Timing of Frontal Plane Trunk Lean, Not Magnitude, Mediates Frontal Plane Knee Joint Loading in Patients with Moderate Medial Knee Osteoarthritis

Table 2

Mean (SD) duration (s) and proportion (%) that participants of each group spent in stance versus swing and specifically during weight acceptance (WA) during each limb’s gait cycle (GC).

Inv: involved limb; Uninv: uninvolved limb. Significant differences between groups for relative proportion of gait cycle (% GC) spent in stance versus swing ( of group by phase; ). Significant group difference for WA as % GC ( effect; ).
