Induced acceleration analysis quantifies the contributions of individual forces and moments to the accelerations, reaction forces, and powers produced during a task (Zajac et al., 2002). The analysis has been advocated in the assessment of muscle and joint moment function during locomotion (Anderson et al., 2003; Neptune et al., 2004; Siegel et al., 2004; Zajac et al., 2003). However, results and interpretations drawn from the analysis have differed considerably between studies. In this abstract, the induced power contributions of individual joint moments are shown not to be physically well-defined for a theoretical locomotor task.
