A study in Poland compared MDT interventions to a control group that received therapeutic exercise, massage, and ultra-red radiation for patients with cervical derangement. Although not targeted at patients with a primary complaint of headache, the percentage of patients in the MDT group experiencing headache decreased from 80% to 3.33% whereas the percentage of patients in the control group experiencing headaches decreased from 83.87% to 51.61%. This indicates that MDT may be an effective treatment for headaches with a mechanical component.
