Description

A method and device for determining a balance capability index

Technical Field

The present invention relates to the field of electronic information technology, and in particular to a method and device for determining a balance capability index.

Background technique

The improvement of personal balance ability is related to the recovery of motor function and daily living activities. In recent years, with the widespread application of computer-assisted technology, various systems for evaluating balance ability have entered clinical use, which can quantitatively and objectively reflect the user's balance function. During use, a comprehensive and reasonable assessment of the user's balance ability is helpful to formulate an appropriate training plan.

In 1986, Tinetti developed the "Balance Status (Gait) Grading Assessment", which scores the subjects in eight items, including sitting, standing, starting standing, standing with eyes closed, extended standing, rotation and sitting down, so as to quantify and grade the balance function (from 0 to 15 points, divided into three states: normal, variant and abnormal). In 1989, Berg developed the "Balance Scale", which scores the subjects based on their completion of five items, including sitting to standing, standing with eyes open on both feet, standing with eyes closed on both feet, standing in a linear step, and turning. The above two scales have been clinically verified to have good reliability and validity.

In addition, in rehabilitation medicine, the Barthel and Fugl-Meyer methods for functional assessment of stroke patients also include items related to balance ability. The Barthel method scores by observing the presence or absence of balance reactions and the quality of postural reactions. The Fugl-Meyer method scores by graded sitting balance and standing balance reactions.

Although these test scales are quantitative in nature, they are somewhat subjective. Therefore, the balance ability indicators obtained based on the above test scales are not accurate enough in measuring the user's balance ability, resulting in limited application value.

The method will be introduced below with reference to the flow chart of the method for determining the balancing capability index shown in FIG. 1 .

Step 101: Perform a first training on a user, and/or perform a second training on the user.

The first training may refer to the training combining attention and balance ability, and the second training may refer to the training combining memory and balance ability.

Optionally, the first training includes visual attention training and/or auditory attention training, the visual attention training includes at least one or more of the following: visual concentration training, visual stability training, visual tracking training, visual width training, visual resolution training, and combined vision and short-term memory training; the auditory attention training includes at least one or more of the following: auditory concentration training, auditory stability training, and combined hearing and short-term memory training.

In a possible implementation, the user may use the balance device for training, and the training may include training combining attention and balance ability, or training combining memory and balance ability, or both of the above training.

Step 102, during the training process, the training score, reaction time and center of gravity position of the user are determined, and the center of gravity position is displayed in real time in the display area.

During the training process, the user's center of gravity data can be collected based on the balance device, and the center of gravity data can be converted into display data, and the relative position of the center of gravity in the display area, that is, the center of gravity position, can be displayed in real time in the display area on the display device. When the user is training, each key time point can be recorded, and the user's reaction time can be calculated accordingly, and the user's training score can also be counted.

Step 103: record the training information triggered during the training process.

The training information may include training scores, average reaction time and center of gravity trajectory.

After the training is finished, the statistical training scores can be recorded, the average of the recorded reaction times can be calculated and the corresponding average reaction time can be recorded, and the center of gravity position displayed in real time can be recorded to obtain the corresponding center of gravity trajectory.

The above-mentioned first training (i.e., the training combining attention and balance ability) can have various forms, and each form is introduced below.

The first form: discrimination training.

The training method can be as follows:

Displaying the first multimedia and non-first multimedia in different areas of the display area multiple times;

Allow the user to control the center of gravity to move in the display area and select any multimedia.

The training score includes a first score, which is used to indicate the number of times the first multimedia is selected, and the reaction time includes a first reaction time, which refers to the time length used to select the multimedia.

Taking visual discrimination training as an example, the multimedia at this time can refer to multimedia that can be displayed, such as characters and pictures. The principle of training is to use the center of gravity to select the specified multimedia.

In a possible implementation, after the training starts, the middle area of the display device can display several pictures and the user's center position at that time, and the right area of the display device can display a specified picture A. At this time, the picture A displayed in the middle area is the above-mentioned first multimedia, and the other pictures are the above-mentioned non-first multimedia.

The user can adjust the body, move the center of gravity to the position of picture A in the middle area, and hold it for 2 seconds. At this time, picture A can be judged to be selected, that is, one training is completed, and the designated picture is successfully selected, and 1 point is added to the record. Similarly, if the center of gravity is moved to the position of other pictures and held for 2 seconds, other pictures are judged to be selected, then one training is also completed, but the designated picture is not selected, and 0 points are recorded. The time taken by the user from the appearance of picture A to the selection of any picture is recorded, that is, the first reaction time.

After the next training session begins, the images displayed in the display device may change, including the images and image positions displayed in the middle area, the designated images displayed in the right area, and the like.

The visual discrimination training may include 10 trainings, and after the training, the average reaction time, training score, center of gravity trajectory and other information are recorded. After obtaining the recorded information, further statistics may be performed to calculate the accuracy of selecting the specified picture (i.e., the first multimedia), and the accuracy may be added to the training information for recording.

Of course, the discrimination training may also have other specific training methods, and this embodiment does not limit the specific training method.

The second form: tracking training.

The training method can be as follows:

Displaying the second multimedia in different areas of the display area multiple times;

The user is allowed to control the center of gravity to move in the display area to select a target area in the second multimedia.

The training score includes a second score, which is used to indicate the number of times the target area is selected, and the reaction time includes a second reaction time, which refers to the length of time used to select the target area.

Taking visual tracking training as an example, the multimedia at this time can refer to multimedia that can be displayed, such as characters and pictures. The principle of training is to use the center of gravity to track the multimedia.

In a possible implementation, after the training begins, a moving target (i.e., the second multimedia) may be displayed on the display device. The user may adjust the body, control the center of gravity, and quickly move to the center of the target (i.e., the target area). After 2 seconds, the target area is determined to be selected, i.e., the tracking is successful, and 1 point is added to the record. The time from the appearance of the target to the successful tracking is recorded, i.e., the second reaction time.

The target can be moved 10 times during the whole training process. After the training, the training information such as the average reaction time, training score and center of gravity trajectory used to track the target are recorded.

Of course, tracking training may also have other specific training methods, which are not limited in this embodiment.

The third form: stability training.

The training method can be as follows:

Playing third multimedia;

The user is allowed to control the center of gravity to move in the display area, following the guidance of the third multimedia.

The training score includes a third score, and the third score is used to indicate the number of successful following instructions. The reaction time includes a third reaction time, and the third reaction time refers to the length of time used to successfully follow the instructions.

The principle of training is to control the center of gravity to move in the same direction or opposite direction to the third multimedia.

Taking visual stability training as an example, multimedia at this time may refer to displayable multimedia such as pictures and video streams.

In a possible implementation, after the training begins, a track can be displayed on the display device, with a number of obstacles (i.e., the third multimedia) distributed in the middle of the track. The user can adjust the body, use the center of gravity to control the car, and avoid obstacles (i.e., follow the instructions to move in the opposite direction). If the avoidance is successful, 1 point is added; if the avoidance fails, 1 point is subtracted. During the entire training process, training information such as the average reaction time, accuracy, and center of gravity trajectory used to avoid obstacles is recorded.

Taking auditory stabilization training as an example, the multimedia at this time can be playable multimedia such as voice and music.

In a possible implementation, after the training begins, the speaker can play voice to guide the user to move the center of gravity in the forward, backward, left, right and other directions. When the center of gravity shifts to the specified direction by a preset distance and persists for 2 seconds, it is determined that the user has successfully followed the guidance and 1 point is added. During the entire training process, the average reaction time, accuracy, center of gravity trajectory and other training information used to successfully follow the guidance are recorded.

Of course, the stability training may also have other specific training methods, which are not limited in this embodiment.

The fourth form: width training.

The training method can be as follows:

Simultaneously displaying a plurality of fourth multimedia in a first order in the display area;

The user is allowed to control the center of gravity to move in the display area, and select a plurality of fourth multimedia according to a first sequence.

Among them, the training score includes a fourth score and a fifth score, the fourth score is used to indicate the length of the reaction time, the fifth score is used to indicate the number of times the multimedia errors are selected, and the reaction time includes a fourth reaction time, and the fourth reaction time refers to the time used to complete the sequential selection.

Taking visual width training as an example, the multimedia at this time may refer to multimedia that can be displayed, such as characters and pictures. The principle of training is to select multimedia in a set order.

In one possible implementation, after the training starts, a 5*5 grid can be displayed in the middle of the display device, and 25 numbers from 1 to 25 are randomly displayed in each grid, and each number appears only once. The user can select numbers in order from small to large, and control the center of gravity to stay on the number for 2 seconds, which is recorded as a successful selection. The user's reaction time to complete from 1 to 25 is recorded, and a score is given based on the reaction time. The longer the time, the lower the score. During the entire training process, the user's reaction time, score, center of gravity trajectory, number of errors, and other training information will be recorded.

Of course, the width training may also have other specific training methods, which are not limited in this embodiment.

The first training may also have other forms, such as visual concentration training, auditory concentration training, visual and short-term memory combined training, auditory and short-term memory combined training, etc. Concentrated training may refer to maintaining concentration while watching or listening to multimedia. For example, the center of gravity may be kept stable at the initial position for 2 seconds, which means that the training is successful, 1 point is added, and the training score, average reaction time, center of gravity trajectory and other training information of the entire training process are recorded. Training combined with short-term memory may refer to short-term memory while watching or listening to multimedia, and corresponding balance ability training, and the training score, average reaction time, center of gravity trajectory and other training information of the entire training process are recorded.

The user may perform any one or more of the above-mentioned first trainings, and this embodiment does not limit the specific training performed by the user.

Similarly, the second training mentioned above (i.e., the training combining memory and balance ability) can also have multiple forms, each of which is introduced below.

The first form: memory capacity training.

The training method can be as follows:

In one display group, a plurality of fifth multimedia are displayed in the display area according to a second order, and the plurality of displays are performed sequentially;

The user is allowed to control the center of gravity to move in the display area and select a plurality of fifth multimedia according to a second sequence.

Among them, the training score includes the sixth score and the seventh score. The sixth score is used to indicate the number of times the multimedia is selected correctly, and the seventh score is used to indicate the number of times the correct selection is completely made in a group of displays. The reaction time includes the fifth reaction time, and the fifth reaction time refers to the time used to complete the sequential selection.

Taking the image capacity training as an example, the multimedia at this time can refer to any image. Taking the character capacity training as an example, the multimedia at this time can refer to any character. The principle of training is to use the center of gravity to select multimedia in order.

In a possible implementation, after the training starts, the display device can display pictures in sequence, and the user can remember the pictures that appear and the order in which they appear. Then, adjust the body and use the center of gravity to select the pictures that appear in order. After a group of pictures are completely selected correctly, 1 point is added. During the entire training process, 10 groups of pictures can be memorized, and training information such as the number of times the user selects correctly, average reaction time, score, center of gravity trajectory, etc. can be recorded.

The same goes for character capacity training, which will not be elaborated here.

Of course, memory capacity training may also have other specific training methods, which are not limited in this embodiment.

The second form: information processing speed training.

The training method can be as follows:

In one display group, a plurality of sixth multimedia are displayed in the display area according to a third order, and the plurality of displays are performed sequentially;

The user is allowed to control the center of gravity to move in the display area, and sequentially select the last two displayed sixth multimedia.

Among them, the training score includes the eighth score and the ninth score. The eighth score is used to indicate the number of times the multimedia is selected correctly, and the ninth score is used to indicate the number of times the correct selection is completely made in a group of displays. The reaction time includes the sixth reaction time, which refers to the time used to complete the sequential selection.

Taking character refresh training as an example, multimedia at this time can refer to any character. Taking picture refresh training as an example, multimedia at this time can refer to any picture. Taking auditory refresh training as an example, multimedia at this time can refer to any audio. The principle of training is to use the center of gravity to select the last two multimedia that appear in order.

In a possible implementation, after the training begins, pictures may appear in sequence on the display device, and the user needs to remember the last two pictures in order. After all the pictures are finished, the last two pictures are selected in order using the center of gravity. If the selection is correct, 1 point is added. During the entire training process, 10 groups of pictures need to be memorized, and training information such as the number of correct recognitions, average reaction time, score, center of gravity trajectory, etc. need to be recorded.

The same goes for character refresh training and auditory refresh training, so I won’t go into details here.

Of course, the information processing speed training may also have other specific training methods, which are not limited in this embodiment.

The user may perform any one or more of the above second trainings, or may perform the first training or the second training alone, or perform the first training and the second training simultaneously. This embodiment does not limit the specific training performed by the user.

Step 104: determining the user's balance ability index based on the training information.

In a possible implementation, the recorded training information can be calculated according to a preset calculation rule to obtain a corresponding balance ability index for measuring the balance ability of the user. For example, the training scores can be weighted averaged, and the higher the training score, the better the balance ability of the user. For another example, the average reaction time can be evaluated, and the shorter the time, the better the balance ability of the user. For another example, the center of gravity trajectory can be evaluated, and the smoother the center of gravity trajectory, the better the balance ability of the user.

Of course, the user's balance ability may also be evaluated based on other calculation rules, which will not be listed one by one in this embodiment.

Optionally, EEG training can be combined to provide brain function training that is close to real life. The corresponding methods can be as follows:

During the training process, the user's EEG is monitored to obtain monitoring results, which are used to indicate the power proportion of multiple EEG bands of the user;

Based on the monitoring results, the user is given EEG training, which includes at least one or more of the following: rest training, attention training, memory training, and sleep training.

In a possible implementation, EEG monitoring can be added during the above training process. EEG monitoring includes the following bands: δ, θ, a, β, γ, and uses the power ratio of the band to measure the user's immediate brain function. By monitoring indicators, appropriate EEG training can be selected.

An example is as follows: If the monitoring results show that δ and θ account for a high proportion, and the user is often sleepy during the day and has poor sleep quality at night, add sleep training. The principle of sleep training is to reduce the δ and θ bands and increase the a band. When the user's two bands have corresponding trend changes, the game screen will move in the positive direction, such as flowers will bloom and cars will run forward; if there is no trend change, the game screen will not move.

EEG training can be implemented based on the principle of operant conditioning in psychology. This embodiment does not introduce the bands adjusted by other training one by one.

The above-mentioned EEG training can be performed simultaneously with the balance ability training, or can be performed separately after the balance ability training is completed, which is not limited in this embodiment.

The beneficial effects that can be obtained by the embodiments of the present invention are as follows:

(1) During the balance training process, attention and/or memory are combined for training, and the corresponding training scores, reaction time and center of gravity position are recorded during the training process. After the training, the user's balance ability is evaluated based on the training score, average reaction time and center of gravity trajectory. Since the training information is obtained based on an objective training process, it has a certain objectivity and can improve the accuracy and reliability of the balance ability index. In addition, combining attention and/or memory for training can also improve the training effect on the user.

(2) By providing users with EEG training that is close to real life and improving their cognitive and balance abilities, the improvement in their quality of life is particularly obvious.
