This single-blind randomized controlled trial with 41 adults explored two ways of treating chronic neck pain (CNP) -- pain lasting more than three months, often traced to a forward head posture that overloads the cervical spine. The researchers focused on the scapulothoracic region, the muscles connecting the shoulder blade to the rib cage and spine, because weakness in the middle and lower trapezius combined with tightness in the upper trapezius creates a muscle imbalance that drives neck pain and reduced neck mobility. One group performed a resistance exercise program targeting the weakened muscles directly; the other received trapezius massage targeting the tight ones, and both were compared head-to-head over four weeks. Adults aged 29 to 66 (mean 47.9, 22 men, 19 women) with confirmed chronic neck pain were split into a resistance-exercise group (21 people) and a massage group (20 people) at a South Korean clinic, training five days a week for four weeks. The exercise group used elastic bands for eight movements -- chin tucks, rows, and scapular retraction among them -- building from 10-15 up to 15-20 repetitions per set. The massage group received a standardized 20-minute trapezius massage combining myofascial release, trigger-point work, and friction techniques. Pain, neck motion, muscle tone, disability, and quality of life were all measured. Both approaches worked: pain, disability, and quality-of-life scores improved significantly within each group (p<.05 throughout). But head-to-head, resistance exercise pulled ahead on several measures. Pain dropped further with exercise (VAS change 2.67 vs. 2.30 points, p=.02), and disability scores on the Neck Disability Index fell more as well (p=.04). Quality of life improved more on both the physical (p=.04) and mental (p<.001) subscales. Muscle tone and stiffness in the upper trapezius -- the very muscle massage directly targets -- actually decreased more in the exercise group (p=.01 to .03), suggesting that strengthening the weakened muscles around it relieved tension more effectively than massaging the tight muscle itself. Cervical rotation, often the most functionally limited movement in this condition, also improved more with exercise (p<.001 to .02). Flexion, extension, and side-bending improved to a similar degree in both groups, with no meaningful difference in muscle elasticity. For people managing chronic neck pain, a structured resistance program targeting the shoulder-blade stabilizers may offer more relief than massage alone, particularly for pain, disability, quality of life, and neck rotation -- and it requires only elastic bands, making home practice feasible. The trial did not track adverse events or follow participants beyond the 4-week program, so how long the gains last is unknown. It also did not directly measure whether the weakened muscles actually got stronger, so the exact mechanism behind the improvement is inferred rather than proven. Larger studies with longer follow-up periods are needed.
