A study published online August 26 in Pain Medicine reports that psychological characteristics including anxiety figure prominently in patients’ response to interventional management procedures for chronic paraspinous pain. The study, conducted by researchers from the National University of Ireland in Galway, examined the psychosocial profile of 71 patients with a diagnosis of chronic myofascial pain of the paraspinous muscles who responded or did not respond to trigger point injection. Treatment effectiveness was then assessed by telephone interview at both 1 week and 1 month following the intervention.
The research team used pain related physical interference as the measure of outcome. They found that patients who exhibited lower levels of anxiety before treatment, as well as greater ability to accept pain, responded better to the trigger point therapy. Anxiety was found to be the strongest predictor of effectiveness.
