AI Technical Summary

Technical Problem

Existing methods for assessing balance function mainly rely on active functional tests, which cannot comprehensively assess a patient's ability to respond to sudden external disturbances, especially for patients with insufficient muscle strength or cognitive impairment, resulting in inaccurate assessment results.

Method used

A balance function disturbance testing device was designed, including a standing platform and a disturbance mechanism. Through components such as telescopic rods, cams, rotating shafts, and rotation mechanisms, a passive disturbance scenario is simulated to conduct balance function tests under passive disturbance.

Benefits of technology

It can comprehensively assess a patient's balance function under various passive disturbance scenarios, providing more accurate test results, covering states such as tilting, swaying, sudden tilting and rotation, and improving the comprehensiveness and accuracy of the assessment.

Abstract

This invention discloses a balance function perturbation testing device, including a standing platform and a perturbation mechanism. The standing platform includes a base and a standing plate, the standing plate being disposed above the base and spherically hinged to the base. A groove is formed on the base surrounding the outside of the spherical hinge. The perturbation mechanism includes telescopic rods, a plurality of which are circumferentially arranged within the groove, with one end fixedly disposed within the groove, and the other end of each telescopic rod abutting against the bottom of the standing plate. Using this balance function perturbation testing device, by selecting different telescopic rods to extend or retract, the tilt direction of the standing plate can be adjusted, and the tilt angle can be adjusted according to the extension / retraction length of the telescopic rods, in order to test the balance function under different tilt states and obtain more accurate test results.
