Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1. An initial vestibular physiotherapy screen to identify patients with a vestibular dysfunction will be undertaken within a week of admission on all patients admitted to the sub-acute rehabilitation unit following an injurious fall.
a) This screen will include
i. An oculomotor assessment - clinical assessment of eye movement control in sitting
ii. Clinical assessment of the vestibular-ocular reflex in sitting - the ability to move the head while maintaining focus on a specific point (stable gaze)
iii. Clinical assessment of dynamic visual acuity in sitting - a comparison of the ability to read standard Snellen eye chart keeping the head still and then while moving the head from side to side
iv. Positional testing to screen for Benign Paroxysmal Positional Vertigo (BPPV) with the standard clinical assessments of the Hall-pike Dix or side-lying test (lying down from sitting) and the roll test in supine

b) the clinical assessment will take a maximum of 30 minutes
c) the assessment will be undertaken in the physiotherapy gym by an appropriately trained staff physiotherapist

2. An appropriately trained staff physiotherapist will provide individualised vestibular rehabilitation protocols to all patients with a vestibular dysfunction on screening. This will be undertaken during usual physiotherapy rehabilitation sessions in the gym.
i. if BPPV is identified, the appropriate repositioning manouvres will be undertaken second daily until resolution of symptoms, taking a maximum of 15 minutes per session. No other vestibular rehabilitation exercises will commence until the BPPV has been resolved.
ii. if a vestibular system deficit is identified, appropriate gaze stability and / or vestibular rehabilitation exercises will be undertaken, for a maximum of 30 minutes per day, every day during the rehabilitation admission
iii. if a vestibular deficit is not identified, the participant will be allocated to the control group and will undertake usual sub-acute physiotherapy rehabilitation as detailed below
iii. all exercise interventions will be initially undertaken one-on-one and face to face, during the physiotherapy rehabilitation session in the physiotherapy gym. If participants are safe and able to undertake specific gaze stability exercises independently, each will be provided with an exercise sheet to enable independent practice.
iv. participants will keep an individual exercise record to monitor adherence
v. frequency and duration of all interventions will be at the discretion of the treating physiotherapist

3. 72 hours before discharge, a final vestibular assessment will be undertaken for those participants who were identified as having a vestibular dysfunction on initial assessment to ensure BPPV has not recurred or developed.

4. Discharge written home exercise programs incorporating appropriate vestibular rehabilitation exercises if appropriate will be provided by the treating physiotherapist, and will include the same format exercise record that has been used during the inpatient admission.

Rehabilitation
Comparator / control treatment
The control group will be comprised of those participants who had no vestibular dysfunction identified on initial vestibular physiotherapy assessment.
These participants will undertake usual sub-acute physiotherapy rehabilitation as directed by their treating staff physiotherapist. This program will include a daily program functional strengthening, dynamic balance exercises and gait retraining. An attendance log will be maintained.
Discharge written home exercise programs will be provided by the treating physiotherapist, and will include the same format exercise record that has been used during the inpatient admission.

Efficacy
Statistical methods / analysis
On average 5 patients per week are admitted to Brighton Health Campus for rehabilitation following an injurious fall. If three are recruited per week, this gives an estimated recruitment of 120 participants over the 9 months of planned recruitment. Published data on the prevalence of vestibular dysfunction in a subacute rehabilitation cohort like this does not yet exist but my clinical experience suggests that at least half of participants will have a vestibular dysfunction identified on clinical assessment. analysis will be undertaken with the guidance and advice of the statistician in the School of Allied Health, Faculty of Health Sciences, Australian Catholic University,
i. Descriptive statistics will be used to present the demographics and falls rates of the total group and percentage of patients in each of the three clinical classifications (no vestibular dysfunction, BPPV, vestibular dysfunction)
ii. Means (SDs) will be used to present the discharge and follow-up clinical outcome measures and questionnaires. Repeated measures general linear models and post-hoc analysis will determine any differences in clinical performance and self-report measures for all three clinical groups at both time points.
iii. Spearman Rank Order correlations will be undertaken to explore the associations between FGA scores, clinical outcomes measures and the number and frequency of falls amongst the three groups
iv. The associations between falls rates, balance confidence and quality of life will be explored amongst the three groups. To determine the clinical importance of between group differences, the ‘no vestibular dysfunction’ group will be considered the usual care group and used as a benchmark for comparison with outcomes in both vestibular dysfunction and BPPV clinical groups

Summary
Brief summary
Dizziness when moving (vertigo) is a common symptom of dysfunction in the vestibular system of the inner ear. Problems with this inner ear system can result on poor balance and falls. Trained vestibular physiotherapists can identify and manage common causes of vertigo and balance dysfunction. However, people who have been admitted to hospital following an injurious fall may not be able to move quickly enough to provoke vertigo, and therefore may not be identified as needing physiotherapy vestibular assessment and management, The aim of this study is to determine whether the identification and management of vestibular dysfunction in patients admitted to sub-acute rehabilitation after a fall decreases the rate of falls in the first three months back home after discharge.
