Profiles of the elderly during transition from level walking to stair ascent upon VSS application. A Hip joint angle; B Knee joint angle; C Ankle joint angle; D Hip joint moment; E Knee joint moment; F Ankle joint moment; G Hip joint power; H Knee joint power; I Ankle joint power; J Support moment; For the joint angle, (+) indicates joint flexion and (−) indicates joint extension; For the joint moment, (+) indicates joint flexor moment and (−) indicates joint extensor moment; For the support moment, (+) indicates sum of extensor moments of the lower-limb joints; Arrows represent change by the VSS; HFM: Hip flexor moment; HEM: Hip extensor moment; KFM: Knee flexor moment; KEM: Knee extensor moment; AEM: Ankle extensor moment; HPP: Hip positive power; KNP: Knee negative power; KPP: Knee positive power; ANP: Ankle negative power; APP: Ankle positive power; SM: Support moment
