Locomotion outcomes after peripheral nerve injury and repair in cats have been described in the literature for the period immediately following the injury (muscle denervation period) and then again for an ensuing period of long-term recovery (at 3 mo and longer) resulting in muscle self-reinnervation. Little is known about the changes in muscle activity and walking mechanics during midrecovery, i.e.

Design: Before-after trial.
Setting: Biomechanics research laboratory.
Examining gait characteristics in older adults who are transitioning to frailty enhances our understanding of movement control in this fall-prone population and helps to better target preventive interventions. This work presents data on temporal and spatial gait parameters of a group of older adults who have been operationally defined as "transitionally frail". Gait speed, cadence, stride length, stance, swing, double-support, and horizontal heel velocity at heel contact were measured in 50 transitionally frail older adults while walking at a self-selected pace.
