1 Introduction
Information from the Nationwide Well being and Diet Examination Survey (2001–2004) estimate that 35.4% of adults in the USA have vestibular dysfunction, and the incidence will increase with age (1). Newer research have confirmed these findings, exhibiting that 34% of community-dwelling adults over 50 years of age who current with complaints of dizziness to major care have a vestibular trigger for his or her dizziness (2, 3). Uncompensated vestibular hypofunction is related to signs of dizziness, visible blurring with head motion, and postural instability, which considerably enhance the chance of falls (1, 4, 5). Vestibular rehabilitation is an exercise-based intervention to advertise adaptation, habituation, and/or compensation for these useful deficits and has been confirmed to be efficient in lowering dizziness, enhancing postural stability, enhancing confidence with mobility, and lowering fall danger (6–8). The Medical Observe Pointers (CPGs) for vestibular hypofunction present evidence-based steering for train prescription, together with the optimum frequency, length, and varieties of workout routines to cut back signs and enhance steadiness and mobility (9, 10). Primarily based on the CPG, vestibular specialists sometimes present dwelling train applications within the type of handouts or therapy logs and advocate that sufferers carry out these workout routines between 3 and 5 occasions a day constantly and precisely (11). Sadly, lower than 50% of sufferers with vestibular hypofunction report doing the workout routines at dwelling (12), and constant completion of dwelling workout routines continues to be a problem (11).
From the affected person’s perspective, adherence to home-based vestibular workout routines is troublesome as a result of the workout routines are boring, they could not perceive how you can carry out the workout routines, they’re afraid as a result of signs of dizziness enhance whereas doing the workout routines, and an absence of suggestions whereas exercising at dwelling makes it troublesome to find out if they’re performing the workout routines accurately (12–15). Because of these limitations, sufferers often cease doing their workout routines, which might result in poor outcomes. Expertise-based train interventions have proven promising leads to selling adherence and engagement amongst older adults and in neurological populations resembling stroke, a number of sclerosis, and Parkinson’s illness (16–21). Nevertheless, technology-based options to extend engagement with vestibular workout routines are restricted. Hovareshti et al. (22) have developed the VestAid™ for service members and athletes after concussion damage, whereas Meldrum et al. (23) have created the VertiGenius™, which permits the prescription of individualized vestibular workout routines however with out the game-based characteristic.
To deal with the gaps in current applied sciences obtainable for treating vestibular dysfunction, we’ve got developed a game-based app with vestibular workout routines designed particularly for adults 65 years of age and older with dizziness. This app consists of options resembling a storyline, interactive characters, backgrounds with numerous levels of visible stimulation, and sport scores offered through the workout routines. The app was designed to be simple for older adults to make use of on a cellular platform, resembling a pill. In a earlier examine, the prototype app was examined with wholesome older adults, and the suggestions obtained was used to make iterative modifications within the app (24). Errors that had been generally made throughout workout routines had been recognized, and machine studying algorithms had been developed to detect errors in real-time and supply visible and auditory suggestions throughout workout routines to enhance the accuracy of train efficiency.
The purpose of this examine was to check the revised app on adults over 65 years of age with unilateral or bilateral vestibular hypofunction in a one-time laboratory session. The first purpose was to check the accuracy of train efficiency between the app and no-app circumstances. The secondary purpose was to evaluate affected person perceptions and experiences with the app utilizing validated questionnaires and open-ended questions.
2 Supplies and strategies
This was a single-arm potential examine that was accredited by the Institutional Evaluate Board on the College of Kansas Medical Middle. The examine was registered with clinicaltrials.gov (identifier NCT05436067).
2.1 Members
Members accomplished a screening type to verify they met the examine inclusion and exclusion standards. On the whole, the members who had been recruited from the outpatient clinic accomplished the screening type in particular person, whereas these recognized by way of database searches accomplished the screening type over the telephone. The inclusion standards had been as follows: (1) between 60 and 75 years of age, (2) have dizziness or imbalance as a result of a recognized unilateral or bilateral vestibular hypofunction, which may very well be as a result of vestibular neuritis, labyrinthitis, or Meniere’s illness, (3) have the ability to give knowledgeable consent, (4) have the ability to learn and communicate English fluently, and (5) have the ability to get out of a chair independently.
The exclusion standards had been as follows: (1) pre-existing neurological illnesses resembling stroke, Parkinson’s illness, a number of sclerosis, or traumatic mind damage and (2) historical past of latest surgical procedure or decrease extremity musculoskeletal damage or ache that will impede performing the steadiness workout routines.
A number of sources had been used for recruitment functions, together with (1) a hospital-based vestibular outpatient clinic, (2) the Healthcare Enterprise Repository for Ontological Narration (HERON) database, which is a search discovery instrument to go looking de-identified knowledge from the KU Well being System medical information, (3) the Frontiers registry on the College of Kansas Well being System, which incorporates folks with a recognized vestibular dysfunction who’ve agreed to be contacted for analysis functions, (4) the otolaryngology-head and neck surgical procedure affected person database of individuals with a recognized vestibular dysfunction, and (5) group referral.
2.2 General process
Human topic testing was carried out in a laboratory setting on the College of Kansas Medical Middle in a one-time session. All members signed knowledgeable consent earlier than the examine started. Testing started with amassing demographic data, adopted by a programs evaluation. All members accomplished the Dizziness Handicap Stock (DHI), Actions Particular Steadiness Confidence Scale (ABC), and Visible Vertigo Analog Scale (VVAS) on the pill utilizing the VestRx™ (analysis model). The train program design was equivalent for all topics, starting with VOR X1 workout routines within the yaw and pitch airplane, adopted by the weight-shift workout routines (anteroposterior, mediolateral, and omnidirectional) and single-leg steadiness workout routines. All members accomplished the train program each with the “app” situation and with out the app (the “no app” situation). The order wherein every participant accomplished the circumstances (app or no-app) was randomly assigned.
2.2.1 Experimental setup
The app software program was put in on an Android pill, and the rehabilitation video games had been managed by a MetaMotionR (MBientlab, Inc.) inertial measurement unit (IMU), linked to the pill through Bluetooth. Through the VOR video games, the IMU was positioned on the brow utilizing hypoallergenic adhesive tape, and IMU knowledge on head movement obtained within the app had been used to manage the character within the rehabilitation video games. Through the weight-shifting and single-leg steadiness workout routines, the IMU was secured to the waist utilizing a gait belt in order that pelvic movement managed the character within the video games. The pill was mounted on a stand at arm’s size from the participant and at eye stage for optimum use. Members carried out VOR workout routines whereas seated in a cushty chair, and weight-shift and single-leg steadiness workout routines whereas standing behind the chair. Through the app situation, the experimenter launched the app to the participant; nonetheless, instructions for workout routines had been primarily offered by way of the app. Earlier than the beginning of every train, members had been requested to carry nonetheless in order that the IMU was calibrated to the impartial place. Members had been inspired to carry out a observe sport earlier than the precise trial began. Every participant performed one set of every sport, and after every sport, the members might see their scores and trophies earlier than shifting on to the following sport.
2.2.2 Gaze stability VOR X 1 pitch and yaw (daring escape rehabilitation sport)
Members carried out VOR workout routines whereas sitting with an IMU connected to the brow. The app software program was preset to realize 20 levels of head vary of movement from the midline, set at a frequency of 1 Hz, and a length of 1 min. VOR workout routines had been began within the yaw airplane, adopted by the pitch airplane, utilizing the identical parameters. Modifications within the head vary of movement had been related to a change within the motion of the character on the display screen (measured by the IMU). Equally, the angular velocity setting of head movement managed the pace at which the obstacles appeared on the display screen. This pace was calculated utilizing the vary of movement and the specified angular velocity to set the variety of head rotations that wanted to be made per second. Within the “app” situation, members managed a personality on the pill display screen by shifting the pinnacle from left to proper (yaw) or up and down (pitch) to keep away from obstacles. Cash had been awarded for every impediment that was averted. Members obtained visible and auditory suggestions from the app in the event that they had been shifting their heads too far, too quick, or in the event that they made jerky head actions. All members accomplished the VOR video games within the yaw and pitch instructions at stage 2 mode, which was a visually complicated ocean-themed background (Determine 1A). Within the “no app” situation, a letter was mounted to the wall, and the participant was instructed to maneuver their head within the yaw and pitch airplane for 1 min; nonetheless, no further cues had been offered.

2.2.3 Weight shift (treasure hunter rehabilitation sport)
Members carried out weight-shifting workout routines in three instructions: anteroposterior, mediolateral, and omnidirectional, whereas standing behind a chair. The members carried out weight shifting in every route for two min with the IMU connected on the waist on a gait belt. Within the “app” situation, the character on the pill display screen was managed by the IMU, the place leaning ahead moved the character up, leaning backward moved the character down, and leaning left/proper moved the character sideways. Cash got as rewards if members efficiently shifted their physique weight within the route of the coin and returned it to the treasure chest. Directions got to maneuver from the ankle and keep away from bending from the hips or the knees (Determine 1B). Within the “no app” situation, the participant was instructed to shift their physique weight back and forth, back and front, and omnidirectionally for the required timeframe; nonetheless, no different cues had been offered.
2.2.4 Single-leg steadiness (balancing act rehabilitation sport)
Members carried out single-leg steadiness workout routines whereas standing with the IMU mounted on the waist. The participant carried out this sport twice: as soon as standing on the left leg and as soon as on the proper leg for 45 s in every place. Within the “app” situation, members managed the character on the pill display screen by remaining as steady as attainable whereas balancing on a platform tilted laterally primarily based on the motion of the IMU. Cash had been awarded for sustaining a stage pelvis. The members had been awarded both two, one, or zero cash relying on the diploma of tilt on the pelvis (Determine 1C). Within the “no app” situation, the participant was instructed to carry out the single-leg steadiness train on both sides; nonetheless, no cues had been offered.
2.3 Submit-exercise app analysis questionnaires
After finishing the “App” portion of the examine, members accomplished surveys to evaluate the benefit of use of the app, enjoyment of the intervention, and friendliness of the pill interface utilizing the next questionnaires:
1) Perceived Usefulness and Ease of Use Questionnaire, which evaluates the benefit of use of know-how (25).
2) Usefulness, Motivation, and Enjoyment Questionnaire to guage the usefulness, motivation, and pleasure of utilizing the app (19).
3) Person Interface Questionnaire, which evaluates the general reactions to the software program. This charges a number of reactions on a scale of 0 to 9 (with 5 being a impartial reply).
On the finish of all the session, members had been requested open-ended questions: (1) describe the optimistic facets as you carried out the workout routines within the app, (2) describe the damaging options as you carried out the workout routines within the app, (3) What modifications would you wish to see as you carry out the workout routines within the app? and (4) Are there any limitations that will forestall you from utilizing the app at dwelling?
2.4 Information processing
On the completion of every train session (with and with out the app), uncooked IMU in addition to abstract knowledge had been encrypted and despatched securely by the app to a cloud storage database in a de-identified format. Information had been retrieved from the database and analyzed utilizing custom-written code in Python.
2.4.1 Gaze stability VOR X 1 pitch and yaw
The roll, pitch, and yaw angle of the pinnacle had been calculated utilizing the calibration trial initially of every sport because the impartial head place (the participant was requested to carry their head regular throughout calibration whereas trying on the heart of the pill display screen). This primary step of the evaluation was carried out inside the app. A peak-finding algorithm was used to determine the height left and proper head angles of every head rotation. The top vary of movement (ROM) was calculated as the common distance between consecutive peaks, and the frequency of the peaks was calculated for the yaw and pitch route.
2.4.2 Weight shift
The mediolateral (ML) and anteroposterior (AP) angles of the pelvis had been calculated utilizing the calibration trials initially of every sport because the impartial stance place. This primary step of the evaluation was carried out inside the app. Peak excursions of the pelvis had been recognized utilizing a peak-finding algorithm. The pelvis vary of movement (ROM) was calculated as the common distance between consecutive peaks, and the frequency of the peaks was calculated. This was calculated for the ML and AP instructions for the respective video games.
2.4.3 Single-leg steadiness
The mediolateral (ML) and anteroposterior (AP) angles of the pelvis had been calculated utilizing the calibration trials because the impartial stance place initially of every sport. This primary step of the evaluation was carried out inside the app. A resultant angle of the ML and AP angles was calculated to characterize the general tour of the pelvis. Peak excursions of the pelvis had been recognized utilizing a peak-finding algorithm on the resultant angle knowledge. The fluency of the pelvic movement was calculated to characterize the smoothness of the pelvic movement through the single-leg steadiness video games. Fluency was calculated utilizing strategies beforehand described (26). A bigger fluency worth signifies a smoother movement.
3 Statistical evaluation
Statistical evaluation was carried out utilizing code written in Python. Information had been examined for normality utilizing a normality check within the SciPy module that’s primarily based on D’Agostino and Pearson’s (27, 28) check that mixes skew and kurtosis to supply an omnibus check of normality. The statistical distinction between the app and no-app circumstances was examined utilizing a paired t-test with an alpha worth of 0.05 for knowledge that had been usually distributed (VOR pitch and yaw vary of movement and frequency), and a Shapiro–Wilcoxon check (non-parametric) for paired observations was used for knowledge that weren’t usually distributed (weight-shift train vary of movement and frequency for mediolateral and anterior-posterior workout routines, single-leg steadiness vary of movement and fluency).
4 Outcomes
The app was examined with 40 adults (20 ladies), imply age of 67 ± 5.7 years, with unilateral or bilateral vestibular hypofunction. The participant circulate diagram depicts the topics screened, excluded, and enrolled (Determine 2). No opposed occasions, resembling falls, had been famous throughout testing. The imply whole dizziness handicap scores had been 31.9 ± 24.5 (vary 2–100), and the imply whole actions particular steadiness confidence scores had been 78.19 ± 23.4 (vary 20–98.8).

5 Dialogue
Vestibular rehabilitation is the gold customary therapy for folks with a recognized unilateral or bilateral vestibular hypofunction. It’s an exercise-based rehabilitation program that features adaptation, habituation, and compensation parts. Sadly, on the whole, adherence to and engagement with vestibular workout routines is poor, resulting in less-than-optimal enchancment in steadiness, gait, and signs of dizziness. The goals of this examine had been to find out if performing workout routines utilizing an interactive gaming app improved the accuracy of train efficiency in comparison with typical remedy and if the gaming and interactive options of the app had the potential to extend engagement with the train program. We discovered that when the app was used to do the VOR (daring escape) workout routines, the frequency of head movement was near the prescribed frequency in comparison with with out the app. Equally, the steadiness video games, treasure hunter, and balancing act had been carried out extra constantly, as measured by diminished variance within the frequency and vary of physique movement in comparison with the no-app situation. Members discovered the video games to be attention-grabbing, the suggestions through the video games to be helpful, and the scores and trophies to be motivating. The outcomes of this examine present a characterization of train efficiency with the app compared to typical remedy and supply data on whether or not sufferers are prone to benefit from the app and use it as prescribed by a clinician.
Train apps have turn into an integral a part of rehabilitation, and know-how can present numerous advantages when included into train applications. One space the place know-how may be harnessed to help throughout vestibular workout routines is to offer suggestions throughout workout routines. Folks with vestibular hypofunction usually cease doing their workout routines as a result of they’re uncertain if they’re doing the workout routines accurately. The app incorporates machine studying algorithms to offer augmented suggestions throughout workout routines. Suggestions is an important facet of motor studying, and studying is enhanced when observe consists of a wide range of duties whereas receiving suggestions (29, 30). The app offers two varieties of suggestions: first, data of efficiency, which is offered by way of express auditory and written suggestions on the pill display screen when a mistake is made; and second, data of outcomes, which is terminal suggestions concerning the purpose achieved. Multimodal suggestions is understood to extend sensory enhancement, which permits for elevated engagement (31); nonetheless, we have to contemplate the potential overload of the auditory and visible suggestions channels. Primarily based on the suggestions obtained from members, studying the visible suggestions through the VOR workout routines was troublesome; subsequently, additional research that particularly goal one of the best suggestions mode on this affected person inhabitants are required.
Different apps at the moment obtainable in the marketplace have used suggestions to extend engagement throughout vestibular rehabilitation. VestAid makes use of a metronome to offer suggestions on the pace of head actions and gives a gamified suggestions mode with rewards to maintain sufferers engaged, motivated, and compliant with remedy; nonetheless, it doesn’t present real-time suggestions through the workout routines on accuracy of efficiency (22). VertiGenius offers auditory suggestions utilizing a metronome throughout gaze stabilization workout routines and offers real-time visible suggestions throughout gaze stabilization workout routines by way of a visitors mild system. Members discovered the visible suggestions, within the type of the visitors mild system, useful as a result of it corrected the frequency of head motion throughout workout routines (23). The VestRx doesn’t use a metronome; as an alternative, the frequency of head motion is entered by the clinician within the app portal, and the app presents the obstacles to attaining the prescribed frequency.
We noticed that the suggestions offered allowed members to appropriate the errors made. In a earlier examine, we recognized errors that had been generally made throughout VOR workout routines (24). Machine studying algorithms had been educated to determine these errors and supply auditory and written suggestions explicitly stating the kind of error being made. Twenty-one p.c of members corrected their errors after they used the suggestions offered by VestRx for VOR pitch workout routines, in comparison with solely 10% who corrected errors within the no-app situation. Within the yaw airplane, 44% of members corrected errors throughout app use in comparison with 18% who corrected their errors within the no-app situation. The chance to appropriate errors can enhance the accuracy of workout routines, enhance engagement, and inspire sufferers to enhance their scores. General, utilizing the app elevated the accuracy of the daring escape VOR workout routines the place the frequency of head movement was near the prescribed frequency of 1 Hz and the variability of head movement was decreased; nonetheless, the vary of head movement was considerably smaller within the yaw airplane in comparison with the prescribed 20 levels in every route from midline. Primarily based on this commentary, the algorithms have been re-calibrated to make sure that head motion vary is elevated within the yaw and pitch planes through the daring escape sport. Equally, the vary and frequency of pelvic movement through the treasure hunter weight-shift sport confirmed much less variability and a decrease frequency of pelvic movement, indicating that members had been shifting in a deliberate method and holding the end-of-range positions for an extended time period. These positions are most difficult for sufferers; subsequently, they’re often rushed by way of. The app offers the required suggestions to carry these troublesome positions for an extended time.
Expertise additionally has nice potential to extend engagement and motivation to carry out workout routines, as we’ve got seen within the responses to the open-ended questions and the questionnaires used within the examine. Valenzuela et al. (21) have proven that technology-based interventions have greater adherence charges because of the reported enjoyment of utilizing these applications, indicating that enjoyment is essential to creating a profitable program. Understanding the limitations and motivators in every affected person inhabitants offers a greater understanding of their particular must create apps which might be personalised for them, as indicated by Schootemeijer et al. (32). The wants of individuals with vestibular hypofunction are distinctive. Driving to and from the clinic can enhance signs of dizziness; subsequently, having the choice to make use of the app for home-based workout routines is essential to them. VOR workout routines, that are prescribed to lower signs of dizziness and gaze instability, can inherently enhance signs additional; subsequently, driving dwelling after performing a vestibular session within the clinic could also be troublesome. Having the choice to do the workout routines at dwelling with common monitoring by the vestibular therapist can scale back a few of these limitations. The VestRx can be utilized to prescribe individualized workout routines, and the response to the workout routines may be monitored remotely to switch the prescription. The VVAS is constructed into the app as a sliding scale from 0 to 10 to be accomplished earlier than and after every VOR train. Though the VVAS was not used for this examine, our subsequent step is to trial the app within the affected person’s dwelling and use the VVAS for distant monitoring to alter the train prescription primarily based on the affected person’s response to the workout routines.
General, we discovered that members loved utilizing the app; they had been unbiased with utilizing the app within the lab setting and reported that the app would assist them do the workout routines at dwelling. It was attention-grabbing to notice that just a few members reported that doing the workout routines within the app made them anxious; subsequently, schooling concerning the totally different options and video games within the app is important to lowering their fears. Members offered detailed suggestions on the video games, the graphics, limitations, and facilitators to utilizing the app. The suggestions obtained might be included into the following iteration of the app, and the limitations described to utilizing the app at dwelling might be thought of within the home-based train trial, which might be performed subsequent.
5.1 Limitations
One limitation of the examine is that the workout routines weren’t individualized for every affected person. Our goal was to find out if utilizing the app modifications the accuracy and efficiency of workout routines; subsequently, the examine was designed to offer equivalent workout routines with the identical parameters of frequency and length. The participant group was heterogenous, with a wide range within the DHI, ABC, and VVAS scores. Due to this fact, the depth of workout routines might have been too simple for some and too troublesome for others. Members had been randomized to start out with both the app or no-app circumstances; nonetheless, these members who used the app first might have carried out higher within the no-app situation. Future research inspecting the impact of corrective lenses whereas performing workout routines are wanted since sufferers might change how they transfer their heads when carrying glasses, which can be detected as an error by the ML algorithm. The ML algorithms might should be re-trained for individuals who put on glasses and are a part of our ongoing efforts to extend the sensitivity of the app to deal with the wants of a bigger inhabitants. One other limitation of the model of the app used for this examine is the usage of the IMU, which requires folks to retailer, cost, and accurately place it on their our bodies. Our persevering with examine consists of exploring video-based marker-less movement seize to cut back limitations to compliance as a result of {hardware} necessities.
6 Conclusion
Using know-how to offer vestibular rehabilitation workout routines for people with uncompensated unilateral or bilateral hypofunction holds nice potential. The sport-based app, VestRx, has an interactive storyline, partaking characters, and motivating components resembling scores and trophies. Using the app improved the efficiency of vestibular rehabilitation workout routines, and express suggestions offered through the session enabled members to appropriate the errors they made. Though these options can enhance motivation and engagement with workout routines, different elements resembling discovering the time to do the workout routines, not seeing rapid outcomes, and remembering to do the workout routines should be thought of. Offering schooling on the significance of workout routines, limiting the length of the workout routines, and recommending methods to alleviate the rise in signs can additional enhance adherence and scale back fears related to vestibular workout routines.
