This paper presents both normative thresholds of the distance of the Body Center of Mass (BCOM) to the Minimal Moment Axis (MMA) during able-bodied level walking that can be used as a proxy of whole-body angular momentum variations to characterize the instability of gait and a wearable framework to assess this indicator in the field. The results are based on experimental analysis of the gait of able-bodied subject from a motion capture system and on a preliminary comparison of wearable-based against optoelectronic- based assessment of gait instability in one asymptomatic subject and one person with transfemoral amputation.
