Effect of acupuncture versus usual care on sleep quality in cancer survivors with chronic pain: Secondary analysis of a randomized clinical trial.

This study analyzed the sleep quality data from a published randomized clinical trial that evaluated the effect of electroacupuncture or auricular acupuncture versus usual care on pain relief among people who survived cancer. This analysis included a prespecified subgroup of 268 participants with co-occurring sleep disturbance and chronic musculoskeletal pain at baseline and found that patients who used acupuncture for pain relief demonstrated greater improvements in sleep quality compared with patients who received usual care. Sleep quality improvement by acupuncture was sustained after the treatment ended.
