[0002] With the continuous increase in the number of aging population in my country, the number of patients with limb dysfunction caused by stroke, brain trauma, upper limb trauma, etc. has increased year by year. The resulting motor dysfunction has brought great misfortune to the patients themselves and a great burden to their families. The society and families need to spend a great deal of money to treat and care for these patients. For those with limb dysfunction, early rehabilitation treatment must be sought, especially rehabilitation treatment within the first three months after the onset of the disease. This is the best time to obtain ideal rehabilitation treatment effects. Early intervention using rehabilitation training plays a positive and effective role in improving the quality of life of patients.
