Validation of a multi-body optimization with a knee model including deformable ligaments

Abstract

test reliability of the signal in healthy adults. Also, EMGwaveforms fromMG and TA are similar to previous reports using both FW and surface sensors [2,3]. This similarity suggests that the fine wire sensors adequately represents the muscle activity even though a FW sensor measures action potentials from an effective number of motor units within a relatively small detection volume [3]. Murley et al. [2] shows a similar pattern of TP EMG profile. Therefore the EMG profile from FW sensors represents the activity of TP during gait. In conclusion, despite the small detecting volume, EMG signals detected by a FW sensor can be taken as representative of activity of the entire muscle in TP, MG, and TA. The result is also repeatable in healthy adults.
