About this episode
Biomechanist Katy Bowman and biologist Jeannette Loram discuss gait and question whether there is a ‘right’ way to walk. They explain the mechanics of walking gait, outlining the phases and shapes that each leg and foot should move through during the gait cycle. They propose that an ‘abnormal’ gait would be one that is missing one of these phases or shapes. They also suggest a framework for assessing walking based on efficiency, symmetry and balance. They talk about gait deficits such as shuffling and waddling and what is missing in those gait patterns while acknowledging that we are all individuals and not all gait variation is abnormal or needs to be corrected. Katy suggests we can only get to the heart of this question by considering human movement ecology; particularly the volume we walk, the shoes we walk in and, for most modern humans, the lack of a requirement to walk long distances efficiently. They discuss this in relation to human hunter-gatherers as well as other animals. Finally, they answer a couple of listener questions on the rather unusual gait seen in racewalking.
