Figure 2From: EMGD-FE: an open source graphical user interface for estimating isometric muscle forces in the lower limb using an EMG-driven model Activation dynamics. Its implementation comprises two steps. The first is the second row of eq. (1), and the second is a non-linear algebraic equation, which augments low-level activations and is modulated by a single “A” parameter [19].Back to article page
