Eye reflexes that stabilize gaze are essential in navigating daily life. One such reflex is the cervico-ocular reflex (COR). An important neural structure involved in the COR is the cerebellum, which facilitates proper gaze stability through sensorimotor integration to adjust eye movements accordingly. This reflex is tested by fixating the head in space and rotating the body around the neck. Thus, a rotating chair is needed to elicit proper cervical rotation while keeping the head fixed. The chair that was developed for this project was able to rotate to the specified amplitude (±0.5º of accuracy) and frequency. The parameters of the rotation amount, frequency, and amplitude can be adjusted as desired by the project guidelines. Our project aimed to improve upon existing chair models and develop a chair that can be used to assess the COR in neck pain populations.
稳定注视的眼反射在日常生活中至关重要。其中一种反射是颈眼反射（COR）。参与颈眼反射的一个重要神经结构是小脑，它通过感觉运动整合促进适当的注视稳定性，从而相应地调整眼球运动。该反射通过将头部固定在空间中并围绕颈部旋转身体来测试。因此，需要一把旋转椅来在保持头部固定的同时引发适当的颈部旋转。为该项目开发的椅子能够旋转到指定的幅度（精度为±0.5º）和频率。旋转量、频率和幅度的参数可根据项目指南进行调整。我们的项目旨在改进现有的椅子模型，并开发一种可用于评估颈部疼痛人群颈眼反射的椅子。
