AbstractThe study compared and contrasted medical, psychological, social and general behavioral functioning of American and Japanese low back pain patients and normal controls. The Sickness Impact Profile and a standardized Medical Examination Protocol for Pain instrument were used to assess all subjects. Findings showed that the American and Japanese low back pain patients had similar and significantly higher medical-physical findings than their respective controls. Likewise, the American and Japanese low back pain patients showed significantly greater psychological, social, and general behavioral dysfunction compared to control subjects. Finally, despite similar medical and physical findings, the Japanese low back pain patients were significantly less impaired in psychological, social, vocational, and avocational functioning than the American low back pain patients. It was concluded that there were significant cross-cultural differences between the American and Japanese low back pain patients, primarily in the psychosocial and behavioral areas. However, given the small sample size, any conclusion should be considered with caution; replication is needed before more definite conclusions are possible.
