PRT for Chronic Low Back Pain

9 lipca 2026 zaktualizowane przez: Andrea D. Furlan, University Health Network, Toronto

Pain Reprocessing Therapy for Chronic Low Back Pain: A Pilot Randomized Controlled Trial

The goal of this clinical trial is to learn whether Pain Reprocessing Therapy (PRT) is a feasible and acceptable treatment to complete for working-age adults (ages 18-65) with chronic low back pain. The main questions it aims to answer are:

Is PRT acceptable and feasible for people with chronic low back pain to complete? Does PRT help reduce pain intensity and interference, while improving functional outcomes in people with chronic low back pain?

Researchers will compare PRT to a Monitoring and Education Program to see whether participants who receive PRT experience greater improvements in pain, daily functioning, and well-being.

Participants will:

  • Be randomly assigned to the PRT group or the Monitoring and Education group
  • Participate in 8 intervention sessions over an 8-week period
  • Wear an activity monitor for 8 weeks
  • Attend a follow-up assessment after completing the intervention and another assessment 3 months later

Szczegółowy opis

Chronic low back pain (CLBP) is a prevalent and often debilitating condition that can impact daily functioning, occupational performance, and overall quality of life. In approximately 90% of individuals, CLBP persists in the absence of identifiable structural pathology and is thought to be related to altered processing of pain within the nervous system. As a result, there is a need for innovative, non-invasive treatment approaches that address these underlying mechanisms and move beyond traditional biomedical models of care.

This single-centre pilot study will evaluate Pain Reprocessing Therapy (PRT), a psychological intervention designed to modify maladaptive pain perceptions by targeting central pain processing and reducing fear associated with pain. The primary objective of this study is to assess the feasibility, acceptability, and preliminary effectiveness of PRT in individuals with chronic low back pain, while also evaluating recruitment, retention, and adherence to the intervention.

A total of 30 adults will be recruited and randomized to one of two groups. The intervention group will receive eight weekly sessions of PRT, while the control group (Monitoring and Education) will participate in a structured program consisting of health education and physical activity monitoring. Participants will complete validated questionnaires and physical and sensory assessments measuring pain intensity, functional status, mood, sleep, and physical performance at baseline, post-intervention, and at a three-month follow-up. Objective activity data will also be collected using wearable monitors throughout the eight week intervention period.

The results of this study will provide important preliminary data regarding the feasibility and potential clinical benefit of PRT and will inform the design of future larger-scale trials aimed at improving the management of chronic low back pain using PRT.

Broń i interwencje

Grupa uczestników / Arm
Interwencja / Leczenie
Aktywny komparator: Control Arm - Monitoring and Education
Participants will receive an 8-week monitoring and education program consisting of weekly sessions focused on pain education, symptom and activity level monitoring, and self-management strategies for chronic low back pain.
Inny: Monitoring and Education
Participants assigned to this arm will receive a structured Monitoring and Education program delivered over 8 weekly sessions. This program was developed as a research comparison intervention. Participants will receive education related to physical activity, healthy lifestyle habits, sleep, stress management, and chronic pain self-management through Pain BC's LivePlanBe+ modules, while also reviewing information collected through activity monitoring devices. Participants will complete study assessments and wear an activity monitor to measure physical activity and sleep patterns throughout the study. This arm allows researchers to compare outcomes between participants receiving PRT and those receiving education and monitoring.
Eksperymentalny: Treatment Arm - Pain Reprocessing Therapy
Participants will receive an 8-week Pain Reprocessing Therapy (PRT) program consisting of weekly therapist-led one-on-one sessions designed to reduce pain.
Behawioralne: Pain Reprocessing Therapy
Participants assigned to this arm will receive PRT, a psychological intervention designed to help individuals understand and manage their chronic pain by addressing how the brain and nervous system process pain signals. Participants will attend 8 weekly sessions over an 8-week period. The intervention includes, pain neuroscience education, somatic tracking exercises, and strategies to reduce fear and avoidance related to pain. In addition to the intervention, participants will complete study assessments and wear an activity monitor to measure physical activity and sleep patterns.

During the 8-week intervention period
Participant Satisfaction with the Intervention
Ramy czasowe: Immediately after the final intervention session, up to 8-week

Participant satisfaction will be assessed using a post-intervention satisfaction survey evaluating participants' overall experience with the intervention. The questionnaire includes items assessing satisfaction, engagement, and perceived experience of the intervention they were assigned to. Response options use Likert-type scales, including: (1) frequency-based items rated as Always, Usually, Rarely, and (2) agreement-based items rated as Agree, Neutral, Disagree. Both scale options will be combined when assessed to report overall participant satisfaction.

For scoring purposes, responses will be coded numerically (e.g., Always/Agree = 3, Usually/Neutral = 2, Rarely/Disagree = 1), with higher total scores indicating greater satisfaction and acceptability of the intervention.
Immediately after the final intervention session, up to 8-week
Participant Acceptability of the Intervention
Ramy czasowe: Immediately after the final intervention session, up to 8-week

Acceptability of the intervention will be explored through a qualitative interview conducted with a randomly selected subset of 8 participants from the Pain Reprocessing Therapy (PRT) intervention group. Interviews will explore participants' overall impressions of the intervention, level of engagement, perceived benefits and limitations, barriers to participation, and suggestions for improvement.

Interviews will be transcribed verbatim, and analyzed using qualitative analysis to identify key patterns and themes related to intervention acceptability.
Immediately after the final intervention session, up to 8-week
