If the influences of aging processes on gait are to be understood, gerontologists must become better versed in experimental methodology appropriate to locomotion research. They must also begin to conduct experiments that move beyond mere description. Systematic research efforts that are interdisciplinary in nature and that incorporate several types of gait analyses will be needed to discover the causes of adaptations and impairments of gait in the aged. Certainly, this will not be easy to accomplish; however, we hope that the work reported here demonstrates this approach is possible and worthwhile.
