Evidence has been accumulated suggesting that a dysfunction in pain inhibitory systems, ie
in 'diffuse noxious inhibitory controls '(DNIC)-like mechanisms, might be—amongst other

fibromyalgia. The aim of the present study was to look for similar impairments in chronic
tension-type headache (CTTH) as a regionally specific pain syndrome. Twenty-nine CTTH
