Development of a THOR Anthropometric Test Device Lumbar Spine Injury Risk Function

Currently, the Brinkley Dynamic Response Criteria (BDRC) is used to assess the risk of thoraco-lumbar spinal injury for astronauts. The BDRC has been validated for predicting injury in military aircraft ejections (Brinkley, 1968; Brinkley and Schaffer, 1971). The objective of this study was to use the injurious data behind the BDRC and subinjurious human-volunteer data to develop an injury risk function for the Test device for Human Occupant Restraint (THOR) to predict probability of thoraco-lumbar spine injury during space vehicle landings.
