Technical Field

The invention relates to the technical field of medical assistance, in particular to a level measurer for three-dimensional motion analysis mark points.

Background

The three-dimensional motion analysis technology is a commonly accepted means for fine assessment of motor function abnormality at home and abroad at present, and is also one of the most objective methods for assessing motor function abnormality at present. The three-dimensional motion analysis data is an important link for evaluating the diagnosis of the abnormal motion function of a patient in the acquisition process, the fluorescent marker points with the light reflection effect are placed at the designated positions on the body surface of the subject, and the accurate positioning of the positions is the most important premise for the reliability of the data.

Three-dimensional motion analysis data acquisition requires that two mark points of a heel and a instep are at the same horizontal height, but at present, the accuracy cannot be ensured by mainly depending on visual measurement judgment or common ruler measurement judgment in clinic. If the marked points of the heel and the instep are not at the same height, the estimated ankle flexion and extension movement angle is too large or too small, and the diagnosis and treatment of clinical diseases are affected.

At present, a horizontal measurer for assisting the placement of three-dimensional motion analysis mark points is temporarily unavailable clinically, and a common ruler or a U-shaped width ruler is mostly used for replacing the horizontal measurer. The ruler can only relatively measure the consistency of the heights on the basis of visual judgment, and cannot accurately determine whether two marking points are kept at the same horizontal height. And the time is long and the operation is inconvenient because the repeated confirmation is needed.

Therefore, what is needed is a level measurer for three-dimensional motion analysis marker points, which has a simple structure, is convenient to operate and observe, can save operation time, improve the accuracy of the positions of the fluorescent marker points in the three-dimensional motion analysis process, and avoid errors of visual judgment, thereby improving data acquisition accuracy.

However, such a marker level meter for three-dimensional motion analysis has not been reported yet.
