A statistical interaction occurred with participants receiving a positive expectation instructional set reporting expectations for less pain with quantitative sensory testing (QST) following spinal manipulative therapy (SMT) and those receiving a negative expectation instructional set reporting expectations for greater pain. Error bars represent 1 standard error of the mean (SEM). * indicates significant change at p ≤ 0.05.<p><b>Copyright information:</b></p><p>Taken from "The influence of expectation on spinal manipulation induced hypoalgesia: An experimental study in normal subjects"</p><p>http://www.biomedcentral.com/1471-2474/9/19</p><p>BMC Musculoskeletal Disorders 2008;9():19-19.</p><p>Published online 11 Feb 2008</p><p>PMCID:PMC2270829.</p><p></p
