Brief summary
The aim of the present study is to evaluate the impact of vestibular rehabilitation on metabolic aspects when evaluated by means of bioelectrical impedenzometry analysis, smart watch device and actigraphy in a group of vestibular hypofunction patients previously studied by means of video head impulse test, posturography and clinical validated scales
Detailed description
Recent advances in the field of vestibular-related disorders demonstrated that such conditions may interfere on different pathways underpinning metabolic behaviour, daily life activities and also chronotype behaviour. However, no studies evaluated how vestibular rehabilitation procedures - well established in literature - may interfere on these vestibular-related disorders. On the other side, recent advances in portable bioelectrical impedenzometry devices, smart watches devised to evaluate energy expenditure during daily life activities and actigraphy devices demonstrated to be useful in continuously monitoring different aspects of metabolic, activity and sleep behaviour. Thus, the aim of the present study is to evaluate the impact of vestibular rehabilitation on metabolic aspects when evaluated by means bioelectrical impedenzometry analysis, smart watch device and actigraphy in a group of vestibular hypofunction patients previously studied by means of video head impulse test, posturography and clinically validated scales
Interventions
The home exercise schedule consists of a patient-tailored association of adaptation (without and with the target moving on pitch and yaw planes for 1 min each three times per day), substitution, habituation, and balance and gait exercises. All the unilateral vestibular hypofunction patients will be followed in the clinic twice a week for 4 weeks for 30-45 min and evaluated for adherence. Between supervised sessions, patients will perform a twice-daily home exercise plan for a total of 30-40 min/day

Eligibility
Inclusion criteria
* unilateral vestibular hypofunction achieved according to accepted criteria, by bithermal caloric irrigation, showing at least 25% reduced vestibular response on one side when calculated by means of Jongkees' formula, 3 months or later after symptom onset. In order to avoid confounding factors, and following previous experiences, only subjects presenting with a concurrent reduction in vestibulo-ocular reflex (VOR) gain when studied by means of video head impulse test will be included in this study.
Exclusion criteria
* History of falls, cardiovascular, metabolic, rheumatologic, orthopedic, or other neurological conditions, liver or renal abnormalities. * pregnancy or breastfeeding. * Neurological and neuro-psychiatric diseases * insulin-dependent diabetes, vitamin deficiencies, hypothyroidism, lung diseases, hepatitis, chronic kidney failure, and Cushing syndrome * medication possibly impacting on cochleo-vestibular function or with a history of drug or alcohol addiction * inability to understand and agree to the examination procedures.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fat Mass Percentage | one month | Fat mass percentage will be calculated by using single-frequency BIA with eight-point tactile electrodes (Omron HBF-500 BIA, Omron Medizintechnik, Mannheim, Germany), whose reliability with DXA and MRI measurements was previously demonstrated will be used. This device uses an AC of 500 µA with a single frequency of 50 kHz and eight electrodes in a tetrapolar arrangement, requiring the subject to stand on metal footpads in bare feet and grasp a pair of electrodes fxed on a handle, with arms extended in front of the chest. |
| Muscle Mass Percentage | one month | Muscle mass percentage will be calculated by using single-frequency BIA with eight-point tactile electrodes (Omron HBF-500 BIA, Omron Medizintechnik, Mannheim, Germany), whose reliability with DXA and MRI measurements was previously demonstrated will be used. This device uses an AC of 500 µA with a single frequency of 50 kHz and eight electrodes in a tetrapolar arrangement, requiring the subject to stand on metal footpads in bare feet and grasp a pair of electrodes fxed on a handle, with arms extended in front of the chest. |
| Visceral Fat Level | one month | Visceral fat level will be calculated by using single-frequency BIA with eight-point tactile electrodes (Omron HBF-500 BIA, Omron Medizintechnik, Mannheim, Germany), whose reliability with DXA and MRI measurements was previously demonstrated will be used. This device uses an AC of 500 µA with a single frequency of 50 kHz and eight electrodes in a tetrapolar arrangement, requiring the subject to stand on metal footpads in bare feet and grasp a pair of electrodes fxed on a handle, with arms extended in front of the chest. |
