Embodiment Construction

[0063] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0064] A method for quantitative evaluation of hand function rehabilitation based on the "ulnar deviation" movement of human hands, including a quantitative evaluation process, scoring result acquisition, and patient test steps for the "ulnar deviation" action. The quantitative evaluation process includes data collection, data preprocessing, evaluation Parameter calculation and evaluation result statistics, real-time capture and processing of three-dimensional space data of each joint point of the hand from finger to palm and wrist through optical motion capture equipment, and taking the healthy hand of the patient as the comparison object, taking the maximum ulnar angle, movement The scoring form of the average angular velocity during the process and the recovery percentage of the average angular acceleration during the exercise gives the...

Abstract

The present invention relates to a hand function rehabilitation quantitative evaluation method based on hand 'ulnar deviation' motion. Combined with an existing computer vision and optical motion capture technology and combined with computer intelligent computing, three-dimensional data of each articulation point of fingers, palm and wrist of a hand portion are captured and processed in real time, and compared with a healthy hand of a patient, quantitative description about the ulnar deviation motion of the patient during the whole rehabilitation training process is given in a recovery percentage score form. Combined with information of speed and acceleration of the hand motion, doctors are assisted to diagnose diseases, and through a period of continuous evaluation, the doctors and the patient can clearly understand quantitative rehabilitation degree variation of the affected hand during the period.

Description

technical field [0001] The invention relates to the application of motion capture and intelligent computing technology including various joints and palms of the human hand in the field of hand function rehabilitation evaluation, and specifically relates to a quantitative evaluation method for hand function rehabilitation based on the "ulnar deviation" movement of the human hand. It belongs to the field of electronic information and intersects with the field of rehabilitation medical evaluation. Background technique [0002] Epidemiological survey results show that the annual incidence of stroke in my country is 217 / 100,000, the number of patients exceeds 1.5 million, and the disability rate is as high as 86.5%. In the process of long-term rehabilitation training for patients, the recovery of hand function plays an important role in improving the quality of life of patients in the later stage. With the intervention of rehabilitation training and treatment, some patients will ...
