Effects of acupuncture and medical training therapy on depression, anxiety, and quality of life in patients with frequent tension-type headache: A randomized controlled study

Acupuncture and medical training therapy showed significant benefits for patients with tension-type headache, especially in relieving symptoms of depression and anxiety, according to an important German study published in the journal Cephalalgia in 2023.

Tension-type headache is the most common neurological disorder worldwide and is classified as the second leading cause of chronic disease and injury. This type of headache may present in a frequent episodic form, affecting patients between 12 and 180 days per year, or in a chronic form, affecting people for more than 180 days per year. Approximately 60% of patients report significant limitations in their social activities and work capacity, while those with chronic headache have a quality of life comparable to that of patients with migraine. Beyond the physical symptoms, the condition is frequently associated with anxiety and depressive disorders, and patients with chronic headache have a three- to fifteen-fold higher risk of developing mood disorders compared with healthy individuals.

This randomized controlled clinical trial was conducted at Hannover Medical School in Germany with 96 adults suffering from frequent episodic or chronic tension-type headache. The participants, with a mean age of 38.7 years and predominantly women, were divided into four treatment groups: acupuncture alone, medical training therapy alone, a combination of both treatments, or usual care without additional intervention. Over six weeks, the intervention groups received twelve treatment sessions each, with decreasing frequency over the period. The researchers assessed depressive symptoms with the Patient Health Questionnaire, anxiety with the Generalized Anxiety Disorder Questionnaire, and health-related quality of life with the Short Form Questionnaire, at five time points: before treatment, at the end of the six weeks, and three and six months after baseline.

The results showed that both acupuncture alone and its combination with medical training therapy significantly reduced depression scores compared with medical training therapy alone or usual care. In the acupuncture group, depression scores decreased on average by two points during the first six weeks, remained stable at three months, and reached a reduction of 2.7 points at six months. The combined therapy group showed similar reductions, with decreases of 2.7 points during the first six weeks. For anxiety, acupuncture showed consistent benefits across all assessment time points, with reductions of 25% to 36% in scores.

Physical quality of life also improved significantly, with increases of up to 30% in the acupuncture group and 20% in the combined therapy group at six months. The researchers observed that improvements in depression, anxiety, and quality of life were associated with a reduction in the frequency of headache days, suggesting a relationship between relief of physical symptoms and psychological well-being.

For patients suffering from frequent tension-type headache, these findings represent concrete hope for more comprehensive treatment with fewer side effects than traditional pharmacological options. Acupuncture emerges as a particularly promising alternative, not only for pain control but also for the treatment of the emotional aspects of this condition, which are frequently overlooked. For health professionals, the study provides robust evidence that acupuncture can be incorporated as an effective complementary therapy, especially considering that no serious adverse events were recorded throughout the research. The finding that acupuncture appears to play a central role in the therapeutic effects, even when combined with other approaches, reinforces its clinical relevance and suggests that it may be the most important component in multidimensional treatment protocols.

The study has some important limitations that should be considered when interpreting the results. The relatively high number of dropouts in the medical training therapy group may have influenced the results, and the absence of participant blinding represents a methodological limitation inherent to acupuncture trials. In addition, recruitment through regional media may have created selection bias, attracting mainly patients with specific interest in the treatments offered. The combined therapy group faced a greater time burden, which may have generated organizational stress in some participants.

Future studies would benefit from larger samples and better control of factors such as adherence to the exercise program and seasonal influences on mood.

In conclusion, this research provides convincing evidence that acupuncture, alone or in combination with medical training therapy, represents a valuable therapeutic option for patients with tension-type headache, providing benefits that go beyond simple pain control to encompass overall psychological well-being. The sustained results over six months demonstrate that these benefits are durable, offering patients a safe and effective alternative for comprehensive management of their condition. For the future of tension-type headache treatment, these findings underscore the importance of integrated approaches that consider both the physical and emotional aspects of the disease, positioning acupuncture as a central component of this holistic therapeutic strategy.
