Description

Technical Field

[0001] The invention relates to the field of inspection technology, and in particular to a spontaneous nystagmus inspection device based on a sitting test. Background Art

[0002] When patients perform static balance training to maintain a balanced sitting posture, they need to train their sitting posture, especially for patients with severe balance deficiency. When performing static balance training, the patient's family members or medical staff usually hold the patient's waist and shoulders to adjust the patient's sitting posture. Long-term support will cause soreness in the arms of the patient's family members or medical staff, affecting the effect of adjusting the patient's position. Training devices are also used to support the patient's body to assist the patient in training.

[0003] To this end, those skilled in the art have conducted research and improvements, such as a sitting balance training device with application number 202322738259.3, which uses an electrical inspection and viewing device. This technical solution can limit and support the patient's shoulder position and assist the patient in static balance training.
