Background:
Chronic pain is common following stroke, yet its characteristics are poorly understood.
Objectives:
To characterize the beliefs and perceptions of people with stroke who experience chronic pain and compare these to a non-stroke population with chronic pain.
Method:
An online survey of the Pain Beliefs and Perceptions Inventory for stroke and non-stroke individuals with chronic pain. Pain beliefs and perceptions, including perceived causes of pain, were compared across the two groups.
Results:
A total of 223 participants completed all questions. The stroke group (N = 106) reported significantly higher pain intensities (p = <0.001) than the non-stroke group (N = 117). In addition, they identified the stroke as the primary cause of their pain, whereas the non-stroke group identified a body injury as the primary cause. When compared to the non-stroke group, people with stroke were more likely to report their pain as being constant (p = <0.001), demonstrate a lack of understanding regarding cause(s) of their pain (p = <0.001), believe less that their actions contribute to their pain (p = <0.001), and have greater belief that their pain is permanent (p = <0.001).
Conclusion:
These findings emphasize differences in the beliefs and perceptions associated with pain after stroke, supporting the value of targeted attention from research and therapy perspectives. Significant differences in the pain experienced by stroke and non-stroke groups may reflect a poor understanding of chronic pain following stroke. Future educational programs for stroke survivors should be tailored. Targets for future educational interventions are identified and include causes of pain, an understanding of its behavior and potential for improved prognosis.
