Brief Biography

Dr. Katherine (Katy) Rudolph is physical therapist and researcher in the Department of Physical Therapy in the Westbrook College of Health Professions at UNE.  She earned an MSPT Boston University in 1989 and a Ph.D. in Biomechanics and Movement Science from the University of Delaware (UD) in 1998.   After post-doctoral training in the Center for Biodynamics at Boston Universitiy she accepted a faculty position at UD where she remained from September, 1999 thru August, 2011.  She joined the UNE family in September, 2011.

Research Interests

Dr. Rudolph’s research interest is neuromuscular control of locomotion and chronic pain. She studies people with joint instability in anterior cruciate ligament deficiency and knee osteoarthritis; people with hemiparesis post-stroke and older adults. She is also interested in developing new technologies for use in rehabilitation including muscle strengthening devices and rehabilitation robots for gait training.
