Abstract

The invention discloses a vestibular function detecting device based on vestibular electrical stimulation and head movement tracking. The vestibular function detecting device based on vestibular electrical stimulation and head movement tracking comprises a vestibular electrical stimulation device, a head posture detecting device and a control computer. The non-invasive vestibular detecting device can be provided, the comfort level of a detected person is improved, the vestibular detecting device is coupled with the forehead, the left and right temples or mastoid processes behind the ears through electrode plates to achieve connection between the current and the human body, and the detecting device is used for changing the input signals of the semicircular canals of the vestibular organ and the otolith. The head posture detecting device detects the posture changes of the detected person through a three-dimensional posture sensor fixed to a helmet, achieves linkage of the control computer through a Bluetooth device, and is used for detecting the head posture changes. The control computer is used for controlling the simulation current type, intensity and time of the vestibular electrical stimulation device, receiving and processing data of the three-dimensional posture sensor in the head posture detecting device, and displaying related parameters in real time. By matched use of the above devices, the head posture changes caused by vestibular electrical stimulation can be detected, and the device can be used for detection, selection training and research of the vestibular function.

Description

technical field [0001] The invention relates to the field of biomedical engineering research, in particular to a vestibular function detection device based on vestibular electrical stimulation and head movement tracking. Background technique [0002] The vestibular system has a dual role of stabilizing vision and stabilizing upright balance through motor neurons originating from the vagus organ and terminating in the muscles of the eyes, neck, trunk and extremities. Balance disturbance and vertigo occur when vestibular function is impaired, so quantitative testing of vestibular function plays an important role in the prevention of vestibular dysfunction. [0003] Ideally, testing the integrity of vestibular function requires testing the integrity of the vestibulo-ocular reflex and vestibular balance control pathways. Angular and linear acceleration of the head are sufficient stimuli to excite the vestibular cells. However, applying a real head acceleration to test the vest...
