Development of a questionnaire to identify ocular torticollis.

Ocular disease is one of the causes of abnormal head positioning. Conventionally, the behavioral characteristics of ocular torticollis patients are different from those of non-ocular torticollis patients, though research addressing the significance of this difference is yet limited. This prospective, cross-sectional study aims to develop a questionnaire based on the clinical features in children with abnormal head posture being ocularly assessed. Children aged ≥ 6 months who visited our rehabilitation medicine clinic with a chief complaint of abnormal head posture were included. Patients with apparent orthopedic and neurological diseases were excluded. A 10-item questionnaire was developed to analyze the behavioral characteristics of patients. The patients were divided into ocular and non-ocular torticollis groups according to ophthalmologic examination results. Thirty-four and 13 patients were assigned to the non-ocular torticollis and ocular torticollis groups, respectively. Five questions were finally selected and the questionnaire was scored as the sum of the scores for the each questions (yes = 1 point, no = 0 point). The median (interquartile range) score of the ocular torticollis group (3.0 (3.0-4.0)) was significantly higher than that of the non-ocular torticollis group (2.0 (1.0-3.0); p = 0.000).Conclusion: Our parent-reported torticollis assessment questionnaire may be useful for screening ocular torticollis. What is known: • Ocular disease is one of the various causes of abnormal head positioning. • The behavioral characteristics of patients with ocular torticollis are different from those of patients with non-ocular torticollis; research on this matter is limited. What is new: • We delveloped a questionnaire to differentiate ocular and postural torticollis and the score of the questionnaire was different between patients with or without ocular disease. • The questionnaire based on behavioral characteristics may help screening and determining the need of ophthalmic evaluation in patients with torticollis.
