Permanent disability evaluation in terms of dynamic function

This article reviews the concepts of impairment and disability. It is argued that traditional methods of disability assessment based on passive function do not adequately reflect actual loss of function and that it is possible to arrive at a much fairer assessment of residual abilities. The techniques suggested are derived from those already established in the rehabilitation field by the proponents of the GULHEMP System. It is suggested that raditional methods are falling into disrepute because of thier inadequacy and that this reflects on the profession as a whole.
