Abstract
Hand impairment is a common and serious occupational injury among workers because it can affect the outcome to return to work (RTW) and even cause permanent dysfunction. The hand measures can directly describe the primary hand function and limitation. This study investigated the correlation of RTW and the overall hand impairment measures in the workers with traumatic hand injury. Ninety-six subjects with occupational hand injury were recruited in this study to answer the RTW questionnaire and received the hand evaluation and motion analysis for their affected hands. RTW outcomes assessed whether the subjects successfully returned to work, either from a job change or salary reduction, and the length of the time it took for them to return to work (TRTW). The hand impairment measures included the hand impairment ratio, total active motion loss, motion area loss, grasp power loss, lateral-pinch power loss, and palmar-pinch power loss. A stepwise regression indicated that grasp power loss was a significant predictor for the length of TRTW. The motion area loss was firstly adopted to show statistically significance with RTW outcomes. Besides, the hand impairment ratio was also found to have mild positive correlation with TRTW significantly. This study presented the subtle correlation of RTW outcomes and hand impairment measures. Both the strength loss and the motion area loss of the hand showed the significant correlation with RTW outcomes. The findings can point to some practical focuses in occupational rehabilitation for the workers with hand trauma.
