Vibrotactile Feedback Belt in Patients With Unilateral Vestibular Hypofunction (UVH)

Not Applicable
Not yet recruiting
Conditions
Vestibular Disorder
Interventions
Device: BalanceBelt
Registration Number
NCT06300840
Lead Sponsor
Hanna van Eijsden
Brief Summary

The goal of this clinical trial is to study the impact of a continuous vibrotactile feedback belt on balance, (fear of) falling, fatigue and overall functioning in participants with chronic disabling unilateral vestibular hypofunction.

The main questions it aims to answer are: • does wearing a vibrotactile feedback belt during waking hours for a week improve sense of balance and mobility, fear of falling, fatigue and overall functioning • does wearing a vibrotactile feedback belt influence static and dynamic balance and gait performance during balance and gait testing.

Participants will goes through different phases in an randomized order; a baseline phase, a sham phase (i.e., wearing the BalanceBelt while it is switched off) and an intervention phase (i.e., wearing the BalanceBelt while it is switched on).

It is expected that, just as with patients with bilateral loss of the balance organ, patients with a unilateral loss will also benefit from the BalanceBelt.

Primary Outcome Measures
NameTimeMethod
Mobility and Balance Score (MBS)Daily for 7 weeks

The MBS is a rating given by the patient on a scale ranging from 0 to 10, as a subjective grading of his or her overall mobility and balance in daily life. Where a higher score means a better score.

Secondary Outcome Measures
NameTimeMethod
physical activity_stepsDaily for 7 weeks

Number of steps a day

fallsDaily for 7 weeks

number of actual falls and near falls

Dynamic Gait Index (DGI)At the baseline and at the end of the study (8 weeks)

Dynamic Gait Index, score 0-24, higher score means better outcome

Timed up and Go test (TUG)At baseline and at the end of the study (8 weeks)

Timed up and Go test

Fear of fallingDaily for 7 weeks

Numeric rating scale, rang 0-10, where a higher score means a better outcome.

fatigueDaily for 7 weeks

Numeric rating scale, rang 0-10, where a higher score means a better outcome.

structured interview on compliance on wearing the Balancebelt(R)Daily for 7 weeks

compliance on wearing the Balancebelt(R)

Questionnaire: Dizziness handicap inventory (DHI)At baseline and at the end of the study (8 weeks)

Dizziness handicap inventory, score range 0-100, higher score means worse outcome.

General functioningDaily for 7 weeks

Numeric rating scale (NRS), rang 0-10, where a higher score means a better outcome.

physical activity_NRSDaily for 7 weeks

Numeric rating scale, rang 0-10, where a higher score means a better outcome.

Questionnaire: vestibular activity avoiding instrument (VAAI)At baseline and at the end of the study (8 weeks)

vestibular activity avoiding instrument, score range 0-54, higher score means worse outcome.

modified Clinical Test of Sensory Interaction on Balance (mCTSIB)At baseline and at the end of the study (8 weeks)
