Influence of texting while walking on lower extremity gait function in young adults Hum. Mov. Sci. (IF 1.6) Pub Date : 2024-08-29 Katelyn E. Conroy, Heather R. Vanderhoof, William J. Travis, Alyssa G. Moreno, Jeffrey D. Eggleston
Texting while walking (TWW) is a dual-task activity that young adults perform in their everyday lives. TWW has been reported to affect gait characteristics such as gait speed, stride length, and cadence. However, the influence of TWW on lower extremity gait function has not been investigated. Therefore, the purpose of this study was to quantify gait function by examining gait symmetry and using a time

When individuals stand, they sway and so have to maintain their balance. It is generally expected that task performance is worse when standing and swaying than when sitting and therefore not swaying. In contrast, we hypothesized that greater sway is associated with better task performance in the absence of external perturbations of posture. Twenty-four healthy, young adults performed two goal-directed

Sustained submaximal isometric wrist flexion and wrist extension contractions uniquely impair maximal voluntary contraction force in the antagonist wrist action Hum. Mov. Sci. (IF 1.6) Pub Date : 2024-08-12 Jeff S. Schrattner, David H. Imeson, Davis A. Forman
When fatigued, the wrist extensors, which are the primary wrist stabilizers, impair distal upper limb motor performance in a surprisingly similar way as when fatiguing the wrist flexors. It is possible that the wrist extensors are so active as antagonists that they develop an equal degree of fatigue during wrist flexion contractions, making it difficult to truly isolate their impact on performance

Humans frequently prepare for agile movements by decreasing stability. This facilitates transitions between movements but increases vulnerability to external disruptions. Therefore, humans might weigh the risk of disruption against the gain in agility and scale their stability to the likelihood of having to perform an agility-demanding action. We used the theory of motor synergies to investigate how

This study tested the effects of combining two bandwidth knowledge of performance (KP) on a complex sports motor skill. Twenty-two elementary students were divided into combined wide and narrow bandwidth KP (WNG) and control group (CG). The task was the volleyball serve, whose goal was to hit the bull's eye center of a target lying on the floor on the opposite side of the court. The study was composed

Visual cue spatial context affects performance of anticipatory postural adjustments Hum. Mov. Sci. (IF 1.6) Pub Date : 2024-03-25 Jenna Pitman, Julia Shannon, Michael J. MacLellan, Lori Ann Vallis
Past research indicates that anticipatory postural adjustment (APA) errors may be due to the incorrect selection of responses to visual stimuli. In the current study we used the Simon task as a methodological tool to challenge the response selection stage of processing by presenting visual cues with conflicting spatial context; in this case generating a step response to a left pointing arrow which

Joint kinematics and SPM analysis of gait in children with and without Down syndrome Hum. Mov. Sci. (IF 1.6) Pub Date : 2024-03-23 Matthew Beerse, Kaylee Larsen, Tasnuva Alam, Amy Talboy, Jianhua Wu
Individuals with Down syndrome (DS) walk with altered gait patterns compared to their typically developing (TD) peers. While walking at faster speeds and with external ankle load, preadolescents with DS demonstrate spatiotemporal and kinetic improvements. However, evidence of joint kinematic adjustments is unknown, which is imperative for targeted rehabilitation design. How does increasing walking

The effect of inherent and incidental constraints on bimanual force control in simulated Martian gravity Hum. Mov. Sci. (IF 1.6) Pub Date : 2024-03-21 Yiyu Wang, Osmar P. Neto, Madison Weinrich, Renee Abbott, Ana Diaz-Artiles, Deanna M. Kennedy
The ability to coordinate actions between the limbs is important for many operationally relevant tasks associated with space exploration. A future milestone in space exploration is sending humans to Mars. Therefore, an experiment was designed to examine the influence of inherent and incidental constraints on the stability characteristics associated with the bimanual control of force in simulated Martian
