Chronic back pain may benefit from reprocessing therapy

Altering patients’ pain-related beliefs through psychological treatment appeared to supply them sturdy relief for chronic back pain, according to outcomes of a randomized clinical trial published in JAMA Psychiatry.

“Leading psychological interventions for pain sometimes present the causes of pain as multifaceted and aim primarily to enhance functioning and secondarily to reduce pain,” Yoni K. Ashar, Ph.D., of the Department of Psychiatry at Weill Cornell Medical College in New York, and colleagues wrote. “[Pain reprocessing therapy (PRT)] emphasizes that the mind actively constructs primary persistent pain in the absence of tissue damage and that reappraising the causes and threat value of pain can reduce or eliminate it.”

The researchers sought to determine whether or not PRT might alter patients’ beliefs surrounding the causes and threat value of pain to supply vital and lasting relief from major persistent again pain. The trial took place in a university research setting between November 2017 and August 2018 and included longitudinal purposeful MRI and 1-year follow-up assessment.

Ashar and colleagues compared PRT with open-label placebo treatment and with regular care among a community sample. Participants randomly assigned to PRT (n = 50) accomplished one telehealth session with a doctor and eight psychological treatment classes over 4 weeks. Treatment included cognitive, somatic, and exposure-based techniques, with the goal of serving patients to see their pain as associated with non-dangerous mind exercise as a substitute for peripheral tissue injury.

Participants randomly assigned to placebo (n = 51) obtained an open-label subcutaneous saline injection in the back, and people randomly assigned to usual care (n = 50) maintained routine ongoing care. Main outcomes and measures included 1-week imply again pain depth rating from zero to 10 after treatment, pain beliefs, and functional MRI assessments of evoked pain and resting connectivity.

A total of 151 adults (mean age, 41.1 years; 54% women) reported mean pain of low to reasonable severity and a mean pain length of 10 years at baseline. The researchers noted giant group variations in pain at posttreatment, with a mean pain score of 1.18 among the PRT group, 2.84 among the placebo group, and 3.13 among the usual care group. A complete of 33 of fifty participants (66%) randomly assigned to PRT reported having no pain or virtually no pain at posttreatment compared with 10 of 51 participants (20%) randomly assigned to placebo and 5 of 50 participants (10%) randomly assigned to regular care. At 1-year follow-up, treatment results continued, with a mean pain score of 1.51 among the PRT group, 2.79 among the placebo group, and three among the usual care group.

Compared with placebo, PRT appeared linked to reduced responses to evoked back pain in the anterior midcingulate and the anterior prefrontal cortex based on longitudinal fMRI. It additionally confirmed different optimistic neural outcomes in contrast with usual care and each management group.

“Our findings raise key prospects in regards to the nature and treatment of primary [chronic back pain],” Ashar and colleagues wrote. “Altering fear- and avoidance-inducing beliefs in regards to the causes and risk worth of pain might present substantial, sturdy pain relief for people with primary [chronic back pain].”
