Reliability of physical performance tests for the upper extremity and trunk using telehealth in athletes

Physical performance tests (PPTs) are commonly used in in-person evaluations, with the rater setting up, supervising, and demonstrating the proper execution of the tests. However, some situations require physical distancing, and it is unknown whether those tests via telehealth are reliable. Therefore, the purpose of this study was to evaluate the reliability of upper extremity and trunk PPTs using telehealth in athletes.

Fifty-four athletes (27 male and 27 female athletes; mean age of 25.30 ± 6.20 years) were included in this study. The inter-session reliability of the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST), Line Hops Test, and the Prone and Side Bridge Test via telehealth was verified. Reliability was assessed with intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimum detectable change (MDC).

CKCUEST showed good reliability, with SEM and MDC₉₅ of 1.68 and 4.66repetitions, respectively. Line Hops Test showed good reliability, with SEM and MDC₉₅ ranging from 6.12 to 7.46 s and 16.95-20.69 s, respectively. Side Bridge Test showed good to excellent reliability, with SEM and MDC₉₅ ranging from 7.46 to 9.46 s and 20.69-26.22 s, respectively. Prone Bridge Test showed excellent reliability, with SEM and MDC₉₅ of 17.13 and 47.48 s, respectively.

Upper extremity and trunk PPTs using telehealth were considered reliable to assess athletes. The use of PPTs via telehealth may be a reliable alternative when social distancing is required, and clinicians should consider the SEM and MDC₉₅ for interpreting PPTs scores.
