Abstract
Non-pharmacological adjuncts are needed for chronic non-cancer pain in patients receiving long-term opioid therapy. Music listening may reduce pain, but most previous trials have used passive controls, limiting attribution of effects specifically to music. In this open-label, parallel-group, proof-of-concept randomized controlled trial, adults with chronic non-cancer pain receiving long-term opioid therapy were randomized 1:1 to four weeks of daily home-based music or audiobook listening. Analgesic outcomes included pain intensity, responder rates, quantity of pain relief, and multidimensional pain assessment; secondary outcomes included mood, quality of life, global impression of change, and safety. Of 70 participants entering the run-in period, 56 were randomized (28 per group). Adjusting for baseline pain intensity in a linear mixed-effects model, the between-group difference at end of treatment was −1.26 NRS points (95% CI −1.98 to −0.55; p<0.001; d=−0.70), favoring music. A ≥30% pain-reduction criterion was met by 21.4% of participants in the music group and none in the audiobook group (p=0.023). An exploratory between-group difference in pain intensity favoring music was also observed at follow-up. Other analgesic and secondary outcomes showed no significant between-group differences, although exploratory within-group improvements in mood and health-related quality of life were observed with music. Both groups reported overall improvement in global perceived change, with ratings numerically favoring music. No intervention-related harms were observed. These findings support an analgesic benefit of music beyond the structured listening experience shared with the active comparator. Daily self-administered music listening may represent a feasible, low-cost adjunct for chronic non-cancer pain in patients receiving long-term opioid therapy.
