively). These results suggest that FWwt and FWvol and can predict functional outcome following rehabilitation.
