Description
Technical Field
The invention relates to a production design scheme of VR equipment, in particular to a VR device capable of guiding rehabilitation by adjusting display content according to detection data.
Background
Female pelvic floor dysfunction disease is becoming a concern for modern postpartum females. Among them, chronic pelvic pain (Chronic Pelvic Pain, CPP) is a common disease, and nearly 15% of women of childbearing age worldwide suffer from this pain. It is counted that 30% -70% of CPP occurs in association with the musculoskeletal system, and its symptoms are mainly manifested by hypertone of pelvic floor muscles and pain upon palpation. CPPs can affect not only the function of various organ tissues, but also cause impairment of social behavior and family life for patients. However, the current treatment regimen employed for CPP hypertonic symptoms remains one of the clinical difficulties.
Currently, the primary therapeutic principle for patients with hypertonic CPP is to relax the overstressed pelvic floor muscles, and after the pelvic floor muscles have relaxed to some extent, perform pelvic floor rehabilitation Kegel (Kegel) exercises. The common pelvic floor muscle relaxation mode can be used for better sensing the extension and relaxation of the pelvic floor muscle by using the modes of language guidance and vaginal palpation besides the conventional abdominal breathing, manual loosening, biofeedback and the like. Some rehabilitation devices in the prior art comprise a training cushion for pelvic floor rehabilitation and VR glasses, some patents in the prior art relate to acquisition of real-time surface electromyographic signals of pelvic floor muscles, and a power supply device of a pelvic floor rehabilitation training system, and the invention of a pressure sensor in a pelvic floor muscle group training device is also disclosed in patent content.
Surface myoelectricity is a physiological electrical signal generated by collecting muscle contraction and is the result of bioelectricity generated when nerves and muscles are excited. The surface myoelectric signal muscle activity function has certain relativity and is one of the common techniques in the field of the rehabilitation of the neuromuscular diseases at present. However, due to the long-term treatment course often required for pelvic floor rehabilitation and high dependence on medical equipment, patient compliance is greatly reduced.

There is no device for implementing wireless acquisition and real-time wireless transmission of myoelectric probe on the surface of basin bottom. The wireless surface myoelectricity shows better use value, but needs to consider how to apply the wireless surface myoelectricity to pelvic floor muscle rehabilitation training, and meanwhile, the VR equipment system is mainly trained on the pelvic floor muscle, and a targeted relaxation training scene is lacked. How to ensure that the wireless surface myoelectric probe can effectively detect the contraction signal of pelvic floor muscle groups and timely feed back the pelvic floor muscle training information in practical application, and is a technical point worth breaking through in combination with VR technology to realize the purpose of home self rehabilitation of a user and ensure corresponding rehabilitation quality.

The control unit can be a processor, a CPU, a PCB and the like with operation capability, and can only complete potential comparison and send out a control signal. In a further embodiment, whether the myoelectric value to be determined by the control unit meets a first condition is that the myoelectric value belongs to a first myoelectric value interval, whether the myoelectric value to be determined by the control unit meets a second condition is that the myoelectric value belongs to a second myoelectric value interval, and when the myoelectric value is determined to meet the condition, a subsequent step may be performed. The first myoelectricity value interval and the second myoelectricity value interval are specific numerical value ranges, and different numerical values can be set according to different detected specific positions of the focal muscle groups. The first video clip and the second video clip may be videos for guiding the user to perform specific actions, or immersive guiding videos for simulating the actions of a person. According to the technical scheme, the surface myoelectricity probe can detect muscle tension, video content is played according to the detection result of the surface myoelectricity probe, the guiding performance of the muscle group guiding rehabilitation device is improved, a user is immersed in the device and relaxed, and finally the implementation effect of improving user interactivity and interestingness is achieved.

By the adoption of the scheme, the myoelectricity value can be obtained, and the myoelectricity value of the target muscle group can be calculated more scientifically and accurately.
In a further specific embodiment, the control unit is wirelessly connected with the surface myoelectric probe. Specifically, the two can be connected with each other in a centered manner through the wireless communication unit, multiple short-distance communication protocols such as Bluetooth, wiFi and LoRa can be adopted, myoelectricity values collected by the surface myoelectricity probes can be transmitted to the control unit in real time, interference of wires to user operation is reduced, and the user is focused on rehabilitation guidance content, so that the practicability of the application is improved.
