About
Keisuke Otsuka’s research sits at the intersection of robotics, biomechanics, and occupational health, with a focus on preventing injury in high-risk caregiving environments. His most cited work, “Hamiltonian formulation with reduced variables for flexible multibody systems under linear constraints: Theory and experiment” (2022, 17 citations), advances the mathematical modeling of flexible multibody dynamics—a key contribution for designing more accurate, safer assistive robots and exoskeletons. This theoretical framework enables engineers to simulate complex mechanical systems with reduced computational cost, directly impacting the development of wearable devices. In a more applied vein, Otsuka addresses Japan’s critical shortage of nurses and caregivers—exacerbated by high rates of occupational low back pain. His 2023 study, “Twisting posture detection using triaxial accelerometers to prevent low back pain in nurses and caregivers,” proposes a simple, low-cost method for monitoring harmful twisting motions in real time. By using off-the-shelf accelerometers, the work offers a practical alternative to expensive motion-capture systems, making injury prevention accessible in hospitals and care facilities. Otsuka’s dual focus—bridging rigorous theory with real-world ergonomic solutions—positions him as a researcher who not only advances fundamental mechanics but also directly tackles pressing societal challenges.
