RESUMEN
Objective To explore themethod for the objective evaluation of single lim b function after in-jury in forensic m edical practice. Methods The score of activities of daily living (ADL ) w ere graded for a single lim b function after injury from 47 cases.Allcases w ere sim ultaneously evaluated using the differentmethods including Fugl-M eyer m otor function assessm ent (FM A ), w eighting, look-up table (LUT). The correlation w ere com pared betw een ADL and the other threemethods. Results Injured part and the score using the threemethods w ere correlated w ith ADL score (P<0.05). The correlation coeffi-cient (|r| value) show ed highest using LUTmethod, and low est using FM Amethod. Conclusion The loss function of lim b is affected by the injuried parts. Themethods of FM A , w eighting and LUTshow a good accuracy for evaluating the lim b function after injury and the correlation presents higher using LUTmethod.
