Abstract
The study of human walking involves the collection and analysis of data describing
body movement during ambulation. From this data, temporospatial gait parameters
can be derived as quantitative values that collectively describe gait. These parameters
are often used to identify gait pathologies, strategize intervention, and monitor efficacy
of treatment. Successful clinical gait analysis depends on normative data that represents
everyday walking ability. Existing normative data sets, however, are restricted
primarily to linear paths, while natural gait mandates curvilinear paths and frequent
changes in direction. Curvilinear paths have been shown to introduce changes in gait
parameters unrelated to pathology. This study aims to identify changes in gait parameters
during curvilinear walking, and quantify these changes as a function of path
radius. A more detailed understanding of this relationship will help improve the diagnosis
of gait pathologies and offer insight into the additional biomechanical demands
of curved-path walking.
