Abstract
Research ObjectivesTo determine the reliability of three physical performance tests performed via a telehealth visit (30-second arm curls test, 30-second chair stand test, 2-minute step test) among community-dwelling older Veterans.DesignCross sectional study.SettingVirtual.ParticipantsVeterans (mean age 75) who enrolled in Gerofit, virtual group exercise program.InterventionsN/A.Main Outcome MeasuresParticipants were tested by two different assessors at one time point. The Interclass Correlation Coefficient (ICC) with 95% confidence intervals (CIs) and Bland-Altman plots were used as measures of reliability. To assess generalizability, ICCs were further evaluated by health conditions (type 2 diabetes, arthritis, obesity, and depression).ResultsAssessments were conducted among 55 participants. The ICC was above 0.98 for all three tests across health conditions and Bland-Altman plots indicated that there were no significant systematic errors in the measurement.ConclusionsThe virtual physical performance measures appear to have high reliability and the findings are generalizable across health conditions among Veterans. Thus, they are reliable for evaluating physical performance in older Veterans in virtual settings.Author(s) DisclosuresThe authors declare no conflict of interest.
