Abstract: Objective To explore the method for the objective evaluation of single limb function after injury in forensic medical practice. Methods The score of activities of daily living （ADL） were graded for a single limb function after injury from 47 cases. All cases were simultaneously evaluated using the different methods including Fugl-Meyer motor function assessment （FMA）, weighting, look-up table （LUT）. The correlation were compared between ADL and the other three methods. Results Injured part and the score using the three methods were correlated with ADL score （P<0.05）. The correlation coefficient （｜r｜ value） showed highest using LUT method, and lowest using FMA method. Conclusion The loss function of limb is affected by the injuried parts. The methods of FMA, weighting and LUT show a good accuracy for evaluating the limb function after injury and the correlation presents higher using LUT method.
