چکیده:
The purpose of this study was to investigate the effect of sensory manipulation and speed on the performance of dynamic bimanual coordination. To this end, fifteen physical education students from Shahid Beheshti University, with an age range of 18 to 25 years, performed in-phase and out-of-phase coordination patterns from slow to fast speeds in five different sensory conditions. To investigate the two movement patterns, two repeated measures ANOVA tests (5 sensory conditions × 3 execution speeds) were used for each of the in-phase and out-of-phase patterns, and the main effects were then analyzed using the Bonferroni post-hoc test. The dependent variable was relative phase error. The results showed that increasing the speed of movements had an effect on the performance of the 0180 out-of-phase movement pattern (P=0.001), but did not have an effect on the 00 in-phase pattern (P=0.9). The results of sensory manipulation showed that manipulation of vision and proprioception had an effect on the accuracy and variability of performing the two relative phases of movement patterns (P=0.001), but auditory manipulation had no effect on the performance of these patterns (P=0.315). In addition, this study showed the highest average relative phase error and standard deviation of relative phase error in the proprioceptive manipulation condition (P=0.001). In explaining the present findings, it can be said that the linear bimanual coordination task in this study is a proprioceptively dependent task.

PhD Student, Motor Learning, Urmia University, Urmia, Iran Abstract The purpose of the present study was to investigate the effects of sensory manipulation and speed on the performance of dynamic bimanual coordination.
Therefore, the author intends to Serrien Stability Grillo Tendon vibration To investigate the effects of information from three sources of multiple senses, namely proprioception, vision, and hearing, on the performance of in-phase and out-of-phase coordination patterns in a linear bimanual coordination task with increasing speed.
In other words, based on the Bonferroni post-hoc test, the effect of proprioception manipulation compared to normal sensory conditions (control condition) on the performance of the in-phase pattern was significant (P = 0.
In the present study, the type of auditory feedback manipulation, namely blocking the sound of the slides of the bimanual coordination tool, had no effect on the performance of coordinated movement patterns, which was inconsistent with the research of Ghez 5 and colleagues (2000) who had 54-year-old subjects with sensory pathology who had lost their depth sensation, Roche Bogaerts Central vision Spatiotemporal dimension Ghez They performed tasks consistent with the sound generated by the computer (14) and were consistent with the research of Grillo and colleagues (2010) and Rocha and colleagues (2011), which showed that the lack of hearing did not create changes in the performance of the subjects (28, 16).
