我们对年龄相关的上肢本体感受能力下降的理解是有限的。此外，体力活动可能在多大程度上改善与年龄相关的本体感觉变化尚不清楚。上肢本体感觉敏锐度进行了检查，在年轻和老年人（活跃和久坐）右利手的成年人使用手腕位置匹配的任务，不同的处理要求。老年人还根据他们参与上肢特定任务的情况进行分类。年龄较大的人比年轻人的错误更大。久坐不动的老年人表现出更大的错误，并进行运动不如活跃的老年人顺利。非特异性组比上肢特异性组表现出更大的错误和更长的运动时间。在老年人中，感知肢体位置的能力下降可能与久坐不动的生活方式有关，并且与记忆和本体感受信息的传递有关。执行特定于上肢的任务可能会减少与年龄相关的本体感觉下降。
Our understanding of age-related declines in upper limb proprioceptive abilities is limited. Furthermore, the extent to which physical activity might ameliorate age-related changes in proprioception is not known. Upper limb proprioceptive acuity was examined in young and older (active and sedentary) right-handed adults using a wrist-position-matching task that varied in terms of processing demands. Older individuals were also classified according to their participation in tasks specific to the upper limb. Errors were greater for older than younger individuals. Older sedentary adults showed greater errors and performed movements less smoothly than older active adults. The nonspecific group showed greater errors and longer movement times than the upper-limb-specific group. In older adults, decreased ability to perceive limb position may be related to a sedentary lifestyle and declines associated with memory and transfer of proprioceptive information. Performing tasks specific to the upper limbs may reduce age-related declines in proprioception.
