Precision grip, as the name implies, is the precise and stable application of fingertip forces. This grip style is essential for our hand skills. Occasionally, however, our fingers become unstable and snap into a hyper-extended posture. Suppressing this instability is crucial for hand dexterity, but how our nervous system does so is unknown. In this talk, I will present our work with human subject experiments and finger models to understand how the nervous system stabilizes our fingers. I will conclude by extending our results to the stability of general active mechanical networks.
