The aim of this study is to test whether when using the Vestibular Rehabilitation App older patients perform rehabilitation in a similar manner as when directly instructed by a clinician. A secondary goal is to evaluate usability and enjoyment of the app.
The main aim of this study is to test the prototype Vestibular Rehabilitation App (that has been specifically developed for this study) in the lab setting to evaluate if patients perform exercises with the app in a similar manner as when performing exercises in the traditional manner without the app. Errors in exercise performance identified by the app will be compared to those identified by a physical therapist. A secondary aim is to get feedback on enjoyment and ease of use of the Vestibular Rehabilitation App.

Delivery of vestibular rehabilitation through an app on a tablet or other portable device. The app takes patients through their rehabilitation session that has been prescribed by a clinician. Exercises are presented in the forms of games that are controlled by head or torso motion via a motion sensor that is placed on that body part. Data on the motion of the patient are calculated from sensor data and sent over the cloud for the clinician to access remotely.

Perceived Usefulness
The ease of use of information technology questionnaire is used to rate usefulness and perceived ease of use of the Vestibular Rehabilitation app. These are rated on a scale of 1-7, with 1 being the most positive response, 4 being a neutral response and 7 being the most negative response.
Time frame: Immediately after the testing
User Interface Satisfaction Questionnaire Outcomes
The questionnaire for user interface satisfaction (QUIS) is used to rate the Vestibular Rehabilitation app on use of its software and screen. These are rated on a scale of 0-9, with 9 being the most positive response and 0 being the most negative response.
Time frame: Immediately after the testing
Use Intention, Motivation and Enjoyment
A questionnaire on use intention, motivation, and enjoyment is used to rate the Vestibular Rehabilitation app on the use intention, motivation and enjoyment of the app. These are rated on a scale of 1-7, with 1 being the most positive response, 4 being a neutral response and 7 being the most negative response.
Time frame: Immediately after the testing
Change in Head Angle With the App
The IMU sensor data collected during the exercise performance with and without the Vestibular Rehabilitation App (collected in the same lab visit on the same group of participants) were analyzed to calculate peak head angles. These were analyzed to identify differences for the conditions with and without the Vestibular Rehabilitation App.
Time frame: During the testing with the app and during the testing without the app (up to 90 minutes)
Change in Range of Motion With the App
The IMU sensor data collected during the exercise performance with and without the Vestibular Rehabilitation App (collected in the same lab visit on the same group of participants) were analyzed to calculate head range of motion values. These were analyzed to identify differences for the conditions with and without the Vestibular Rehabilitation App

Time frame: During the testing with the app and during the testing without the app (up to 90 minutes)
Change in Head Motion Frequency With the App
The IMU sensor data collected during the exercise performance with and without the Vestibular Rehabilitation App (collected in the same lab visit on the same group of participants) were analyzed to calculate frequency of head motion. These were analyzed to identify differences for the conditions (arms) with and without the Vestibular Rehabilitation App
Time frame: During the testing with the app and during the testing without the app (up to 90 minutes)
Change in Balance Outcome With the App - Weight Shift Exercise
The IMU sensor data collected during the exercise performance with and without the Vestibular Rehabilitation App (collected in the same lab visit on the same group of participants) were analyzed to calculate range of motion in different directions during the weight shift balance exercise (in degrees). These were analyzed to identify differences for the conditions with and without the Vestibular Rehabilitation App
Time frame: During the testing with the app and during the testing without the app (up to 90 minutes)
Change in Head Angle With Feedback
The IMU sensor data collected during the exercise performance with the Vestibular Rehabilitation App will be analyzed to calculate peak head angles. Averages will be calculated for time windows before and after feedback on exercise performance is given. This will be analyzed to identify differences before and after feedback has been given.
Time frame: During the testing with the app (up to 45 minutes)
Change in Range of Motion With Feedback
The IMU sensor data collected during the exercise performance with the Vestibular Rehabilitation App will be analyzed to calculate range of motion values. Averages will be calculated for time windows before and after feedback on exercise performance is given. This will be analyzed to identify differences before and after feedback has been given.
Time frame: During the intervention with the app (up to 45 minutes)
Change in Angular Velocity With Feedback
The IMU sensor data collected during the exercise performance with the Vestibular Rehabilitation App will be analyzed to calculate angular velocity values . Averages will be calculated for time windows before and after feedback on exercise performance is given. This will be analyzed to identify differences before and after feedback has been given.
Time frame: During the intervention with the app (up to 45 minutes)
Change in Balance Outcome With Feedback
The IMU sensor data collected during the exercise performance with the Vestibular Rehabilitation App will be analyzed to calculate balance measures (jerk). Averages will be calculated for time windows before and after feedback on exercise performance is given. This will be analyzed to identify differences before and after feedback has been given.
Time frame: During the intervention with the app (up to 45 minutes)
Error Identification Differences
The exercise errors that are identified by the Vestibular Rehabilitation App and those identified by the physical therapist will be compared.
Time frame: During the intervention with the app (up to 45 minutes)
Change in Balance Outcome With the App - Single Leg Balance
The IMU sensor data collected during the exercise performance with and without the Vestibular Rehabilitation App (collected in the same lab visit on the same group of participants) were analyzed to calculate balance measure fluency (a non-dimensional derivative of jerk). This was analyzed to identify differences for the conditions with and without the Vestibular Rehabilitation App
Time frame: During the testing with the app and during the testing without the app (up to 90 minutes)
Open Ended Feedback
Participants will be asked for open ended feedback after the testing with and without the Vestibular Rehabilitation App. Discussions will be guided with questions. The questions were as follows: 1) Describe your overall experience as you used the app today?; 2) Explain the positive features of the app as you did your exercises?; 3) Describe the negative features of the app as you did your exercises today?; 4) What changes would you like to see in the app to support you as you do your exercises?; 5) Do you see any barriers to using the app while doing your exercises at home?
