Abstract

Objective: The purpose of this study was to investigate the decision-making processes of physical therapists relating to evaluation and categorization of patients with headaches, including consistency with criteria proposed by the International Headache Society (IHS).Methods: A national online survey was distributed in cooperation with the Academy of Orthopaedic Physical Therapy of the American Physical Therapy Association. Three hypothetical patient case vignettes featuring headache disorders were used as assessment instruments. Additionally, data on physical therapist education, clinical experience, manual therapy training, self-efficacy, and familiarity & consistency with IHS criteria were collected. Physical therapist identification and valuation of clinical features of headache disorders were also examined in the decision-making processes.Results: Among the 384 respondents, 32.3% classified the tension-type headache case consistent with IHS criteria. The cervicogenic and migraine headache cases were classified at 54.8% and 41.7% consistent with IHS categories, respectively. Experienced clinicians and those with formal manual training categorized patient presentations with greater consistency. Clinician familiarity with IHS classification criteria was low with 73.6% collectively somewhat and not familiar, while 26.4% of physical therapists were self-described as very or moderately familiar.Discussion: Clinicians' headache categorization was significantly affected by symptom misattribution and weighting of individual examination findings. Weighting by practitioners of clinical features varied markedly with greatest emphasis being placed on detailed manual examination procedures, including passive intervertebral movements. Inconsistencies in valuation of clinical features in headache categorization suggest a need for further formal education in physical therapy educational curricula and in post-graduate education, including of IHS criteria and classification.Level of Evidence: 2a.
