Does proprioceptive acuity influence the extent of implicit sensorimotor adaptation in young and older adults?

Abstract

Is proprioceptive acuity linked to amount of implicit motor adaptation across ages? The latter is larger in old compared with younger people? In light of reliability-based sensory integration, we hypothesized that this larger implicit adaptation was linked to an age-related lower reliability of proprioception. Over 2 experiments and 130 participants, we failed to find any evidence for this. We discussed alternative explanations for the increase in implicit adaptation with age and the validity of our proprioceptive assessment.
