About
Masanori Nagaoka is a leading researcher in biomedical robotics, specializing in assistive technologies for individuals with essential tremor (ET)—a neurological disorder causing involuntary oscillations that severely impair daily activities like eating, drinking, and writing. His core contributions center on developing myoelectric-controlled exoskeletal robots that suppress tremor while preserving natural elbow and forearm movement. Nagaoka pioneered tremor-frequency-based filtering techniques to extract voluntary motion from corrupted EMG signals, enabling more intuitive human-robot interaction. His most influential work, "Development of robotic upper limb orthosis with tremor suppressiblity and elbow joint movability" (2011, 24 citations), established foundational methods for tremor cancellation in wearable robotics. He further advanced the field by designing an elbow-forearm interlock joint mechanism (2014, 14 citations) that supports eating movements, and by analyzing how tremor frequency shifts affect EMG signal processing (2012, 22 citations). Nagaoka’s research directly addresses a critical gap in assistive robotics: creating devices that not only cancel pathological tremor but also recognize and amplify the patient’s intended voluntary actions. His work has profound implications for improving quality of life in ET patients, bridging the gap between neural signal processing and practical rehabilitation engineering.
