Description

Technical Field

[0001] The present invention relates to a laser measurement system and method for shoulder-humerus three-dimensional data. Background Art

[0002] The positions of the scapula and the humeral head have a great influence on the function and pain condition of the entire upper limb, and even a slight change in the alignment can cause great discomfort and dysfunction. This is because the shoulder joint is not an independent joint but a complex composed of the clavicle, scapula, humerus and multiple joints. Therefore, any injury to any part of this complex will cause compensation in one or more parts, leading to pain. As the most distal and most flexible bone in this complex, the humerus is the most prone to position changes and injuries; while the scapula, as the stable foundation of the humerus, will also bring various problems once stability problems occur. Multiple studies have shown that in patients with shoulder pain, changes in the alignment of the humerus and scapula will occur several years before the onset of pain. Therefore, the position changes of the humerus and scapula are also predictors and evaluation factors for shoulder pain and upper limb dysfunction. Quantitatively measuring the position of the humerus is crucial for evaluation and subsequent treatment.

[0003] However, it is often difficult to judge the evaluation of the positions of the scapula and the humerus at present. The reasons are as follows: First, the positions of the scapula and the humerus affect each other. Therefore, when evaluating, it is necessary to comprehensively consider their respective positions to judge the degree of absolute and relative position changes. Second, although in the process of scientific research, three-dimensional motion capture or ultrasonic devices are often used to judge, in clinical practice, it is very difficult to accurately judge the small-angle position changes of the scapula and the position changes such as anterior dislocation, downward subluxation, and rotation of the humerus by naked eyes and palpation.

[0004] Therefore, the present invention aims at the above problems and proposes a simple clinical solution, that is, through a portable measurement device, accurately measure the relative and absolute position changes of the scapula and the humerus of the subject, making the screening and prevention of shoulder pain and upper limb dysfunction more feasible.
