Assessing for a Neuromotor Signature of Malingering in mTBI using BKG

Abstract

The present study will involve the administration of SportGait, a mobile screener of concussion, and the TOMM2 to two groups of participants. The instructed malingering (IM) group will complete the study as if they have a concussion after receiving information regarding head injuries, while the naive malingering (NM) group will complete it as if they have a concussion without additional information. The neuromotor measure included in this study is the SportGait Biokinetograph (BKG), which uses data obtained by sensors in the mobile phone to create a profile of an individual's gait cycle, including variables related to speed, power, stability, and symmetry. The neurocognitive, neuromotor, and TOMM 2 data, along with concussion symptom endorsements, of these two groups will be compared with previously collected SportGait data from individuals who had mild traumatic brain injuries (mTBI) and normal controls (NM) in order to see if there are unique neuromotor signatures of malingering of mTBI
