The prosthesis mainly plays the role of compensatory function, which can make patients basically take care of themselves in daily life. When the patient's own psychological state is in trouble, it will also have an impact on the use of the prosthesis. First, let's talk about the changes in the mentality that amputees may have before they are fitted with a prosthesis. The first is to feel shocked, and when the results of the amputation are learned, the patient's initial reaction is basically shock. It is difficult to accept reality, there are crying, noisy and other behaviors. The language will be more extreme, and gradually turn into depression.
 
They are unwilling to face the amputation and thinking that everything that happened is just a nightmare, after waking up, it will return to normal. Depressive reaction stage: bad emotions, loss of confidence, thinking that they have become a burden on the family, in some serious situation one may have thoughts of suicide.
 
Acknowledging the adaptation stage: After adjusting the above three mental problems, the patient begins to gradually accept and admit the fact that the limb has been amputated, and will gradually begin to look for a solution to the problem. There are also poor mental adjustments, and the family does not notice the patient's change of mentality, which may lead to the patient's self-abandonment.  
Family members and technicians should always pay attention to changes in the patient's state of mind. For patients who are ready to install a prosthesis or are in the process of fitting a prosthesis, the patient has not completely emerged from the psychological environment of despair and disbelief of facts at this time. Technicians and families should enlighten patients, so that they believe in the progress of society and the development of science and technology, so that patients can accept the installation of prosthetics, cooperate with rehabilitation training, and let patients rekindle the hope of life.
How the above psychological rehabilitation effect will have a certain impact on the patient when assembling the prosthesis, if the patient's mentality is not good, there may be a refusal to assemble the prosthesis or do not cooperate with the installation. Psychological rehabilitation is especially important for the disabled, doctors, family members and people from all walks of life should carry forward the humanitarian spirit, actively care for the mental health problems of the disabled, help the disabled understand themselves, mobilize positive factors, so that their abilities can be fully exerted, and finally return to society smoothly.
