In recent years, with the progress of medical level, the survival rate of high incidence of stroke patients has also been steadily increasing, but about 85% of patients still have hand function impairment sequelae, such as spasm, numbness, muscle weakness, and muscle tension disorder. The recovery of fine motor function such as hand dexterity still has great challenges; the rehabilitation needs of hand function are also increasing. At the same time, for clinical research, in the current practice, major hospitals all assess the damage of patients according to the clinical experience of doctors or their own set of scales, lacking a digital standard assessment and intervention system, especially for the assessment and intervention of fine motor function such as hand dexterity.
