Comparison of the Plantar Pressure Distributions at Different Cane Lengths

Abstract

Abstract.[Purpose] The purpose of this study was to compare plantar pressure distributions of the affected side of stroke patients during walking with canes of three different cane lengths.[Subjects] Thirty-four stroke patients participated in this study. [Method] The three different lengths of cane were: to the top of the greater trochanter, 5 cm above the greater trochanter, and 10 cm above the greater trochanter. The measured parameters were foot contact area, length, width, pressure, and the center of pressure trajectory during the stance phase, from heel-strike to toe-off.[Results] Our data revealed significant increments in the contact width and pressure of the hind foot at the cane length of 10 cm above the greater trochanter. Anterior/posterior center of pressure trajectory also significantly increased at cane lengths of 5 and 10 cm of above the greater trochanter.[Conclusion] The plantar pressure distribution for cane lengths above the greater trochanter were clinically beneficial and more effective at increasing weight shifting to the affected hind foot and harmonizing paralyzed heel strike with better displacement of pressure.
