Susumu Ota, PT, PhD,
Professor

Professional interests

My research interests relate to human musculoskeletal biomechanics. Particularly, my main areas of interest are the prevention of knee osteoarthritis, sport injuries of the lower extremity, and functional disorder in the elderly. In addition, I also collaborate with engineering departments of universities and with companies in the corporate world to create health care products. My knowledge and expertise have been acquired mainly based on my clinical experiences as a physical therapist.
