Effect of Unilateral Knee Extension Restriction on the Lumbar Region during Gait

Figure 2

The ensemble average of all participants of the bilateral multifidus (a) and erector spinae (b) “Normal” denotes normal walking, and “15°” and “30°” indicate the right knee extension restriction condition. Time was normalized across the whole gait cycle of the right lower limb. The shaded regions indicate early stance of the bilateral lower limbs, and peaks of those were analysed statistically. and indicate a significant difference between the normal condition at and , respectively. † and ‡ show significant difference between 15° at and , respectively.
