DR. Shirley Rietdyk

Research description

Dr. Rietdyk’s research focus is the interaction of the neural and mechanical systems in mobility, posture and balance. In particular, how does the nervous system integrate the visual and sensory information and coordinate the muscle activity to develop safe, balanced and skillful movement? The mechanical system is very unstable with a high center of mass, a small base of support, and three joints in the support limbs. Yet, we move about and interact with the environment with little conscious thought. Disease or aging may lead to delays and degenerations in the balance control system. Can we provide interventions which maintain mobility and quality of life for these individuals?
