Rehabilitation Oculomotor Screening Evaluation in Persons with Traumatic Brain Injury.

Background

Many individuals with traumatic brain injuries (TBIs) exhibit oculomotor dysfunctions that impact their daily functioning. As current clinical screening tools are limited, we have created and pilot-tested the Rehabilitation Oculomotor Screening Evaluation (ROSE) previously in a small sample of people with acquired brain injuries and neurotypical participants. The current study aims to validate ROSE in persons with TBI, focusing on mild TBI (mTBI).

Methods

Participants with TBI (n = 25) completed different clinical scales, including ROSE, Sensory Organization Test (SOT) for standing balance, Reintegration to Normal Living Index (RNLI), Timed Up and Go (TUG) for mobility, and a visual analogue scale for the subjective perception of visual vertigo. Neurotypical individuals (n = 24) who were age- and sex-matched completed only ROSE.

Results

The group with mTBI (n = 18) had significantly higher ROSE scores compared to the neurotypical group, with a large effect size. Significant correlation was found between ROSE and RNLI scores, but not with other clinical outcomes.

Conclusions

Significant between-group difference in ROSE scores and their association with RNLI scores suggest that ROSE is a valid tool in detecting oculomotor dysfunction in TBI. Future studies should continue the validation of ROSE in other TBI and neurologic populations and in larger sample sizes.
