“…Likewise, study findings for interrater reliability are consistent with those reported by other investigations that included older adults without disabilities [ 17 , 18 ]. Regarding modifications to the conventional 6MWT, a previous study had children with CP perform the 6MWT over 15 and 30 m courses [ 67 ]. The authors concluded that a shorter and narrower walking course could result in more turning and less straight walking paths, both of which could negatively affect or add volatility to the walking distances [ 67 ].…”

This could explain the variable differences observed between the HM6MWT and 6MWT distance results in our study.…”

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 Clinical assessments of therapeutic exercise studies are typically not designed to be translated into the home or community and fall short of reaching confirmatory study samples. OBJECTIVE The first aim was to explore the feasibility of conducting tele-assessments for early adults with and without disabilities via metrics of implementation: duration of the assessments, technical usability issues. The second aim was to establish a statistically appropriate level of agreement between the tele- and in-person exercise assessments (convergent validity). The third aim was to establish a statistically appropriate level of inter rater agreement for each tele-assessment between two independent raters. METHODS This cross-sectional study enrolled 18 people: 9 youth with disabilities from a Children’s Hospital, and 9 youth without disabilities from a University student population, which was matched for age (aged 15-24 years), sex, and weight. Participants were randomized to perform a battery of functional assessments either via tele-assessment (performed onsite at the laboratory) or via in-person supervision. Participants completed a handgrip strength test with each hand, the Five Times Sit to Stand (FTST) test, the Timed Up and Go (TUG) test, and a 6 minute-walk test (either around a standard circular track [in-person] or around a smaller home-simulated track [tele-assessment]). Descriptive analyses and intraclass correlation coefficients (ICC) were used to examine agreement between the the two types of tests and raters on the tele-assessment tests. RESULTS The mean time to complete the tele-assessment battery was 21.7 ± 5.4 and the in-person assessments was 17.3 ± 4.7 mins. Excellent descriptive and statistical agreement between tele-assesment and in-person assessments was demonstrated for hand grip strength (right ICC=0.96 ; left ICC=0.98), and the Timed Up and Go (ICC=0.96); good agreement for the FTST test (ICC=0.83). The tele-assessment 6MWT demonstrated excellent agreement (ICC=0.91) with in-person distance using a conversion factor of 10.85 meters per tele-assessment lap. However, the Bland-Altman Plot demonstrated poor agreement for the tele-assessment to either underestimate or overestimate walking distances compared to those obtained in-person. CONCLUSIONS Study findings demonstrated that a simple tele-assessment battery can be used to assess physical fitness and function among ambulatory youth with and without disabilities. The battery has strong psychometric properties, but notable limitations, which warrant further investigation. This study is a first step towards developing tele-assessments that can bypass the need for onsite data collection vistations for this age group.
