Older adults’ experiences of internet-based vestibular rehabilitation for dizziness: A longitudinal study

A gaming app developed for vestibular rehabilitation improves the accuracy of performance and engagement with exercises

Introduction

Vestibular hypofunction is associated with dizziness, imbalance, and blurred vision with head movement. Vestibular rehabilitation is the gold standard recommendation to decrease symptoms and improve postural stability. The Clinical Practice Guidelines for vestibular hypofunction suggest home exercises 3-5 times daily, but patient adherence is a problem, with compliance rates often below 50%.

Methods

An app was developed to increase engagement with home exercises by providing exercises as games. This study compared the accuracy of exercise performance in a one-time session using the app versus no-app and gathered participant feedback on using the app for vestibulo-ocular reflex (VOR) and balance exercises. The app was tested with 40 adults (20 women), mean age of 67 ± 5.7 years, with symptomatic unilateral or bilateral vestibular hypofunction. Participants completed VOR exercises in pitch and yaw planes, weight-shift, and single-leg balance exercises using an inertial motion unit to move the character on the tablet screen. Participants were randomly assigned to begin the exercises with or without the app.

Results

Results show that during VOR exercises, participants achieved the prescribed frequency of head motion for the yaw plane (p ≤ 0.001) and reduced variability of head movement frequency in both the yaw (p ≤ 0.001) and pitch plane (p ≤ 0.001) in the app compared to the no-app condition. During weight-shifting exercises, a larger range of body motion was noted in the anteroposterior and mediolateral directions in the app compared to the no-app condition (p < 0.05). During single-leg balance exercises, pelvic motion was lower in the app versus no-app condition (p = 0.02). Participants modified their exercise performance and corrected their mistakes to a greater extent when they used the app during the VOR exercises. Participants agreed that they felt motivated while playing the games (97%) and felt motivated by the trophies (92%). They agreed that the app would help them perform the exercises at home (95%), improve their rehab performance (95%) and that it was fun to do the exercises using the app (93%).

Discussion

The results of this study show that technology that is interactive and provides feedback can be used to increase accuracy and engagement with exercises.

Factors that influence the provision of home-based rehabilitation services for people needing rehabilitation: a qualitative evidence synthesis

BACKGROUND

To increase people's access to rehabilitation services, particularly in the context of the COVID-19 pandemic, we need to explore how the delivery of these services can be adapted. This includes the use of home-based rehabilitation and telerehabilitation. Home-based rehabilitation services may become frequently used options in the recovery process of patients, not only as a solution to accessibility barriers, but as a complement to the usual in-person inpatient rehabilitation provision. Telerehabilitation is also becoming more viable as the usability and availability of communication technologies improve.

OBJECTIVES

To identify factors that influence the organisation and delivery of in-person home-based rehabilitation and home-based telerehabilitation for people needing rehabilitation.

SEARCH METHODS

We searched PubMed, Global Health, the VHL Regional Portal, Epistemonikos, Health Systems Evidence, and EBM Reviews as well as preprints, regional repositories, and rehabilitation organisations websites for eligible studies, from database inception to search date in June 2022.  SELECTION CRITERIA: We included studies that used qualitative methods for data collection and analysis; and that explored patients, caregivers, healthcare providers and other stakeholders' experiences, perceptions and behaviours about the provision of in-person home-based rehabilitation and home-based telerehabilitation services responding to patients' needs in different phases of their health conditions.   DATA COLLECTION AND ANALYSIS: We used a purposive sampling approach and applied maximum variation sampling in a four-step sampling frame. We conducted a framework thematic analysis using the CFIR (Consolidated Framework for Implementation Research) framework as our starting point. We assessed our confidence in the findings using the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach.  MAIN RESULTS: We included 223 studies in the review and sampled 53 of these for our analysis. Forty-five studies were conducted in high-income countries, and eight in low-and middle-income countries. Twenty studies addressed in-person home-based rehabilitation, 28 studies addressed home-based telerehabilitation services, and five studies addressed both modes of delivery. The studies mainly explored the perspectives of healthcare providers, patients with a range of different health conditions, and their informal caregivers and family members.  Based on our GRADE-CERQual assessments, we had high confidence in eight of the findings, and moderate confidence in five, indicating that it is highly likely or likely respectively that these findings are a reasonable representation of the phenomenon of interest. There were two findings with low confidence. High and moderate confidence findings Home-based rehabilitation services delivered in-person or through telerehabilitation  Patients experience home-based services as convenient and less disruptive of their everyday activities. Patients and providers also suggest that these services can encourage patients' self-management and can make them feel empowered about the rehabilitation process. But patients, family members, and providers describe privacy and confidentiality issues when services are provided at home. These include the increased privacy of being able to exercise at home but also the loss of privacy when one's home life is visible to others.  Patients and providers also describe other factors that can affect the success of home-based rehabilitation services. These include support from providers and family members, good communication with providers, the requirements made of patients and their surroundings, and the transition from hospital to home-based services. Telerehabilitation specifically Patients, family members and providers see telerehabilitation as an opportunity to make services more available. But providers point to practical problems when assessing whether patients are performing their exercises correctly. Providers and patients also describe interruptions from family members.  In addition, providers complain of a lack of equipment, infrastructure and maintenance and patients refer to usability issues and frustration with digital technology. Providers have different opinions about whether telerehabilitation is cost-efficient for them. But many patients see telerehabilitation as affordable and cost-saving if the equipment and infrastructure have been provided. Patients and providers suggest that telerehabilitation can change the nature of their relationship. For instance, some patients describe how telerehabilitation leads to easier and more relaxed communication. Other patients describe feeling abandoned when receiving telerehabilitation services.  Patients, family members and providers call for easy-to-use technologies and more training and support. They also suggest that at least some in-person sessions with the provider are necessary. They feel that telerehabilitation services alone can make it difficult to make meaningful connections. They also explain that some services need the provider's hands. Providers highlight the importance of personalising the services to each person's needs and circumstances.

AUTHORS' CONCLUSIONS

This synthesis identified several factors that can influence the successful implementation of in-person home-based rehabilitation and telerehabilitation services. These included factors that facilitate implementation, but also factors that can challenge this process. Healthcare providers, program planners and policymakers might benefit from considering these factors when designing and implementing programmes.

The Quality, Reliability, and Popularity of YouTube Education Videos for Vestibular Rehabilitation: A Cross-sectional Study

HYPOTHESIS

Vestibular rehabilitation (VR) education videos on YouTube are poor-quality and unreliable.

BACKGROUND

YouTube has become a health information source. Recent studies have determined that videos on YouTube contain misleading and inappropriate information for different medical conditions. The aim of the present study was to assess the quality and reliability of VR education videos.

METHODS

A search was performed using the keywords vertigo, vertigo treatment, vertigo exercise, and vestibular rehabilitation, on YouTube. The first 50 videos for each keyword were analyzed. Videos were divided into four groups according to the video source: Group 1: universities/occupational organizations, Group 2: medical ad/profit-oriented companies, Group 3: independent users, and Group 4: others (news/media/state institution). The quality and reliability of videos were evaluated regarding the modified DISCERN criteria, the modified Journal of the American Medical Association (JAMA) benchmark criteria, and global quality scores (GQS).

RESULTS

Among the 200 videos analyzed, 103 were included. The main video source was medical ad/profit-oriented companies (60.2%). The mean modified DISCERN criteria score, the mean modified JAMA benchmark criteria score, and the mean GQS value of the videos were found as low (2.46 ± 1.37, 2.09 ± 1.23, and 2.67 ± 1.38, respectively). Videos uploaded by universities/occupational organizations (25.2%) had statistically significant higher modified DISCERN criteria scores, modified JAMA benchmark criteria scores, and GQS values compared with the other groups (p < 0.001).

CONCLUSION

Online information about VR education on YouTube was of poor quality and unreliable. Expert vestibular providers should be aware of these inappropriate sources and educate patients regarding the poor-quality of videos and also aim to provide more quality and reliable sources of information.

Experiences of patients and physiotherapists with blended internet-based vestibular rehabilitation: a qualitative interview study

Background

Internet-based vestibular rehabilitation (VR) with physiotherapy support, known as blended VR, was effective in reducing vestibular symptoms in a recent randomised controlled trial. Blended VR is a complex intervention comprised of physiotherapeutic visits, the vertigo training website, and VR exercises. Because of these interacting components, it is important to understand how blended VR works, for whom it works best, and how it should ideally be delivered.

Aim

To investigate the experiences of both patients and physiotherapists with blended internet-based VR.

Design & setting

A qualitative interview study was performed with patients who received blended internet-based VR with physiotherapy support, and physiotherapists who provided this support.

Method

Semi-structured interviews were conducted with 14 patients and eight physiotherapists after the 6-month follow-up of the randomised trial. All interviews were audio-recorded, transcribed, and thematically analysed.

Results

According to both patients and physiotherapists, the physiotherapist visits were useful in providing personal attention, helping patients safely execute exercises, and improving patients’ adherence to therapy. Some patients said they did not need physiotherapist support and, according to physiotherapists, both the necessity and the optimal way to deliver guidance differed greatly between patients. The Vertigo Training website and exercises provided patients with a sense of control over their symptoms. Patients reported that the VR exercises were easy to perform and most patients continued to use them long after the trial ended.

Conclusion

In blended VR, physiotherapeutic visits appear to offer benefits above the vertigo training website and VR exercises alone. Physiotherapy support may best be used when individually tailored.

Internet based vestibular rehabilitation with and without physiotherapy support for adults aged 50 and older with a chronic vestibular syndrome in general practice: three armed randomised controlled trial

OBJECTIVE

To investigate the clinical effectiveness and safety of stand alone and blended internet based vestibular rehabilitation (VR) in the management of chronic vestibular syndromes in general practice.

DESIGN

Pragmatic, three armed, parallel group, individually randomised controlled trial.

SETTING

59 general practices in the Netherlands.

PARTICIPANTS

322 adults aged 50 and older with a chronic vestibular syndrome.

INTERVENTIONS

Stand alone VR comprising a six week, internet based intervention with weekly online sessions and daily exercises (10-20 minutes a day). In the blended VR group, the same internet based intervention was supplemented by face-to-face physiotherapy support (home visits in weeks 1 and 3). Participants in the usual care group received standard care from a general practitioner, without any restrictions.

MAIN OUTCOME MEASURES

The primary outcome was vestibular symptoms after six months as measured by the vertigo symptom scale-short form (VSS-SF range 0-60, clinically relevant difference ≥3 points). Secondary outcomes were dizziness related impairment, anxiety, depressive symptoms, subjective improvement of vestibular symptoms after three and six months, and adverse events.

RESULTS

In the intention-to-treat analysis, participants in the stand alone and blended VR groups had lower VSS-SF scores at six months than participants in the usual care group (adjusted mean difference -4.1 points, 95% confidence interval -5.8 to -2.5; and -3.5 points, -5.1 to -1.9, respectively). Similar differences in VSS-SF scores were seen at three months follow-up. Participants in the stand alone and blended VR groups also experienced less dizziness related impairment, less anxiety, and more subjective improvement of vestibular symptoms at three and six months. No serious adverse events related to online VR occurred during the trial.

CONCLUSION

Stand alone and blended internet based VR are clinically effective and safe interventions to treat adults aged 50 and older with a chronic vestibular syndrome. Online VR is an easily accessible form of treatment, with the potential to improve care for an undertreated group of patients in general practice.

Factors that influence older people's engagement with digital health technology

Digital health technology (DHT) encompasses a wide range of applications and interventions with the potential to address the health needs of an increasingly ageing population. Older people's engagement with DHT depends on many factors, and this article summarises understanding of the barriers and facilitators to DHT uptake and continued use among older people. Older people's confidence in using digital technology, their perceptions of personal benefit from DHT, its design, and the support they receive from health professionals and carers in using DHT all affect their level of engagement. Understanding these barriers and facilitators among the older population creates ways to enable greater numbers to benefit from DHT. This article provides information for those who work with, or design digital health interventions for, older people to help them to influence older people's engagement with these rapidly evolving healthcare innovations.
