Co-Contraction Embodies Uncertainty: An Optimal Feedforward Strategy for Robust Motor Control

2024-06-17

Abstract excerpt

Despite our environment is often uncertain, we generally manage to generate stable motor behaviors. While reactive control plays a major role in this achievement, proactive control is critical to cope with the substantial noise and delays that affect neuromusculoskeletal systems. In particular, muscle co-contraction is exploited to robustify feedforward motor commands against internal sensorimotor noise as was rev...
