A Criterion Measure of Walking Capacity in Lumbar Spinal Stenosis and Its Comparison With a Treadmill Protocol

Abstract

The SPWT is presented as a feasible and reproducible criterion measure of walking capacity for use with LSS patients. Although a strong relationship was demonstrated between the treadmill protocol and the SPWT, a systematic bias was observed with patients walking significantly further in the SPWT (36% in mean).
