The present study was undertaken to compare emotional distress and functional ability between two common pain populations--acute jaw pain (JAW; n = 135) and acute low back pain (LB; n = 71). Patient groups were evaluated and compared on a variety of biopsychosocial measures, including the Beck Depression Inventory (BDI), Multidimensional Pain Inventory (MPI), Characteristic Pain Intensity (CPI), and Ways of Coping Questionnaire. Specific diagnoses were assessed using the Structured Clinical Interview of the Diagnostic and Statistical Manual (DSM-IV)--I and II, and rates of Axis I and II diagnoses in these groups were further compared to base rates in the general population. Additionally, medication usage was evaluated to determine group differences. Results revealed that JAW patients had lower BDI and CPI scores, as well as a higher level of functioning on the Global Assessment of Functioning assessed by the DSM-IV. Both acute pain groups also had significantly more Axis I and II disorders than the general population. Additionally, it was found that the JAW group used more benzodiazepines, while the LB group used more schedule II narcotics. A logistic regression model created from these variables found a six-factor model, composed of the CPI, MPI coping style anomalous, Ways of Coping problem-solving, Global Assessment of Functioning, anxiety disorders, and Cluster C personality disorder diagnoses, that differentiated the JAW from the LB group. Overall, these findings suggest that the differences identified between these two groups should be considered in developing tailored treatments for individuals with acute low back and jaw pain.

Musculoskeletal pain changes how people move. Although experimental pain is associated with increases in the variability of motor output, it is not clear whether motor-evoked pain in clinical conditions is also associated with increases in variability. In the current study, we measured jaw force production during a visually guided force paradigm in which individuals with chronic jaw pain and control subjects produced force at 2% of their maximum voluntary contraction (low target force level) and at 15% of their maximum voluntary contraction (high target force level). State measures of pain were collected before and after each trial. Trait measures of pain intensity and pain interference, self-report measures of jaw function, and measures of depression, anxiety, and fatigue were also collected. We showed that the chronic jaw pain group exhibited greater force variability compared with controls irrespective of the force level, whereas the accuracy of force production did not differ between groups. Furthermore, predictors of force variability shifted from trait measures of pain intensity and pain interference at the low force level to state measures of pain intensity at the high force level. Our observations show that motor-evoked jaw pain is associated with increases in force variability that are predicted by a combination of trait measures and state measures of pain intensity and pain interference.
