Yes. A case study by Dr Vert Mooney* showed that the software features of the MedX® Lumbar Extensor Machine that allow “scrambling” of the visual feedback allowed a very thorough investigation indeed of a potential malingerer. “Consistent submaximal efforts with visual feedback can be achieved by a subject anxious to deceive the tester. However, with reliable equipment and the potential to manipulate the test circumstances, the apparent consistent performance can document a patient’s wilful deception.” Mooney et al., Journal of Workers Compensation 1992 – COPY AVAILABLE * Dr Vert Mooney is Medical Director of the University of California at San Diego Spine & Joint Conditioning Centre and a former Vice President of the American Orthopaedic Association.
