Clinical Feasibility of 2-Dimensional Video Analysis of Active Cervical Motion in Congenital Muscular Torticollis

Purpose: The purpose of this study was to evaluate the clinical feasibility of using a 2-dimensional (2D) video analysis (VA) system compared with visual estimation (VE) for measurement of active cervical rotation and lateral flexion in infants with congenital muscular torticollis. Methods: Twelve infants participated in this study. Active cervical motion in rotation and lateral flexion was measured by VE and 2D VA. Results: Significant differences between VE and VA were found for left lateral flexion, right lateral flexion, and right rotation. Average total time for VA was 23.96 minutes. Conclusions: This study suggests that the use of VA may improve the measurement of active cervical motion to improve clinical assessment of infants with congenital muscular torticollis. However, VA time is excessive and, therefore, not clinically feasible. Further studies are indicated to explore other software for this application.
