RELIABILITY AND VALIDITY OF A BATTERY OF FUNCTIONAL TESTS APPLIED BY VIDEOCONFERENCE IN ATHLETES
Telehealth, Physiotherapy, Assessment, Sports.
Introduction: Physical performance tests, also known as functional tests, offer an objective assessment of patients' physical capacity. Evidence suggests that the validity and reliability of online physical therapy assessments range from acceptable to excellent across various domains. However, the reliability and validity of a battery of synchronous physical performance tests administered via videoconference in athletes, involving upper and lower limbs, have not yet been comprehensively investigated. Objective: To evaluate the reliability and validity of a battery of synchronous physical performance tests administered remotely to athletes. Methods: Athletes of both sexes, aged 18 to 40, of varying competitive levels, affiliated with sports teams or clubs, with at least two years of practice and participation in regional and/or national competitions, will be included. Each athlete will undergo two online assessments via video call (Google Meet), spaced seven days apart, and one in-person assessment. The following tests will be administered: Closed Kinetic Chain Upper Extremity Stability Test
(CKCUEST), Modified Upper Quarter Y-Balance Test (mUQYBT), Upper Limb Rotation Test (ULRT), Modified Star Excursion Balance Test (mSEBT), One-Leg Sit-to-Stand Test (OLSTS), Single Hop Test, and Side Hop Test. Test-
retest reliability will be verified using the Intraclass Correlation Coefficient (ICC), and validity will be analyzed using Pearson's correlation coefficient (r). The standard error of measurement (SEM) and the minimum detectable difference (MDC) will also be calculated for each test. Expected results: The tests are expected to demonstrate good reliability and validity when administered via videoconference, in addition to clinically acceptable SEM and MDC values, contributing to the safe and evidence-based use of these instruments in the telehealth context.
