Abstract
Objective:
To assess the effect of performing vestibular rehabilitation using the Cawthorne & Cooksey exercises supplemented by training of the breathing rhythm or proprioception exercises on self-reported disability and postural control, in patients with chronic, peripheral, vestibular disease.
Methods:
Fifty one patients with peripheral vestibular disease and abnormal caloric test participated in the study (mean age 43 ± S.D. 9 years). They were assigned to one of 3 treatment groups: I. Cawthorne &} Cooksey exercises with training of the breathing rhythm (n = 17); II. Cawthorne & Cooksey exercises with proprioception exercises (n = 17) and III. Cawthorne & Cooksey exercises with no additional intervention (n = 17). The Dizziness Handicap Inventory and static posturography were evaluated prior to treatment and at week 8 of follow-up.
Results:
Prior to treatment, composite scores on the Dizziness Handicap Inventory and static posturography were similar in the 3 groups. After treatment, a decrease of the composite score of at least 18 points was observed more frequently in patients of the respiration group (94%), compared to the proprioception group (53%) and the Cawthorne & Cooksey group (70%) (p = 0.03); while the proprioception group showed a significant decrease of oscillation during all sensory conditions of static posturography (p < 0.05).
Conclusion:
The results suggest that regulation of the breathing pattern may have an influence on disability related to chronic vestibular disease, while proprioception exercises may improve postural control. However, further studies are needed to evaluate if training of the breathing rhythm could be an additional tool for vestibular rehabilitation.
