Description

Technical Field

[0001] The present invention relates to the technical field of scoliosis monitoring, and in particular to a wearable scoliosis rehabilitation monitoring system. Background Art

[0002] Adolescent idiopathic scoliosis (AIS) is a common three-dimensional spinal deformity that primarily occurs in adolescents aged 10-18 years. It is characterized by a spinal Cobb angle greater than 10°, accompanied by impaired postural control and abnormal growth and development. Without timely intervention, mild to moderate AIS (Cobb angle 10°-40°) can progress to severe (Cobb angle >40°), leading to chest deformity, impaired cardiopulmonary function (e.g., a 20%-30% decrease in vital capacity), abnormal appearance, and psychological health issues (e.g., low self-esteem and anxiety). Therefore, early screening, dynamic monitoring, and conservative treatment are crucial for controlling the progression of AIS.

[0003] Currently, the diagnosis and treatment technologies of AIS mainly include the following categories:

[0004] Traditional methods rely on physical examinations, such as the Adams flexion test combined with measurement of the ATR (Axis Trunk Rotation) angle, and X-rays to confirm the Cobb angle. Screening is typically performed in schools or medical facilities, using tools such as the Scoliometer to measure the ATR and determine whether further imaging is needed.

[0005] Problem: Screening coverage is low, especially in small and medium-sized cities and rural areas, where there is a lack of systematic screening programs. Although X-ray examinations are accurate, their frequent use poses radiation risks to adolescents (approximately 0.1-0.2 mSv each time) and cannot be monitored in real time, resulting in an early detection rate of less than 30%.

[0006] Current monitoring techniques: Regular X-ray examinations (every 3-6 months) are the primary method for monitoring AIS progression, combined with brace wear to assess treatment efficacy. Additionally, some studies have attempted to monitor spinal morphology using surface electromyography or optical scanning.

[0007] Problem: X-ray review frequency is limited and cannot capture daily posture changes or short-term progress; sEMG and Moiré equipment are expensive (approximately 50,000 to 100,000 yuan), complex to operate, and mostly static measurements, making them unsuitable for home or school use and difficult to achieve dynamic, continuous monitoring.

[0008] Non-surgical treatment: Suitable for mild to moderate AIS with a Cobb angle of 10°-40°, it includes bracing (such as the Boston brace, worn 20 hours daily), exercise therapy (such as the Schroth method, yoga), and physical therapy. Studies have shown that bracing can slow the progression of scoliosis by 40%-60%, and exercise therapy has a modest effect on mild cases (reducing the Cobb angle by approximately 2°-5°).

[0009] Surgical treatment: When the Cobb angle is >40°, minimally invasive spinal surgery (such as posterior fusion) is recommended, and the correction rate can reach 70%-80%.

[0010] Problem: The brace treatment has poor compliance (the wearing rate among adolescents is <50%), low comfort, and requires regular adjustments, and is expensive (approximately 10,000 to 20,000 yuan).

[0011] Exercise therapy lacks standardized programs and real-time feedback, and its effects vary among individuals, making it difficult to quantify and evaluate.

[0012] The surgery has high risks (infection rate of about 2%-5%, risk of nerve damage of about 1%), and a long postoperative recovery period (6-12 months), which has a greater physical and mental impact on underage patients.

[0013] In recent years, wearable technology has rapidly developed in the field of health monitoring, such as smart bracelets for heart rate monitoring (accuracy ±5bpm) and wearable posture correctors for cervical spine protection. However, current wearable devices still have significant limitations for AIS monitoring and rehabilitation:

[0014] Technological gap: There is a lack of dynamic monitoring equipment specifically for AIS on the market. Existing posture correctors (such as LumoLift) only detect shoulder tilt and cannot measure Cobb angle or ATR, and their functions are limited.

[0015] Insufficient data: Existing equipment cannot provide continuous three-dimensional spinal data (such as coronal, sagittal, and transverse planes), and lacks personalized guidance combined with rehabilitation training.

[0016] Application limitations: Existing research (such as wearable electromyography systems) is mostly at the laboratory stage. The equipment is large (weight > 200g) and has high power consumption (battery life < 8 hours), making it unsuitable for daily wear.

[0017] Therefore, there is an urgent need for a wearable scoliosis rehabilitation monitoring system to solve the above problems. Summary of the Invention

[0033] If 5°<θ Cobb ≤10°, it is judged as mild scoliosis and observation is recommended;

[0034] If 10°<θ Cobb ≤20°, exercise therapy intervention is recommended;

[0035] If θ Cobb >20°, an alarm will sound to prompt medical attention.

[0036] As a preferred technical solution of the present invention, the rehabilitation auxiliary module includes a micro vibrator and a voice prompt unit, which triggers feedback when a bad posture is detected. The judgment conditions for bad posture are:

[0037] |θ tilt |>θ threshold or |ATR|>ATR threshold

[0038] Among them, θ tilt The spinal inclination angle calculated by the acceleration sensor, in degrees; θ threshold is the tilt angle threshold, in degrees; ATR is the trunk rotation angle, in degrees, threshold is the ATR threshold, in degrees.

[0039] As a preferred technical solution of the present invention, the wearable sensor module is made of a flexible bonding material.

[0040] As a preferred technical solution of the present invention, the data processing and transmission unit supports cloud data storage and calculates the development trend of spinal deformity using the following formula:

[0043] As a preferred technical solution of the present invention, the mobile terminal application supports multi-user authority management, allowing parents, schools and doctors to view monitoring data and evaluate the rehabilitation effect using the following formula:

For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0052] Figure 14 is a system block diagram of a wearable scoliosis rehabilitation monitoring system in an embodiment of the present invention. DETAILED DESCRIPTION

[0053] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0054] The following is combined with Figure 1 , the specific implementation methods of the present invention are described in detail.

[0055] The invention proposes a wearable scoliosis rehabilitation monitoring system for early screening, dynamic monitoring and rehabilitation intervention of adolescent idiopathic scoliosis, including:

[0056] The hardware components of the wearable sensor module include: Flexible angle sensor: It uses a resistive flexible sensor (such as FlexSensor2.2) with a sensitivity of 0.1° and a measurement range of -90° to 90°, which is used to detect the coronal plane angle.

[0057] Accelerometer: A three-axis accelerometer (such as MPU-6050) with a range of ±2g and a resolution of 0.01g is used to measure the sagittal thoracolumbar curvature.

[0058] Gyroscope: Same as the MPU-6050 module, with a range of ±250° / s and a resolution of 0.008° / s, used to detect cross-sectional rotation.

[0059] The 12 sensor units are arranged along the spine, specifically at key vertebrae such as T1, T4, T7, T10, T12, L1, L3, and L5. The size of each unit is 10mm×20mm×3mm, and the total weight is approximately 45g.

[0060] The sensor is fixed on a flexible silicone base (3mm thick) and connected by a retractable nylon strap. The spacing can be adjusted from 5 to 10 cm and is suitable for users with a height of 120 to 180 cm. The outer layer is covered with breathable fabric and weighs less than 50g, making it comfortable to wear for a long time. It is used to collect real-time three-dimensional spinal data, including the coronal Cobb angle (θ cobb ), sagittal curvature and transverse rotation angle ATR, sampling frequency 10Hz.

[0061] The data processing and transmission unit includes: Microprocessor: STM32F407 chip, main frequency 168MHz, integrated floating-point unit. Communication module: Bluetooth 5.0 chip (nRF52832), transmission distance 10m, rate 1Mbps.

[0062] The data processing flow is as follows: Raw data acquisition: The sensor outputs angle, acceleration and angular velocity data at a frequency of 10 Hz.

[0063] Filter the data: Use the Kalman filter algorithm to optimize the data. The formula is:

[0064]

[0065] in The current angle estimate, such as θ cobb ; Prediction value, recursively derived from the previous state. k : sensor measurement value; K k : Kalman gain, calculated by the covariance matrix, typical value is 0.1-0.5; H: observation matrix, set to 1, the angle error is reduced to ±0.5° after filtering.

[0066] Then calculate the parameters: Cobb angle:

[0067] Where Δy, Δx: calculated by the coordinates of the maximum angle difference between T1-T12, unit is mm. For example, if the Y coordinate offset at T7 is 10mm and the X coordinate is 50mm, then θ Cobb ≈11.46°.

[0068] where ω z (t): angular velocity of the gyroscope along the Z axis, t0 = 0 s, t1 = 1 s. Use numerical integration (trapezoidal method) with a step size of 0.1 s.

[0069] Finally, trend analysis: where t n -t0: monitoring period (unit: day), such as 7 days, θ Cobb The change value of .

[0070] Data transmission: Packet data per second (including θ cobb , ATR), transmit it to the mobile phone via Bluetooth, and upload it to the cloud (Alibaba Cloud Storage) simultaneously.

[0071] Mobile terminal application (APP) development environment: based on Android / iOS platform, using Flutter framework.

[0072] The functional modules of the mobile terminal application (APP) include: real-time curve display θ Cobb and (ATR), refresh rate 1H, then perform threshold judgment; the threshold judgment is specifically: 5°<θ Cobb ≤10°: prompt "mild scoliosis, please observe regularly";

[0073] 10°<θ Cobb ≤20°: Daily yoga training is recommended;

[0074] θ Cobb >20°: A pop-up alert appears: "Seek medical advice."

[0075] The rehabilitation guidance of the mobile terminal application (APP) includes: Cobb and (ATR) to generate a training plan. For example, if θ Cobb =15°, ATR=8°, recommended: Cat-Cow pose: 10 minutes, 4 sets, 10 times each set; Side plank: 15 minutes, 3 minutes each side.

[0076] Action videos (MP4 format) and timers are also available.

[0077] Effect evaluation:

[0078] Data recording: θ before and after intervention Cobb , such as from 15° to 11°, E = 26.67%.

[0079] Permission management: There are three levels of users: parents (view data), schools (batch management), and doctors (diagnostic recommendations). The data involved in permission management is encrypted using the AES-256 algorithm.

[0080] The rehabilitation assistance module includes: a micro vibrator: installed at the T7 and L3 positions; a voice module: an ISD1820 chip, which stores a 5-second voice message "Please adjust your posture."

[0081] The working mechanism is to first perform posture detection: where θ tilt : Accelerometer calculates the tilt angle, formula: a x is the X-axis acceleration (unit: m / s2), g = 9.8 m / s 2 Then feedback is given based on the threshold value: θ threshold =15°, ATR threshold =10°. Feedback trigger: If θ tilt >15° or ATR>10° for 30 seconds, the vibrator is activated for 3 seconds, and a voice message is played once, saying "Please adjust your posture."

[0082] Self-calibration function: Implementation steps: Start calibration mode every 7 days, the user stands for 5 minutes, and collects 100 θ Cobb , and then calculate the deviation: where x i :ith time θ cobb , N=100.

[0083] Example: If x=10°, x i The mean is 10.2°, so δ = 0.2°.

[0084] This is then corrected: subsequent measurements are subtracted from δ.

[0085] Implementation steps: The user puts the device on the back, adjusts the position from T1 to L5, fixes the nylon strap, turns on the power (3.7V lithium battery, capacity 500mAh), and connects the APP to Bluetooth. At this time, data collection is carried out, the sensor is activated, and the microprocessor calculates θ Cobb and (ATR), the app displays results, recommends training, the rehabilitation module provides posture feedback, records data weekly, evaluates results after 6 weeks, and calibrates regularly.

[0086] Example 1: School screening application;

[0087] In a middle school in Jiaojiang District, Taizhou City, 50 students aged 12-16 were screened for scoliosis for 5 days.

[0088] The device includes: 10 sensor module units (T1, T4, T7, T10, T12, L1, L2, L3, L4, L5); lithium battery; and an app installed on the teacher's mobile phone.

[0089] Implementation process:

[0090] 1. Students wear devices for continuous monitoring during class (8:00-12:00).

[0091] Example: Student A (14 years old, female): The coordinate shift at T7 is Δy=12mm, Δx=50mm.

[0092]

[0093] (ATR):ω z (t) average 0.6% / s, integrated for 1s to obtain ATR = 0.6°.

[0094] 2. Data processing: Kalman filter: initial noise 0.8°, after filtering θ Cobb =13.45°(error±0.5°), APP judgment: 10°<θ Cobb ≤20° indicates "mild scoliosis, exercise intervention is recommended."

[0095] 3. Feedback: Student A sits in an inclined position (θ tilt =18°) for more than 30 seconds, the vibrator is triggered for 3 seconds and a voice prompt "Please adjust your posture" is given.

[0096] 4. Results: Within 5 days, 6 students θ Cobb >10° (positive rate 12%), of which 2 patients exceeded 15°, and the APP recommended X-ray examination to parents.

[0097] Data trend: Student A's θ on the 5th day Cobb =13.60°,

[0098] Technical verification: high screening accuracy, self-calibration δ=0.1°, and stable system.

[0099] Example 2: Rehabilitation intervention trial;

[0100] 10 students diagnosed with mild AIS (θ Cobb 10°-20°), aged 13-15 years, 6-week intervention trial.

[0101] Grouping: Experimental group (5 people): use this system + yoga. Control group (5 people): yoga only, no feedback.

[0102] Device Configuration: Experimental Group: 12 sensors, including two vibrators (T7 and L3), voice module, 48-hour battery life. App: Daily training plan with videos.

[0103] Implementation process:

[0104] 1. Experimental group: Student B (13 years old, male):

[0105] initial: ATR = 7.8°;

[0106] Training: 30 minutes daily, cat-cow pose (10 minutes, 4 sets, 12 reps each, 0.5 Hz), side plank (10 minutes each side);

[0107] Feedback: θ tilt =17°, vibrate for 3 seconds, trigger 120 times in 6 weeks, after 6 weeks: Development Trends:

[0108] 2. Control group: Student C (14 years old, female): Initial:

[0109] Training: Same as above, no feedback; 6 weeks later: E=12.03%

[0110] Results: The average E in the experimental group was 24.8%, while that in the control group was 11.9%, with significant difference (P<0.05).

[0111] This specific implementation method includes detailed hardware design (such as 12 flexible sensor units and an STM32F407 microprocessor), algorithm implementation (such as Kalman filtering and Cobb angle calculation), and a complete operational process (from wearing to effect evaluation). Example 1 verifies the high accuracy and portability of the system in school screening, and Example 2 demonstrates its significant effect in rehabilitation intervention (the improvement rate in the experimental group increased by about one-fold), proving the practical value and promotion potential of the system in early monitoring and conservative treatment of AIS.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
