BACKGROUND/OBJECTIVES: The main aim of the literature review was to determine whether different trigger point therapy techniques are effective in decreasing the intensity, frequency, and duration of tension-type headaches. An additional aim was to assess the impact of trigger point therapy on other physical and psychological variables in tension-type headaches. METHODS: This literature review was conducted in accordance with PRISMA guidelines, and the inclusion and exclusion criteria were developed using the PICOs strategy. Searches were carried out in four databases: PubMed, Science Direct, Cochrane Library, and PEDro. RESULTS: Of the 9 included studies with 370 participants, 6 studies were randomised controlled trials, 2 were pilot studies, and 1 was a case report. CONCLUSIONS: Trigger point therapy has reduced the duration, intensity, and frequency of headaches. Dry needling, ischaemic compression, Positional Relaxation Techniques, and massage protocols focused on deactivating trigger points are effective methods of unconventional treatment of tension-type headaches.
