Is this trial a fit for you?

Likely a good fit

Adults aged 18 and older with chronic pain (≥3 months) and a self-reported 1-week average pain of 4–9/10 at screening, referred to TOH Pain Clinic and meeting the pathway criteria.

Probably not a fit

Patients with pain intensities outside the 4–9/10 range or who do not complete the session may not experience benefit, and some may see no change in mood or pain.

What this trial studies

This interventional study tests a single Pain Reprocessing Therapy (PRT) session in adults with chronic pain referred to The Ottawa Hospital Pain Clinic. Forty participants will participate in one 4-hour PRT session and complete mood and pain questionnaires immediately before and after the session, then at 1 week and 1 month follow-up. A subset of participants will be interviewed about their experience. The study will assess recruitment feasibility, session completion, and whether the session improves mood and pain symptoms.

Why it matters

Potential benefit: If successful, a one-time PRT session could provide mood and pain relief for some patients with chronic pain.

How similar studies have gone: Prior work in pain reprocessing approaches suggests potential benefits, but the single-session model for PRT in this setting is relatively novel and feasibility-focused.
