thoracic pain
REGRESSION
Spinal manipulation in addition to thoracic exercise was more effective than thoracic exercise alone for improving thoracic pain and quality of life at the end of the 8th session of care. The advantage of including spinal manipulation was not found at the 12-week follow-up because improvement abated in the manipulation group, whereas improvement in the control group tended to be stable. This may be due to a short-term benefit of spinal manipulation in the treatment regimen or regression to the mean.
