Description

Vestibular tilting-translation stimulation device Technical Field The application relates to the technical field of vestibular stimulation training, in particular to a vestibular tilting-translation stimulation device. Background Vestibular systems play a critical role in body posture control, balance maintenance, and spatial orientation. Accurate vestibular perception is critical for integrating multisensory information and completing motor control tasks in the central nervous system. Currently, the study and training of vestibular function generally relies on various types of motor stimulation devices to simulate different motor patterns to assess or enhance the perceptibility of the vestibular system. Existing vestibular stimulation devices are largely classified into rotational and translational classes. The rotary device is often represented by a swivel chair, and stimulates the horizontal semicircular canal by rotating around the vertical axis, but it is difficult to effectively stimulate the vertical semicircular canal and the otolith organ (elliptic capsule, balloon). The translation device provides linear acceleration stimulation through linear motion and mainly acts on the elliptical sac, but the motion mode is single, and the change of the inclined posture cannot be simulated at the same time. Although some complex platforms (such as six-degree-of-freedom motion platforms and multi-axis simulators) can realize multi-dimensional motion, such devices are generally complex in structure, high in control system requirements, large in occupied area, expensive in manufacturing cost and difficult to popularize and apply in common laboratory or clinical environments. In addition, most of the existing devices can only provide single-mode stimulation, lack the capability of flexibly combining tilting motion and translational motion, are difficult to simulate complex multi-mode motion scenes in real environments, and limit the research and training effects of the comprehensive perception function of the vestibular system. Therefore, there is a need for a device that is relatively simple in structure, flexible in control, and capable of providing tilting and translational stimuli independently or cooperatively to meet the multi-dimensional needs of vestibular function research and perception training.
