Wistar rats were trained to retrieve a sunflower seed from a horizontal tube using a forelimb. Animals which demonstrated motor asymmetry were selected, and their training conditions were changed. The horizontal tube was replaces by that with a slot in the bottom in such a way that improperly seized seeds dropped out of the tube. Dynamic reorganization of motor coordination under these changed conditions was investigated. The appreciable individual variability of dynamics of formation of new motor coordination was revealed.

December 2024
Department of Occupational Therapy, Grand Valley State University, Grand Rapids, USA.
Parsonage-Turner syndrome (PTS) is a rare brachial plexus neuropathy with a sudden onset of upper extremity pain, weakness, and loss of range of motion (ROM). Studies on occupational therapy (OT) interventions are limited. The aim of this case report was to explore the OT experiences, interventions, and outcomes of a patient with PTS.

Humans adjust their movement to changing environments effortlessly via multisensory integration of the effector's state, motor commands, and sensory feedback. It is postulated that frontoparietal (FP) networks are involved in the control of prehension, with dorsomedial (DM) and dorsolateral (DL) regions processing the reach and the grasp, respectively. This study tested (5F, 5M participants) the differential involvement of FP nodes (ventral premotor cortex - PMv, dorsal premotor cortex - PMd, anterior intraparietal sulcus - aIPS, and anterior superior parietal-occipital cortex - aSPOC) in online adjustments of reach-to-grasp coordination to mechanical perturbations that disrupted arm transport.

Background And Aims: Maternal diet and health may influence a child's later neurodevelopment. We investigated the effect of maternal diet, adiposity, gestational diabetes mellitus (GDM), and depressive/anxiety symptoms during pregnancy on the child's motor outcome at 5-6 years.
Methods: The motor performance of 159 children of women with overweight or obesity (pre-pregnancy body mass index 25-29.
Comparison of stop-jump muscle synergies in amateur basketball players with and without asymptomatic patellar tendon abnormalities during simulated games.
Acta Bioeng Biomech

Faculty of Sports Science, Ningbo University, Ningbo, China.
: Asymptomatic patellar tendon abnormality (APTA) is considered a precursor to patellar tendinopathy (PT), but its pathogenesis remains unclear, especially regarding changes in muscle coordination. Therefore, it is essential to explore the muscle synergy patterns in individuals with APTA. This study recorded sEMG data during stop-jump tasks in 8 APTA and 8 healthy amateur male basketball players in a simulated basketball game.
