Abstract: Objective To analyze and compare different methods for assessment of the limbs joints function and to discuss the rationality of the methods. Methods Eight hundred and six cases were collected from the Fujian Minzhong Forensic Appraisal Center from 2007 to 2010. These cases included injuries of large limbs joints with or without peripheral nerve injury. The loss of joint function was calculated according to the simple joint mobility method or the table method introduced in the book “Forensic Clinical Judicial Authentication Practice”. The results of disability evaluation with different methods were analyzed and compared between different joints and injury patterns. Results In 642 cases of simple joint injuries without peripheral nerve injury, the results of disability evaluation based on simple joint mobility were the same as that based on the table. In 118 cases of joint injuries with peripheral nerve injury, all of them could be classified as disability, 33 cases （28.00%） had higher degree based on the table method than based on the simple joint mobility method. While 21 cases （17.80%） did not be evaluated as disabled based on the simple joint mobility method. Conclusion The evaluation for loss of limb function would be easier, more scientific and reasonable by the direct table method than the simple joint mobility method.
