Rehabilitation interventions for oculomotor deficits in adults with mild traumatic brain injury: a systematic review protocol

IntroductionMild traumatic brain injury (mTBI) is the most common form of TBI with many individuals suffering from symptoms suggestive of deficits in oculomotor function. Although the symptoms are often experienced transiently, almost 50% of individuals will experience persistent symptoms. Oculomotor deficits can last months after injury and decrease function and the ability to participate in work, school and sport. To date, rehabilitation interventions targeting oculomotor deficits in mTBI have been reported on in several studies with varying study designs; however, the effectiveness of these interventions on measures of oculomotor function has not been established. The purpose of this paper is to present a protocol for a systematic review that aims to examine the effectiveness of rehabilitation interventions for improving function in adults with oculomotor deficits after mTBI.Methods and analysisSystematic searches in Medline Ovid, EMBASE, PsycINFO, CINAHL and Scopus will be conducted to identify experimental studies published in English from each databases inception date to present, involving adult patients with mTBI and oculomotor deficits. Citations will be saved and managed in EndNote V.20. Two independent reviewers will identify eligible studies and perform data abstraction. Any discrepancies will be solved by discussion, and a third reviewer will be consulted if necessary. A meta-analysis will be conducted for outcomes reported in two or more studies. The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol guidelines will be followed for reporting.Ethics and disseminationThis study does not involve primary data collection; therefore, formal ethical approval by an institutional review board is not required. Final results will be disseminated through open-access peer-reviewed publications. Abstracts will be presented at suitable national and international conferences or workshops. Furthermore, important information will be shared with clinical authorities, clinicians and at affiliated research institution-based websites and relevant servers.PROSPERO registration numberCRD42022352276.
