Many employers, insurers, and self-insurers suspect workers’ compensation claimants of symptom magnification or malingering.
These terms have been defined as follows:
Symptom Magnification A conscious or unconscious self-destructive, socially-reinforced, behavioral response pattern consisting of reports or displays of symptoms which function to control the life circumstances of the sufferer.
Malingering A conscious and willful fainting or exaggeration of a disease or effect of an injury in order to obtain specific external gain. It is usually motivated by external incentives, such as receiving financial compensation, obtaining drugs, or avoiding work or other responsibilities.
The physicians performing Independent Medical Evaluations in orthopedic cases need to correlate the examinees’ subjective complaints with his/her objective findings.
A common method of testing for exaggeration of faking is the use of Waddell’s signs.
These signs include:
Positive Waddell’s sign for tenderness- if there is deep tenderness over a wide area, that is a positive sign.
Stimulation – downward pressure on the head causes low back pain is a positive sign. The examiner holding the shoulders and hips in the same plane and rotating patient, resulting in pain is a positive sign.
Distraction – straight leg raise causes pain when formally tested, but straightening the leg with the hip flex 90 degrees to check Babinski sign does not cause pain, is a positive sign.
Regional – if there is weakness in multiple muscles not enervated by the same root sensation, such as a “glove and stocking” loss of sensation, this is a positive sign.
Overreaction – if there is an excessive show of emotion, this is a positive sign.
Test to detect false paresis (weakness or loss of voluntary movement) is the “arm drop” test. The examiner holds the paretic hand above the patient’s face and drops it, if that hand misses the patient’s face on the way down, the paresis is non-organic.
