Abstract
Lower-limb exoskeletons are used in a wide range of scenarios. The extensive applications are based on the effective intervention on people, which relies on the understanding of the effect of the exoskeleton intervention on human body. Muscle synergy has been used previously as an important assessment metric to evaluate the intervention effectiveness of exoskeletons on the wearer. However, the exoskeleton has limitations in terms of the type of intervention applied. In this paper, we applied various resistance schemes to the standing phase of the gait cycle and analysed the effect of the hip exoskeleton on neuromuscular synergy and co-contraction. Experimental results indicated that the hip exoskeleton intervention altered muscle recruitment and coordination to some extent. The ankle joint antagonist muscles co-contraction was related to the resistance intervention in the support phase, and intervention results did not show a difference in the synergy complexity. Besides, the muscle synergy weight was discriminated under the interventions. It may help therapists to develop effective gait intervention strategies in the near future.
