背景和目的：一些研究已经证明了心理意象在提高运动成绩方面的有效性。然而，没有研究研究这种技术对老年人静态平衡的有效性。本研究评估了心理意象技术的有效性，旨在通过减少老年人的姿势振荡和注意力需求来改善静态平衡。方法：20名年龄在65 ~ 90岁的受试者，分为两组（对照组8名，实验组12名）参与研究。实验参与者每天接受为期六周的心理意象训练。测量前后振荡和横向振荡，双任务范式使用过程中的反应时，并在前测和后测期间回答贝格平衡量表，活动特定平衡信心量表和VMIQ问卷。结果如下：与对照组相比，心理意象训练组的注意力需求和姿势振荡（前后）显著降低。心理意象组的受试者在产生清晰生动的心理意象的能力方面明显更好，如VMIQ问卷所示，而活动特定平衡信心量表或贝格量表则无显著差异。结论：本研究结果支持心理表象的心理神经肌肉和运动编码理论。
Background and aims: Several studies have demonstrated the effectiveness of mental imagery in improving motor performance. However, no research has studied the effectiveness of such a technique on static balance in the elderly. This study evaluated the efficiency of a mental imagery technique, aimed at improving static balance by reducing postural oscillations and attentional demands in the elderly. Methods: Twenty subjects aged 65 to 90 years old, divided into two groups (8 in Control group and 12 in Experimental group) participated in the study. The experimental participants underwent daily mental imagery training for a period of six weeks. Antero-posterior and lateral oscillations, reaction times during the use of the double-task paradigm were measured, and the Berg Balance Scale, Activities-specific Balance Confidence Scale, and VMIQ questionnaire were answered during both pre-test and post-test. Results: Attentional demands and postural oscillations (antero-posterior) decreased significantly in the group with mental imagery training compared with those of the Control group. Subjects in the mental imagery group became significantly better in their aptitudes to generate clear vivid mental images, as indicated by the VMIQ questionnaire, whereas no significant difference was observed for the Activities-specific Balance Confidence Scale or Berg Scale. Conclusion: The results support psychoneuromuscular and motor coding theories associated with mental imagery.
