Drawing on fairness heuristic theory and the mutual verification of 269 two-wave time-lagged surveys and 303 cross-sectional surveys from gig workers working on different digital platforms in China, we demonstrate that interactional justice fully mediates the positive effect of platform work flexibility and the negative effect of platform work insecurity on affective commitment to the platform.

The findings reveal that both the spring cross-frame and movable hip belt designs preserve neutral pelvic mobility relative to normal gait. However, only the cross-frame design exhibited a coordination pattern between the pelvis and trunk similar to natural walking, possibly due to its ability to control trunk rotational range of motion (ROM).
