Abstract

The purpose of this study was to determine differences of balance performance to upright standing, forward bending posture, and sudden load during forward bending posture in subjects with and without a history of low back pain. A study was conducted on 8 subjects with low back pain and 13 healthy subjects. Dynamic Balance System was used to measure the postural sway index, left-right sway index, and anterior-posterior sway index on balance performance. There were no differences between subject groups on balance performance during upright standing. Balance performance was increased in forward bending posture and decreased in sudden load during forward bending posture in subjects with low back pain. These results suggest that subjects with low back pain demonstrated increased activity and decreased reaction times of trunk muscles.
