Chronic musculoskeletal pain and sleep disturbances are highly prevalent among active-duty military personnel and adversely affect force readiness and operational performance. Sleep and pain are bidirectionally linked: poor sleep amplifies pain perception, while pain disrupts sleep quality. Massage therapy is widely utilized for pain relief, but the mechanisms driving improvement remain unclear. This study evaluates whether a 6-week semi-standardized integrative therapeutic massage intervention improves sleep quality and pain outcomes compared with usual care in active-duty service members with chronic back, neck, or shoulder pain. Objective sleep parameters will be tracked continuously using wrist actigraphy alongside prospective daily sleep and pain diaries. The study also explores whether sleep changes statistically mediate pain relief.
