Outcome Measures

Primary Outcomes (3)

  • Change in duration of the vestibular physical therapy exercise session

    The participants will perform vestibular physical therapy exercises for 30 minutes unless their dizziness symptoms prevend them to finish. The change in vestibular physical therapy exercises they can perform will be recorded by the investigator. This value will be recorded immediately after they finish their physical therapy exercises.

    up to 30 minutes

  • Change in dizziness index

    The dizziness index will be evaluated with the Dizziness Symptom Scale (DSS) with a scale from 1 (no dizziness) to 10 (strong dizziness). The change of DSS will be evaluated between participants wearing: * the transcranial vibrating system (TCVS) * no TCVS * the TCVS sham

    Questionaire immediately after the end of physical therapy exercise

  • Change in balance

    Participant's balance will be evaluated with a force plate platform (Bertec Device). Participants will be placed on the plate 1. eyes open, 2. eyes closed, 3. eyes open while standing on a foam pad, 4. eyes closed while standing on a foam pad. Each of the 4 conditions will involve the participant standing barefoot on a force plate platform for 10 seconds. The change in participant's balance (X\&Y direction) will be assessed by recording values of the Bertec device in two conditions: first with participants not wearing the TCVS and second with participants wearing the TCVS at optimal vibration frequency or wearing the TCVS sham. Clinical parameters obtained from the Bertec system will be recorded, including "falls" and will be compared between conditions to evaluate participant's change in balance. Participants will always be held safe with a harness secured to a mount point in the ceiling.

    During first and last vestibular physical therapy visit; expected duration maximum 10 minutes

Study Arms (2)

Transcranial vibrating system effect

EXPERIMENTAL

Participants will be enrolled for a 4 week period and will have 2 vestibular physical therapy (PT) visits per week. During the first 2 weeks (4 visits), 20 participants will perform their PT exercises (30 minutes or less if the participant is too dizzy to finish) wearing the transcranial vibration system (TCVS) and the other 20 participants without. The following 2 consecutive weeks (4 visits), participants will perform their PT exercises wearing the TCVS if they weren't previously, or won't wear the device during their PT exercises if they were previously. Outcomes measured: * at every visit: dizziness at the end of PT exercise (with dizziness symptom scale DSS); duration of PT exercise * at the first and last visit: force plate system assessment (balance)

Device: Transcranial vibrating system

SHAM COMPARATOR

40 participants will be enrolled for a 4 week period and will have 2 vestibular physical therapy (PT) visits per week. Participants will perform their PT exercises (30 minutes or less if the participant is too dizzy to finish) wearing the transcranial vibration system (TCVS) at optimal vibrating frequency or wearing the TCVS at irrelevant vibrating frequency (sham). The TCVS and TCVS sham will be labeled A or B by the sponsor. The investigators and participants will not know which TCVS is optimal or sham. The sponsor will randomly assign participants TCVS A or B. Outcomes measured: * at every visit: dizziness at the end of PT exercise (with dizziness symptom scale DSS); duration of PT exercise * at the first and last visit: force plate system assessment (balance)

Device: Transcranial vibrating systemDevice: Transcranial vibrating system sham

Interventions

The transcranial vibrating system (TCVS) will be worn by participants performing vestibular physical therapy (PT) exercises. The TCVS vibrating element will be placed against the skull, preferably over the mastoid bone behind the ear and will be hold in place by a headband. The TCVS will be worn during the whole time of the vestibular PT exercise (30 minutes) or less if the participant is unable to complete its exercises. The TCVS will be set at an optimal vibration frequency as determined in a previous study.

Transcranial vibrating system effectVs transcranial vibrating system sham

A transcranial vibrating system (TCVS) sham set at an irrelevant vibrating frequency will be worn by participants performing vestibular physical therapy (PT) exercises in arm 2. The TCVS sham vibrating element will be placed against the skull, preferably over the mastoid bone behind the ear and will be hold in place by a headband. The TCVS sham will be worn during the whole time of the vestibular PT exercise (30 minutes) or less if the participant is unable to complete its exercises.

Masking Details
Arm 1: their will be no masking as the participants will either wear the transcranial vibrating system (TCVS) or not. Arm 2: the investigators will be provided 2 TCVS by the sponsor, labeled A or B, which will be randomly assigned to participants by the sponsor. One TCVS will be set at the optimal vibration frequency and the other TCVS will be set at an irrelevant vibration frequency (sham). The investigators and the participants will not know which TCVS is optimal or sham, thus the arm 2 will be double blinded.

Intervention Model
SEQUENTIAL
Model Details: Arm 1: Participants undergoing vestibular physical therapy (PT) will perform PT exercises with or without wearing the transcranial vibrating system (TCVS). Following the end of their PT exercises (30 minutes or less if the participant was too dizzy to finish), participants will evaluate dizziness using a dizziness symptom scale (DSS) and PT exercise duration will be recorded. A force plate system assessment will also be performed with or without wearing the TCVS during the first and last PT visit to evaluate participant's balance. Arm 2: Participants will undergo the identical protocol as arm 1 with the exception that participants will wear the TCVS at optimal vibration frequency or the TCVS at irrelevant vibration frequency (sham). To determine TCVD's effect on dizziness and balance, the outcomes measured in both arms (1. DSS, 2. duration of PT exercise, 3. balance) will be compared statistically between: * TCVD versus no device * TCVD optimal frequency versus TCVD sham
