Variability in cross-modal proprioceptive judgements impairs upper-limb function across the lifespan

Résumé fourni par la source

This is the first study to estimate the effect of proprioception on upper-limb function across the lifespan within an explicitly defined causal framework. Specifically, we investigated whether deficits in low-level proprioceptive judgements (made within a single frame of reference) or high-level proprioceptive judgements (made between frames of reference) impair upper-limb function across the lifespan. We provide novel evidence that imprecise high-level proprioceptive judgements impair an everyday upper-limb functional task, with this relationship strengthening with age.
