RESUMEN
Cognitive impairment is common in patients with pain. While symptoms of pain are effectively treated with osteopathic manipulative treatment (OMT), the cognitive complaint is vastly ignored. Pain-induced cognitive dysfunction can be severe and is particularly apparent in working memory and attention. There is good reason to expect cognitive responsiveness to OMT. Previous research has reported the effects of OMT on related psychiatric outcomes, including relief from depression and anxiety, suggesting that OMT may produce more cortical benefits than is currently thought. The rationale to link OMT to cognition comes from the tenets of osteopathic medicine: body unity, homeostasis, and the structure-function relationship. The present article provides background evidence to support the hypothetical link between OMT and cognitive benefits and proposes a physiological mechanism of how OMT could exert its effect on cognition. Research strategies are discussed to test the hypotheses that are generated from the proposed theoretical framework.

The Rey Word Recognition Test potentially represents an underutilized tool for clinicians to use in the detection of suspect effort. The present study examined the predictive accuracy of the test by examining the performance of three groups of participants: (a) 92 noncredible patients (as determined by failed psychometric and behavioral criteria and external motive to feign), (b) 51 general clinical patients with no motive to feign, and (c) 31 learning disabled college students. Results demonstrated gender differences in performance that necessitated separate cutoff scores for men and women. Use of a cutoff score of < or = 7 words correctly recognized identified 80.5% of noncredible female patients while maintaining specificity of > 90%. However, to achieve this level of specificity in male noncredible patients, the cutoff score had to be lowered to < or = 5, with resultant sensitivity of only 62.7%. A combination variable (recognition correct minus false positive errors + number of words recognized from the first 8 words) showed enhanced sensitivity in identifying suspect effort in a subset of the noncredible sample who were claiming cognitive symptoms secondary to traumatic brain injury (i.e., cutoff score of < or = 9 = 81.6% sensitivity with 90% specificity). Results indicate that the Rey Word Recognition Test is an accurate and cost-effective method for the detection of noncredible cognitive performance.
