Contribution of passive moments to inter-segmental moments during gait: A systematic review

Inter-segmental moments computed by inverse dynamic during gait come from active moments, due to muscle contraction, but also passive resulting the resistance of periarticular structures their deformation. The evaluation proportion inter-segmental that can be attributed has led divergent results. Thus, purpose this study was systematically search and synthesize evidence contribution healthy pathological gait. A broad systematic performed including four databases. Thirteen studies met all inclusion criteria. Results showed participate in a non-negligible way. For ankle, moment is 5-20% around push-off. knee, 40–98% late swing 10–80% single support phase. hip, it 20–50% at population, been shown may sometimes more important, either smaller or larger moment. These results suggest mechanisms contribute substantially normal human gait, facilitating propulsion braking joint. Passive structures, acting as elastic springs, thus help reduce energy cost studying better understand aetiology pathology.
