Method for evaluating scapulothoracic joint position sense and a system thereof are disclosed

Abstract

This invention discloses a method and system for assessing scapulothoracic joint position sense. The method includes the following steps: providing a transmitting module positioned on the acromion of the subject; projecting a test beam onto an object using the transmitting module to form a test spot on the object; capturing the image of the test spot on the object as the subject moves using an image capturing module to generate an assessment image; and performing calculations based on the test position information and target position information from the assessment image using a processing module to generate an assessment result. Therefore, the scapulothoracic joint position sense assessment method and system of this invention provide convenience for assessing whether a subject's scapula is normal.
