• Description:
  Inverse dynamics is a powerful tool for analysis of human movement [1], but is subject to error from various sources; these include estimates of segmental properties [2], skin artifacts [3], inaccuracies in center of pressure (COP) locations [4], and inherent noise in instrumentation. Previous studies have focused on the effect of only one or two error sources [2, 3, 4]. The combined effect of all sources of error on the calculated joint torques has not been investigated. A comprehensive analysis can provide a thorough understanding of uncertainties in inverse dynamics solutions. It can also lead to more effective error controls and improved algorithms for error correction such as the variance-weighted least-squares method [5]. This study seeks to provide a comprehensive analysis of most sources of error in inverse dynamics and their effects on computed lower extremity joint torques during gait.
