A theoretical note on models of interlimb coordination.

This article clarifies some points about models of interlimb coordination. The authors discuss in detail the predictions and extensions of the H. Haken, J.A.S. Kelso, and H. Bunz (1985) model and compare these to a truncated version used by R.C. Schmidt and colleagues. It is demonstrated that procedures commonly used to fit experimental data to model parameters require the fulfillment of certain assumptions. Finally, the authors show how recent experimental findings can be modeled straightforwardly using a system of coupled nonlinear oscillators.
