Photophobia and Phonophobia in Tension-Type and Cervicogenic Headache

Light and sound-induced discomfort and pain thresholds were measured in 26 patients with cervicogenic headache, in 40 patients with tension-type headache, and in 100 headache-free controls. Neither headache group was significantly different as to photophobia and phonophobia, but both were significantly more sensitive to light and sound than controls ( p<0.0001), even when patients were tested in the headache-free period ( p<0.05). Episodic and chronic tension-type headache had similar photo- and phonophobia thresholds ( p≥0.7). Tension-type headache patients were more photo- and phonophobic during headache than outside attack ( p<0.05), but this was not true for cervicogenic headache ( p>0.56). In cervicogenic headache patients, photophobia ( p<0.05) but not phonophobia ( p=0.28) was greater on the symptomatic side than on the non-symptomatic side.
