Embodiment 1

[0071] Embodiment one: see Figure 1 to Figure 6 , this quantitative evaluation method for hand function rehabilitation based on the "finger adduction and abduction" action of the human hand is characterized in that the operation steps are as follows:

[0072] 1) Data collection: The hand function rehabilitation quantitative assessment equipment is used for data collection, and the hand bones and joint points information of the patient's healthy hand and the patient's hand are collected.

[0073] 2) Data processing: Calculate the maximum abduction angle difference, abduction speed, and average abduction speed of each finger according to the hand skeleton and joint point information obtained by the optical motion capture device in the hand function rehabilitation quantitative assessment equipment.

[0074] 3) Quantitative evaluation results: take the healthy hand of the patient as the reference object, and use the parameters calculated in step 2) to compare the patient hand and...

Embodiment 2

[0076] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0077] The steps of data collection in the hand function rehabilitation quantitative evaluation method based on the "finger adduction and abduction" action of the human hand in the step 1) are as follows:

[0078] a. The subject takes a sitting position, puts the upper arm on the side of the body, bends the elbow, spreads the palms of the hands together, straightens and stretches the palms downward naturally, and places them on the hand function rehabilitation quantitative evaluation equipment (such as Figure 6 As shown in ), there is a work area on the left and right sides of the hand function rehabilitation quantitative evaluation equipment, which are respectively used for the detection of the left and right hands of the tester, and the data collection and establishment of the healthy hand;

[0079] b. Under the guidance of a doctor, the patient collects an...

Embodiment 3

[0083] Embodiment 3: This hand function rehabilitation quantitative evaluation method based on the "finger adduction and abduction" action of the human hand includes the quantitative evaluation process of the "finger adduction and abduction" movement, the acquisition of the evaluation result of the "finger adduction and abduction" action, and the "finger adduction and abduction" movement evaluation method. "Adduction and Abduction" motion patient test procedure.

[0084] See Figure 6 , the present invention uses the optical capture device (3) to capture and acquire information on human hand bones and joint points in real time, wherein the optical capture device (3) consists of a binocular grayscale camera and three infrared detectors. The definition method of the three-dimensional coordinate system: take the midpoint of the binocular grayscale camera as the origin, and the definition method of the X, Y, and Z axes is as follows Figure 4 shown.

[0085] The quantitative eva...

Abstract

The invention relates to a hand function rehabilitation quantitative evaluation method based on 'finger adduction and abduction' actions of a human hand. Based upon computer vision and optical motioncapture technologies, and in combination and computer intelligent computing, information of skeleton and various articulation points of the human hand can be acquired in real time. Information of an affected hand and a healthy hand of a patient can be computed on the basis of a current rehabilitation evaluation standard, and an evaluated value is applied to quantitative description of wrist back stretching action of the patient in an entire rehabilitation training process. Meanwhile, in combination with such information as speed, acceleration and the like of hand motions, doctors can be assisted in disease diagnosis. According to the quantitative evaluation method provided by the invention, a hand function recovery degree of the patient can be objectively and effectively reflected, so as to bring about benefits for the doctors in treating the patient and for patient's self-rehabilitation.

Description

technical field [0001] The invention relates to the application of motion capture and intelligent computing technology in the field of hand function rehabilitation evaluation, in particular to a quantitative evaluation method for hand function rehabilitation based on the human hand's "finger adduction and abduction" action. It belongs to the field of electronic information and intersects with the field of rehabilitation medical evaluation. Background technique [0002] Stroke is one of the important acute and chronic diseases that endanger human health in the world. Its morbidity, prevalence and disability rate are high, and it is also one of the three major causes of death of the global population. The annual incidence of stroke in my country is 2.17 / 100,000, the number of patients exceeds 1.5 million, and the disability rate is as high as 86.5%. During the long-term rehabilitation training process of patients, the recovery of hand function plays an important role in impro...
