![]() The total score had moderate interrater reliability in both sessions (Session 1: ICC 2,2 = 0.64 95% CI (Confidence Interval) (0.34-0.81) Standard Error Measurement (SEM) = 0.66 technique flaws and Session 2: ICC 2,2 = 0.56 95% CI (0.04-0.79) SEM = 1.30). RESULTSĮleven of 50 individual technique flaws were above the acceptable level (K α = 0.80). Reliability estimates were determined using intraclass correlation coefficients (ICCs) for total scores of 10 technique flaws and Krippendorff α (K α) for the individual technique flaws (ordinal). Raters used the online standardized training, scored 41 videos of participants’ TJAs, then scored them again two weeks later. ![]() Three raters of different professions: a PT, an AT, and a Strength and Conditioning Coach Certified (SCCC) were selected due to their expertise with injury and movement. ![]() The website was then validated (both face and content) by four experts. STUDY DESIGNĪ website was created by a physical therapist (PT) with videos, written descriptors of the 10 TJA technique flaws, and examples of what constituted no flaw, minor flaw, or major flaw (0,1,2) using published standards. The authors hypothesized that the total score will have moderate to excellent levels of intra- and interrater reliability. To determine the reliability of the TJA using varied healthcare professionals following an online standardized training program. Although the TJA has broad clinical applicability, there is no standardized training to maximize the TJA measurement properties. The Tuck Jump Assessment (TJA) is a test used to assess technique flaws during a 10-second, high intensity, jumping bout.
