Description
Technical Field
The embodiment of the invention relates to the field of medical instruments, in particular to a balance testing device and method.
Background
Cerebrovascular accidents are one of the major diseases leading to human dysfunction worldwide. Hand dysfunction after stroke is a major influencing factor preventing patients from returning to families and society. Up to 85% of patients after stroke are accompanied by unilateral upper limb hand movement dysfunction, but only less than 50% of patients can recover the upper limb hand movement function after 6 months of attack, the post-stroke hand dysfunction seriously affects the daily life quality of the patients, and simultaneously brings huge pressure and heavy burden to the society and families of the patients, so the development of post-stroke hand function rehabilitation is significant.
The assessment of the motor function of the upper limb of the stroke is roughly divided into two categories from the aspect of function: one is the evaluation method of which the variation of muscle strength is a standard-i.e. the bare-handed muscle strength test (MMT). However, the dyskinesia caused by stroke is the result of damage to the upper motor neurons, and the criteria of muscle strength and joint mobility are the criteria for correct assessment at the time of dyskinesia caused by damage to the lower motor neurons or the pathological changes of the motor system itself. Therefore, in recent years, the assessment method using the change in muscle strength as a standard is no longer used to assess the dyskinesia of stroke. The other type is a rating method for changing the overall motion mode into a standard mode, and the rating method is represented in various scales and is wide in variety. At present, evaluation methods such as Bruunstrom motor function evaluation method, Fugl-Meyer motor function evaluation method, MAS evaluation method, Rivermead motor index, Lindmark evaluation method, hemiplegic upper limb function evaluation method, SIAS evaluation method and the like are commonly used in clinic.
The assessment of the upper limb function of a patient with paraplegia after stroke is an international rehabilitation problem worthy of deep research. At present, the rehabilitation assessment of the upper limb dysfunction of the cerebral apoplexy does not have a uniform rehabilitation assessment standard, the upper limb dysfunction assessment of the rehabilitation medical field at present basically depends on a scale and is checked and evaluated individually and manually, and the problems of errors and reliability exist. For example, although the Fugl-Meyer motor function evaluation method is a 6-level stage of quantitative Bruunstrom motor function recovery, the evaluation method is complicated and time-consuming, and limits the application of the evaluation method to a certain extent. The grade 6 stage of Bruunstrom motor function recovery is simple and reliable, but the sensitivity is low, the stage is coarse, the floor effect is easy to appear, the recovery of the patient is possibly in the same stage for a long time, and the recovery positivity of the patient is influenced.
Except for relying on the rating scale, the hand function evaluation box is a common combination tool for hand function evaluation, and is generally divided into three sets, namely seven sets and eight sets. The fully functional hand function evaluation box generally comprises 1 grip dynamometer, 1 pinching dynamometer, 1 measuring tape, 1 tactile nylon monofilament 1 group, two-point discrimination test disc 2 groups, 1 finger circumference measuring scale, 1 plastic protractor, a portable box and a specification and the like. The detection equipment of above-mentioned hand function aassessment case can't detect arm balance ability, and equipment all separately sets up moreover, need carry whole detection case when detecting, if hand-carry above-mentioned detection equipment, because a large amount, small, so lose very easily. In addition, the detection data is read by the user, so that the deviation is large, and the limb ability level of the user cannot be reflected correctly.

and S142, determining the arm balance coordination capacity of the user executing the test based on the number of the target tests, the total number of the tests and the first evaluation threshold.
And/or
Based on the number of tests and the duration of each test, the method comprises the following steps:
s143, determining whether the test is successful or not based on the duration and the duration threshold of each test;
s144, determining the number of target tests which represent the test success;
s145, determining the duration of each target test piece on the test platform;
and S146, determining the arm balance coordination capacity of the user executing the test based on the total duration of all the target tests, the total duration corresponding to the total test quantity and a second evaluation threshold.
For example, a patient grips a handle of the balance testing device with one hand or two hands, timing is started after a testing small ball is placed above a testing platform, the timing is stopped when the small ball rolls to the edge above the testing platform and falls off the testing platform, the time T when the testing small ball is kept above the testing platform is recorded, the single time T is more than or equal to 2 seconds and is recorded as one effective time, namely the current test is a target test, each patient tests for 3-5 times, and the effective completion rate P and the average keeping time T of the patient are calculated, wherein P is the effective time/the total testing time multiplied by 100%, and T is the sum of the total time T and/effective time of the effective completion times;
and (3) grading the muscular strength, endurance, coordination and flexibility of the arm and hand functions according to the effective completion rate P of the patient, namely grading the effective completion rate, wherein the arm coordination and flexibility of different levels of reactions are different, and the higher the grade is, the better the arm function is, otherwise, the weaker the arm function is. Specifically, in this example, P < 30% is recorded as level 1, P < 80% and more than 30% is recorded as level 2, and P > 80% is recorded as level 3.
Further, the endurance, coordination and flexibility of the arm and hand functions of the patient are evaluated according to the average holding time T of the patient, T is less than 10 seconds and is recorded as very poor arm and hand functions, T is more than or equal to 10 seconds and less than 60 seconds and is recorded as slightly poor arm and hand functions, T is more than or equal to 60 seconds and is recorded as basically normal arm and hand functions, the treatment effect can be evaluated by the equipment according to the effective completion rate P and the average holding time T of the patient in the test, or the equipment has a data storage function and can store the result of each test, at the moment, the equipment can be compared with the current test result according to the previous test result of the patient, even the test result before treatment, and then whether the arm functions of the patient are improved or not is determined.
Further, the method of this embodiment further includes:
and S15, outputting the test result of the arm balance coordination ability of the corresponding user based on a target output mode, wherein the target output mode comprises voice broadcasting and a display mode through a display screen.
For example, the user may set an output mode for outputting the test result in the device in advance, or output the test result in the output mode selected after the test result is determined, and when the test result is determined, the device may output the test result based on the output mode selected by the user, so that the use flexibility of the user is improved, and the use requirements of the user in different scenarios are adapted.
In addition, the system can obtain more sensing data generated by the user in the testing process, and can analyze and determine data representing different physiological characteristics of the user based on the obtained sensing data, wherein the data comprises the physical, psychological, upper limb balance ability and the like of the user, so that the testing of the user is more detailed and comprehensive. For example, it can be determined whether the user feels stress during the test, or is labored for the test, i.e., whether the control of the upper limb movements is difficult, by the obtained hand temperature, grip strength, and heartbeat information of the user; determining whether the whole body or the upper limb action of the user is coordinated by obtaining the posture information of the user; the information such as whether the test small ball has a large direction and speed transition frequently and suddenly is determined by obtaining the information such as the rotation/rolling amplitude, the angular speed and the frequency of the test platform and/or the test small ball and the movement speed, and accordingly, the terminal can more finely determine the balance capability of the upper limb of the user.
In order to better illustrate the planarization testing method and the testing effect thereof in the present embodiment, the following description is made in more detail with reference to specific embodiments:
the first embodiment is as follows:
the balance testing device described above was used to evaluate the effects of patients with hand dysfunction and healthy volunteers with normal hand function:
1. patient information
TABLE 1 general conditions of patients
2. Preparation and test: the patient is in a sitting position or a standing position, the handle of the device is held tightly by the healthy side hand of the patient and the ipsilateral hand of the volunteer respectively, so that the plane of the test platform is kept horizontal, then the test ball is placed in the middle of the platform, and the timing is started.
If the small ball falls off from the platform rapidly (the retention time is less than 2 seconds), recording that the test fails; if the retention time of the small balls is more than 2 seconds, recording as the success of the test, continuously timing until the small balls fall off or the patient cannot maintain the stability of the platform, and recording the complete duration time t of the test;
3. repeating the step 2, and respectively repeating the test for 5 times for both the volunteer and the patient;
4. the success rate P and the average maintenance time T of the volunteers and patients were calculated separately.
The calculation method comprises the following steps: p is equal to the effective times/total test times x 100%;
t is the sum of the total time T of the number of valid completions/number of valid completions.
5. The test results were as follows:
table 2
The results of the first embodiment show that the balance test method can simply and effectively evaluate the severity of the disease, can discover whether the hand dysfunction exists in a patient with unobvious external symptoms as soon as possible, and is beneficial to early intervention and treatment of the patient.
Example two: early detection and diagnosis of paradoxical neglect and attention deficit
The specific method of evaluation is as follows:
1. when the patient is in the group, the muscle strength of the healthy upper limb is normal, the healthy hand can be lifted, and the balance detection device can be operated, and the detection method is the same as the first embodiment.
2. Since it is found during the test that the patient can grip the handle of the testing device and start the test, but the test cannot be completed normally, i.e. the effective time is short, the follow-up examination finds that the patient has some problems of visual disturbance and attention, such as: lateral neglect, poor attention, poor visual tracking, and poor visual perception.
5. The test results are as follows
Table 3
| Success rate P (100%) | Mean holding time T (seconds) | |
| |
0 | 0 |
| |
40 | 2.87 |
| |
20 | 3 |
The test result of the second embodiment shows that the test method can find whether the hand dysfunction and other dysfunctions exist in patients with unobvious external symptoms as soon as possible, and is beneficial to early intervention and treatment of the patients.
Example three: evaluation results of healthy and affected hands of patient
The test method is the same as the first embodiment, the evaluation results of the healthy lateral hand and the affected lateral hand of the patient are respectively tested for 5 times;
test results
TABLE 4
The test result of the third embodiment shows that the test method can test whether the functions of the healthy hand and the affected hand of the patient have significant difference, and provide a basis for judging the functional state for further diagnosis and treatment of the patient.
Example four: evaluation of patient before and after treatment
Patients were divided into two groups: treatment group and control group
The treatment group was trained with the balance test device every day, 2 minutes each time, 5 times a day the control group was trained without the balance test device, and the remaining treatment modes were the same as those of the treatment group;
one week after the intervention, the treatment and control groups were evaluated separately.
The specific test method is the same as the first embodiment, and the test is carried out on the patient for 5 times before and after treatment;
the test results are shown in Table 5, and the time to maintain balance before and after treatment for 5 patients is shown in FIG. 5
Table 5
The test result of the fourth embodiment shows that the exercise of the test device can effectively assist in improving the arm and hand functions of the patient, and particularly, the improvement effect of the test device is more remarkable for the patient with serious upper limb dysfunction.
