Weyer Jamora C, Schroeder SC, Ruff RM

Abstract Primary objective: The aim of this study was to examine the effect of
high chronic pain on (a) neuropsychological test performance and (b)
self-reported emotional complaints in persons suffering from Postconcussional
Disorders (PCD) after a mild traumatic brain injury (TBI). Research design: A
two-group comparative research design was employed. Methods and procedure: An
outpatient sample of 66 patients with mild TBI and PCD using the Ruff
Neurobehavioural Inventory (RNBI) and a neuropsychological test battery. Main
outcomes and results: According to ANOVAs, no significant between-group
differences were found on neuropsychological test performances; however, the high
pain group had significantly more emotional residuals; particularly elevated on
the RNBI were the Anger and Aggression, Anxiety, Depression and Paranoia and
Suspicion sub-scales. Furthermore, an ANOVA found participants of the high pain
group reporting significantly higher impairments on the RNBI Cognitive, Physical
and Quality-of-Life composite scores and several RNBI sub-scales compared to
their pre-morbid functioning. Conclusions: High chronic pain exacerbates the
emotional aspect of PCD and, therefore, should be given special observance in
treatment settings.
