A clinical trial to investigate the relative effectiveness of acetaminophen with caffeine as opposed to cervical manipulation in the treatment of tension-type headache

Abstract

Tension-type headache is generally accepted as the most common form of headache and has been shown to have a great impact on work and social activities (Shwartz et al. 1998). Tension-type headache occurs in 39% of people who suffer from headache symptoms with a higher incidence among females, and a peak in the 25-44 year old age group (Wong et al. 1995). The purpose of this study was to investigate the relative effectiveness of 1000mg acetaminophen (paracetamol) combined with 130mg caffeine as opposed to cervical manipulation as a treatment for tension-type headache.
