Abstract

This investigation assessed the utility of 3D motion analysis, in conjunction with radiological imaging (MRI, magnetic resonance imaging) and clinical assessment, to objectively measure head/neck motion and tremor in patients with cervical dystonia (CD). It also investigated the relationship between head/neck muscle volume and head/neck motion and posture in patients with CD. Nineteen CD patients participated in this study (age: 56.3 ± 14.4 yrs). Subjects were clinically assessed, completed MRI and 3D movement analysis. The following movements were recorded by a Vicon system (OMG, England) with 8 MX cameras (100 Hz): relaxed posture, and head/neck range of motion in the sagittal (flex/ext), ..
