Effectiveness of combined Vestibular Rehabilitation & Cognitive Behavioral Therapy in the treatment of Chronic Dizziness: A Systematic Review Authors: Rhonda Cooper, Erica Haker, Bryan Cervantes, April Pemble, Shaila Jiwa Supervisor: Dr. Janice Eng Outline „ Introduction „ Methods „ Results & Discussion „ Physiology „ Limitations & Future Research „ Summary INTRODUCTION Vestibular Rehabilitation   Cognitive Behavioral Therapy Canalith Repositioning Maneuvers Chronic Dizziness z 1/3 of older adults report experiencing dizziness and/or loss of equilibrium z 1/5 working age adults experience dizziness z 1/10 working age adults report experiencing dizziness as a handicap z The prevalence of dizziness may be underestimated as many people living in community have handicapping chronic dizziness that is neither diagnosed or treated Chronic Dizziness z Dizziness contributes to increased incidence of falls due to increased fear of falling precipitating falls z Dizziness leads to decreased social involvement and subsequent increased anxiety and risk of depression z Dizziness contributes to musculo-skeletal problems such as neck stiffness and headache Anxiety & Dizziness z Anxiety and Dizziness are co-morbid conditions in a larger percentage of the population than would be expected from chance z Many patients with anxiety disorders present with abnormal vestibular function z Many patients with vestibular disorder suffer from anxiety Vestibular Rehabilitation & Cognitive Behavioral Therapy METHODS Literature Search: Electronic Databases „ CINHAL „ Cochrane Central Register of Controlled Trials „ Cochrane Database of Systematic Reviews „ EBM Reviews – ACP Journal Club „ EMBASE „ Google Scholar „ PEDro „ PsycInfo „ PubMed „ Web of Science „ PapersFirst „ Proquest Dissertations and Theses Literature Search: Key Words „ Vestibular rehabilitation Exercise Exercise therapy Kinesiotherapy „ Cognitive behavioral therapy Cognitive therapy Behavioral therapy Psychotherapy „ Dizziness Vestibular disease Vestibular disorder Balance disorder Vertigo Literature Search: Limits „ English „ Up to June 2006 „ No limits imposed on the type of study „ Review papers excluded Literature Search: PubMed „ Large number of search results (783) „ Clinical queries filter • Limits results to randomized controlled trials (RCTs) „ Relevant articles link • Does not limit studies based on study design Literature Search: Other Strategies „ Web of Science • Author search feature: „ Yardley „ Andersson „ Johansson „ Holmberg „ Reference lists search Literature Search: Hand Searching „ All relevant journals were searched thoroughly using electronic databases „ Not implemented Inclusion Criteria „ Population: • Adults over 19 years of age with chronic dizziness „ Intervention: • VR combined with CBT „ Outcome: • Relevant measures for dizziness, anxiety and depression were considered • i.e. Dizziness handicap inventory (DHI) and vertigo symptom scale (VSS) Quality Assessment „ Modified version of Downs & Black Checklist for Measuring Study Quality • Applicable to both randomized and non- randomized studies „ 2 independent reviewers „ Disagreement resolution: • Consensus achieved by discussion among the 2 reviewers • 3rd reviewer available for mediation Data Extraction „ Modified version of the Cochrane Back Review Group data extraction form „ 2 independent reviewers „ Disagreement resolution: • Consensus achieved by discussion among the 2 reviewers • 3rd reviewer available for mediation RESULTS & DISCUSSION Study Selection „ Electronic data bases & examination of reference lists produced 320 studies „ 6 were selected for abstract or text screening „ 5 remaining underwent quality assessment & data extraction „ 4 were selected for this systematic review A controlled trial of CBT combined with VR in the treatment of dizziness Andersson et al. 2006 „ n = 29 „ VR & CBT vs. Wait-list control „ Significant treatment effects were found on self-reported handicap, behavioural measures of exposure to dizziness-provoking movements, & daily registrations of dizziness & distress associated with unsteadiness. „ No significant change from pre- to post- treatment was found in regards to self- reported measures of general distress. Randomized controlled trial of VR combined with CBT for dizziness Johansson et al. 2001 „ n = 19 „ VR & CBT vs. Wait-list control „ Statistically significant  improvements in the treatment group on walking time, 2 dizziness provocative movements, & on the DHI. „ No significance found on the Romberg, several of the dizziness provocative movements, or on the questionnaires measuring anxiety & depression. Feasibility & effectiveness of providing VR for dizzy patients in the community Yardley et al. 1998 „ n = 16 „ Pre-VR & CBT vs. Post-VR & CBT „ Improvements were found in the ability to undertake physical activities such as walking & climbing stairs, & how much dizziness interferes with different activities. „ There is some evidence to show that there is a decrease in postural sway. Treatment of phobic postural vertigo: A controlled study of CBT & self- controlled desensitization Holmberg et al. 2006 „ n = 31 „ VR & CBT vs. VR alone „ Significant, but small, improvement in experienced vertigo severity & handicap in the self-treatment group. „ Significant additional effects of psychological treatment showed improvements in patients’ experienced handicap, anxiety, & depression. „ Results suggest that the treatment effects obtained were less strong overall. Findings „ Combination of VR & CBT was found to be an effective intervention for patients with chronic dizziness in the majority of the outcomes measured by the 4 studies. „ However, we were unable to conclude that combined VR & CBT is more effective than either VR & CBT alone. PHYSIOLOGY Physiological links between balance and anxiety „ Physiological connection between balance disorders and anxiety. „ 4 vestibular nuclei located in the brainstem Æ input from the vestibular portion of C.N. VIII „ Parabrachial nucleus located in the brainstem The parabrachial nucleus network Æ emotional, affective, and physiological manifestations of fear and anxiety Æ convergence of vestibular, somatic, and visceral information processing Physiological links between balance and anxiety „ There is a direct link between the vestibular system and neural networks involved in expressing anxiety and emotions. LIMITATIONS Limitations „ Limited number of studies „ Limited quality of research examining VR and CBT „ Factors that contributed to the low quality scores are: ¾ Lack of randomization ¾ Small sample size ¾ Lack of control group ¾ Lack of blinding Limitations „ Only one of the studies compared combined VR & CBT to VR alone „ Variability in the research: ¾ patient populations ¾ interventions ¾ outcome measures ƒ Variability in the studies made it difficult to consolidate results and draw valid conclusions FUTURE RESEARCH Future Research „ Research that compares combined VR & CBT to VR alone is needed ¾ to help determine if combined use of VR & CBT is more effective than either intervention alone Future Research „ Study design needs to be improved: ¾ larger sample sizes ¾ randomization ¾ control groups ¾ homogeneity of patient population ¾ standardized interventions ¾ consistent outcome measures Future Research „ Need to consider the cost- effectiveness of combining CBT with VR „ CBT is an individualized one on one treatment ¾ need to investigate if CBT administered in groups could be as effective in reducing symptoms and be more cost- effective than individual treatment SUMMARY Summary „ Although combined VR & CBT was found to be an effective intervention for patients with chronic dizziness, we cannot conclude that it is a more effective intervention than either VR or CBT alone. „ Shortage of research in the area of VR and CBT „ Lack of standardization for both therapeutic methods. Summary „ Face validity exists for the use of VR & CBT „ Stronger evidence needed before valid clinical recommendations can be made References „ Grimby A, Rosenhall U.
