11/03-- Shirley Rietdyk, Purdue University professor of health and kinesiology, watches her research team demonstrate how to apply force to 70-year-old Don Corrigan as part of a study to learn how the elderly maintain balance. Josh Williams, a senior in movements and sports science from Evansville, Ind., pushes Corrigan to simulate a loss of balance. Steven Torgerud, a second-year master's student in biomechanics from St. Paul, Minn., stands as a spotter. Mark Knezovich, a first-year master's student in health sciences from Peoria, Ill., monitors Corrigan's reactions on the computer. By studying the interaction between the body's neural and mechanical systems, Rietdyk is learning how the nervous system combines visual and sensory information to coordinate muscle activity.
