Humans are strikingly adept at manipulating complex objects, from tying shoelaces to
cracking a bullwhip. These motor skills have highly nonlinear interactive dynamics that defy …

Healthy aging modifies neuromuscular control of dynamic balance. Challenging tasks could
amplify such modifications, providing clinical insights. We examined the effects of age and …

Whole-body angular momentum (WBAM) represents the cancellations of angular momenta
that are produced during a reciprocal gait pattern. WBAM is sensitive to small changes and …

Detection of changes in dynamic balance could help identify older adults at fall risk. Walking
on a narrow beam with its width, cognitive load, and arm position manipulated could be an …

Locomotion on the narrow and compliant supports of the arboreal environment is inherently
precarious. Previous studies have identified a host of morphological and behavioral …

Principles from human-human physical interaction may be necessary to design more
intuitive and seamless robotic devices to aid human movement. Previous studies have …

Multiple strategies may be used when counteracting loss of balance during walking. Placing
the foot onto a new location is not efficient when walking speed is very low. Instead medio …

The back handspring step out (BHS) is a foundational skill in gymnastics balance beam
routines that requires the generation of significant sagittal plane angular momentum while …

Maintaining balance while walking on a narrow beam is a challenging motor task. One
important factor is that the foot's ability to exert torque on the support surface is limited by the …

Background: Dynamic balance keeps the vertical projection of the center of mass within the
base of support while walking. Dynamic balance tests are used to predict the risks of falls …
