Comparison of Optokinetic Stimulation Treatments

Summary

Persons with a vestibular (e.g. inner ear) disorder often report visual induced dizziness (ViD) symptom (i.e. postural and/or gait instability, dizziness, disorientation) provocation or exacerbation in environments with busy or conflicting visual motion including crowds and supermarkets. ViD is frequently associated with high disability levels, prolonged illness and poorer clinical outcome. Thus, effective treatment is a priority. Vestibular rehabilitation incorporating structured exposure to Optokinetic Stimulation (OKS) (e.g. a form of computer based intervention that involves the observation of moving visual targets to encourage visual scanning) significantly improves ViD symptoms with similar improvement noted for both 'low-tech' OKS provided via a DVD or a 'high-tech', expensive, full-field stimulus. No studies have investigated if 'lower-tech', cheaper Virtual Reality (VR) systems may be beneficial in treating ViD symptoms and whether these VR systems are more effective than an OKS DVD. The first aim of this work is to compare the effect of an OKS DVD vs "lower-tech" VR system on ViD symptoms in persons with a chronic peripheral vestibular disorder aged 18-50 years old. This study may help to identify more optimal treatment strategies in persons with a vestibular disorder.

Conditions

• Peripheral Vestibular Disorder

Interventions

DEVICE

Group B

The C2 CARE C2 Physio 2019.2 has been developed for physiotherapy rehabilitation purposes including vestibular disorders. Virtual reality environments will be provided via the VR Oculus Quest headset as part of the OKS exposure incorporated within a customised VRT programme. Participants will attend 45 minute individualised supervised sessions once weekly for 8 weeks. Participants in this rehabilitation group will also have a home-based exercise programme to practise on days not attending clinic. The home-based programme will incorporate customised VRT exercises with exposure to VR environments using the VR Oculus Quest headset.

OTHER

Group A

Optokinetic stimulation treatment delivered through visual motion DVDs. Individualised 45 minute supervised sessions will occur for this group also once weekly for 8 weeks together with a home-based customised VRT programme incorporation the DVD to practise on days not attending clinic. Participants will have to use the OKS DVD for their exercises at home daily for 8 weeks as part of the prescribed home exercise programme.
