Title: Computerized Dynamic Posturography Testing in Concussion: A Systematic Review

Purpose/Hypothesis: Computerized dynamic posturography (CDP) has been utilized within research and clinical practice for assessment of sensory deficits following concussion. However, it is unclear if current evidence on psychometric properties supports its use. The purpose of this systematic review is to compile evidence on psychometric properties of CDP for individuals following concussion.

Number/Subjects: 7 research articles including 1239 participants that met inclusion criteria.

Materials/Methods: Relevant studies published between 1980 and September 2018 extracted from the following electronic databases: PubMed, CINAHL, SPORTDiscus, ScienceDirect, Cochrane Library, ProQuest Central, and PEDro. Additional resources identified by searching references of included articles.

Results: Eight articles met all selection criteria. Validity is assessed in two articles, sensitivity in five, specificity in four, likelihood ratio in one, MCID in one, and learning effect in one.

Conclusion: Although there is a high prevalence of concussions in military and athletic populations, there is currently no gold standard for concussion diagnosis, making return to sport and active duty decisions difficult for clinicians. When accessible, computerized dynamic posturography is useful for detecting sensory deficits secondary to concussion as evidenced by sensitivity and specificity measures. Further research is necessary to evaluate the psychometric properties in assessment of individuals who have sustained a concussion.
