Fig. 4From: Physical human-robot interaction of an active pelvis orthosis: toward ergonomic assessment of wearable robotsHip, knee and ankle flexion-extension angle range of motion (ROM) for all speeds (slow (V1), self-selected (V2), fast (V3)) and walking conditions (natural walking –no APO- (NW), transparent mode -APO shadows the wearer- (TM), low assistance (AM1), moderate assistance (AM2), high assistance (AM3)). Each colored column is the average ROM; black columns represent one SD band. Red lines show significant (two-way ANOVA (p < 0.05) with Fisher LSD post-hoc) differencesBack to article page
