Development of Korean Academy of Medical Sciences Guideline Rating the Physical Impairment: Lower Extremities

Lower Extremities Committee of Korean Academy of Medical Sciences Guideline for Impairment Rating develops new guidelines which are based on McBride method, American Medical Association Guides, Disability evaluation by The Korean Orthopaedic Association, The Korean Neurosurgery Society, and Korean Academy of Rehabilitation Medicine. The committee analyzed and discussed to create an ideal method practical in Korea. Our committee endeavors to develop new methods which are easy to use, but are suitable for professional use and also independent from the examinee's intentions. The lower extremities are evaluated on the basis of anatomic change, functional change, and diagnosis based evaluation. Nine methods are used to assess the lower extremities. Anatomic assessment includes leg length discrepancy, ankylosis, amputation, skin loss, peripheral nerve injury, and vascular disease. In functional assessment, range of motion and muscle strength are included. Diagnosis-based assessments are used to evaluate impairment caused by specific fractures, deformities, ligament instability, meniscectomies, post-traumatic arthritis, fusion of the foot, and lower extremity joint replacements.
