Background: People with Parkinson’s disease experience numerous barriers to exercise participation at fitness facilities. Advances in tele-monitoring technologies create alternative channels for managing and supervising exercise programmes in the home. However, the success of these programmes will depend on participants’ perceptions of using the technology and their exercise adherence. Thus, this pilot explored the uptake and implementation of two common methods of Internet-exercise training in Parkinson’s disease. Methods: Twenty adults with Parkinson’s disease were randomized into either: telecoach-assisted exercise (TAE) or self-regulated exercise (SRE) groups. Both groups received the same eight-week exercise prescription (combined strength and aerobic exercise) and telehealth system that streamed and recorded vital signs and exercise data. TAE participants exercised under a telecoach’s supervision via videoconferencing. SRE participants independently managed their exercise training. Quantitative data were described and qualitative data underwent thematic analysis. Results: Quantitative results demonstrated that TAE participants achieved strong attendance (99.2%), whereas SRE participants demonstrated 35.9% lower attendance, 48% less total time exercising, and 74.5% less time exercising at moderate intensity. Qualitatively, TAE participants reported overtly favourable programme experiences and that assistance from a telecoach enhanced their exercise motivation. SRE participants noted several challenges that impeded adherence. Conclusion: Findings demonstrate that adults with Parkinson’s disease acknowledge benefits of exercising through a telehealth system and are open to utilizing this channel as a means of exercise. However, human-interactive support may be required to overcome unique impediments to participation. Study findings warrant validation in larger trials that can transfer the success of TAE towards more scalable methods of delivery.

Journal of Medical Internet Research - International Scientific Journal for Medical Research, Information and Communication on the Internet #Preprint #PeerReviewMe: Warning: This is a unreviewed preprint. Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn. Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period. Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author). Background: People with Multiple Sclerosis (MS) face varying levels of disability and symptoms, thus requiring highly trained therapists and/or exercise trainers to design personalized exercise programs. However, for people living in geographically isolated communities, access to such trained professionals can be challenging due to a number of barriers associated with cost, access to transportation and travel distance. Generic mHealth exercise apps often fall short of what people with MS need to become physically active (i.e., exercise content that has been adapted to accommodate a wide range of functional limitations). Objective: This usability study describes the development process of the TEAMS (Tele-Exercise and Multiple Sclerosis) app, which is being used by people with MS in a large randomized controlled trial (RCT) to engage in home-based telerehabilitation. Methods: Twenty-one participants with disabilities (10 people with MS) were involved in the double iterative design, which included the simultaneous development of the app features and exercise content (exercise videos and articles). Framed within a user-centered design (UCD) approach, the development process included two stages: ground-level creation (focus group followed by early stage evaluations and developments), and proof of concept through two usability tests. Usability (effectiveness, usefulness, and satisfaction) was evaluated through a mixed methods approach. Results: Regarding app effectiveness, the second usability test resulted in an average of one problem per participant, a decrease of 53% compared to the initial usability test. Five themes were constructed from the qualitative data that related to usefulness and satisfaction: high perceived confidence for app usability, positive perceptions of exercise videos, viable exercise option at home, orientation and familiarity required for successful participation, and app issues. Participants acknowledged that the final app was ready to be delivered to the public after minor revisions. After including these revisions, the project team released the final app that is being used in the RCT. Conclusions: A multi-level user-centered development process resulted in an inclusive exercise program for people with MS operated through an easy-to-use app. The promotion of exercise through self-regulated mHealth programs requires a stakeholder-driven approach to app development. This ensures that app and content match the preferences and functional abilities of the end user (i.e., people with varying levels of MS).

Background: This review explored the sustainability of health and physical activity-based outcomes following exercise trials that were conducted for people with disabilities, and characterised the influence of technology and behaviour change strategies. Methods: A total of 132 studies were screened from an existing database. Results: Only 22 studies featured follow-up periods and met eligibility criteria. At follow-up, studies typically reported at least one significant health outcome that was maintained (n = 18/21; 86%). However, significant health outcomes accounted for only 32% of the total volume of outcomes that were measured at follow-up. For physical activity-based outcomes, six studies (n = 6/8; 75%) reported that intervention gains were maintained throughout follow-up. The incorporation of technology or behaviour change strategies appeared to be linked with sustainable intervention effects. Conclusions: Overall, some evidence demonstrated that post-intervention effects were sustainable. However, the strength of the evidence was weak and several existing gaps in knowledge were identified. Moreover, most studies did not focus on sustainability, but instead emphasised short-term effects of exercise participation on health and physical activity outcomes. Study findings call for greater research and programme efforts to maintain health, function, and physical activity behaviour after supports provided by research studies are removed.

Background: Access to physical activity among youth with spina bifida (SB) is much lower than it is for children without disability. Enjoyable home-based exercise programs are greatly needed. Objective: Our objective is to examine the feasibility of a virtual reality (VR) active video gaming system (ie, bundle of consumer-available equipment) to meet US physical activity guidelines in two youth with SB. Methods: Two youth with SB—a 12-year-old female and a 13-year-old male; both full-time wheelchair users—participated in a brief, 4-week exercise program using a popular VR head-mounted display: Oculus Quest (Facebook Technologies). The system included a Polar H10 (Polar Canada) Bluetooth heart rate monitor, a no-cost mobile phone app (VR Health Exercise Tracker [Virtual Reality Institute of Health and Exercise]), and 13 games. The intervention protocol was conducted entirely in the homes of the participants due to the coronavirus disease 2019 (COVID-19) pandemic. The VR system was shipped to participants and they were instructed to do their best to complete 60 minutes of moderate-intensity VR exercise per day. Exercise duration, intensity, and calories expended were objectively monitored and recorded during exercise using the heart rate monitor and a mobile app. Fatigue and depression were measured via self-report questionnaires at pre- and postintervention. Participants underwent a semistructured interview with research staff at postintervention. Results: Across the intervention period, the total average minutes of all exercise performed each week for participants 1 and 2 were 281 (SD 93) and 262 (SD 55) minutes, respectively. The total average minutes of moderate-intensity exercise performed per week for participants 1 and 2 were 184 (SD 103) (184/281, 65.4%) and 215 (SD 90) (215/262, 82.1%) minutes, respectively. One participant had a reduction in their depression score, using the Quality of Life in Neurological Disorders (Neuro-QoL) test, from baseline to postintervention, but no other changes were observed for fatigue and depression scores. Participants reported that the amount of exercise they completed was far higher than what was objectively recorded, due to usability issues with the chest-worn heart rate monitor. Participants noted that they were motivated to exercise due to the enjoyment of the games and VR headset as well as support from a caregiver. Conclusions: This study demonstrated that two youth with SB who used wheelchairs could use a VR system to independently and safely achieve exercise guidelines at home. Study findings identified a promising protocol for promoting exercise in this population and this warrants further examination in future studies with larger samples.
