How Does Back Pain Affect Stability and Muscle Activities of the Trunk?
نویسندگان
چکیده
The purpose of this study was to examine the muscular activity and kinematics of the trunk during unstable sitting and to determine differences between healthy and low back pain (LBP) participants. The participant sat on a custommade chair that was allowed to swing freely in the sagittal plane. They were asked to regain balance after the chair was tilted forward 20o and released. The movements of the lumbar spine and pelvis as well as the chair motion were recorded using Fastrak Sensors. Electromyographic activities of the trunk muscles were recorded using EMG sensors. Trunk stability was evaluated using balancing error and the time required to regain balance. Data were compared between the two groups of participants in order to detect possible differences due to LBP.
