Abstract

OBJECTIVE

The present study aimed to investigate the impact of emotion on force steadiness of isometric precision pinch grip that is not direction-specific.

METHODS

Thirty-two healthy volunteer subjects participated in the present study. Subjects were divided into two experimental groups: pleasant image group and neutral image group. The isometric precision pinch grip task was performed for three times. Specifically, the first task was performed before pleasant or neutral picture viewing, the second task was performed immediately after picture viewing, further the third task was performed 30 seconds after the second task. During the isometric precision pinch grip task, participants were asked to exert pinch grip force at 10% of maximal voluntary contraction with visual feedback. The coefficient of variation of force production and normalized root mean square value of electromyography activity were calculated.

RESULTS

After pleasant picture viewing, coefficient of variation of pinch force production and normalized root mean square value of electromyography was decreased. While, in the neutral image condition, theses variables were not altered. More important, compared to the neutral image condition, pleasant emotion led to lower coefficient of variation of pinch grip force production.

CONCLUSION

These findings indicate that pleasant emotion improves force control of isometric precision pinch grip. Therefore, in clinical settings, the emotional state of patients may affect the effectiveness of rehabilitation and should be taken into consideration.

摘要

目的

本研究旨在探讨情绪对非特定方向的等长精确捏力稳定性的影响。

方法

32名健康志愿者参与了本研究。受试者被分为两个实验组：愉快图像组和中性图像组。等长精确捏力任务进行了三次。具体而言，第一次任务在观看愉快或中性图片之前进行，第二次任务在图片观看后立即进行，第三次任务在第二次任务后30秒进行。在等长精确捏力任务期间，要求参与者在视觉反馈下以最大自主收缩的10%施加捏力。计算了力产生的变异系数和肌电图活动的归一化均方根值。

结果

观看愉快图片后，捏力产生的变异系数和肌电图的归一化均方根值降低。而在中性图像条件下，这些变量没有改变。更重要的是，与中性图像条件相比，愉快情绪导致捏力产生的变异系数更低。

结论

这些发现表明，愉快情绪可改善等长精确捏力的力控制。因此，在临床环境中，患者的情绪状态可能会影响康复效果，应予以考虑。
