Instrumented Gait Analysis to identify Persistent Deficits i
The results of this JAMA- Otolaryngology-Head & Neck Surgery study suggest that adults with chronic vestibular loss have clinically and functionally meaningful gait deficits.

The objective was to investigate the use of an instrumented 2-minute walk test in adults with vestibular loss, to further characterize vestibulopathic gait, and to assess whether those with chronic vestibular loss have enduring gait deficits.

The study recruited adults 20 to 79 years of age who were healthy or had confirmed unilateral or bilateral vestibular hypofunction. Of the 43 adults who were screened from the convenience and referred samples, 2 declined, and 7 were excluded because of health conditions. Data from 17 healthy adults and 13 adults with vestibular loss were analyzed. The primary measures were spatiotemporal gait metrics (eg, stride length [SL] and peak whole-body turning velocity).

Very large between-group differences were found for SL (left), SL (right), and peak turn velocity.

- The area under the curve was 0.79 for SL (left), 0.81 for SL (right), and 0.86 for peak turn velocity.

In this cross-sectional study, instrumented gait analysis had good discriminative validity and revealed persistent deficits in gait stability in those with chronic vestibular loss.
