Adornment sex artificial limb, want residual limb to accept cavity only commonly appropriate, suspension device is no problem, do not need training, but should learn to wear a method to the person that installs for the first time, passive rotate wrist, the method that changes finger position passively. For upper arm amputees, they should learn to use passively controlled elbow locks.
Cable controlled upper limb prosthesis and electric upper limb prosthesis (including electromyographic prosthetic hand) are functional prosthetic hands, which differ in that the former is their own power and the latter is external power. In order to improve the function of these prosthetic limbs, proper instruction and training are needed.
One, take off artificial limb training
The residual limb is first put into the receiving cavity before the prosthesis is connected to the shoulder strap.
Second, prosthetic manipulation training
Open and close hand training: rope controlled prosthesis open hand is to rely on the shoulders to force forward bending, not hard when the artificial hand closed by elastic force. Upper arm rope control prosthetic hand must be followed by locking the elbow joint to open the hand. Forearm electromyographic prosthetic hands are often used by amputees to do phantom limb movements. Force the hand to open, extend the wrist to control the open hand, force on one's fingers, and bend the wrist to control the closed hand.
The function of the human hand is a complex sensory feedback and a process of muscle coordination. If the function of the prosthetic hand is really required to have practical value, it must be carefully used for training.
