Neck Braces and Driving Posture Affect Neck Mobility on Powered Two-Wheelers

Cervical spine injuries are a major concern for motorcyclists in traffic accidents and racing competitions. Neck braces aim to prevent cervical during by reducing the neck range of motion, keeping it under physiological limits. This work aims evaluate ability reduce mobility two driving postures associated with PTW configurations. The twelve volunteer subjects testing four on powered two-wheelers (scooter motorbike) is measured using an optoelectronic motion capture system. With tested worn, significantly reduced as compared all degrees freedom. However, only flexion/extension tested. suggests that these brace designs do not provide protection against loading directions may occur trauma. Furthermore, specific type each two-wheeler considered affects axial rotation, well postero-anterior caudo-cranial translations, thus underscoring need consider posture when evaluating devices.
