Abstract

Objective
This study was designed to investigate the effect of lateral wedged insole on foot of osteoarthritis patients.
Method
11 osteoarthritis patients participated in this study. Plantar peak pressures in shoes were measured by pedar^Ⱂ during a comfortable gait in three conditions (no wedge, with 5 degree wedged insole and with 10 degree wedged insole). Plantar pressure was analyzed by pedar C-expert program at TO (whole foot), M1 (medial heel), M2 (lateral heel), M3 (medial midfoot), M4 (lateral midfoot), M5 (1st, 2nd metatarsal area), M6 (3rd, 4th, 5th metatarsal area), M7 (great toe), M8 (2nd, 3rd toe area), M9 (4th, 5th toe area) zones respectively.
Results
There were significant differences in peak plantar pressures of whole foot, heel zone, and lateral midfoot zone according to wedge type. But there was no significant difference in peak plantar pressures at medial midfoot zone and forefoot zone according to wedge type.
Conclusion
There were difference in peak plantar pressures of osteoarthritis patients according to wedge type. (J Korean Acad Rehab Med 2006; 30: 153-157).
