ObjectivesTo measure cervical spine movement during removal of a motorcycle helmet by health care professionals.Material And MethodsObservational study using biomechanical inertial sensors to detect movement in the spinal column during removal of helmets.ResultsThirty-four emergency medicine specialists and nurses participated. The mean (SD) rotation was 1.14° (0.82°) to the left and 3.30° (1.69°) to the right (P<.001). Mean flexion was 9.82° (7.46°) and mean extension was 6.23° (6.86°) (P<.001). Mean lateral displacement was 5.73° (2.97°) to the left and 5.62° (8.22°) to the right (P=.678). The removal maneuvers took a mean of 70 seconds (4 seconds).ConclusionHelmet removal was completed in an average of 70 seconds with flexion and rotation mainly toward the side where the professional supporting the head was positioned.
