Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The overall duration of the treatment intervention is 9 weeks. Participants undergo a full subjective assessment of their condition at baseline and then complete self administered questionnaires that rate their perception of the problem and how this impacts on daily function and quality of life in the week prior to arriving for baseline assessment in Week 0 below.

Week 0 (90 minutes) - Physiotherapist 1 will perform a baseline balance and gait assessment for each participant.

Based on the assessment findings, participants will be given a tailored home exercise program consisting of habituation, gaze stability, and balance exercises. Participants will be asked to complete these exercises taking 10-15 minutes, three times daily for the duration of the 9 week rehabilitation. All participants will be asked to fill in a home exercise diary in order to record completion of the exercise programme.

Weeks 1 and 5 (30 minute review session) - Physiotherapist 2 will review and modify exercises as necessary. Review sessions will take approximately half an hour. A compliance measure for adherence to exercise programmes will be taken at these times for both groups.

At weeks 1 and 5, those participants in the intervention group of standard plus otolith specific vestibular rehabilitation program will be given added exercises to those above involving linear movement of head and/or movement of head position to change orientation with respect to gravity (eg side tilt or bouncing while sitting on a compliant surface). These exercises may add a further 5 minutes to their exercise program.


Week 9 (60 minute review session) – Physiotherapist 1 will repeat the balance and gait assessment and questionnaires.

6 months following baseline assessment (60 minutes) - Physiotherapist 1 will review the exercises and repeat objective outcome measures and questionnaires.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients are referred to a tertiary referral centre - the Vestibular Investigation Unit within the Royal Victorian Eye and Ear Hospital. Enrolment of participants will be done by the chief investigator after completion of vestibular function testing. Random allocation of the subjects to the intervention groups will be performed by an independent investigator. Group allocations will be shuffled and then drawn from a hat held at head height, ensuring that neither subject nor investigator has the ability to identify group allocation prior to selection.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
simple randomisation by drawing a number from a hat
Masking / blinding
Blinded (masking used)

Summary
Brief summary
The main aim of the project is to compare the response to treatment of patients with vestibular dysfunction between those receiving a standard program of Vestibular Rehabilitation (VR) versus those receiving the standard VR plus additional exercises that specifically target the otolith structures of the inner ear.The research hypotheses are:
1. That additional otolith training exercises will improve the short term effectiveness of a customized program of vestibular rehabilitation, and
2. That the improved short term outcomes from vestibular rehabilitation with additional otolith training exercises will be maintained in the longer term.
