Lateral C1-2 Joint Pulsed Radiofrequency Application in the treatment of Cervicogenic Headache

The primary objective in this study is to compare the effectiveness of lateral C1-2 pulsed radiofrequency application (LPRF) in comparison with conventional C3-5 facet denervation (MBRF) in patients with clinically defined cervicogenic headache.

Oxygen treatment for cluster headache attacks at different flow rates. A double-blind, randomized, cross-over design study.

Primary: To study whether there is a difference in treatment effect between oxygen at flow rates of 7 L/min versus 12 L/min in the acute treatment of cluster headache attacks. Secondary: - Identifying subgroups in which oxygen at flow rates of 7 L/…
