[Abstract]:
Prosthetic Hand

 

The hand is the most distinctive organ of the human body, and the human hand is the perfect tool that nature can create. At the same time, the rehabilitation of hand amputation is also the most difficult problem in the field of artificial limb rehabilitation, because the function of the hand is obviously superior to that of the lower limbs. Human fingers are very sensitive and can feel vibrations with an amplitude of only 0.00002 mm. There is a long way to go to achieve such an effect. With the development of science and technology, the rehabilitation of hand amputation patients has also improved. At present, there are two main programs for hand prosthetic rehabilitation, decorative and functional. So, how can patients with such prostheses use prosthetic hands flexibly?

 

 

1) Decorative prostheses, generally as long as the residual limb receiving cavity is suitable, the suspension device is no problem, and no training is required, but the first-time installer should learn how to wear it, passively rotate the wrist, and passively change the position of the finger. Those with upper arm amputees should learn to use passively controlled elbow locks.

 

 

 

2) Cable-controlled upper limb prostheses and electric upper limb prostheses (including myoelectric prostheses) are all functional prostheses. The difference is that the former is self-powered while the latter is external power. In order to improve the use function of these prosthetic limbs, proper guidance and training are needed.
