We read with great interest an article titled “Handgrip strength correlates with walking in lumbar spinal stenosis” authored by Inoue et al. [1]. They examined the relationship between handgrip strength and leg extension power, walking speed, and intermittent claudication for lumbar spinal stenosis (LSS). They concluded that the more handgrip strength patients with LSS have, the more LEP, the faster walking speed, the greater area of psoas muscle, the fewer steps for a 10-m walk, and the longer intermittent claudication they have. We would like to congratulate the authors for their commendable work in conducting the study. However, we have a few concerns for which we seek clarification.
