Effect Of Pain Reprocessing Therapy vs Placebo And Usual Care for Patients With Chronic Back Pain .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Effect of Pain Reprocessing Therapy vs Placebo and Usual Care for Patients With Chronic Back Pain: A Randomized Clinical Trial.
JAMA Psychiatry . 2022 Jan 1;79(1):13-23.One hundred fifty-one adults with chronic primary back pain were randomized to receive pain reprocessing therapy (n=50), open-label placebo (n=51), or usual care (n=50). The primary outcome was average back pain intensity over the past week at posttreatment. Secondary outcomes included pain-related disability, depression, anxiety, anger, sleep quality, and positive/negative affect. Outcomes were assessed at 1 month post-treatment and up to 12 months for follow-up. Overall, the results revealed that patients in the PRT group had significantly greater reductions in pain intensity compared to both control groups, with 66% reporting being pain-free or nearly pain-free after treatment. These improvements were largely sustained at 1-year follow-up. The findings suggest that PRT can provide substantial and durable pain relief by targeting pain-related beliefs.
