Background: Youth (age 15-24 years) with and without disability are not adequately represented enough in exercise research due to a lack of time and transportation. These barriers can be overcome by including accessible web-based assessments that eliminate the need for on-site visitations. There is no simple, low-cost, and psychometrically sound compilation of measures for physical fitness and function that can be applied to youth with and without mobility disabilities. Objective: The first purpose was to determine the statistical level of agreement of 4 web-modified clinical assessments with how they are typically conducted in person at a laboratory (convergent validity). The second purpose was to determine the level of agreement between a novice and an expert rater (interrater reliability). The third purpose was to explore the feasibility of implementing the assessments via 2 metrics: safety and duration. Methods: The study enrolled 19 ambulatory youth: 9 (47%) with cerebral palsy with various mobility disabilities from a children’s hospital and 10 (53%) without disabilities from a university student population. Participants performed a battery of tests via videoconferencing and in person. The test condition (teleassessment and in person) order was randomized. The battery consisted of the hand grip strength test with a dynamometer, the five times sit-to-stand test (FTST), the timed up-and-go (TUG) test, and the 6-minute walk test (6MWT) either around a standard circular track (in person) or around a smaller home-modified track (teleassessment version, home-modified 6-minute walk test [HM6MWT]). Statistical analyses included descriptive data, intraclass correlation coefficients (ICCs), and Bland-Altman plots. Results: The mean time to complete the in-person assessment was 16.9 (SD 4.8) minutes and the teleassessment was 21.1 (SD 5.9) minutes. No falls, injuries, or adverse events occurred. Excellent convergent validity was shown for telemeasured hand grip strength (right ICC=0.96, left ICC=0.98, P<.001) and the TUG test (ICC=0.92, P=.01). The FTST demonstrated good agreement (ICC=0.95, 95% CI 0.79-0.98; P=.01). The HM6MWT demonstrated poor absolute agreement with the 6MWT. However, further exploratory analysis revealed a strong positive correlation between the tests (r=0.83, P<.001). The interrater reliability was excellent for all tests (all ICCs>0.9, P<.05). Conclusions: This study suggests that videoconference assessments are convenient and useful measures of fitness and function among youth with and without disabilities. This paper presents operationalized teleassessment procedures that can be replicated by health professionals to produce valid and reliable measurements. This study is a first step toward developing teleassessments that can bypass the need for on-site data collection visitations for this age group. Further research is needed to identify psychometrically sound teleassessment procedures, particularly for measures of cardiorespiratory endurance or walking ability.

Background: The Scale-Up Project Evaluating Responsiveness to Home Exercise And Lifestyle Tele-Health (SUPER-HEALTH) initiative is a large randomized controlled study that aims to overcome logistical barriers to exercise via telehealth for people with physical disabilities. However, at the start of the COVID-19 pandemic, enrollment was halted due to limited operations at the testing site, which included no onsite visits that involved participant data collection. In response to the limited operations, a modified data collection protocol was developed for virtual enrollment of study participants. Objective: This paper presents feasibility data on using teleassessments to enroll people with mobility impairment into a home-based exercise trial. Methods: The modified protocol replaced onsite enrollment and data collection visits with teleassessments using a computer tablet and testing equipment that was shipped to the participants’ home address prior to the synchronous teleassessments conducted by an exercise physiologist through Zoom. The participants were mailed a teleassessment toolkit that included a digital blood pressure cuff, spirometer, hand dynamometer, mini disc cone, and measuring tape (to complete standardized testing). The teleassessment measures included resting blood pressure and heart rate, forced vital capacity, grip strength, Five Times Sit to Stand, and Timed Up and Go. Feasibility metrics included technological effectiveness, efficiency, and safety. The technological effectiveness of the telehealth assessment was determined by the percentage of sessions completed without technical issues with ≥90% criteria set a priori. Efficiency was measured by a session duration of ≤2 hours. Safety was measured by the number of adverse events related to the teleassessments reported. Results: Data from 36 participants were included in this feasibility study, and 34 (94%) participants completed all teleassessments without technical issues. For efficiency, the teleassessment sessions were completed in a mean time of 65 minutes and a maximum session length of 110 minutes. There were no adverse events reported to indicate concerns with the safety of teleassessments. Conclusions: The modified teleassessment protocol, in response to COVID-19 restrictions, may be a feasible process for enrolling adults with mobility impairment into a home exercise trial who otherwise would have not been able to participate.

Virtual community-based programming for people with disabilities has become a popular method for advocating for health promotion, specifically exercise, for people with disabilities (PWD). Using theoretical frameworks to better understand the perspective of PWD who participate in virtual exercise programs allows strategies of implementation following completion of virtual exercise programs. The objective of this study was to examine the effect adherence had on perceptions, experiences, and post-program exercise maintenance in participants with disabilities. Eight qualitative interviews were conducted in highly adherent participants using the Social Cognitive Theory (SCT). Interviews were recorded on Zoom, transcribed using Microsoft 365, and analyzed using NVivo software. Data were analyzed by the primary author and an independent coder to increase rigor and reduce bias. Thirty-five unique codes were generated from transcribed interviews. Member-checking was employed to increase internal validity; 100% of participants agreed with the findings. Results demonstrate an overall positive experience in the virtual exercise program, noting specific facilitators (i.e., knowledgeable instructor, program provided equipment, etc.) and barriers (i.e., limited physical space at home to exercise, other participant's attitudes, etc.) of participating. Impressionably, 100% of participants maintained exercise following their time within the virtual exercise program.

As online health and wellness programs become more ubiquitous post-pandemic, there is a need to better understand how people with physical disabilities respond to different types of program offerings. Online health promotion programs have become popular in the disability community, and programs offer a range of activities across various wellness domains (e.g., exercise, nutrition). This study examined factors predicting adherence to three different types of online health promotion programs tailored for people with physical disabilities. A survey was developed to examine factors associated with high, moderate, and low adherence to three different types of health promotion programs. Participants who completed an online wellness program were sent a survey that asked questions related to adherence to a range of wellness activities. The three programs included the MENTOR (Mindfulness, Exercise, and Nutrition to Optimize Resilience), GROWTH (Growing Resilience Out of Wellness and Thoughtful Habits), and SOSE (State of Slim Everybody) programs, all of which focus on different self-care strategies. MENTOR focused on educating participants about mindfulness, exercise, and nutrition; GROWTH aimed to deliver mental and emotional health techniques, while SOSE’s purpose was to teach participants how to implement healthy weight loss, weight management, and daily exercise practices. Results indicated that participant perceptions of program delivery, specifically programs being disability friendly, virtual environment enjoyment, having positive instructor relationships, adaptable content, the instructor’s knowledge about disability, the instructor’s use of appropriate language, and program satisfaction, affected the likelihood of high adherence among people with physical disabilities enrolled in the health and wellness programs.

Individuals with spinal cord injury often have low physical activity due to barriers such as transportation challenges, inaccessible facilities, and lack of adapted programs. Technology-enabled interventions (e.g., synchronous tele-exercise, smartphone apps, and wearable monitors) are emerging as scalable strategies to overcome these barriers. These programs are grounded in behavior-change frameworks (e.g., self-determination and social cognitive theories) and employ goal setting, feedback, and peer support to boost self-regulation skills. Recent studies indicate that supervised tele-exercise (live video-guided strength and aerobic training) is feasible and effective, yielding improved adherence and significant gains in fitness and health. Similarly, theory-driven apps and peer-coaching models have increased activity levels and reduced sedentary time. Importantly, implementation science approaches (e.g., stakeholder codesign) guide integration of these digital solutions into clinical practice. By aligning these innovations with kinesiology principles and implementation frameworks, such interventions can substantially enhance exercise participation in the spinal cord injury population.
