Determining eye-hand coordination using the sport vision trainer: an evaluation of test-retest reliability

The purpose of this investigation was to assess the number of test-retest trials required to familiarize participants in order to provide acceptable reliability for the measurement of an eye-hand coordination task using the Sport Vision Trainer (SVT). Two schedules were conducted (S1 and S2). For S1, 64 participants (male n = 51, age 20.8 ± 4.9 years; female n = 13, age 20.1 ± 2.1 years) attended four sessions each 1 week apart, and undertook four trials using the SVT. For S2, 60 participants (male n = 46, age 20.8 ± 4.9 years; female n = 14, age 20.1 ± 2.1 years) attended one 20-minute schedule consisting of four consecutive trials using the SVT. Limits of agreement (LoA) analyses showed that absolute reliability was increased in both studies. The LoA for S2 indicate that error decreased between trial 1-2, 2-3, and 3-4; ± 0.95 (CI, -1.16, +2.56sec), ± 0.97 (CI, -1.66, +2.14sec), ± 0.69 (CI, -1.08, +1.62sec). It was concluded that reliable measurements of eye-hand coordination can be obtained using the SVT in one session.
