Running title: Trident Foam Alters Pressure Distribution During Walking.
Lateral wedge insoles (LWI) standalone or with proprietary arch support designs (Trident Foam) have been investigated for their effects on modifying gait biomechanics for people with knee osteoarthritis. However, plantar pressure distribution between these insole types has not been investigated and could provide insight towards insole prescription with concomitant foot symptoms taken into consideration. Regionally, medial rearfoot and forefoot pressure were reduced by all wedged insoles, with the Trident Foam supported-wedge showing greater reductions than the standalone wedge. Comfort ratings were not significantly different between insole conditions.
