Method, device and system for testing lower limb function testing index

Abstract

The invention relates to a method for testing a lower limb function testing index. The method comprises the following steps of: firstly, acquiring an RGB (Red Green Blue) image and a depth-of-field image of a tested personnel to determine an initial body image of the tested personnel; according to the initial body image, determining initial coordinates of a preset position on the body of the tested personnel and storing the initial coordinates for subsequent computation use; then acquiring a body image, which is shot by a 3D (three dimensional) image sensor in real time and is used for the index to be tested, of the tested personnel; on the basis of the initial coordinates and the real-time body image for the index to be tested, calculating a test value of the index to be tested. The method overcomes the technical defects that in the prior art, labor is required for participating in to a great degree; consistency and accuracy of testing are promoted; meanwhile, the testing process is simpler.

Description

technical field [0001] The present application relates to the field of rehabilitation, in particular to a method, device and system for testing indicators of lower limb function tests. Background technique [0002] Physical therapy (PT, physical therapy) is the main component of rehabilitation medicine. Assessing the patient's body function is an important part of physical therapy. At present, before performing rehabilitation treatment on the patient, the doctor must first evaluate the patient's body function. During physical therapy, periodic evaluations are also performed in order to assess the progress of the treatment. [0003] At present, there are five main indicators for the functional evaluation of the lower limbs of the human body, including: knee joint angle, sit-stand test, single-leg standing balance time, start-walk time test, and 4-meter walk time. [0004] There are two main types of knee joint angle measurement methods that are more mature in the medical fi...

Problems solved by technology

However, the traditional goniometer method is to draw two straight lines on the patient's body surface, and set a center point at the joint, and then stick the goniometer on the body surface for measurement. According to the actual experience of the operator, the accuracy of the measurement varies greatly. This solution also requires manual operation, and the measurement accuracy of testers with different experience varies greatly

The second type of measurement angle method is the sensor solution, which binds the sensor to the human body, but the different parts of the sensor have a great impact on the test results, which is easy to cause test errors and lead to low evaluation accuracy

The other four indicators (sit-stand test, one-leg standing balance time, start-walk time test, 4-meter walk time) current test methods are manual stopwatch timing and manual counting, which is cumbersome to record, will introduce artificial timing errors, and even may be counted incorrectly

[0005] It can be seen that the existing technologies require a large degree of manual participation, and the evaluation results are greatly affected by human beings, resulting in large evaluation errors and low accuracy.
