title: Physical therapy outcomes for persons with bilateral vestibular loss.
abstract: OBJECTIVE
  The purpose of the study was to assess the efficacy of physical therapy for patients with bilateral vestibular loss.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  Twenty-four patients with a diagnosis of bilateral vestibular loss were identified by a retrospective chart review. Thirteen of the 24 patients met the inclusion criteria of having a moderate or greater loss of vestibular function bilaterally as rated by an otoneurologist based on the patient's vestibular function tests. These patients were treated with a custom-designed physical therapy program for a mean of 4.6 visits over an average period of 3.8 months. Patients completed the Dizziness Handicap Inventory and the Activities-specific Balance Confidence Scale at initial evaluation and discharge. Patients were asked to perform the balance and gait tasks of the Dynamic Gait Index, Sensory Organization Test of computerized dynamic posturography, and the Timed "Up and Go" test at their first and last physical therapy sessions. The number of falls in the previous 4 weeks and the use of an assistive device at initial evaluation and discharge were reported. Composite score, an overall score of clinical outcome, was calculated to determine clinically significant changes in physical performance and subjective information.
  
  
  RESULTS
  On a population basis, statistically significant improvement was observed after physical therapy for each of the outcome measures including the composite score (P < .05). Clinically significant changes were demonstrated by 33% to 55% of the patients on the various outcome measures. No change was noted in the patients' risk of falling, their number of falls, and the use of assistive devices.
  
  
  CONCLUSIONS
  Many patients with bilateral vestibular loss benefit from an individualized vestibular physical therapy exercise program based on improved physical function and reduced self-perceived levels of handicap.
