Lower Extremity EMG-Driven Model Calibration Software and Data

Andrew Meyer & BJ Fregly
A package containing 1) Matlab code for performing EMG-driven neuromusculoskeletal model calibration, 2) Scaled generic OpenSim full-body walking model with calibrated lower body joint locations and orientations for a single male subject with right hemiparesis. 3) Multiple cycles of experimental walking data (marker motion, ground reaction, and EMG data) collected on a tied-belt instrumented treadmill from the same subject walking at speeds ranging from 0.4 to 0.8 m/s.

Experimental Data and Simulations of Walking While Carrying Heavy Load

Christopher Dembia
Experimental data and muscle-actuated tracking simulations of male subjects walking while carrying heavy load. We collected motion capture data of 7 subjects walking in 4 different conditions: walking (a) without load at a freely selected speed, (b) without load at 80% of the freely selected speed, (c) while carrying 38 kg on the torso at a new freely selected speed, and (d) while carrying 38 kg at the same speed as in (a).

Simulations of Ideal Assistive Devices for Four Subjects

Christopher Dembia
OpenSim simulations of male subjects walking while carrying heavy load and wearing hypothetical ideal assistive devices. The simulations examined 7 massless devices that each provided unrestricted torque at one degree of freedom and in one direction: hip abduction, hip flexion, hip extension, knee flexion, knee extension, ankle plantarflexion, and ankle dorsiflexion. The simulations were used to estimate the optimal device torques, and the devices' effect on metabolic cost and muscle activity.
