In the same study, increased GMax activation in both SIJD patients and

PFJCA was based on knee-flexion angle: PF   contact area ( x ) = 0.0781 x 2 + 0.6763 x + 151.75 . (3) To determine PFJS, the PFJRF was divided by PFJCA for each data point during the stance phase of the hop. The following discrete variables were determined for each hop cadence: peak PFJS, PFJRF, PFJRF

-static balance control) by maintaining our center of mass (COM) within our base of support. Common metrics of quasi-static balance control (ie, postural steadiness) can be derived from underfoot center of pressure (COP) measures during quiet standing, 8 and different stance configurations (ie, double leg

collected in both an open-heeled, double-legged stance and a single-leg stance on the participant’s dominant leg. Dynamic balance measures were collected using the commercially-available Y Balance Test (YBT) (Functional Movement Systems Inc., Chatham, VA). The YBT is a portable assessment of dynamic balance

Each subject performed 3 trials, with a trial considered “good” if the subject’s approach speed fell within the 4.5 to 5.5 m/s limit and the foot landed within the stance/pivot area necessary to successfully

strategy based on vertical ground reaction impulse (vGRI). This variable represents the cumulative load applied vertically to the lower limb throughout stance, but does not require real-time inverse dynamics calculations, establishing a low barrier to adoption. We theorize that vGRI could be an effective
