A Pilot Study on Evaluating Recovery of the Post-Operative Based on Acceleration and sEMG

Although abdominal operation is a kind of important clinical surgery, recovery of the post-operative is usually evaluated by the judgment of doctors. This traditional medical care mode may take much time of medical staffs and meanwhile increase the expense of patients. In this paper, a recovery evaluation system is established for the abdominal post-operative by using body sensor networks (BSN). The evaluation system can collect acceleration signals from five parts of human body and surface electro myographic (sEMG)signals from abdomen muscle group (AMG) during a user'sdaily activities. An experiment as a pilot study has been conducted to test the validity and feasibility of the system. The experimental results showed the evaluation system may effectively acquire the relationship between a user's daily activities and intensity of AMG. The study work in this paper may be used as a basis for further study on evaluating recovery level of the actual post-operative.
