Abstract

Postural adaptability is related to central sensory integration and reweighting efficiency. Incline-interventions lead to lean after-effect (LAE), but it is not fully known how sensory reweighting may affect the magnitude and duration of LAE. We tasked fifteen young and healthy subjects with performing incline-interventions under conditions designed to perturb proprioception during or after the incline-intervention. We found that support surface configuration affected responses to tendon vibration. Additionally, vibration during an incline-intervention did not inhibit LAE, but vibration during an after-effect significantly affected LAE. Results reinforce claims that postural adaptation is based on modifications of central mechanisms of perception, not peripheral shank proprioceptors and improve our understanding of the role of sensory reweighting and sensory integration into postural adaptability.

摘要

姿势适应性与中枢感觉统合和重新加权效率有关。倾斜干预会导致瘦后效应 (LAE)，但尚不完全了解感觉重新加权如何影响 LAE 的程度和持续时间。我们让 15 名年轻健康的受试者在旨在扰乱倾斜干预期间或之后的本体感觉的条件下进行倾斜干预。我们发现支撑表面配置影响对肌腱振动的反应。此外，倾斜干预期间的振动不会抑制 LAE，但后效期间的振动会显着影响 LAE。结果强化了姿势适应基于感知中心机制的修改的说法，
