  • Publication number: 20240071589
    Abstract: The present invention discloses a system and method for redesigning treatment prescriptions according to evaluation of treatment effectiveness. In the present invention, when the system receives the treatment prescriptions from the medical staff terminal, sets the treatment device according to the treatment prescriptions, and delivers the treatment device to the patient, the patient performs treatment by himself using the treatment device at home. When the treatment is finished, the patient terminal transmits the treatment history information, the treatment image obtained by photographing the process of self-treatment, and the questionnaire replies to the system. The system calculates compliance from the treatment history information, evaluates the treatment motor/cognitive/emotional functions from the questionnaire reply, and then provides them to the medical staff terminal together with the questionnaire replies, and allows the medical staff to evaluate effect of the treatment prescriptions.
