Evidence of impaired neuromuscular responses in the support leg to a destabilizing swing phase perturbation in hemiparetic gait

B Sharafi, G Hoffmann, AQ Tan, YY Dhaher - Experimental Brain …, 2016 - Springer
The neuromuscular mechanisms that underlie post-stroke impairment in reactive balance
control during gait are not fully understood. Previous research has described altered muscle …

Impairments in the mechanical effectiveness of reactive balance control strategies during walking in people post-stroke

C Liu, JL McNitt-Gray, JM Finley - Frontiers in neurology, 2022 - frontiersin.org
People post-stroke have an increased risk of falls compared to neurotypical individuals,
partly resulting from an inability to generate appropriate reactions to restore balance …

Control of reactive balance adjustments in perturbed human walking: roles of proximal and distal postural muscle activity

PF Tang, MH Woollacott, RKY Chong - Experimental brain research, 1998 - Springer
Studies on the proactive control of gait have shown that proximal (hip/trunk) muscles are the
primary contributors to balance control, while studies on reactive balance control during …

The next step in understanding impaired reactive balance control in people with stroke: the role of defective early automatic postural responses

D de Kam, JMB Roelofs… - … and neural repair, 2017 - journals.sagepub.com
Background and objective. Postural muscle responses are often impaired after stroke. We
aimed to identify the contribution of deficits in very early postural responses to poorer …

Reduced gait stability in high-functioning poststroke individuals

T Krasovsky, A Lamontagne… - Journal of …, 2013 - journals.physiology.org
Falls during walking are a major cause of poststroke injury, and walking faster may decrease
the ability to recover following a gait perturbation. We compared gait stability between high …

Impaired foot-force direction regulation during postural loaded locomotion in individuals poststroke

JN Liang, DA Brown - Journal of neurophysiology, 2013 - journals.physiology.org
Following stroke, hemiparesis results in impaired motor control. Specifically, inappropriate
direction of foot-forces during locomotion has been reported. In our previous study that …

Post-stroke walking behaviors consistent with altered ground reaction force direction control advise new approaches to research and therapy

WL Boehm, KG Gruben - Translational stroke research, 2016 - Springer
Recovery of walking after stroke requires an understanding of how motor control deficits
lead to gait impairment. Traditional therapy focuses on removing specific observable gait …

Paretic versus non-paretic stepping responses following pelvis perturbations in walking chronic-stage stroke survivors

JAM Haarman, M Vlutters, RACM Olde Keizer… - … of neuroengineering and …, 2017 - Springer
Background The effects of a stroke, such as hemiparesis, can severely hamper the ability to
walk and to maintain balance during gait. Providing support to stroke survivors through a …

Single joint perturbation during gait: preserved compensatory response pattern in spinal cord injured subjects

EC Field-Fote, V Dietz - Clinical neurophysiology, 2007 - Elsevier
OBJECTIVE: Responses to afferent input during locomotion are organized at the spinal level
but modulated by supraspinal centers. The study aim was to examine whether supraspinal …

Maintaining sagittal plane balance compromises frontal plane balance during reactive stepping in people post-stroke

TJW Buurke, C Liu, S Park, R den Otter, JM Finley - Clinical Biomechanics, 2020 - Elsevier
Background. Maintaining balance in response to perturbations during walking often requires
the use of corrective responses to keep the center of mass within the base of support. The …
