Degenerative changes in the lumbar spin and early pes pressures

Abstract

This study was designed to assess the correlation between degenerate joint disease (DJD) of the lumbar spine and early peak vertical forces attenuated through the lateral calcaneus during the gait cycle. Data was collected from 18 subjects, ranging in age from 22 to 60 years, who had been radiographically diagnosed with DJD of the lumbar spine. Measurement of vertical force over time was obtained using the electrodynograph system with standardized procedure. Results demonstrate that in patients with lumbar DJD the L-sensor, positioned on the lateral condyle of the plantar surface of the calcaneus, shows peak pressures at an early percentage of stance. These results indicate improper attenuation of initial forces through the axial skeleton during the gait cycle, potentially producing chronic overloading responsible for DJD of the lumbar spine. These findings imply that clinicians should consider the effects of high impact forces on an inverted calcaneus when evaluating and treating chronic low-back-pain patients.<>
