Over the past decade increasing number of US companies have been encouraging the use of abdominal support as a part of their efforts to reduce the human and economic costs due to back injuries. Back belts are assumed to prevent injuries by restricting posture, increasing intra abdominal pressure, providing psychological effect and relaxing trunk muscle to provide circumferential support around the pelvis ring. This research deals in detail with the posture restriction caused by back belt. Two-dimensional kinematic data was collected from ten subjects using nine marker positions. Angular displacement of nine body angles was compared. The kinematic relationship, posture, and interjoint coordination were studied using knee, hip, trunk and thoracic-lumbar joint. Out of the nine body joint angles, five showed decreased flexion, three increased flexion and remaining one had no change. Kinematic relationship was not found to exist between hip, knee, trunk and thoracic-lumbar joint. The behavior of postural index values supported the failure of kinematic relationship hypothesis. The back belt was found to make coordination between hip, knee, trunk and thoracic-lumbar joint less perfectly simultaneous.
