Movement based interventions such as imagery and action observation are used increasingly to support physical rehabilitation of adults during early aging. The efficacy of these more covert approaches is based on an intuitively appealing assumption that movement execution, imagery and observation share neural substrate; alteration of one influences directly the function of the other two. Using eye movement metrics this paper reports findings that question the congruency of the three conditions. The data reveal that simulating movement through imagery and action observation may offer older adults movement practice conditions that are not constrained by the age-related decline observed in physical conditions. In addition, the findings provide support for action observation as a more effective technique for movement reproduction in comparison to imagery. This concern for imagery was also seen in the less congruent temporal relationship in movement time between imagery and movement execution suggesting imagery inaccuracy in early aging.
基于运动的干预措施，如意象训练和动作观察，越来越多地被用于支持成年人在衰老早期的身体康复。这些更为隐蔽的方法的有效性基于一个直观上有吸引力的假设，即运动执行、意象训练和观察共享神经基质；其中一个的改变会直接影响另外两个的功能。本文使用眼动指标报告了对这三种情况的一致性提出质疑的研究结果。数据显示，通过意象训练和动作观察来模拟运动，可能为老年人提供不受身体状况中与年龄相关的衰退所限制的运动练习条件。此外，研究结果支持动作观察是一种比意象训练更有效的运动再现技术。在意象训练和运动执行之间的运动时间上不太一致的时间关系中也可以看到对意象训练的这种担忧，这表明在衰老早期意象训练不准确。
