Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a method for evaluating a patient's standing balance ability based on an Internet hospital. Background Art

[0002] With the aging of the population, the problem of decreased balance ability due to age or disease is becoming more and more serious. Accurately assessing the balance ability of patients and providing personalized rehabilitation suggestions have become important research directions in the fields of medicine and rehabilitation. At present, the assessment scale is the Berg balance scale, but the existing technology has shortcomings in application, as follows: The current Berg balance scale assessment method is highly subjective. Different assessors have large differences in their scores for the same patient, resulting in inconsistent assessment results. A single assessment is easily affected by the patient's temporary state and is difficult to fully reflect the patient's balance ability. The safety of the environment and equipment during the assessment process was not fully guaranteed, which posed a risk of patients falling or getting injured. In addition, the nervousness of patients during the assessment process was not given enough attention, which affected the authenticity of the assessment results. The Berg Balance Scale mainly evaluates static balance ability, lacks the assessment of the patient's balance ability in a dynamic environment, and cannot fully reflect the patient's balance status in daily activities. The evaluation results are not comprehensive enough. Traditional manual recording and data processing methods are prone to errors, low data processing efficiency, and difficult comprehensive analysis, which affects the accuracy of evaluation results and the scientific nature of rehabilitation decisions; The assessment method lacks systematicity and specificity, and is unable to provide patients with scientific and personalized rehabilitation advice, resulting in unsatisfactory results of the rehabilitation plan.

[0003] Therefore, those skilled in the art provide a method for evaluating a patient's standing balance ability based on an Internet hospital to solve the problems raised in the above background technology. Summary of the invention

[0021] The present invention is described in detail below in conjunction with the accompanying drawings: Example: Please see attached Figure 1 The embodiment of the present invention provides a method for evaluating a patient's standing balance ability based on an Internet hospital, comprising the following steps: S1. Collect the patient's basic information, including age, gender, medical history, etc., and ensure that the environment is safe, flat and free of obstacles; S2. Explain the purpose and steps of the assessment, communicate well with the patient, and relieve his or her nervousness; S3. Assessment according to Berg balance scale: a.

Use electronic record and data management systems to automatically record and analyze assessment data; S7. Create a relaxed and supportive environment during the assessment process and communicate well with the patient; S8. Based on the comprehensive results of the Berg Balance Scale, comprehensively assess the patient's balance ability to provide personalized rehabilitation advice, develop a regular assessment plan, and track the patient's rehabilitation progress.

[0022] S1 By understanding the patient's basic information, it can provide the necessary background information for evaluation and treatment, and ensure the safety and effectiveness of the evaluation; S2 Enhance the patient's understanding and cooperation, which helps to obtain more accurate evaluation results; S3 Use standardized scoring guidelines and demonstration videos to ensure the consistency and accuracy of the evaluation. Through detailed scoring, the patient's static balance ability can be fully understood; S4 Through multi-faceted evaluation (static and dynamic), the patient's balance ability can be fully understood; S5 Through long-term tracking, the changing trend of the patient's balance ability can be observed, providing a basis for formulating personalized rehabilitation plans; S6 Improve the efficiency and accuracy of data recording and analysis, reduce human errors, and facilitate long-term data management and trend analysis; S7 Improve the patient's psychological state, enhance his confidence, and contribute to more accurate evaluation results; S8 Through comprehensive analysis, it can comprehensively evaluate the patient's balance ability, provide personalized rehabilitation suggestions, and improve rehabilitation effects. Regular evaluation and tracking can adjust the rehabilitation plan in time to ensure the continuity and effectiveness of rehabilitation.

[0023] In step S3, the Berg balance scale is assessed as follows: Sit to stand: ask the patient to stand up from a sitting position to assess their ability to stand independently; stand without support: assess the time the patient can stand without support; stand with eyes closed: ask the patient to stand with eyes closed to assess their balance ability; stand on toes: ask the patient to stand on toes to assess their stability; stand on one leg: ask the patient to stand on one leg to assess their single-leg balance ability; reach out and touch: ask the patient to stand and reach out to touch a designated object to assess their dynamic balance; rotate: ask the patient to rotate 360 ​​degrees on the spot to assess his or her balance ability during the rotation.

[0024] Sit-to-stand test assesses the strength and coordination of the patient's lower limbs, which is very important for daily life activities. Independent completion of this action indicates that the patient's leg muscle strength is good and the coordination is high; unsupported standing test tests the patient's static balance ability. Long-term unsupported standing indicates that the patient's balance ability is good and can maintain stability without external support; standing with eyes closed eliminates visual assistance and mainly relies on the vestibular system and proprioception to maintain balance. This test can detect potential problems with visual dependence and the vestibular system; toe standing tests the strength and coordination of the patient's calf muscles and ankle joints. The ability to stand on tiptoes stably indicates that the patient has strong lower limb strength and coordination; single-leg standing assesses the patient's unilateral balance ability and lower limb muscle strength. Unstable single-leg standing indicates potential risk of falling and imbalance in lower limb strength; reaching and touching tests the patient's balance ability when moving the body's center of gravity. Good dynamic balance ability indicates that the patient can move and operate stably in daily activities; rotation tests the patient's vestibular function and dynamic balance ability. The ability to smoothly complete the rotation indicates that the patient's vestibular system functions normally and can maintain balance during the rotation.

[0025] In step S3, standardized scoring guidelines and demonstration videos are used to assist in the implementation of the assessment: The first step is to provide detailed scoring criteria and explanatory documents. The scoring criteria for each assessment item should be clear and avoid vague descriptions. The second step is that the scoring manual contains the scoring criteria and scoring examples for each item. The third step is to conduct systematic training for assessors so that they can master the scoring criteria and methods. The fourth step is to record standardized demonstration videos to show the correct way to complete each assessment item and examples of different scoring levels. The fifth step is to establish a demonstration video library containing videos for each assessment item. The video library should be easy to access and can be stored and shared online. The sixth step is to use demonstration videos for teaching during the training of assessors to help assessors understand and master the scoring criteria.

[0026] The first step is that detailed scoring criteria can help evaluators accurately understand the scoring requirements of each project, reduce errors in subjective judgment, and improve the objectivity and consistency of the evaluation; the second step is that the scoring manual serves as a reference material to help evaluators accurately implement the scoring criteria in actual operations, provide a consistent evaluation benchmark, and facilitate comparison and reference; the third step is systematic training to ensure that evaluators can correctly understand and implement the scoring criteria, reduce the variability of evaluation results, and improve the reliability and effectiveness of the evaluation; the fourth step is that the demonstration video can intuitively display the scoring criteria and operating steps to help evaluators understand and master the evaluation methods; the fifth step is that the online storage and sharing of the video library facilitates evaluators to consult and learn, and improves the convenience and flexibility of training and actual operations; the sixth step is that through video teaching, evaluators can intuitively understand the scoring criteria and operating methods, which helps to improve the training effect and ensure that evaluators can accurately and consistently conduct evaluations.

[0027] In step S4, based on the center of gravity offset coordinate algorithm, its function expression is: , ,in, is the force on the i sensor, and is the position coordinate of the sensor, is the center of gravity offset in the x direction, is the center of gravity offset in the y direction; in step S4, based on the center of gravity trajectory length algorithm, its function expression is: , where N is the number of sampling points; in step S4, based on the stability index algorithm, its function expression is: ,in, is the average value of the center of gravity position; in step S5, it is used to record, analyze and synthesize multiple evaluation results to form a comprehensive balance ability evaluation report. The algorithm formula is as follows: Score summary formula: The Berg balance scale score for each assessment can be expressed as , where i represents the i-th evaluation: ,in, Represents the score of the jth item in the i-th evaluation; the average score of multiple evaluations: the average score of multiple evaluations It is expressed as: , where N is the number of evaluations; standard deviation: used to measure the degree of dispersion of the score, standard deviation formula: ; Trend analysis: Use linear regression to analyze the trend of score changes over time. Assuming that it represents the time point of the i-th assessment, linear regression can be performed using the following formula: , where a and b are the regression intercept and slope, which can be obtained by the least squares method: , ,in, is the average value of the time points: ; Change rate: Evaluate the change rate of each evaluation score : , where i>1, represents the percentage change of the score of each evaluation relative to the previous evaluation.

[0028] The scoring summary formula summarizes the scores of each assessment and provides the overall results of each assessment. It can quickly understand the overall situation of each assessment and provide basic data for subsequent analysis; the average score of multiple assessments is used to calculate the average score of multiple assessments to reflect the overall balance ability. The average score can provide a general evaluation of the patient's overall balance ability, which is helpful for long-term observation and trend analysis; the standard deviation is used to measure the degree of dispersion of the scores of each assessment. The standard deviation can reflect the fluctuation of the scores. Small fluctuations indicate that the assessment results are stable, while large fluctuations require further analysis of the reasons; the trend analysis function uses linear regression to analyze the trend of score changes over time and identify the upward or downward trend of scores. It can help identify the changing trend of patients' balance ability and provide a basis for adjusting the rehabilitation plan; the rate of change function calculates the percentage change of each assessment score and quantifies the score change. The rate of change can reflect the degree of improvement or regression between each assessment and help monitor the progress of rehabilitation.
