Development of a questionnaire to identify ocular torticollis.

ABSTRACT

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.
