About

Katsuhiko Torii is a leading researcher in assistive and rehabilitative robotics, with a primary focus on improving mobility and safety for elderly and disabled populations. His work centers on developing intelligent prosthetic and transfer-assist devices to prevent falls and enhance quality of life. Torii’s major contributions include the design of a retractor-type robotic knee prosthesis that dynamically adjusts to real-time gait patterns, reducing fall risk for transfemoral amputees. He also pioneered the Lateral Transfer Assist Robot (LTAR), a proof-of-concept prototype that significantly decreases the difficulty of lateral transfers for post-stroke hemiparesis patients compared to traditional wheelchairs. His research has garnered over 30 citations across key papers, with notable studies on maintaining knee flexion posture to prevent trips. Torii’s innovations address critical gaps in elderly care, where rising amputation rates due to arteriosclerosis and diabetes demand safer, adaptive solutions. His work stands out for its practical, patient-centered design, directly tackling the high fall risk that limits prosthesis adoption. By combining real-time gait analysis with robotic control, Torii is advancing a new generation of prosthetics that promise greater independence and safety for users.
