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

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 low back pain and asymptomatic subjects.

Material And Method: Twenty-three males and 17 females with chronic non-specific low back pain 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.
