ABSTRACT
Objective. The Tuck Jump Assessment (TJA), a clinical plyometric assessment, identifies 10 jumping and landing technique flaws. The study objective was to investigate TJA interrater and intrarater reliability with raters of different educational and clinical backgrounds. Methods. 40 participants were video recorded performing the TJA using published protocol and instructions. Five raters of varied educational and clinical backgrounds scored the TJA. Each score of the 10 technique flaws was summed for the total TJA score. Approximately one month later, 3 raters scored the videos again. Intraclass correlation coefficients determined interrater (5 and 3 raters for first and second session, resp.) and intrarater (3 raters) reliability. Results. Interrater reliability with 5 raters was poor (ICC = 0.47; 95% confidence intervals (CI) 0.33-0.62). Interrater reliability between 3 raters who completed 2 scoring sessions improved from 0.52 (95% CI 0.35-0.68) for session one to 0.69 (95% CI 0.55-0.81) for session two. Intrarater reliability was poor to moderate, ranging from 0.44 (95% CI 0.22-0.68) to 0.72 (95% CI 0.55-0.84). Conclusion. Published protocol and training of raters were insufficient to allow consistent TJA scoring. There may be a learned effect with the TJA since interrater reliability improved with repetition. TJA instructions and training should be modified and enhanced before clinical implementation.

Mentions: The TJA was performed using instructions from a previously published TJA study by the developers of the test [8]. Initial set up for the TJA required 2 two-dimensional video cameras (Sony Handycam, Sony Corporation, San Diego, CA and JVC camcorder JVC Americas Corporation, Wayne NJ) on tripods to provide sagittal and frontal views of the participants. Two pieces of masking tape were placed on the ground, parallel to each other 8 inches apart. Participants were instructed to stand with one foot on each tape strip to ensure proper positioning for the cameras (Figure 1). The participants were instructed in purpose and protocol of TJA test which included: jumping repeatedly for 10 seconds with high effort level, bringing knees up as high as possible so both thighs were parallel with the ground, landing softly in the same footprint (2 pieces of tape) with each jump, and then immediately begin the next jump. No feedback was given to participants while performing the assessment. After 10 seconds, participants ceased jumping and cameras stopped recording.
