title: Presence of post-concussion syndrome symptoms in patients with chronic pain vs mild traumatic brain injury.
abstract: OBJECTIVE
  Post-concussion syndrome (PCS) is a controversial diagnosis, in part because many symptoms may be present in other conditions, such as chronic pain (CP). However, direct comparisons between people with CP and mild traumatic brain injury (MTBI) are limited. The purpose of this study was to compare people with CP and MTBI on a measure of PCS symptoms.
  
  
  METHODS
  Group comparison between patients with CP and MTBI on the Rivermead Post-Concussion Questionnaire (RPCQ).
  
  
  METHODS
  Sixty-three patients with CP and 32 with MTBI were evaluated at the authors' institutions. Patients completed the RPCQ as part of their initial evaluation.
  
  
  RESULTS
  No group differences were found for total RPCQ scores. There were some differences in the proportion of patients endorsing specific symptoms. However, most people with CP endorsed symptoms consistent with PCS.
  
  
  CONCLUSIONS
  PCS symptoms are not unique to MTBI, and may be seen in conditions such as CP.
