This randomized comparative trial with 70 adults explored whether connective tissue massage (CTM) or classical massage (CM, the "Swedish" style widely used in clinics) works better for chronic mechanical low back pain -- pain and stiffness in the lower back lasting more than 12 weeks with no specific structural cause like fracture or infection. CTM manipulates the skin and underlying fascia with pulling strokes, thought to trigger reflex effects on the autonomic nervous system (the body's automatic regulator of heart rate, blood pressure, and circulation). CM instead strokes and kneads muscle tissue, releasing endorphins and stimulating vascular pressure receptors to ease pain and support autonomic balance. The study compared which method controls pain better and whether either shifts autonomic activity more. Fifty-five participants (28 in the CTM group, 27 in CM, average age around 37) completed the full protocol: a hot pack plus a lumbar stretching and strengthening routine, combined with 20 sessions of their assigned massage over four weeks, five days a week. Pain was tracked on a 10-cm visual analog scale (VAS) at baseline, weekly, post-treatment, and at a six-week follow-up. Heart rate, blood pressure, and skin temperature were measured with standard clinical devices, while disability, quality of life, and sleep quality were tracked with validated questionnaires (Oswestry Disability Index, SF-36, and the Pittsburgh Sleep Quality Index). Both massages sharply reduced pain by the end of treatment and kept it low at six weeks (P < .001 for both, meaning the improvement is very unlikely to be chance). CM pulled ahead of CTM only briefly, at the two-week mark (1.90 vs 2.60 cm on the VAS, P = .04, a real but small and temporary difference), with no gap between the techniques at any other checkpoint. Peripheral skin temperature rose significantly in both groups (indicating improved circulation), but heart rate, blood pressure, and deeper trunk temperatures held steady in both. Disability, overall quality of life, and sleep quality all improved substantially and similarly in both groups; the one lasting difference was that CTM patients reported better emotional well-being at six weeks than CM patients (P = .03). No adverse events occurred with either technique. For practitioners and patients, the takeaway is reassuring rather than decisive: both CTM and CM are safe, effective options for chronic low back pain paired with heat and exercise, so the choice can rest on training, preference, or CTM's modest edge in longer-term mood rather than on a clear winner for pain relief. Limitations: one physiotherapist delivered every treatment and assessment (no blinding), the trial ran at a single center, and roughly one in five participants dropped out under the demanding five-day schedule. Future trials against a no-treatment control would clarify how much benefit comes from technique itself.
