1 Introduction to hand rehabilitation therapy The hand is a motor organ and is most vulnerable to trauma in life and labor, and its incidence accounts for more than one-third of the total number of trauma After trauma, the remaining dysfunction is closely related to the degree of the type of trauma, such as: cutting injury, the cut surface is neater, and the remaining dysfunction is lighter after early repair; while pressure smash, avulsion, and crushing contusion, although the wound is repaired by debridement, the wound still remains serious disability after healing. The dysfunction after hand trauma is the motor and sensory dysfunction caused by scar contracture, tendon adhesion, swelling, joint stiffness, muscle atrophy, tissue loss, and long-term wound non-healing. Therefore, the importance of hand rehabilitation has been emphasized in Europe and the United States since the late 1960s, and there are physiotherapists and therapists specializing in hand therapy. They participate in hand surgery clinical work and carry out rehabilitation of patients before and after surgery, becoming an indispensable component of hand surgery. Due to the early intervention of rehabilitation, the surgical results and functional recovery of patients with hand trauma have been significantly improved, and great economic and social benefits have been achieved. 1977, the duties of hand therapists were legally defined in the U.S. In 1978, the Hand Therapists Association was established, stipulating that full members must be physical therapists and occupational therapists who have been engaged in hand rehabilitation for more than three years. Since then, hand rehabilitation has made great progress, and the profession of rehabilitation medicine has gradually formed in practice. Hand surgery is a discipline that applies surgical diagnosis and treatment to study traumatic diseases and deformities of the hand, and surgery is the main method. Hand rehabilitation is a discipline that studies the causes of hand dysfunction, prevention and treatment, and how to restore or compensate hand function on the basis of hand surgery consultation and treatment. Proficient medicine has permeated the entire hand surgery clinic, from injury to pre- and post-surgery, from tissue healing to functional recovery, from vocational training to social reintegration, all require rehabilitation. Changchun Orthopaedic Hospital Microsurgery Shi Hongcheng 2 hand rehabilitation components and work procedures hand rehabilitation includes disability prevention, hand function assessment and rehabilitation treatment three parts. 2 .1 disability prevention according to the WHO expert technical report, prevention should be carried out in three levels. Primary prevention: is to prevent the occurrence of injury or disease; secondary prevention: is to prevent the occurrence of permanent disability when injury or disease has already occurred, i.e. to prevent injury or disease from becoming disability; tertiary prevention: after the occurrence of mild disability or deficiency, active treatment to limit its development and avoid the occurrence of permanent and severe disability. 2.2 Hand function assessment 2.2.1 Assessment is the basis of rehabilitation treatment Without assessment, it is impossible to plan treatment and evaluate treatment. Assessment is different from diagnosis and is much more detailed and detailed than diagnosis. Since the object of rehabilitation medicine is the disabled person and his or her dysfunction, and the purpose is to maximize the recovery of his or her function, rehabilitation assessment is not to find the cause and diagnosis of the disease, but to objectively and accurately assess the nature, location, scope, severity, prognosis and regression of hand dysfunction, so as to lay the foundation for rehabilitation treatment. The assessment can be done with instruments or without complex instruments in some cases. The assessment should be done at least once before, during and after the treatment. Based on the assessment results, the treatment plan should be developed and modified to make an objective evaluation of the effect of rehabilitation treatment. 2.2.2 Assessment of hand function Appearance and morphology: Through visual examination, palpation and the patient’s movements, the examiner’s knowledge and experience should be used to assess the overall sensation of the hand, including the integrity, movement and sensation of the upper limb and hand, and the presence of mange and deformity. Bone joints are evaluated by X-ray; motor function is evaluated: the muscle strength of the hand and upper extremity is examined by using a freehand muscle strength test and a grip strength meter; the active and passive range of motion of the joints is measured by a goniometer; hand dexterity and coordination/functionality tests are performed. There are many methods of assessment, such as nine-hole column test and Mober pick-up test, etc.; sensory function assessment: measuring various sensory functions of the hand: superficial sensation (pain, touch, temperature), deep sensation (vibration, position, motion), compound sensation (two-point discrimination, coarse, slippery, texture, shape, weight discrimination); electrophysiological function examination: including electrodiagnosis, electromyography, etc. 2.3 Rehabilitation Treatment is formulated according to the site and degree of impairment determined by the assessment. A complete rehabilitation treatment plan should integrate and coordinate the use of various therapeutic tools. The following treatment methods are commonly used in hand rehabilitation: 2.3.1 Physiotherapy It has good effect on inflammation, pain, edema, spasm and local blood circulation disorder. 2.3.2 Exercise therapy It is a method to gradually restore the function of the injured hand by selecting some targeted operations from daily life activities, manual labor or cultural and sports activities that can restore the function and skills of the injured hand and allowing the patient to train according to the requirements. 2.3.2 Exercise therapy It is a method to gradually restore the function of the injured hand by selecting some targeted operations from daily life activities, manual labor or cultural and sports activities that can restore the function of the injured hand. 2.3.3 Hand splints The purpose of using splints is mainly to maintain a certain position of the limb, or to follow the movement of the part of the system, or to prevent the correction of deformity. 2.3.4 Psychological counseling and treatment The biological, psychological and social model of modern medicine points out that people are in a complex social life and interpersonal discourse in the struggle with nature, which is bound to produce certain psychological conflicts and emotional and behavioral disorders at the same time. These psychological and behavioral disorders in turn affect people’s body, life and work. Sickness, injury and disability can be a huge blow to the body and mind, producing a series of psychological disorders, such as pessimism, depression, low self-esteem, and even suicidal thoughts. Psychological rehabilitation is an important element of comprehensive recovery. Psychotherapy is a treatment method for emotional problems and is carried out by specially trained personnel. Understanding the patient’s psychological state, providing targeted treatment, facilitating the patient’s adaptation to the reality of the situation, and encouraging and enhancing the maintenance of the patient’s self-esteem and self-worth. 2.4 Hand rehabilitation work procedures Can be expressed graphically: “Functional assessment a setting of predicted goals a development of a treatment plan a implementation of treatment repeatedly assessed.
