People with chronic low back pain have poorer balance than controls in challenging tasks

Purpose: To compare the balance of individuals with and without chronic low back pain during five tasks. Method: The participants were 20 volunteers, 10 with and 10 without nonspecific chronic low back pain, mean age 34 years, 50% females. The participants completed the following balance tasks on a...

Description
Summary:Purpose: To compare the balance of individuals with and without chronic low back pain during five tasks. Method: The participants were 20 volunteers, 10 with and 10 without nonspecific chronic low back pain, mean age 34 years, 50% females. The participants completed the following balance tasks on a force platform in random order: (1) two-legged stance with eyes open, (2) two-legged stance with eyes closed, (3) semi-tandem with eyes open, (4) semi-tandem with eyes closed and (5) one-legged stance with eyes open. The participants completed three 60-s trials of tasks 1-4, and three 30-s trials of task 5 with 30-s rests between trials. The center of pressure area, velocity and frequency in the antero-posterior and medio-lateral directions were computed during each task, and compared between groups and tasks. Results: Participants with chronic low back pain presented significantly larger center of pressure area and higher velocity than the healthy controls (p
