The Effect of Sensory Feedback on the Transition of the Relative Phase in Bimanual Coordination Task in old Adults
Introduction: The purpose of present research was the study of the effect of sensory feedback on speed of the relative phase transition in anti-phase bimanual coordination pattern across old adults. Materials and Methods: Therefore 15 intact male old adults selected in available with age range 60-7...

Materials and Methods: Therefore 15 intact male old adults selected in available with age range 60-70 years that were all of them hand-right.

Results: The findings revealed that main effects of proprioception (P = 0.001), audition (P = 0.001) and two-way interaction (P = 0.022) were significant.

With regard to older adults revealed more impairments in audition and proprioception than vision condition and also more variability and the speed of the phase transition, we could conclude that these population relied on audition and proprioception to perform bimanual coordination patterns.http://jrrs.mui.ac.ir/index.php/jrrs/article/view/2146Bimanual coordinationIn-phaseAnti-phaseRelative phaseold adult |
