| description | <b>Objective:</b> To reduce hip joint muscles’ activation during walking with an active hip exoskeleton. <b>Background:</b> Few studies examine the optimal active assistance timing of the hip exoskeleton based on muscle activation characteristics. <b>Methods:</b> Sixteen gender-balanced healthy adults (mean age 28.8 years) performed four tasks (each over 20 min). Tasks were different in loading and assistance. Muscle activation was collected by surface electromyography. The collected oxygen consumption evaluated the performance of the proposed active assistance strategy. <b>Results:</b> Experimental results verified that lower muscle activation and metabolism could be achieved when the active assistance gait phase was 9–60% of the gait cycle than that of all-gait-cycle active assist. <b>Conclusions:</b> Regulating the exoskeleton’s active assistance timing according to muscles’ activation characteristics can improve functional assistance. |
