Objective To test the feasibility of the semi-automated scoring system for the Toronto Western Spasmodic Torticollis Scale (TWSTRS) severity scale in patients with cervical dystonia.

Background Evaluation utilizing TWSTRS requires training and experience. We previously developed a system to measure neck angle by analyzing three-dimensional position obtained using Kinect, a marker-less three-dimensional depth sensor. The system can track patients’ faces and bodies, automatically analyze neck angles in real time, and semi-automatically calculate the TWSTRS severity scale score.

Design/Methods We compared TWSTRS severity scores calculated by the system against the video-based scores evaluated by a movement disorder-trained neurologist. Correlation coefficient analysis was then conducted. Absolute accuracy was measured using intra-class correlation (ICC 3,2) and 95% limits of agreement. For subscales, Cohen's kappa coefficient (κ) was calculated. A p-value of <.05 was considered statistically significant.

Results In total, 30 patients were enrolled. The average age was 52.3±16.0 years, and the male to female ratio was 3:2. The average disease duration was 11.3±12.7 years. The correlation coefficient analysis indicated a significant correlation between measurement by the system and the movement disorder-trained neurologist in the total scores (r=.596, p<.05) and in the total score of the automated part, which is purely based on the system, without the examiner’s impression (r=.655, p<.05). An adequate ICC (3,1) of .562 was obtained for total severity score [p<.001, 95% confidence interval (CI) .259-.765] and of .617 for the total automated part score (p <.001, 95% CI .336-.798).

Conclusions Our three-dimensional motion capture system, which can measure head angles and semi-automatically calculate the TWSTRS severity scale score utilizing a single depth camera, demonstrated adequate validity and reliability. This low-cost and portable system can be applied in the clinical setting by general practitioners treating cervical dystonia in order to help obtain objective measurements.
