Rg. Jacob et al., Vestibular rehabilitation for patients with agoraphobia and vestibular dysfunction - A pilot study, J ANXIETY D, 15(1-2), 2001, pp. 131-146
This study examined whether physical therapy with vestibular rehabilitation
exercises would benefit patients with agoraphobia and vestibular dysfuncti
on. Nine patients went through a 2-week no-treatment baseline phase, a 4-we
ek behavioral treatment phase focusing on self-directed exposure, and an 8-
12-week vestibular rehabilitation phase (weekly sessions). On the main outc
ome measure, clinical global impressions (CGI) ratings of severity, behavio
ral treatment was accompanied by a reduction in severity (effect size d=0.8
; P < .10). On the supplementary measures, the Hamilton Anxiety Scale (Hami
lton-A) and the Chambless Mobility Inventory (Mi), no significant improveme
nts were noted. After vestibular rehabilitation therapy, further improvemen
t occurred in CGI severity (d=0.65; two-tailed P < .10), and significant im
provements occurred in the supplementary measures. The physical therapist i
dentified motion-induced dizziness and disturbances in balance in most pati
ents. These improved with rehabilitation. Although the results can be attri
buted to other explanations, they are not inconsistent with the hypothesis
that vestibular dysfunction maintains agoraphobic symptoms in some patients
