title: Predictors of responsiveness to physiotherapy management of cervicogenic headache.
abstract: A recent randomized controlled trial tested the effectiveness of therapeutic exercise and manipulative therapy on 200 subjects with cervicogenic headache. Although treatments were efficacious, 25% of patients did not achieve a clinically acceptable outcome--50% reduction in headache frequency. This study aimed to identify predictors from variables in subjects' demographics and headache history which might identify those who did or did not achieve a 50-79% or 80-100% reduction in headache immediately after the active treatments and 12 months postintervention. The results revealed no consistent pattern of predictors, although the absence of light-headedness indicated higher odds of achieving either a 50-79% [odds ratio (OR) = 5.45) or 80-100% (OR = 5.7) reduction in headache frequency in the long term. Headaches of at least moderate intensity, the patient's age and chronicity of headache did not mitigate against a successful outcome from physiotherapy intervention.
