TL;DR: With the enlargement of the ongoing arm swing, the arms contributed to balance recovery by postponing the transfer of arm angular momentum to the trunk, which resulted in an axial rotation of the lower segments of the body towards the non-tripped side, which increases the length of the recovery step in the sagittal plane, and therefore facilitates braking the impending fall.

TL;DR: Precision demands and mental pressure in aiming and tracking tasks with a computer mouse were found to coincide with increased muscle activity in some upper extremity muscles and increased force exertion on the computer mouse.

TL;DR: A small increase was found in step width and foot clearance due to ankle dorsiflexion, but these changes were not expected to alter the probability of tripping nor the recovery reactions after tripping in an experimental setup.

TL;DR: This matrix, developed by the Consensus for Experimental Design in Electromyography (CEDE) project, presents six approaches to EMG normalization and general considerations for normalization, features that should be reported, definitions, and "pros and cons" of each normalization approach are presented.

TL;DR: The lower rate of development of muscle activation in the support limb of older subjects is likely to reduce the rate of force generation, which can contribute to inadequate recovery responses and falls.
