Fabrication and Application of a Standardized T1/T2 Mount

摘要

Human response to impact is studied at the Naval Biodynamics Laboratory (NAVBIODYNLAB) using a horizontal accelerator which propels a restrained subject in a sled along an indoor track. Similar research using a vertical accelerator will begin in the near future at the Laboratory. Experimental impact forces which affect the cervical spine and head are accurately reflected at the subject's first thoracic vertebra (T1), and consequently can be measured there. Adventitious movement of an acceleration measuring system at T1 can distort data and thereby diminish the validity of conclusions drawn from that data. A standardized T1/T2 mount has been fabricated and used to improve the study of human response to experimental impact. Gross slippage has not been evident since adopting the new mount and strapping techniques. (fr)
