Effects of unexpected underfoot perturbations during turning on measures of mediolateral stability and corresponding recovery strategies

Tyler K. Ho, Nicholas Kreter, Cameron B. Jensen, Junseop Son et autres

Humans regularly walk across uneven terrain, which demands reactive control strategies to maintain forward progress and stability. While reactive control during walking has been well described during straight gait, it is unclear how reactive control differs during turning gait. Because turning is …

Bases for the selection of alternate foot placement during straight- and turning-gait

Nicholas Kreter, Peter C. Fino

Humans typically plan foot placement strategy multiple steps in advance when walking across complex terrain. Planning steps in advance is beneficial for both upright stability and forward progress, but one drawback is that new obstacles can make planned foot placement location unsafe …

Behavioural risk models explain locomotor and balance changes when walking at virtual heights

Nooshin Seddighi, Nicholas J. Woo, J. A. Montoya, Nicholas Kreter et autres

Walking in daily life requires humans to adapt to environments that can influence one's fear of falling and anxiety about a potential fall. In such environments, individuals may adopt compensatory locomotor and balance changes to maintain a constant expected risk function equal …

Effects of Unexpected Underfoot Perturbations During Turning on Measures of Mediolateral Stability and Corresponding Recovery Strategies

Nicholas Kreter, Cameron B. Jensen, Paula Kramer, Peter C. Fino

ABSTRACT Humans regularly walk across uneven terrain, which demands the use of reactive control strategies to maintain forward progress and stability. While reactive control during walking has been well described during straight gait, it is unclear how reactive control differs during turning …

Sensory modality of initiation cues modulates action goal-relevant neural representations

Nicholas Kreter, Neil M. Dundon, Jolinda Smith, Michelle Marneweck

The ability to produce goal-directed movement relies on the integration of diverse sensory cues which contribute to goal subtasks, such as trajectory planning and initiation. To achieve these subtasks, the central nervous system must flexibly weight sensory contributions depending on task context, …

Sensory context of initiation-cue modulates action goal-relevant neural representations

Nicholas Kreter, Neil M. Dundon, Jolinda Smith, Michelle Marneweck

Abstract The ability to produce goal-directed movement relies on the integration of diverse sources of sensory information specific to the task goal. Neural representations of goal-relevant features, such as target location and gaze direction, have been well studied in sensorimotor areas. It …

The Effect of Intranasal Plus Transcranial Photobiomodulation on Neuromuscular Control in Individuals with Repetitive Head Acceleration Events

Paula Johnson, Peter C. Fino, Elisabeth A. Wilde, Elizabeth S Hovenden et autres

Objective: This proof-of-concept study was to investigate the relationship between photobiomodulation (PBM) and neuromuscular control. Background: The effects of concussion and repetitive head acceleration events (RHAEs) are associated with decreased motor control and balance. Simultaneous intranasal and transcranial PBM (itPBM) is emerging …

Consequences of changing planned foot placement on balance control and forward progress

Nicholas Kreter, Peter C. Fino

While walking humans generally plan foot placement two steps in advance. However, it is often necessary to rapidly alter foot placement position just before stepping due to the appearance of a new obstacle. While humans are quite capable of rapidly altering foot …
