Approaching Process in Walking through an Aperture for Individuals with Stroke
J Mot Behav. 2023 Dec 4:1-11. doi: 10.1080/00222895.2023.2280259. Online ahead of print.ABSTRACTMuroi et al. show that individuals with stroke have improved collision avoidance behavior when passing through an aperture while entering from the paretic-side of the body. However, the underlying mechanism remains unknown. We reanalyzed Muroi et al.'s data to reveal how individuals with stroke walk through an aperture by examining changes in walking velocity and behavioral complexity (i.e., sample entropy, an index of (ir)regularity of time series, regarded lower entropy as more regular and less complex) by focusing on the appr...

Temporal and Spatial Accuracy of Reaching Movements do not Improve Off-line
J Mot Behav. 2023 Nov 26:1-12. doi: 10.1080/00222895.2023.2284786. Online ahead of print.ABSTRACTConsolidation has been associated with performance gains without additional practice (i.e., off-line learning). However, the movement characteristics improving off-line remain poorly understood. To investigate this question, participants were trained to produce a sequence of planar reaching movements toward four different visual targets. The training session with feedback required them to learn the relative time of the movements, the total movement time and aim accurately at each target. The retention test was performed either ...

Accuracy of Force Generation and Preparatory Prefrontal Oxygenation in Ballistic Hand Power and Precision Grips
J Mot Behav. 2023 Nov 23:1-15. doi: 10.1080/00222895.2023.2283541. Online ahead of print.ABSTRACTIt remains unclear whether accurate motor performance and cortical activation differ among grasping forms across several force levels. In the present study, a ballistic target force matching task (20%, 40%, 60%, and 80% of maximum voluntary force) with power grip, side pinch, and pulp pinch was utilized to explore the accuracy of the forces generated as well as the muscular activity of intrinsic and extrinsic hand muscles. By using near-infrared spectroscopy, we also examined bilateral dorsolateral prefrontal cortex (DLPFC) act...
