Fatigue, fatigability, motor control, and kinesthesia are independent phenomena

Fatigue should not be confused with fatigability. While fatigue refers to the subjective sensation of weariness, fatigability refers to objective decrements in performance (either physical or cognitive) over time (However, and as done in this study, fatigability can be a useful experimental manipulation to understand fatigue in health and disease (Last, we also observed that kinesthesia was not affected by the fatigue task nor decreased cerebellar excitability. These results suggest that optimal sensorimotor calibration and/or homeostatic regulation under fatiguing conditions may require a reliable estimation of our body in space. While we can afford to sacrifice motor control in a task that has no repercussions for our homeostatic state, we cannot afford to lose our understanding of where our body is in space. Doing so could potentially push us toward further dyshomeostasis and injury.
