Asymmetric gait patterns alter the reactive control of intersegmental coordination patterns in the sagittal plane during walking.

PLoS One 2020 21;15(5):e0224187. Epub 2020 May 21.

Department of Biomedical Engineering, University of Southern California, Los Angeles, CA, United States of America.

Recovery from perturbations during walking is primarily mediated by reactive control strategies that coordinate multiple body segments to maintain balance. Balance control is often impaired in clinical populations who walk with spatiotemporally asymmetric gait, and, as a result, rehabilitation efforts often seek to reduce asymmetries in these populations. Previous work has demonstrated that the presence of spatiotemporal asymmetries during walking does not impair the control of whole-body dynamics during perturbation recovery. Read More

Adaptive trunk sway velocities following repeated perturbations in subjects with and without low back pain.

J Electromyogr Kinesiol 2020 May 1;52:102423. Epub 2020 May 1.

Department of Health Sciences, Central Michigan University, United States.

Faster trunk motions could be a strategy to prevent loss of balance and fall injuries due to unexpected perturbations. However, it is unclear how trunk sway velocities can be compensated during stepping in subjects with low back pain (LBP). The purpose of this study was to investigate lower limb reaction, swing, and step times, as well as trunk sway velocities at heel strike and toe-off, following repeated step perturbations between subjects with and without LBP.

The immediate effects of a shoulder brace on muscle activity and scapular kinematics in subjects with shoulder impingement syndrome and rounded shoulder posture: A randomized crossover design.

Gait Posture 2020 May 4;79:162-169. Epub 2020 May 4.

School and Graduate Institute of Physical Therapy, College of Medicine, National Taiwan University, Taiwan; Division of Physical Therapy, Department of Physical Medicine and Rehabilitation, National Taiwan University Hospital, Taiwan. Electronic address:

Background: Round shoulder posture (RSP) is one of the potential risks for shoulder impingement syndrome (SIS) due to alignment deviation of the scapula. Evidence on how the characteristics of a shoulder brace affecting the degree of RSP, shoulder kinematics, and associated muscle activity during movements is limited.

Research Question: The purposes of this study were (1) to compare the effects of a shoulder brace on clinical RSP measurements, muscle activities and scapular kinematics during arm movements in subjects with shoulder impingement syndrome (SIS) and RSP; and (2) to compare the effects of two configurations (parallel and diagonal) and two tensions (comfortable and forced tension) of the brace straps on muscle activities and scapular kinematics during arm movements in subjects with SIS and RSP.

J Orthop Res 2020 May 15. Epub 2020 May 15.

Rush University Medical Center, Chicago, IL.

The aim of this study was to determine the effect of two in vivo-determined gait patterns, one with low and one with high anteroposterior (AP) motion, on total and backside polyethylene insert wear in comparison with the ISO standard 14243-3. In order to differentiate and accurately quantify topside and backside wear, a novel technique was employed where different lanthanide tracers were incorporated into the polyethylene during manufacture. Wear particle analysis was conducted following established protocols. Read More

Motoric Cognitive Risk Syndrome Using Three-Item Recall Test and Its Associations with Fall-Related Outcomes: The Korean Frailty and Aging Cohort Study.

Int J Environ Res Public Health 2020 May 12;17(10). Epub 2020 May 12.

Elderly Frailty Research Center, Department of Family Medicine, College of Medicine, Kyung Hee University, Seoul 02447, Korea.

Motoric cognitive risk (MCR) syndrome is originally defined as the presence of subjective cognitive complaints (SCCs) and slow gait (SG). MCR is well known to be useful for predicting adverse health outcomes, including falls and dementia. However, around four out of five older Korean adults reported SCCs, thereby, it may not be discriminative to define MCR in Korea. Read More

An Unsupervised Data-Driven Model to Classify Gait Patterns in Children with Cerebral Palsy.

J Clin Med 2020 May 12;9(5). Epub 2020 May 12.

Auckland Bioengineering Institute, University of Auckland, 70 Symonds street, Auckland 1010, New Zealand.

Ankle and foot orthoses are commonly prescribed to children with cerebral palsy (CP). It is unclear whether 3D gait analysis (3DGA) provides sufficient and reliable information for clinicians to be consistent when prescribing orthoses. Data-driven modeling can probe such questions by revealing non-intuitive relationships between variables such as 3DGA parameters and gait outcomes of orthoses use. Read More

Lesser magnitudes of lower extremity variability during terminal swing characterizes walking patterns in children with autism.

Clin Biomech (Bristol, Avon) 2020 May 7;76:105031. Epub 2020 May 7.

Department of Kinesiology and Nutrition Sciences, University of Nevada, Las Vegas, NV, USA.

Background: Anecdotally, children with Autism Spectrum Disorder have highly variable lower extremity walking patterns, yet, this has not been sufficiently quantified. As such, the purpose of this study was to examine walking pattern variability by way of lower extremity coordination and spatio-temporal characteristics in children with autism compared with individuals with typical development during over-ground walking.

Methods: Bilateral continuous relative phase variability was computed for the thigh-leg, leg-foot, and thigh-foot segment couples for 11 children with autism and 9 children with typical development at each gait sub-phase. Read More
