There is a global demand to keep larger segments of the population mobile for the preservation of independence and quality of life. Young, healthy adults often take for granted how complicated it is to stably transition in their inside surroundings and the outside environment. In short, we constantly modify our movement patterns in order to smoothly and safely transition between various scenarios. A gait transition is the process of changing from an initial condition to a final condition during walking or running. Examples of these transitions include gait initiation, gait termination, modifications to surface slope, alterations in surface stiffness, changes in direction, and navigation of stairs. The maintenance and precision of mobility is dependent upon the ability to make these gait transitions seamlessly.
Our lab is presently quantifying how young, healthy adults transition between level and sloped surfaces. Concurrently, we are also collecting preliminary data on three populations; aging adults (with or without neural disabilities), pregnant women (prenatal through postnatal), and orthopedic patients (with either deficient or reconstructed knee ligaments). Such information will guide rehabilitation and formulate protocols that have strong potential to increase mobility accuracy.
