Effect of lower-extremity muscle fatigue on postural control1 Phillip A Gribble, MA, ATC, Jay Hertel, PhD, ATC Archives of Physical Medicine and Rehabilitation Volume 85, Issue 4, Pages 589-592 (April 2004) DOI: 10.1016/j.apmr.2003.06.031
Fig 1 Frontal plane COPV (COPfrontal). A significant condition by joint interaction (F2,26=3.18, P=.05) demonstrated that fatigue to the hip and knee musculature led to greater impairments in ML postural sway.

Fig 2 Sagittal plane COPV (COPsagittal). A significant main effect for fatigue existed across all 3 joints. Archives of Physical Medicine and Rehabilitation 2004 85, 589-592DOI: (10.1016/j.apmr.2003.06.031)
