Problems solved by technology

However, at present, the qualitative analysis of lower limb functional rehabilitation evaluation is highly subjective, relying on manpower is inefficient, and there is no automatic and accurate identification method for identifying whether the left or right foot is in the support phase or the swing phase, and it has not been seen in stroke Literature report on using intelligent system to automatically calculate parameters related to stance phase and swing phase in quantitative assessment method of patient's lower extremity rehabilitation

Embodiment 1

[0037] In this example, see figure 1 , a quantitative evaluation method for lower limb rehabilitation of stroke patients, the steps are as follows:

[0038] a. Data acquisition: According to the data acquisition rate of 120 frames per second, through the whole body motion capture system, capture in real time and use the intelligent computer system II to process the three-dimensional coordinates and rotation data of human bones and each joint point for data acquisition;

[0039] b. Evaluate the degree of rehabilitation of the lower limbs: take the patient's healthy side foot as the reference object for comparison, and calculate the pace, frequency, and left and right footstep amplitude difference s based on the data collected in step a. 差 , healthy side footstep width s 健 , the comparison value a of the support of the healthy side and the comparison value b of the swing of the healthy side of the affected side, to obtain a standard data set for quantitative evaluation composed...

Embodiment 2

[0055] This embodiment is basically the same as Embodiment 1, especially in that:

[0056] In the present embodiment, in the step a, according to the medical standard of limb rehabilitation after stroke and the field test of the hospital, the step speed, stride frequency, left and right stride difference, the comparison value of the support of the healthy side and the affected side and the healthy side of the affected side are selected. The comparison value of side swing is used as the standard for quantitative evaluation. Due to the clinical symptoms of stroke patients such as slow gait speed, low gait frequency, and uncoordinated left and right feet, the gait speed, stride frequency, left and right stride difference, and the comparison value of the healthy side and the affected side support The five gait parameters, the swing comparison value of the affected side and the healthy side, can best reflect the motor function of the lower limbs. The whole body motion capture syste...

Embodiment 3

[0063] This embodiment is basically the same as the previous embodiment, and the special features are:

[0064] In this embodiment, in the step a, during the data collection, the patient is also provided with an auxiliary camera or video, and the image information collected by the camera or video is input into the intelligent computer system II, and through image analysis and processing, as Redundancy check data of quantitative evaluation data of lower limb recovery degree in stroke patients.

[0065] In this embodiment, the quantitative assessment method for lower limb rehabilitation of stroke patients, the steps are as follows:

[0066] ① First, the patient wears the motion capture system while wearing the brace and then captures the patient's picture facing the camera;

[0067] ②The patient walks 10 meters in a straight line facing the camera. At the same time, the test function and video recording function of the system are turned on to collect and calculate the data of the...

Abstract

The invention discloses a lower limb rehabilitation quantitative evaluation method for a patient suffering from cerebral stroke, and relates to a motion capture technology and application thereof in evaluation of limb function rehabilitation, in particular to a lower limb function rehabilitation quantitative evaluation method developed on the basis of the step speed, stride frequency, left and right stride length difference, healthy side and diseased side support comparison value and diseased side and healthy side swing comparison value. A whole body motion capture and display system and the lower limb function rehabilitation quantitative evaluation method are included. Accordingly, a method which evaluates the lower limb rehabilitation degree of the patient in the observation and scale modes and is adopted by traditional rehabilitation medicine is disregarded, the information technology and medicine are combined, gait parameters of double feet movement are analyzed through the whole body motion capture and display system, the healthy side foot of the patient serves as a comparing object, the improvement degree of the lower limb movement function of the patient suffering from the cerebral stroke is quantitatively evaluated in a rating mode, and important significance and value are achieved for human body health restoration and clinical medicine.

Description

technical field [0001] The present invention relates to a method for assessing the effect of human body rehabilitation, in particular to the application of a motion capture system in the quantitative evaluation of the degree of rehabilitation of moving parts of the human body, belonging to the field of electronic information, and in particular to the concept of integration of upper and lower limbs in the field of medical rehabilitation , belongs to the new generation of information technology strategic new industry. Background technique [0002] Cerebral stroke, also known as stroke, is an acute cerebrovascular disease. The age of onset is mostly over 40 years old, and the trend of onset is getting younger. The clinical manifestations of stroke patients generally include sudden numbness and weakness in one side of the face, arm or leg, difficulty walking, loss of balance or coordination. Compared with normal people, stroke patients show a smaller pace and shorter step lengt...
