Decrease in Postural Sway and Trunk Stiffness During Cognitive Dual-Task in Nonspecific Chronic Low Back Pain Patients, Performance Compared to Healthy Control Subjects

Abstract

In nonspecific CLBP patients, a cognitive dual-task reduces both postural sway and trunk stiffness due to the distracting effect of the dual-task. This effect is only visible when the balance task is difficult.
