Criterion validity of 3D trunk accelerations to assess external work and power in able-bodied gait

“…In the presence of gait abnormality, the interpretation of the right-phase and leftphase ratios of positive versus negative external work, representing the loss and gain of energy during both functional stance phases, could be helpful [31]. However, we did not detect significant correlations for these ratios on either side; we stipulate that in pathological gait patterns, these correlations would be higher.…”

“…To describe symmetry, we defined right and left functional stance phases of the gait cycle. Functional stance phases have been defined as intervals between maximal AP velocities during the gait cycle [20,31]. The phase difference between the trunk and the CoM AP velocity resulted in an inversion of the temporal relation of AP velocity maximum to the VT displacement minimum.…”

“…Henriksen et al showed that accelerometry was reliable for the determination of step length, stride length and cadence [10]. www [25][26][27][28][29][30][31][32] Comparisons have been made between the kinematics of the lower trunk and the body centre of mass (CoM) during walking. Saini et al compared the sacral marker method with other methods of estimation of the vertical displacement of the CoM and reported moderate to moderately high correlations [11].…”

A Retrospective Single-Center Study of 23 Patients to Compare Gait Before and After Total Hip Arthroplasty Using the S-ROM Modular Hip System

“…Seen from a physical point of view, work is the product of force and the distance covered [ 46 ]. Seichert et al showed that from measured ground reaction forces, active and passive proportions can be differentiated by calculating the power curve and thus functional deficits can be ascertained [ 47 ]. The measured forces developed in this study in the knee ankle and opposite hip joint stayed equal to the control group.…”
