BACKGROUND ATR is a common sports-related injury and is often managed with open surgical repair. After ATR repair most patients return(More)
BACKGROUND Beliefs about pain conditions appear to influence recovery in a variety of musculoskeletal conditions. Little is known about population beliefs about neck and arm pain. AIMS To evaluate population beliefs of three common musculoskeletal conditions: work-related neck and arm pain and whiplash injury (WAD). METHODS Mail-out surveys were(More)
INTRODUCTION Beliefs about pain are known to be important factors in recovery, most notably in LBP. Relatively less is known about the role of pain beliefs in Whiplash Associated Disorder (WAD). The widely advocated cognitive-behavioural approach to pain management necessitates cognitive factors such as pain beliefs be examined, even early after injury. The(More)
