The efficacy of physiotherapy approaches in chronic tension-type headache: a systematic review and meta-analysis.

The short version

Chronic tension-type headache (CTTH) -- headaches on 15 or more days a month for at least three months -- is thought to involve tight, tender muscles in the head, neck, and face, though scientists are not fully certain why it happens. This systematic review and meta-analysis pulled together randomized trials testing physiotherapy-style treatments -- things like massage, exercise, acupuncture, and relaxation training -- to see whether they actually ease CTTH symptoms. The researchers followed a pre-registered research plan and searched two major databases through mid-2024, aiming to answer a focused question: do these hands-on and movement-based approaches beat sham treatment, no treatment, or medication alone? Two physiotherapist researchers with PhD degrees independently screened 237 studies and settled on nine randomized trials -- ranging from 25 to 169 patients each, mostly women, treated for 3 to 12 weeks. The approaches tested included trigger point massage, electroacupuncture, relaxation with muscle-tension biofeedback, yoga, and neck-and-shoulder strengthening exercises, among others. Seven of the nine trials had comparable enough data to combine mathematically (meta-analysis), and each study's methodological rigor was scored using a standard 11-item checklist. When the researchers pooled the numbers, physiotherapy approaches meaningfully reduced headache intensity compared to control (a large, statistically significant effect), cut the number of headache days per month by more than one day on average, and shortened how long headaches lasted -- all statistically significant improvements. A fourth measure, day-to-day headache impact on daily life, trended in favor of physiotherapy but did not reach statistical significance. Looking at individual studies: electroacupuncture beat sham treatment for headache intensity; combining a hands-on release technique with ibuprofen worked better than ibuprofen alone; and yoga added to standard medical care outperformed medical care by itself on several measures. Importantly, though, the researchers rated their overall confidence in these pooled results as low to very low -- the studies were small, methods varied a lot between them, and most carried some risk of bias. No serious side effects were reported in any trial. The takeaway is cautiously encouraging: physiotherapy-based approaches -- especially those combining exercise, hands-on techniques, or relaxation training with standard care -- show a real signal for easing CTTH symptoms, and they appear safe. But because the underlying evidence is still thin and inconsistent, these findings should not be read as proof that any one specific technique is the best choice. The authors call for larger, more consistently designed trials before physiotherapy can be confidently recommended as a primary CTTH treatment, though the current evidence supports trying it as a reasonable, low-risk complement to standard care.

Key findings

• This meta-analysis of 9 randomized trials found that physiotherapy approaches -- including massage, exercise, acupuncture, and relaxation/biofeedback training -- significantly reduced headache intensity, frequency, and duration in people with chronic tension-type headache (CTTH).
• The pooled improvement in headache intensity was large and statistically significant (SMD -1.17), and headache frequency dropped by more than one day per month on average with physiotherapy compared to control.
• Electroacupuncture, positional release technique combined with ibuprofen, and Raj yoga combined with standard medical care each outperformed their respective control conditions in individual trials.
• Despite these positive pooled results, the researchers rated their confidence in the evidence as low to very low for every outcome, due to small trial sizes, inconsistent methods, and risk-of-bias concerns across the 9 included studies.
• No serious adverse events were reported in any of the trials, suggesting physiotherapy approaches are a reasonably safe complement to standard CTTH care while stronger evidence is developed.
