About
Tsuyoshi Nakajima is a leading researcher in human motor control and neurophysiology, with a focus on how sensory feedback—particularly load-related and movement-related afferent signals—modulates spinal and corticospinal excitability during locomotion. His work has fundamentally advanced our understanding of the neural mechanisms underlying walking, especially in the context of robotic-assisted passive stepping. Nakajima’s key contributions include demonstrating that cutaneous reflexes in the tibialis anterior muscle are modulated in a phase-dependent manner during passive walking, and that load-related afferent feedback plays a critical role in this modulation (41 citations). He also showed that corticospinal excitability is facilitated during robot-assisted passive stepping (37 citations), and that sensory inputs significantly affect the soleus H-reflex amplitude (34 citations). His research extends to forearm muscles, revealing that rhythmic leg movement suppresses monosynaptic reflexes in distant upper limb muscles (19 citations), with implications for clinical interventions in spasticity after stroke or spinal cord injury. Nakajima’s work has been pivotal in bridging basic neurophysiology with rehabilitation robotics, offering insights that could inform the design of neurorehabilitation therapies.
