Multiple linear regression analysis of data of patients with lumbar spinal stenosis (n = 222).
Fig 3.
Two strategies used by patients with lumbar spinal stenosis to alleviate symptoms.
(a) Trunk flexion posture with an increased step length and hip extension angle. (b) Trunk upright posture with a decreased step length and hip extension angle. (c) Ideal walking posture of healthy people. Red arrows indicate the ground reaction force vector, blue arrow is the hip flexion moment, and green arc is the psoas major.
