Background technique

Three-dimensional motion analysis technology is a fine evaluation method for abnormal motor function widely recognized at home and abroad, and it is also one of the most objective methods for the evaluation of abnormal motor function. Three-dimensional motion analysis data is an important part of evaluating the diagnosis of abnormal motor function of patients during the acquisition process. It places fluorescent markers with reflective effects on the designated positions on the subject's body surface. The accurate positioning of the positions is the most important prerequisite for reliable data. .

The acquisition of 3D motion analysis data requires that the two marked points of the heel and the dorsum of the foot be at the same level. At present, the clinical judgment mainly relies on visual judgment or ordinary ruler estimation, and the accuracy cannot be guaranteed.
