Following on from our earlier findings of a close relationship between motor function and outcome after mild traumatic brain injury (mTBI), this study examined whether it might be possible to predict poor recovery in the form of postconcussion syndrome (PCS) based upon early eye and arm motor function. Within 1 week post-injury, we assessed 37 mTBI patients on measures of saccades, oculomotor smooth pursuit, upper-limb visuomotor function, neuropsychological status, and self-reported health condition. At 3 months, 8 patients met the criteria for PCS. Using discriminant function analyses, we examined whether this future PCS-group could be identified prospectively based on motor function, neuropsychological status, and self-reported health condition at 1 week post-injury. Early eye movement function was the most effective in distinguishing between PCS and non-PCS patients, achieving a sensitivity and specificity of 100% in the present sample. This was followed by self-reported early h...

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2014
Objective:To investigate whether repeat saccadic reaction time (SRT) measurements using a portable saccadometer is useful to monitor patients with mild traumatic brain injury (mTBI).Methods:Seven patients with newly-diagnosed mTBI and five agematched controls were prospectively recruited from an emergency Department. Saccadic eye movements, symptom self-reporting and neuropsychological tests were performed within one week of injury and again at follow-up three weeks post-injury. Control patients underwent saccade recordings at similar intervals.Results:Median saccade reaction times were significantly prolonged within one week post-injury in mTBI compared to controls. At follow-up assessment there was no significant between-groups difference. Changes in median SRT between the two assessments were not statistically significant. Four of the seven mTBI patients showed significantly increased SRT at follow-up; three of the mTBI patients and all controls showed no significant change. Amon...

To conduct a review of literature and quantify the effect that traumatic brain injury (TBI) has on oculomotor functions (OM). A systematic review and meta-analysis was conducted from papers that objectively measured saccades and smooth-pursuit eye movements in mild and severe TBI. The overall impact of TBI on OM functions was moderate and significant with an effect size of 0.42 from 181 OM case-control comparisons. The heterogeneity, determined using the random effect model, was found to be significant (Q (180) = 367, p < 0.0001, I = 51) owing to the variety of OM functions (reflexive saccades, antisaccades, memory-guided saccades, self-paced saccades and pursuits) measured and varying post-injury periods.The overall effect on OM functions were similar in mild and severe TBI despite differences in combined effect size of various OM functions. OM functions involving complex cognitive skills such as antisaccades (in mild and severe TBI) and memory-guided saccades (in mild TBI) were...

BackgroundDespite the prevalence of mild traumatic brain injury (mTBI, concussion) in a wide range of occupational, sport, and military settings, accurate diagnosis and optimal treatment of concussive injuries are delayed by several challenging obstacles. Ability to measure the multisensory functional integrity of numerous neuroanatomical pathways with multiple tasks (oculomotor, vestibular and reaction time) can capture impairments of brain function.Methods106 mTBI patients and 300 control subjects were tested in the vestibular labs at 2 military hospitals. Patients were tested 3 times at average 2.5, 8.5 and 15.8 days post-injury. All patients completed a health history questionnaire, a dizziness handicap index (DHI), a functional gait index (FGI), and Trail Making Tests (TMTs) and were assessed by a battery of tests with video-oculography (I-Portal VOG) comprised of a head mounted, high speed eye tracking system on a rotary chair device (I-Portal Neuro-Otologic Test Center).
