Abstract The aim of this research is to explore a biomedical engineering technique which can rebuild the flexion function of the five fingers of the paralyzed upper limb. Based on the patented concept of electromyographic bridge (EMGB) and combined the Chinese traditional medical skill of acupuncture, this study selects 10 volunteers (five men and five women)and uses small area surface electrodes on upper limb 216 pairs of acupoints of each healthy volunteer for functional electrical stimulation (FES) on skin surface to test the best stimulation sites of five fingers’ flexion. The five pairs of acupoints found for five finger flexion in the experiment. The current threshold is less than 10mA, the success rate of finger flexion is 100%, the purity rate of single finger flexion is over 80%, and the rate of comfort degree is over 90%.Compared with traditional FES, this way needs less current, has higher purity of five finger flexion and has a standard location rule which lays a foundation for clinical trials of patients’ healthy fingers driving paralytic fingers to flex.
