This project is part of a large CIHR project on studying the safety of Spinal Manipulation Treatment (SMT). Our contribution is to develop virtual reality devices to communicate SMT instructions to chiropractic clinician. Similar to a heads-up display that helps fighter pilots land in the right direction and location, the SMT “co-pilot” will superimpose directional arrows and other information overtop a view of the patient to optimize delivery of desirable SMT parameters. 3D motion tracking and forces sensors will be used to confirm the clinician expertise at delivering those treatments.
