In the process of helping people with disabilities and patients to obtain rehabilitation, we must first overcome all the psychological barriers that hinder rehabilitation and exclude the interference of some unfavorable factors in order to implement rehabilitation measures and play the role of rehabilitation medical technology. I. The influence of cognitive activities 1. denial. In general, denial is detrimental to the recovery of the disease. For example, some patients with cancer or leukemia often take a chance and doubt whether their examination, fluoroscopy and laboratory report results are switched with those of cancer or leukemia patients due to carelessness of medical personnel, thus not seeking medical treatment in time, delaying their illness and missing the opportunity for possible recovery. In health psychology and rehabilitation medicine, patients’ denial psychology and non-compliance behavior have been included in special research topics. 2. Prejudice. Mostly seen in people with low literacy level and lack of health science knowledge. Their understanding and attitude towards health, health care and rehabilitation are influenced by stereotypical traditional concepts and certain erroneous theories, resulting in many foolish and detrimental behaviors. For example, they refuse surgery, believing that open surgery is painful, requires blood loss, cannot wake up after anesthesia, is often fatal, and has after-effects. Paraplegic patients with urinary retention should have a cystostomy, but because they refuse surgery, the patient eventually dies of uremia. Some are also reluctant to get out of bed and exercise, thinking, “What a germ to be able to get out of bed!” As a result of long-term bed rest, the result caused muscle atrophy of the limbs and a variety of psychological and physical function degeneration. 3. Biased beliefs. Because of the prejudice, it is easy to be partial. Do not believe in the scientific guidance of the physician, but to the charlatan doctors or liars of the “panacea”, “ancestral secret recipes”, witch doctors and the gods of the nonsense and non-medical personnel of the unscientific advice firmly believe; some people do not believe in all, but often hold “The result is that they are duped and delayed in treatment and recovery. 4. Dependence. Due to over-emphasis on their patient role identity, dependence on physicians, nurses and family members can occur. In the process of treatment and rehabilitation, passivity and lack of attention to self-regulation and self-training hinder the exercise of subjective initiative, which is not conducive to timely recovery. 5. Stubbornness. It may be a reflection of personality traits or may be influenced by prejudice, and a few may be influenced by their special status. They insist on their own opinions, think they are right, manipulate doctors, nurses and family members, are fussy, interfere with diagnosis, treatment and rehabilitation programs, and thus often disrupt rehabilitation deployment. These people are often sensitive and suspicious, and once they violate their will, they lose their temper and adopt an uncooperative attitude. 6. Fatalistic view. Some people with disabilities or patients, in the face of misfortune, often have self-pity, self-blame or a sense of guilt, mistakenly believing that illness is fated, the retribution of their ancestors’ lack of virtue, sinful extension of their children and grandchildren, and that they deserve to suffer; some even have low self-esteem, self-blame, and regard themselves as equal citizens, even without the confidence and requirement to seek treatment and rehabilitation. In rehabilitation, it is necessary to get rid of the fatalistic view, cheer up and fight against one’s misfortune in order to facilitate recovery. Second, the influence of emotions The most obvious psychological changes of the disabled and patients are emotional disorders. Due to the disability, mostly accompanied by the destruction of the image, so there is dissatisfaction with self-image, low self-esteem, shame, loneliness, reluctance to participate in social activities, self-isolation, resulting in a sense of emptiness, loneliness, anxiety, depression, pessimism, despair, and even self-abandonment, loss of confidence in recovery, a variety of physical discomfort and pain symptoms. In severe cases of depression, there can be anorexia and light-heartedness. Personality effects The intensity of reaction to frustration, disability and pain, the attitude toward misfortune, and the level of self-evaluation are all related to personality characteristics. People with disabilities or patients with a suspicious personality are sensitive, suspicious, have low tolerance for discomfort and illness, and tend to exaggerate the severity of illness and disability. Lack of confidence in treatment and recovery leads to a delay in the recovery process. People with hysterical personalities are emotionally fragile, extremely unstable in the face of frustration and misfortune, overly cautious about discomfort, stuck to procedures and treatment routines, stubborn, prejudiced, and slightly more changes in treatment procedures, they are suspicious of recovery and shaken in confidence. Fourth, the influence of social factors 1, social attitudes toward people with disabilities. People have different attitudes toward people with disabilities. Sympathy and love will give people with disabilities warmth, support and confidence in recovery; pity, though not malicious, will hurt the self-esteem of people with disabilities and patients; ridicule and insult are mischievous and immoral, which will make people with disabilities and patients feel humiliated, resentful, or self-pitying, which will easily lead to negative emotions and is not conducive to recovery. And abuse and abandonment of disabled children or chronically ill elderly is a crime, which deprives disabled and sick people of the opportunity to recover. 2. Family attitude. The parents, spouses and children of disabled and sick people have an evolutionary process in their attitudes toward them. There are different attitudes at different stages. These different attitudes then have a different impact on rehabilitation. Families with a person with a disability or a patient with a sequelae will have a sense of misfortune for the whole family, accompanied by a sense of guilt. It is believed that the reason why a family member is unfortunate, disabled or has sequelae is because we did not care enough about him/her, did not seek treatment in time, did not take good care of him/her, and missed the opportunity to treat him/her, which caused him/her to suffer from this misfortune. In order to make up for the condemnation of conscience, the disabled and the sick start to take care of them with all kinds of care, no matter how much money they spend, and seek medical treatment everywhere. During this period, it is easy to develop the idea of dependence of the disabled and the sick. If medical treatment is ineffective, some families begin to despair and become discouraged, so much so that a sense of hopelessness and frustration appears. They think: “Forget it, let’s just pretend he’s dead!” Or “It’s like we didn’t have him.” From then on, the family loses confidence in recovery, stops actively seeking recovery, and even adopts an attitude of giving up. Some people even blame the disabled or sick person for all the family’s misfortunes and miseries. The disabled or sick person is used as the scapegoat for the family’s misfortune. In this case, they complain, abuse, and even abandon the disabled and the sick. 3. Attempt to protect personal interests. Some people with disabilities are unwilling to lower the level of disability benefits in order to enjoy long-term benefits and labor insurance. Although they are well and should be discharged, they still exaggerate the discomfort, create new symptoms (i.e., unwilling to give up symptoms), and even resist rehabilitation in order to strive for long-term hospitalization as a way to obtain personal benefits. 4. Social interference. Family members or work units step in to prevent treatment and rehabilitation measures for some motive. Those who should be discharged from the hospital, if they can return to society in a timely manner is conducive to adapt to the environment, to obtain recovery, but the unit and family members are afraid of increasing the burden of reluctance to pick up patients discharged from the hospital. Unbeknownst to them, people with disabilities and patients who should be discharged but cannot are suffering from psychological degeneration due to social deprivation caused by prolonged hospitalization. For those who wish to be discharged, long-term confinement in a hospital is tantamount to a life sentence. As a result, patients become distressed, suffer, deteriorate, and even commit suicide out of despair. 5. Lack of social support system. The level of social support for people with disabilities and patients, the conditions of social insurance, welfare and rehabilitation medical institutions, the availability of sufficient and well-trained rehabilitation medical doctors, rehabilitation psychologists, social workers, and voluntary personnel (or activists) who serve people with disabilities and patients, all affect the sense of security and safety of people in rehabilitation. V. The psychological impact of medical factors 1. The simple and hard attitude of medical personnel; can strengthen the symptoms, make the disabled person anxious and pessimistic, and breed the concept of suspicion. 2, treatment operations are rough, rash or unskilled, increasing the pain that could have been avoided, making patients afraid of surgery, reluctant to inject, etc., forming a psychological resistance in rehabilitation medical treatment. 3.The procedure of drug treatment is complicated and takes too long, and rehabilitation tools are designed to be bulky and uncomfortable to use, all of which can cause patients to give up or interrupt their treatment, so that the result of rehabilitation is not achieved. 4. The side effects of drugs are too great and are not explained to the patient before using them. When the side effects appear, the patient cannot adhere to the treatment because he cannot tolerate them, which affects rehabilitation.
