What are the functions and uses of smart prosthetic myoelectric hands Many upper limb amputation patients choose smart myoelectric hands when choosing to install upper limb prostheses. However, after a closer understanding of the patients, we found that most upper limb amputation patients have more or less misunderstandings about smart myoelectric hands. In their opinion, after installing the smart EMG, they should be able to eat, type on the computer, and complete other life actions.   In recent years, with the advancement of science and technology, the technology of the prosthesis industry is constantly updated. New technologies for controlling prostheses through brainwaves in the laboratory have also emerged. However, most of the smart myoelectric hands on the market currently have only three devices. Functional fingers. In order to achieve the effects of various successful assembly cases seen in the eyes of many patients, in addition to choosing a suitable smart myoelectric hand, it also requires a scientific and complete rehabilitation training process.   Statistics show that most patients with upper limb amputation will install smart myoelectric hands to control upper limb prostheses.   But not all patients can realize the installation? 1. The length of the amputation. Because the structure of the smart myoelectric hand itself has a small induction "computer", the smart myoelectric hand itself has a minimum length limit, so the installation of the smart myoelectric hand has requirements for the amputation part and the length of the residual limb. The generally required length is from the wrist joint to the shoulder breaking. This is also a key factor in which type of upper limb prosthesis is installed.   2. Whether the muscle function of the residual limb is normal.   Since the electromyographic prosthesis uses the electromyographic signal generated by collecting the muscle activity of the residual limb as the control source, the body of the residual limb must have the following two basic conditions to install the electromechanical prosthesis:   1. The EMG signal must be large enough to be captured by the sensor normally;   2. The muscle of the residual limb as the signal source can generate the correct EMG signal under the intention of the amputee.   After amputation, often move the residual limb, or consciously exercise the muscle strength of the residual limb, and the signal sensitivity of the body will be stronger. Therefore, it is necessary to consciously exercise the muscles of the lower residual limbs before installing the smart myoelectric hand. In addition, strengthening the residual limbs can effectively avoid the disuse atrophy and joint stiffness of the residual limbs.   Through exercise and rehabilitation, most patients can freely control the smart myoelectric hand.
