Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training, and specifically to an upper limb rehabilitation training system based on electromyogram signal feedback. Background Art

[0002] In the field of rehabilitation medicine, the restoration of upper limb function is crucial for patients to return to normal life. The upper limb not only undertakes numerous tasks in daily activities, such as grasping objects, writing, dressing, etc., but also is an important limb part for people to interact with the outside world. However, the number of patients with upper limb dysfunction caused by various reasons such as stroke, spinal cord injury, trauma, etc. is on the rise, and there are still many deficiencies in the existing rehabilitation training systems.

[0003] On the one hand, traditional upper limb rehabilitation training mainly relies on the manual operation of rehabilitation therapists and simple instrument assistance. The labor cost is high and it is difficult to ensure the accuracy and consistency of training. The professional level and physical strength differences of therapists will lead to uneven training quality for different patients. For example, when performing joint range of motion training, it is very difficult to ensure that the force and range of motion applied each time are exactly the same. Moreover, manual training has low efficiency and is difficult to meet the rehabilitation needs of a large number of patients. As the number of patients increases, the limited resources of rehabilitation therapists become more and more tense, and it is impossible to provide enough training time for each patient, which to a certain extent affects the rehabilitation process of patients; on the other hand, the rehabilitation needs of upper limb dysfunction caused by different etiologies, such as stroke, trauma, neurological diseases, etc., are significantly different. Even for the same disease, factors such as the age, physical condition, and rehabilitation goals of patients will also make the rehabilitation plan different. However, the existing rehabilitation training systems often lack the function of personalized customization and cannot be adjusted in real time according to the specific situation of patients; in addition, traditional rehabilitation effect evaluation mainly relies on the subjective judgment of doctors and simple scale tests, lacking objective and quantitative data support. This evaluation method has certain limitations and is difficult to accurately reflect the true rehabilitation situation of patients.

[0004] In view of this, the purpose of the present invention is to provide an upper limb rehabilitation training system based on electromyogram signal feedback to solve the deficiencies existing in the prior art. Summary of the Invention

[0017] The present invention provides an upper limb rehabilitation training system based on myoelectric signal feedback. It has the following

[0018] Beneficial effects:

[0019] 1. The present invention collects the training situation of the user through the myoelectric signal acquisition mechanism, and then after being processed by the signal collection device, it is fed back to the feedback display mechanism, enabling the user and medical staff to understand the muscle activity situation in real time. When the myoelectric signal shows that a certain muscle is over-fatigued, the airbag in the massage component automatically inflates or deflates, and at the same time, the vibration motor drives the massage plate and the circular massage block to vibrate, stimulating the muscles and acupoints, promoting blood circulation, effectively relieving muscle fatigue and soreness, improving the rehabilitation effect, and the user can adjust the training state in time according to the feedback, enhancing the scientificity and effectiveness of the training, and assisting the recovery of the upper limb muscle function.

[0020] 2. The present invention drives the first telescopic rod according to the myoelectric signal, thereby driving the support plate to slide on the slider to simulate the flexion and extension movements of the arm. Also, the telescopic column in the auxiliary training component adjusts the height according to the myoelectric signal feedback of the grasping force to assist the user to complete the grasping action. At the same time, the friction is reduced by the balls in the palm groove to exercise the hand flexibility. Finally, the coordinated work of multiple components can not only meet the training of different rehabilitation stages and needs, but also make the training closely fit the actual movement intention of the user, enhancing the pertinence of the training and improving the efficiency of the user's upper limb rehabilitation training.

[0021] 3. The present invention makes flexible adjustments based on the feedback of electromyogram signals. When the electromyogram signals of the user's shoulder muscles show tension or fatigue, the position of the universal wheel moving mechanism is adjusted to align the second massage plate with the part to be massaged. The height of the second massage plate is adjusted by the third telescopic rod to adapt to different users. At the same time, the second massage plate is driven to rotate by the motor, so that the bottom balls reduce the friction with the skin, realizing effective massage of the shoulder. Then, the feedback display mechanism continuously collects and analyzes data, and adjusts the training plan according to the user's rehabilitation progress, which can not only relieve the tension and fatigue of the shoulder muscles, but also ensure the scientific and reasonable nature of the entire rehabilitation training process, improve the applicability of the device, meet the personalized rehabilitation needs of different users, and achieve better rehabilitation effects.

[0033] The flexion and extension component in the training institution 2 includes a base 201 installed in the middle side inside the main frame 1. A seat 202 is installed on the upper part of the base 201. A main body platform 203 is installed beside the base 201. Sliders 204 are installed on both sides of the upper part of the main body platform 203. Chutes 205 are provided on the upper parts of the two sliders 204. Support plates 206 are slidably installed on the upper parts of the two sliders 204. A baffle 208 is installed at one end of the upper part of the main body platform 203. One side of the baffle 208 is connected to one end of the two sliders 204 respectively. Two telescopic rods one 207 are fixedly installed on one side of the baffle 208. The output ends of the two baffles 208 are fixedly connected to one end of the two support plates 206 respectively;

[0034] Specifically, the seat 202 provides a comfortable sitting posture for users, enabling them to carry out rehabilitation training in a relatively relaxed state. The chute 205 enables the support plate 206 to slide on the slider 204. Under the action of the slider 204 and the chute 205, the support plate 206 realizes smooth sliding, thereby driving the user's arm to perform flexion and extension movements. The baffle 208 plays a role in connecting and fixing the slider 204. One side of the baffle 208 is connected to one end of the two sliders 204 respectively, ensuring the synchronism and stability of the slider 204 during the movement process, and driving the support plate 206 to move through the telescopic action, realizing the simulation of the flexion and extension actions of the arm.

[0035] The fixing component includes arm rests 209 respectively installed on the upper parts of the two support plates 206. A plurality of buckles 210 are installed at both ends of the upper parts of the two arm rests 209. Straps 211 are installed between the two corresponding buckles 210;

[0036] Specifically, the shape and size of the arm rest 209 are designed according to the contour of the human arm, which can not only provide comfortable support for the arm, but also keep the arm stable during the training process. The buckle 210 is convenient and fast to operate. Users can adjust it according to the thickness of their own arms. After fixing the strap 211 through the buckle 210, the arm can be tightly fixed to prevent the arm from displacing during the training process, ensuring the safety and effectiveness of the training.

[0037] The massage component includes a plurality of air bags 212 respectively installed on both sides of the inner parts of the two arm rests 209. Massage plates one 213 are installed at the bottoms of the two arm rests 209. A plurality of massage blocks 214 are installed on the upper parts of the two massage plates one 213.

[0038] The shapes of the plurality of massage blocks 214 are all circular;

[0039] Specifically, the airbag 212 is automatically inflated or deflated to squeeze and relax the user's arm. At the same time, the vibration motor 216 drives the first massage plate 213 to vibrate, causing the circular massage blocks 214 on the first massage plate 213 to vibrate accordingly, thereby stimulating the muscles and acupoints of the user's arm and promoting blood circulation.

[0040] The auxiliary training component includes two telescopic columns 217 installed at the other end of the upper part of the main body table 203. A grip rod 218 is fixedly connected between the output ends of the two telescopic columns 217. A placement plate 219 is installed at the other end of the upper part of the main body table 203. Two palm grooves 220 are formed on the upper part of the placement plate 219, and a plurality of first balls 221 are arranged inside the two palm grooves 220.

[0041] Specifically, the telescopic columns 217 automatically adjust the height according to signal feedback to help the user complete the grasping action. The first balls 221 in the palm grooves 220 on the placement plate 219 can reduce the friction between the palm and the placement plate 219.

[0042] The myoelectric signal acquisition mechanism 3 includes a first support frame 301 installed in the middle side of the main frame body 1. A signal collection device 302 is installed at the bottom of the top of the first support frame 301. Two leads 303 are installed at the bottom of the signal collection device 302. One end of each of the two leads 303 is installed with an electrode patch 304, and wristbands 305 are installed at both ends of the two electrode patches 304.

[0043] The myoelectric signal acquisition mechanism 3 is installed on both sides of the training mechanism 2.

[0044] Specifically, the function of the signal collection device 302 is to accurately collect and analyze the myoelectric signals generated by the upper limb muscles of the user. The leads 303 are responsible for transmitting the myoelectric signals collected by the electrode patches 304 to the signal collection device 302. The electrode patches 304 are components that directly contact the user's skin and can effectively collect the weak electrical signals generated by the muscles. The wristbands 305 are used to fix the electrode patches 304 on the user's wrists to ensure that the electrode patches 304 are closely attached to the skin and improve the quality of signal acquisition.

[0045] The feedback display mechanism 4 includes a second support frame 401 installed on one side of the main frame body 1. Two second telescopic rods 402 are installed at the bottom of the top of the second support frame 401. The output ends of the two second telescopic rods 402 are fixedly connected with a display screen 403, and speakers 404 are installed on both sides of the display screen 403.

[0046] Specifically, the telescopic rod two 402 can flexibly adjust the height and angle of the display screen 403 according to the needs and perspectives of the user, facilitating the user's viewing. The display screen 403 is used to display training data and relevant information. The speaker 404 can emit sound prompts, such as the prompts for the start and end of training, providing more comprehensive feedback information for the user.

[0047] The mobile adjustment component in the shoulder rehabilitation mechanism 5 includes a plurality of universal wheels 501 installed on the other side inside the main frame body 1. On the upper parts of two of the universal wheels 501, bottom plates 502 are installed. Between the upper parts of the two bottom plates 502, a support frame three 503 is installed. At the bottom of the top end of the support frame three 503, two telescopic rods three 504 are installed. The output ends of the two telescopic rods three 504 are fixedly connected to a connecting plate 505. At the bottom of the two connecting plates 505, motors 506 are fixedly installed. The output ends of the two motors 506 are fixedly connected to massage plates two 507. At the bottom of the two massage plates two 507, a plurality of balls two 508 are provided.

[0048] The shoulder rehabilitation mechanism 5 is installed on both sides of the seat 202.

[0049] Specifically, the universal wheels 501 facilitate the adjustment of the position to meet the shoulder position requirements of different users. The telescopic rods three 504 can adjust the height of the massage plates two 507 according to the shoulder height of the user, enabling the massage plates two 507 to better fit the shoulders for massage. The connecting plates 505 are used to connect the telescopic rods three 504 and the motors 506. At the bottom of the two massage plates two 507, a plurality of balls two 508 are provided, which can reduce the friction between the massage plates two 507 and the shoulder skin, making the massage process smoother, and at the same time massaging the shoulders during rotation to relieve the tension and fatigue of the shoulder muscles.

[0050] Working principle: First, the user sits on the seat 202 of the training mechanism 2, places the arms on the armrests 209, and then fixes the arms by fastening the straps 211 through the buckles 210 to ensure the stability of the arms during training. At the same time, wear the wristband 305 on the wrist to make the electrode patches 304 closely fit the skin for collecting myoelectric signals.

[0051] When the user performs upper limb movements, muscle contraction will generate weak myoelectric signals. The signals will be captured by the electrode patches 304, and then the electrode patches 304 will transmit the collected myoelectric signals to the signal collection device 302 through the leads 303. At the same time, the signal collection device 302 will perform preprocessing operations such as amplifying and filtering the signals to remove interference signals and improve the signal quality for accurate analysis later.

[0052] The processed electromyogram (EMG) signals are transmitted to the display screen 403 of the feedback display mechanism 4. The display screen 403 will display relevant data such as the intensity and frequency of the EMG signals in real time. Users and medical staff can understand the muscle activity of the user during the training process in real time. At the same time, corresponding reminder sounds can be emitted through the speaker 404. For example, when the intensity of the EMG signal reaches a certain standard, it reminds the user that the training effect is good; or when there are abnormal fluctuations in the EMG signal, a warning sound is emitted to alert the user and medical staff.

[0053] In the training mechanism 2, the EMG signals are also transmitted to the flexion and extension components. When the signal collection device 302 receives the EMG signals of the user wanting to perform arm flexion and extension movements, it will convert the signals into control instructions and send them to the first telescopic rod 207. The first telescopic rod 207 performs telescopic movements through the instructions, thereby driving the support plate 206 to slide on the chute 205 of the slider 204. At the same time, the movement of the support plate 206 simulates the flexion and extension movements of the arm, enabling the user's arm to perform rehabilitation training under the restraint of the fixing component, making the training more in line with the actual movement intention of the user and improving the pertinence and effectiveness of the training.

[0054] When the EMG signals show that a certain muscle of the user is over-fatigued, the airbag 212 automatically inflates or deflates, thereby squeezing and relaxing the massage on the user's arm. At the same time, the vibration motor 216 drives the first massage plate 213 to vibrate, causing the circular massage blocks 214 on the first massage plate 213 to vibrate accordingly, and then stimulating the muscles and acupoints of the user's arm, promoting blood circulation, relieving muscle fatigue and soreness, and further improving the rehabilitation effect.

[0055] When the user holds the grip rod 218 for flexion and extension training, the EMG signals will also be collected and analyzed. When it is detected that the user's grasping force is weak, the telescopic column 217 will automatically adjust the height according to the signal feedback, providing a certain amount of auxiliary force to help the user complete the grasping action. Moreover, the first ball 221 in the palm groove 220 on the placement plate 219 can reduce the friction between the palm and the placement plate 219, making the user's hand movements smoother and also exercising the flexibility of the hand.

[0056] In the shoulder rehabilitation apparatus 5, the movement adjustment component adjusts according to the user's needs and the feedback of the electromyogram signal. When the electromyogram signal of the user's shoulder muscles shows a tense or fatigued state, the position of the shoulder rehabilitation apparatus 5 can be conveniently moved through the universal wheels 501, so that the second massage plate 507 can better align with the part of the shoulder that needs to be massaged. At the same time, the height of the second massage plate 507 can be adjusted through the third telescopic rod 504 to adapt to the shoulder height differences of different users. Finally, the second massage plate 507 is driven to rotate by the motor 506 to realize the massage of the user's shoulder. At the same time, the friction between the second massage plate 507 and the shoulder skin can be reduced through the second ball 508 at the bottom of the second massage plate 507, and the shoulder is massaged during the rotation process, thereby relieving the tension and fatigue of the shoulder muscles and promoting the rehabilitation training of the shoulder.

[0057] During the entire training process, the feedback display mechanism 4 continuously collects and analyzes the electromyogram signal and the movement data of the training mechanism 2 and the shoulder rehabilitation apparatus 5. Through these data, the system can evaluate the user's rehabilitation progress in real time and adjust the training plan. When it is found that the user makes slow progress in a certain training action, the system can automatically increase the training intensity and time of this action; when the user's muscle strength has improved, the system can appropriately increase the training difficulty, such as increasing the resistance of the auxiliary training component, etc., to ensure that the training always meets the user's rehabilitation needs and achieves the best rehabilitation effect.

[0058] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
