Abstract

[Purpose] The objective of this research was to examine the impact of cognitive load on the flexion relaxation phenomenon (FRP) during trunk flexion and return from flexion task. [Subjects and Methods] Twenty-two healthy subjects (18 males, 4 females) participated in the study. Each participant was exposed to 3 experimental conditions: no cognitive task, easy cognitive task and difficult cognitive task. Surface electromyography was used to measure lumbar erector spinae muscles activity level. Flexion relaxation ratio (FRR) was compared in order to assess the differences between the three experimental conditions during flexion and extension (FLX FRR and EXT FRR). [Results] The FRR was decreased with increase in cognitive difficulty; the difficult cognitive task was associated with significant lower value of FLX FRR in both sides. However, these changes were not significant in easy cognitive task. In addition, the EXT FRR was decreased in cognitive task conditions, but these results were not statistically significant except for difficult cognitive task condition in comparison to no cognitive task condition in left side. [Conclusion] These findings suggest that cognitive loading can affect FRP in healthy subjects.

摘要

[目的]本研究的目的是探讨认知负荷对躯干前屈及前屈后恢复任务过程中屈曲放松现象（FRP）的影响。[对象与方法]22名健康受试者（18名男性，4名女性）参与了本研究。每位参与者都经历了3种实验条件：无认知任务、简单认知任务和困难认知任务。采用表面肌电图测量竖脊肌的肌肉活动水平。比较屈曲放松率（FRR），以评估三种实验条件在屈曲和伸展过程中的差异（FLX FRR和EXT FRR）。[结果]随着认知难度的增加，FRR降低；困难认知任务与两侧FLX FRR的显著较低值相关。然而，在简单认知任务中，这些变化并不显著。此外，在认知任务条件下，EXT FRR降低，但与无认知任务条件相比，除左侧困难认知任务条件外，这些结果均无统计学意义。[结论]这些发现表明，认知负荷会影响健康受试者的FRP。
