Development, validity, and test-retest reliability of a new neurocognitive functional performance test: The choice-reaction hop test.

PMID 36525740WHAT IT FOUND
The choice-reaction hop test took 21.4 seconds on average, versus 10.4 seconds for the side-hop, in 49 active adults.
Repeated one week later in 9 people, times stayed similar. It has not yet been tested in injured patients.
Key findings
01In 49 participants, the choice-reaction hop test took longer than the side-hop test: mean across 3 trials 21.4 seconds versus 10.4 seconds, and fastest trial 19.7 seconds versus 8.4 seconds.
02The two tests were moderately correlated: mean across 3 trials r = 0.681, and fastest trial r = 0.637.
03When 9 participants repeated the choice-reaction hop test one week later, times were similar: mean 22.7 seconds versus 22.8 seconds, and fastest 21.0 seconds versus 21.4 seconds.

What it does not show
The validation sample was mostly male and included only physically active adults without lower-extremity injury, so it does not show how injured patients perform. Only 9 participants completed the one-week reliability test, and the confidence intervals were wide. The reliability portion was interrupted by the pandemic and completed only after the validation arm resumed. Only the dominant limb was analyzed, so non-dominant limb performance was not reported. The test requires a computer, monitor, and custom mats, so it may be less accessible than simple hop tests. No pathological populations were tested, so its usefulness for rehabilitation or return-to-sport decisions is not established.
The easy way to misread this
Do not use this test to make return-to-sport decisions for injured patients. It was validated only in physically active adults without lower-extremity injury, and the paper says pathological populations still need to be tested.
