Foreign studies have shown that the effect of rehabilitation treatment of brain injury is influenced by many factors, such as the age of the injured person, the pre-morbid level of intelligence, general health, social environment, etiology, the location and extent of lesions, the dominant hemisphere of the patient, the degree of cognitive impairment, patient motivation and emotional response to treatment, etc., which are discussed below. I. Age Some studies have shown that the younger the injured person is, the greater the likelihood of recovery. This may be due to the fact that older patients are more likely to be in a generalized aging stage of brain decline before the disease, and therefore, as the patient ages, the potential for mobilizing brain function decreases. Thus, the expected effect is also to be poor. Second, the pre-morbid intelligence level of patients with high intelligence level before brain injury, can obtain better rehabilitation results, because he or she has more intellectual resources available to rebuild the new functional system. Some studies have shown that the initial level of ability presented after brain injury is consistent with the level that may be reached in the final recovery. Third, general health status and brain integration function The patient’s general health level and brain integration ability are important factors that affect the rehabilitation outcome. Patients with other serious diseases can affect the functional state of the brain and hinder recovery. A comprehensive measurement of brain integration function through certain neuropsychological tests will help in the estimation of disease prognosis. If the results of the assessment indicate that the damage is relatively limited and some basic abilities are not impaired, the prospects for recovery are better. Conversely, if the assessment shows diffuse lesions and extensive impairment of brain function, the prognosis is poor. In conclusion, the prediction of rehabilitation prospects is based on the integrity and potential of the callable brain areas. IV. Social Environment The attitudes and certain reactions of the patient’s family and friends toward the patient and treatment have a significant impact on rehabilitation treatment. Support and encouragement from the family is a valuable aid in the rehabilitation process. Conversely, indifference and negative emotions such as the belief that treatment is hopeless can be a barrier to receiving rehabilitation treatment. Therefore, the social environment, especially the negative influence of relatives, should not be ignored in the rehabilitation process. While administering treatment to the patient, it is important to have a thorough understanding of the patient’s social environment and to provide the necessary counseling and guidance, not only to eliminate resistance, but also to turn resistance into assistance. This is because the participation of relatives who live with the patient in the rehabilitation training often plays a role that medical personnel cannot play. V. Motivation Throughout the rehabilitation process, it is very important for the patient to actively work and cooperate with the treatment, so attention should be paid to mobilizing the patient’s motivation from the beginning to the end. For example: first arrange the rehabilitation procedures and measures that are easy to work early, the surrounding encouragement, the rapport between doctors and patients, etc., all of which can help the rehabilitation treatment. Emotions The emotional problems of brain injury patients is another issue worthy of attention in rehabilitation treatment. It includes: denial of their own illness, depression, aggressive confrontation with treatment staff and family members and other negative emotions. It is extremely important to treat all three – emotional, behavioral and motivational problems – simultaneously. We need both comprehensive consideration and specific analysis of the various conditions of different patients in order to develop a targeted, individualized rehabilitation plan that will maximize the benefits of rehabilitation treatment. VII. Dominant hemispheres Left-handed patients have more opportunities to have bilateral hemispheric dominance, and therefore, more abilities belong to bilateral brain functions. Such patients naturally have more potential for functional recovery and better rehabilitation prospects. The earlier the recovery time from the injury, the more the dysfunction may be caused by secondary effects of the lesion, such as cranial pressure. In this case, the dysfunction has a strong tendency to recover spontaneously. Therefore, if timely and appropriate rehabilitative training is provided, satisfactory results will usually be achieved.
