Clinical Balance Testing to Screen for Patients With Vestibular Disorders: A Retrospective Case-control Study

Objective: Identify clinical screening tests to proficiently screen for patients with vestibular disorders. Study design: Retrospective case-control study. Setting: Tertiary referral center. Patients: 318 healthy individuals and 331 subjects with vestibular disorders. Interventions: All subjects performed Romberg and Jendrassic maneuver with eyes closed (ROMJec), standing on foam with eyes open (SOFeo) and eyes closed (SOFec), Tandem Romberg with eyes open (TReo) and eyes closed (TRec), single leg stance with eyes open (SLSeo) and eyes closed (SLSec), Tandem gait (TG) and Timed Up and Go (TUG). Main outcome measures: Significant differences in performance on the balance tests. Results: For the age-group <40 years, TUG >6 seconds (OR 102.4; p <0.0001) and SLSec <30 seconds (OR 48.0; p <0.0001) proved to be the most predictive combination of testing (AUC 0.9; LR+ 15.8; LR- 0.2), with a positive predictive value (PPV) of 88.4%. For the age-group 40-60, TUG >7 seconds (OR 4.0; p = 0.0107) and TRec <30 seconds (OR 63.1; p < 0.0001) was the most predictive combination of tests (AUC 0.9 LR+ 6.0; LR- 0.1), with a PPV of 93.8%. For the age-group >60 the combination of TUG >8 seconds (OR 17.4; p < 0.0001) and SOFec <30 seconds (OR 10.4; p < 0.0001) was the most predictive (AUC 0.9 LR+ 6.3; LR- 0.2), with a PPV of 84.8%. Conclusions: Combinations of clinical tests are proposed to promptly screen for vestibular disorders in specific age groups. To interpret the results for the individual patient, the physician must take the history and the general examination into consideration.
