Description

Technical Field

[0001] The present invention belongs to the technical field of rehabilitation exercise, and particularly relates to a VR-based rehabilitation exercise system for low back pain. Background Art

[0002] Most low back pain is caused by muscle contracture, trauma or spinal deformity. Low back pain may occur at any position on the back from the neck to the waist, which may be a small part or may spread over a large area. With the accelerating pace of society and the increasing work pressure, as well as the improvement of people's living standards and living and working environments, the incidence of low back pain is increasing at an alarming rate, which may be related to factors such as the prolonged desk work time, reduced activities and obesity of people. Low back pain disorders not only exist in mental workers, but also widely exist in manual workers, and are the most common symptoms in clinical practice. Due to the characteristics of difficult treatment, long course of treatment and easy recurrence, low back pain has become an intractable disease that is difficult to cure in modern society, seriously affecting people's quality of life. Therefore, it is very necessary to enhance people's understanding of low back pain disorders, understand the corresponding treatment plans and health care knowledge, so as to achieve the purpose of preventing occurrence, early diagnosis, early treatment and preventing recurrence.

[0003] For low back pain caused by non-systemic diseases, rehabilitation exercise is the best choice. The rehabilitation exercise for patients with low back pain is first to strengthen the exercise of the core muscles of the low back. After the core muscles of the low back are strengthened, good tension is maintained during standing, sitting or sleeping, and a good neutral position of the spine is maintained. During exercise, it can protect and control the spine so as not to exceed the normal flexion and extension range, increase the stability and flexibility of the spine, and reduce waist injuries.

[0004] However, there are the following problems in the current rehabilitation exercise:

[0005] (1) During the exercise process, patients feel pain in the low back, and it is difficult to bear the pain, so it is difficult to persist in training for a long time, and the rehabilitation effect cannot be achieved;

[0006] (2) When patients are exercising, they usually train by referring to videos, etc., without the guidance of professional personnel, and the exercise movements are not standard, affecting the rehabilitation effect of the low back.

[0007] Therefore, a VR-based rehabilitation exercise system for low back pain that can distract patients' attention from pain during exercise and standardize movements is proposed. Summary of the Invention

[0008] To solve the above technical problems, the present invention designs a VR-based lumbar and back pain rehabilitation exercise system, which includes a VR glasses, a motion monitoring module, and a control module. The VR glasses and the motion monitoring module are both connected to the control module. The VR glasses include a lens body, a head fixing strap, earphones, and a signal receiver. The open end of the lens body is connected to the head fixing strap, the head fixing strap is connected to the earphones, and the signal receiver is arranged inside the lens body. The motion monitoring module is composed of a lumbar and back fixing device and a motion tracking sensor installed on the device. The lumbar and back fixing device includes a waist fixing component, a telescopic rod, a back fixing component, and a motion tracking sensor. The bottom of the waist fixing component is connected to the bottom of the telescopic rod, the back fixing component is connected to the top of the telescopic rod, and the motion tracking sensor is connected to the waist fixing component. When performing lumbar and back rehabilitation exercises, wear the lumbar and back fixing device on the user, turn on the motion tracking sensor, and then put on the VR glasses to simulate the exercise scene and actions. The user follows the actions in the scene simulation to exercise. The VR glasses transmit the data of the standard actions to the control module, and the motion tracking sensor transmits the user's action data to the control module. After comparison, the non-standard action data is feedback to the motion tracking sensor and a prompt sound is issued. At the same time, it is feedback to the signal receiver of the VR glasses for re-playing the exercise.

[0037]

[0038] Calculation of the difference in the initial value: initial pain intensity - pain intensity during / after practice. Therefore, a positive value indicates that the pain intensity during / after practice has decreased relative to the initial intensity. 95% CI = 95% confidence interval, M = mean, SD = standard deviation, VR = virtual reality.

[0039] Example 2

[0040] Refer to Figures 1 to 7 As shown, a VR-based lumbar and back pain rehabilitation exercise system includes: VR glasses, a motion monitoring module, and a control module;

[0041] Both the VR glasses and the motion monitoring module are connected to the control module. The motion monitoring module monitors the motion information and transmits it to the control module. The standard motion information simulated by the VR glasses is also transmitted to the control module. The control module processes and compares the information, and feeds back the information of non-standard actions to the motion monitoring module for prompting, and at the same time feeds back to the VR glasses for scene reproduction exercise; The VR glasses include a lens body 1, a head fixing strap 2, earphones 3, and a signal receiver 4. The open end of the lens body 1 is connected to the head fixing strap 2, the head fixing strap 2 is connected to the earphones 3, and the signal receiver 4 is arranged inside the lens body 1; The motion monitoring module is composed of a lumbar and back fixing device and a motion tracking sensor 10 installed on the device. The lumbar and back fixing device includes a waist fixing component, a telescopic rod 7, a back fixing component, and a motion tracking sensor 10. The bottom of the waist fixing component is connected to the bottom of the telescopic rod 7, the back fixing component is connected to the top of the telescopic rod 7, and the motion tracking sensor 10 is connected to the waist fixing component.

[0042] Fix the waist fixing ring 5, waist fixing belt 6, and connecting pad 61 of the lumbar and dorsal fixing device to the user's waist. The connecting pad 61 is facing the exact back of the user's waist. Support the back with the back support block 8. The fuzzy surface 91 of the back fixing belt 9 adheres and fixes to the hook surface 92. The center of the bottom of the waist fixing ring 5 is hinged to the bottom of the telescopic rod 7, and the back support block 8 is hinged to the top of the telescopic rod 7. When the device is worn normally, the telescopic rod 7 fits perfectly with the groove. After the lumbar and dorsal fixing device is fixed, turn on the switch 1001 of the motion tracking sensor 10, wear the VR glasses well through the head fixing belt 2, and start the scene simulation exercise. The exercise scene and actions are simulated and played inside the VR lens body 1, and the user follows to perform lumbar and dorsal exercises. As the user exercises, the distance between the telescopic rod 7 and the groove changes. The standard angle change of the waist and back for this action is 5 - 8 degrees. The user makes an action that changes the distance between the telescopic rod 7 and the groove by 2 cm. The motion tracking sensor 10 collects the 2 cm distance change and transmits it to the single-chip microcomputer. The single-chip microcomputer calculates and converts the data. The angle change of the user's waist and back for this action is 6 degrees, and this action meets the standard, then start the next exercise action; if the angle change of the patient's action is 4 degrees, it is determined that this action does not meet the standard. The single-chip microcomputer feeds back this non-compliant action to the motion tracking sensor 10, and the indicator light 1002 of the motion tracking sensor 10 lights up to indicate that this action is not standard. At the same time, this non-compliant action is fed back to the signal receiver 4 of the VR glasses, and the VR glasses perform a re-simulation of this action scene.

[0043] When performing lumbar and dorsal pain exercises, the standardization of actions can be carried out to achieve more scientific and effective exercises.
