Easy-Flex Smart is an upper extremity rehabilitation therapy device that provides movement, flexion and extension for fingers and the wrist. Stroke patients or others who may have limited hand function can use Easy-Flex Smart without much help from physical or occupational therapists, because the device is equipped with sensors to guide accurate movements. A mobile app collects data for visual feedback. Designed by: Bong-Keun Jung, Jung-Yeon Kim, Chan-Wan Kim, Hong-Joong Jung and Byeong-Seo Park of WellTech, Soonchunhyang University, RehabsystemContact: Jungyeon Kim
