Occupational therapy is a therapy to improve the physical and mental functions of patients by purposefully and purposefully selecting assignments from daily living activities, occupational work, and recreational activities and training patients to improve their physical functions. It is the application of purposeful, selected work activities to treat and train patients with physical, mental, or developmental dysfunction or disability, resulting in varying degrees of loss of self-care and occupational past abilities, so that they can recover, improve, and enhance their ability to live, learn, and work, and lead a meaningful life as a member of the family and society. Occupational therapy focuses on helping patients recover or achieve a normal, healthy, and meaningful lifestyle and abilities. It is suitable for the rehabilitation of diseases such as sequelae of cerebrovascular accidents, senile cognitive decompensation, mental retardation, Parkinson’s syndrome; sequelae of bone and joint injuries, joint diseases, spinal cord injuries, and cerebral palsy. In our office, we use work tools such as finger muscle strength device, manual power car, cognitive toys, wooden eraser board, abrasive board, etc. Depending on the specific conditions of the patient, we design targeted work programs for rehabilitation treatment, so as to enhance the patient’s manual dexterity, strengthen eye-hand coordination, motor control and working ability, and ultimately improve and enhance the patient’s daily living ability. Indications for occupational therapy The indications for occupational therapy are very broad. Anyone who needs to improve the motor function of the hand (especially the ability to perform activities of daily living and labor), the perceptual function of the body, the cognitive function and the emotional and psychological state, and who needs to adapt to the conditions of housing, occupation and social life, is suitable for training with occupational therapy.

Neurological diseases: stroke, traumatic brain injury, spinal cord injury, degenerative diseases of the central nervous system, Parkinson’s disease, senile dementia, peripheral nerve disorders, etc. Internal diseases: rheumatoid arthritis, osteoarthrosis, coronary heart disease, myocardial infarction, diabetes mellitus.
