Proprioceptive Acuity Assessment in Multiple Directions Across Multiple Joints in the Upper Limb
This study aimed to investigate the effect of direction and joint angle on upper limb proprioception. Thirty individuals (all males) completed a position reproduction activity in 13 directions and three joint angles. It was discovered that upper limb proprioception is dependent on joint angle, direction, and range of motion. The position reproduction error was found to be dependent on the direction, which had a significantly lower accuracy in the direction with a larger range of motion. In addition, upper limb repositioning errors increased at greater limb elevation angles. Our findings also showed that the joint angle did...

Immediate Effects of Real-Time Feedback During Overground Gait Performed Using Inertial Measurement Units on Gait Parameters in Healthy Young Participants: A Cross-Sectional Study
This study might imply the possibility of clinical application for overground gait training, and further studies are needed to clarify the effectiveness for older people.PMID:37487588 | DOI:10.1123/mc.2022-0122 (Source: Motor Control)

Judokas Exhibit Short Response Latency Even to Non-Judo-Specific External Perturbation: Insights Into the Involuntary Postural Control Ability in Humans
Motor Control. 2023 Jul 19:1-12. doi: 10.1123/mc.2023-0026. Online ahead of print.ABSTRACTHumans experience unanticipated external postural perturbations and recover their posture faster via involuntary responses than voluntary responses. Previous cross-sectional comparisons between athletes and untrained populations have suggested that daily motor experiences can lead to adaptations in the reflex system, but the temporal aspect of this adaptation has been unclear. Here we show that judokas have an earlier muscle activation response to even non-judo-specific external perturbations compared with an untrained population. The...
