The following description of the use of prosthetic training is to accept the cavity and the residual limb fit well and the prosthesis itself is no problem. Decorative prostheses generally do not require training as long as the residual limb is properly adapted to the receiving cavity and the straps are suitable for use, but first-time installers should learn how to put on the prosthesis and teach patients the most basic methods of putting on and using the passive wrist rotation and hand opening and closing of the prosthesis. However, the upper arm amputee should learn to use the passive control of the elbow joint lock. The difference between these two types of prostheses is that the former is self-powered and the latter is externally powered. In order to improve the function of these prosthetic hands need the correct use of guidance and training. 1, put on and take off the prosthesis training: put on the residual limb into the receiving cavity first, and then put on the healthy limb into the shoulder belt, take off the reverse order. 2, prosthetic manipulation training open and closed hand training: for example, the cable-controlled prosthesis open hand is to rely on the shoulders to force forward flexion, not force when the prosthetic hand closed by elasticity. Forearm electromyography prosthesis relies on the forearm muscles of the flexor and extensor to touch the sensor, the signal through the sensor so that the hand can open and close. Elbow flexion, locking elbow, open elbow lock training: cable-controlled upper arm prosthesis, generally using double shoulder abduction, lifting, lowering action control can lock the elbow joint, when the residual side of the shoulder flexion, extension for control can make the elbow passively free flexion and extension. Some cable control hand comes with friction rotation wrist, pin flexion wrist mechanism, can be adjusted to the desired position. The choice of the main hand: normal human hands, the use of primary and secondary, most people are dominated by the right hand (also known as the right hand). After the amputation of the upper limb, if it is unilateral, the main hand after amputation can only be the healthy hand, the prosthetic hand can only do auxiliary hand. Prosthetic use training content should be mainly to train both hands with the movement. If it is a double arm amputation should choose the residual limb condition is better, the side of the prosthesis function better as the main hand. Actual use training: First of all, the amputee is trained to be familiar with the prosthesis and prosthesis control system. Then the first training hand part of the opening and closing action. First on the workbench to do simple opening and closing movements of daily life training, and then practice increasing the level of height change movements until the patient skilled. Training the opening and closing movements of the hand device also starts with the simplest and easiest objects to hold and slowly works up to proficiency. When patients are familiar with these two important basic training processes, they can be taught how to make their residual limbs work well with the prosthesis for practical training so as to achieve the most basic actions of life such as dressing and undressing, personal hygiene (washing, urination and defecation, bathing), eating and drinking, opening and closing doors, switching appliances, cooking, writing with pens, making phone calls, etc., and then transition to study and work training. Upper limb prosthesis training is not too difficult for unilateral amputees, but it is more difficult for bilateral amputees. Since the function of upper limb prosthesis is still relatively simple, amputees need to train hard to adapt to the needs. For two-handed amputation of patients in the assembly of prosthetic hands at the same time to choose the appropriate self-help appliances: such as double upper arm amputee commonly used life sleeve, can be set on the residual limb, and then stuck on a spoon or pen, can eat or write; eat with prosthetic hands can not use chopsticks, can only use the spoon or fork bent into the right angle; combing hair with a thick handle comb, pay attention to the cooperation of both hands; use prosthetic hands to take things from the clothes pocket can first use one hand to key The best thing is to use the left hand to take the right pocket, and the right hand to take the left pocket. Appropriate changes in the items used: such as the use of items on the zipper with a large pull ring, with a false hand can be pulled open; sewn on the clothes Velcro to avoid the trouble of tying the button; use elastic mouth shoes can be used without laces and so on.
