Resting state brain network segregation is associated with walking speed and working memory in older adults Open
Older adults exhibit larger individual differences in walking ability and cognitive function than young adults. Characterizing intrinsic brain connectivity differences in older adults across a wide walking performance spectrum may provide …

The control of balance and locomotion Open
We have established that humans use at least three different balance mechanisms to push against the ground to regulate balance during walking. (i) The lateral ankle mechanism activates muscles surrounding the stance leg ankle to pull on th…

Neural correlates of gait adaptation in younger and older adults Open
Mobility decline is a major concern for older adults. A key component of maintaining mobility with advancing age is the ability to learn and adapt to the environment. The split-belt treadmill paradigm is an experimental protocol that tests…

Age differences in adaptation of medial-lateral gait parameters during split-belt treadmill walking Open
The split-belt treadmill (SBT) has been used to examine the adaptation of spatial and temporal gait parameters. Historically, SBT studies have focused on anterior-posterior (AP) spatiotemporal gait parameters because SBT is primarily a per…

Brain activity during walking in older adults: Implications for compensatory versus dysfunctional accounts. Open
A prominent trend in the functional brain imaging literature is that older adults exhibit increased brain activity compared to young adults to perform a given task. This phenomenon has been extensively studied for cognitive tasks, with the…

Flexible Recruitment of Balance Mechanisms to Environmental Constraints During Walking Open
Background: Humans need to actively control their upright posture during walking to avoid loss of balance. We do not have a comprehensive theory for how humans regulate balance during walking, especially in complex environments. The nervou…

Interactions Between Different Age-Related Factors Affecting Balance Control in Walking Open
Maintaining balance during walking is a continuous sensorimotor control problem. Throughout the movement, the central nervous system has to collect sensory data about the current state of the body in space, use this information to detect p…

Interdependence of balance mechanisms during bipedal locomotion Open
Our main interest is to identify how humans maintain upright while walking. Balance during standing and walking is different, primarily due to a gait cycle which the nervous system must contend with a variety of body configurations and fre…

Walking Cadence Affects the Recruitment of the Medial-Lateral Balance Mechanisms Open
We have previously identified three balance mechanisms that young healthy adults use to maintain balance while walking. The three mechanisms are: (1) The lateral ankle mechanism, an active modulation of ankle inversion/eversion in stance; …

Phase-Dependency of Medial-Lateral Balance Responses to Sensory Perturbations During Walking Open
The human body is mechanically unstable during walking. Maintaining upright stability requires constant regulation of muscle force by the central nervous system to push against the ground and move the body mass in the desired way. Activati…

Neural Control of Balance During Walking Open
Neural control of standing balance has been extensively studied. However, most falls occur during walking rather than standing, and findings from standing balance research do not necessarily carry over to walking. This is primarily due to …
