Abstract
STUDY OBJECTIVES: To test the effectiveness of strapping techniques in reducing lateral motion of volunteers restrained on a backboard. DESIGN: Randomized block experimentation. SETTING: Medical products research and design laboratory. PARTICIPANTS: Healthy adult volunteers with no history of head, neck, or back trauma. INTERVENTIONS: Subjects were restrained on a wooden backboard using a control and three variations of strapping techniques. The backboard was rolled 90 degrees to the side, and lateral motion of the torso was measured. MEASUREMENTS AND MAIN RESULTS:Nineteen subjects participated. Technique 2, which added an abdominal strap to the control technique, reduced 26% of the lateral motion. CONCLUSION: Additional, specifically placed strapping should be added to the torso to reduce lateral motion on a backboard. Further study is needed to determine the effect of lateral motion in the spine and potential benefits of reduced motion.
