The role of transcutaneous electrical nerve stimulation

Transcutaneous electrical nerve stimulation is mainly used to treat pain caused by various reasons, and can also be used to promote healing after wound surgery. Its frequency is generally in the low frequency range between 2-160 Hz, the pulse should be short or shorter, and the width is generally between 9-350 μm. transcutaneous electrical nerve stimulation A pulse that is too wide activates pain-transmitting fibers and activa tes ions under the motor, which may make pain worse.


The intensity is generally a comfortable intensity, and the afferent nerve response that stimulates proprioception can be selected, and the efferent nerve response that does not trigger movement is mainly used. The current intensity varies in form. Currently, there are dual-current or single-current, bi-directional pulse, and single-wave direction. There is also an asymmetrical bidirectional pulse that can be used with either of these methods.

The concept of embedded computer system

The concept of embedded computer system, in layman's terms, embedded technology is "specialized" computer technology.  embedded computer  ， This special purpose refers to a specific application, such as for network, for communication, for audio, for video, for industrial control, etc. , From an academic point of view, an embedded system is application-centric, based on computer technology, and can be tailored to hardware and software. It is suitable for special-purpose computer systems that have strict requirements on function, reliability, cost, size, and power consumption. Embedded computer system is mainly composed of embedded processor, related supporting hardware, embedded operating system and application software system, etc. It is a "device" that can work independently. Embedded computer generally consists of four parts: embedded microprocessor, peripheral hardware devices, embedded operating system and user's application program. like： What are the f

Benefits of visual fibre wires

As previously noted, fiber optic cabling has a variety of important characteristics that give it a clear edge over classic metal conductor cable connections in many significant standards. Such as: Data transfer rate and info shift - More aged aluminum details cables, normally copper, provide relatively limited data transfer in comparison to nutritional fibre optics. Copper-type conversation cabling was originally created to transfer tone of voice impulses, which don rsquo;t require nearly as a lot data transfer for bulk data move several modern day programs now desire. Speed - Making use of light pulses as the major supply of details conveyance gives fibre optic cabling a huge speed advantage when compared to other methods of information exchange. Dietary fibre will usually far outstrip the envisioned functionality of even substantial-class (Cat5 or Cat6) copper cables in this connection. Distance - In addition to being super quickly, fibre optic cable connections could also hold th

At what age can a child ride a scooter?

Scooter, also known as scooter, is a very common children's sports toy.  3 wheel kick scooter At what age can a child ride a scooter? In fact, whether the child can play or not is suitable for scooter, not only the age. Because safety comes first. The speed of scooters is generally faster. Even if they are old enough, but the development of motor ability is delayed, or the ability to understand is not good, they will still be particularly prone to injury. If you only look at age, you can start playing at the age of 2. That is to say, as long as the child walks steadily and can trot, you can buy a scooter for the child. But be sure to pay attention to safety. like： ​How to choose a baby scooter to be safe? ​Buy a three-wheeled scooter or a two-wheeled scooter? ​How old can play children's scooters
