Tension-type headache (TTH) is the most common form of headache that affects adults. A systematic review of ten studies concluded that manual therapies, such as those provided by doctors of chiropractic, are effective for improving overall wellbeing in TTH patients, as well as reducing TTH-related pain and disability. While the review did not find any one manual therapy to be superior, the authors report that optimal outcomes can be achieved by combining different techniques. Neurologia, September 2021
