Plantar Pressure Distribution Pattern during Mid-Stance Phase of the Gait in Patients with Chronic Non-Specific Low Back XXXX .

OBJECTIVE: To examine the characteristics of the plantar pressure distribution patterns during mid-stance phase of the gait cycle in subjects with chronic non-specific @entity1643 and asymptomatic subjects. MATERIAL AND METHOD: Twenty-three males and 17 females with chronic non-specific @entity1643 and age- and gender-matched asymptomatic subjects walked barefoot along a gait mat at comfortable speedfor three trials. The left and right plantar pressure distributions were recorded during mid-stance phase and divided into 12 areas. Descriptive statistics including mean and standard deviation of demographic data and plantar pressure were calculated, and plantar pressure distribution patterns were described. RESULTS: Mean and standard deviation of @entity158 rating scale of chronic non-specific @entity1643 group were 4.04  1.58. The average mean peak pressure of both chronic non-specific @entity1643 and asymptomatic subjects located at the fifth area (lateral aspect offorefoot) in both feet. However the modes of the peak pressure of subjects with chronic non-specific @entity1643 were in the different areas in the left and right feet. The distribution patterns of the average mean peak pressure were not the same in chronic non-specific @entity1643 and asymptomatic subjects. This altered foot contact in the subjects with chronic non-specific @entity1643 may be used to avoid @entity158 or to compensate for limited mobility of the lower limbs at pre-swing phase. CONCLUSION: At mid-stance phase of walking, the pressures on the plantar surface were unequally distributed in subjects with chronic non-specific @entity1643 .
