Research Progress on Function Evaluation Standard and Method of Lower Extremity Impairment

The lower extremity impairment can be caused by illness, accident, work-related injury, traffic accident and fighting, etc. The injuries of lower extremity joint, nerve, muscle and tendon may lead to lower extremity dysfunction. So far, there is no unified standard for international and domestic function evaluation of lower extremity impairment, the evaluation standards in the same field are also different, and function evaluation of lower extremity impairment has no complete research system. However, the degree of lower extremity impairment has great influence on personal damage compensation. Therefore, the function evaluation of lower extremity impairment often becomes a dispute issue in forensic medicine identification. This article summarizes the function evaluation standards, methods and status quo of lower extremity impairment, so as to provide a new insight into the research on standardization of lower extremity impairment.
