Command timing volatility dataset

This dataset contains the data from four experiments: an elbow reaching experiment, isometric force control with the left and right hands, circle tracing with EMG from nine muscles (one participant), and acceleration variability measured from the left and right hands. It also contains the simulated reaching movements to eight targets with different levels of timing noise on the muscles, showcasing how volatile timing of the muscles can explain some of the motor impairments observed in patients with Huntington's disease, Parkinson's disease, and cerebellar ataxics.
