Combination of acupuncture and medical training therapy on tension-type headache: Results of a randomized controlled pilot study

Tension-type headache is one of the most common types of headache and affects millions of people worldwide. This condition can present as frequent episodic, when it occurs between 1 and 14 days per month, or as chronic, when the person has headache on more than 14 days per month. For those who suffer with this condition, especially in the frequent or chronic form, there is an increased risk of overusing analgesic medications, which can lead to a vicious cycle of worsening headaches. For this reason, non-pharmacologic treatments take on special importance in the management of this condition.

Medical guidelines recognize that strategies such as relaxation, acupuncture, and therapeutic exercise can be valuable and well-tolerated alternatives for patients.

This study was conducted by German researchers with the goal of comparing the efficacy of acupuncture, medical training therapy, and the combination of both treatments against usual care in relieving pain in people with tension-type headache. Medical training therapy is a form of physician-prescribed physical therapy that combines strength, endurance, coordination, and flexibility exercises. The research was conducted as a randomized controlled clinical trial, considered the gold standard for evaluating medical treatments. Ninety-six adults between 18 and 65 years of age who suffered from tension-type headache were randomly divided into four groups of 24 participants each: one group received only usual care, another only acupuncture, a third only medical training therapy, and the fourth group received the combination of acupuncture and medical training.

Each active treatment group received 12 sessions over six weeks, and all participants were followed for three and six months after the start of treatment.

The results revealed important findings and some surprises. Only the group that received the combined treatment of acupuncture and medical training therapy showed a significant reduction in pain intensity compared with usual care. This reduction was substantial, reaching 38% in mean pain, 25% in maximum pain, and 35% in minimum pain three months after the start of treatment. Interestingly, neither acupuncture nor medical training alone showed significant differences from usual care, despite both producing considerable positive effects.

All groups, including usual care, showed important improvements in headache frequency, episode duration, and analgesic use. A notable finding was that more than 90% of participants in all groups had at least a 50% reduction in headache frequency at three months. At six months, all intervention groups maintained responder rates significantly higher than the usual-care group.

For patients suffering from tension-type headache, these results carry several important practical implications. First, they suggest that combining acupuncture with supervised therapeutic exercise may be more effective at reducing pain intensity than any single treatment. This is particularly relevant because many people seek alternatives to medication due to side effects or concerns about long-term use. For health professionals, the study offers evidence that integrated approaches can be superior to single treatments.

The researchers propose that the mechanisms of action of the two treatments are complementary: acupuncture may act primarily on the body's pain control systems, while therapeutic exercise may contribute to beneficial neuroplastic changes and autonomic nervous system regulation. It is interesting to note that the study also identified that patients with muscle tenderness in the head and neck region may benefit more from medical training therapy.

The study has some important limitations that should be considered. The dropout rate was relatively high, especially in the medical training therapy group, where nine of the 24 participants did not complete treatment. This may reflect the more physically demanding nature of this type of intervention. In addition, the evaluation period was relatively short, and the researchers used pain intensity as the primary outcome rather than attack frequency, which is more commonly used in headache studies.

The usual-care group showed surprisingly large improvements, which the researchers attributed to what they call "contextual healing effects," including participation in a medical study, education about the condition, and positive interaction with the health care team. This may have reduced the differences observed between groups. The study was also unable to adequately assess adherence to home exercise programs, which were an important part of the medical training therapy protocol.

Despite the limitations, this study provides valuable evidence that the combination of acupuncture and supervised therapeutic exercise may be an effective option for people with frequent or chronic tension-type headache. The results suggest that integrated approaches may offer benefits superior to single treatments for control of pain intensity. For those who suffer from this condition, it may be worth discussing with qualified health professionals the possibility of combining different non-pharmacologic treatment modalities. It is important to remember that both acupuncture and therapeutic exercise should be performed by experienced professionals to ensure safety and efficacy.

The study demonstrates that these interventions are generally safe, with only mild side effects reported, such as small bruises at acupuncture points or temporary initial worsening of symptoms. Future research with larger samples and longer follow-up periods will be important to confirm and expand these promising findings.
