The aim of this study was to quantify the biomechanical features of the Sheffield Support Snood (SSS), a cervical orthosis specifically designed for patients with neck weakness. The orthosis is designed to be adaptable to a patient’s level of functional limitation using adjustable removable supports, which contribute support and restrict movement only in desired anatomical planes. Methods: The SSS was evaluated along with two commercially available orthoses, the Vista and Headmaster. The orthoses were compared in a series of flexion, extension, axial-rotation and lateral bending movements. Characterisation was performed with twelve healthy subjects with and without the orthoses. Two Inertial-Magneto sensors, placed on forehead and sternum, were used to quantify the neck range of motion (ROM). Findings: In its less rigid configuration, the SSS was effective in limiting movements only in the desired planes, preserving free movement in other planes, whereas the headmaster was only effective in limiting the flexion. The percentage of ROM achieved with the SSS in its rigid configuration is equivalent (P > 0.05, effect size < 0.4) to that achieved with the Vista, both in trials performed reaching the maximum amplitude (ROM reduction: 25%-34% vs 24%-47%) and at maximum speed (ROM reduction: 24%-29% vs 25%-43%). Interpretation: The SSS is effectively adaptable to different tasks and in its rigid configuration offers a support comparable to the Vista, although it has a less bulky structure. The chosen method is suitable for the assessment of ROM movements while wearing neck orthoses and easily translatable in a clinical context.
