A novel stability-based EMG-assisted optimization method for the spine
In the absence of accurate non-invasive in vivo techniques, musculoskeletal models are widely employed to compute biomechanical loads on different body joints during static and dynamic activities [1,2]. Three approaches have been proposed to resolve joint kinetics redundancy. First, a pure optimization technique in which muscle forces are estimated by optimizing an assumed cost function such as the sum of squared or cubed muscle stresses [3]. Second, a pure electromyography (EMG)-assisted approach in which muscle forces are estimated from an assumed muscle EMG-force relationship during the task under consideration [4 –6].
