Malingering is not a diagnosis. It is a behavior for which there are no established diagnostic criteria. Guidelines have been published according to which malingering might be suspected, but those guidelines do not discriminate between patients who are malingering and ones with genuine sources of chronic pain. ⋯ Negative responses do not exclude a genuine complaint of pain, for patients may have a source of pain that is not amenable to testing with diagnostic blocks. Diagnostic blocks have proved particularly useful in the investigation of spinal pain for which the cause is not evident on conventional medical imaging. They can also confirm or refute purported mechanisms of certain clinical features in complex regional pain syndromes.

Comparative Study Clinical Trial
Factors predicting pain reduction in chronic back and neck pain after multimodal treatment.
To determine whether treatment related pain reduction on the short- and long-term is predicted by different baseline variables, and with different accuracy, in patients with chronic low back pain as compared with those with chronic neck pain. ⋯ Patients who reported unchanged or increased pain after multimodal treatment could be predicted with good accuracy, whereas those who reported decreased pain were more difficult to identify. Treatment-related pain alteration in chronic low back pain seems to be predicted by partly different variables than in chronic neck pain.

Comparative Study Clinical Trial
Prognosis of multifactorial outcome in lumbar discectomy: a prospective longitudinal study investigating patients with disc prolapse.
Although previous research has shown that certain medical data and psychosocial factors predict postoperative pain, it remains unclear whether they also contribute to a more distinct outcome measure that is based on classification of self-reported outcome criteria. To assess the prognostic power of somatic, psychologic, and social predictors when evident outcome criteria of surgical treatment are investigated, this study used a prospective longitudinal design examining preoperative factors associated with outcome six months after lumbar discectomy. ⋯ Classification of patients regarding their individual outcome profiles showed that patients responded differently to lumbar disc-surgery. High risk factors for poor outcome of surgery are Laseque-sign and depression.

Malingering--the willful, deliberate, and fraudulent feigning or exaggeration of illness--was originally described as a means of avoiding military service. In present-day clinical practice, malingering may occur in circumstances where the person wishes to avoid legal responsibility or in situations where compensation or some other benefit might be obtained. In law, the term malingering is used in relation to persons to whom military regulations apply; in other situations, malingering is regarded as fraud and may lead to charges of perjury or criminal fraud. ⋯ In this article, we will review the literature on pain and malingering and discuss attempts that have been made to develop methods and guidelines for the detection of malingered pain. There are, however, no valid clinical methods of assessment of possible malingering of pain. In our view, the ultimate issue of the veracity of the plaintiff is for the Court to decide, and epithets such as "malingerer" have no place in reports prepared for legal purposes by health care professionals.
