The Quick Board computerized agility training system is able to measure differences in affected leg reaction time over time; the change in the affected leg on the Quick Board correlated with changes on the SFT hop testing.
Readiness for return to sport following anterior cruciate ligament reconstruction (ACLR) is a multifactorial assessment. Standard Functional Testing (SFT) is an established tool for evaluation of rehabilitation status following ACLR. It is known that agility, in the form of reaction time, correlates with the risk of soft tissue injury following ACLR, but current tools for assessing rehabilitation status, including SFT, do not readily evaluate reaction time. The Quick Board computerized agility training system has demonstrated improved agility in a well patient population; it’s efficacy as a rehabilitation assessment tool has yet to be established, but could add to other assessment tools by providing an evaluation of reaction time.
Hypothesis/Purpose: (1) Quick Board single and double leg reaction time correlates with SFT results on the operative and non-operative legs. (2) Overall reaction time will improve in the operative patient population following a Neuromuscular Re-Education (NMR) program.
This was a retrospective study involving (30) patients enrolled in our institution’s 6 week NMR program that is conducted for interested patients following standard post-op ACLR rehabilitation. The program is conducted six months following ACLR. Only patients who had participated in the NMR program following ACLR, and completed pre and post testing, were included in the study population. Pre and post testing included SFT hop tests (Single Leg, Timed Hop, Triple Hop, Crossover Triple Hop) as well as single leg and double leg reaction time on the QuickBoard. The Quick Board records the speed of foot touches on a sensor mat placed on the floor; the participant touches the sensors in a similar pattern for each test. The results were recorded for affected leg and unaffected leg. The change from pre to post testing in the affected leg was then compared between SFT hop tests and Quick Board results to determine if the Quick Board testing demonstrated similar findings to the SFT hop testing results.
The Quick Board single leg reaction time test demonstrated a significant difference in pre to post NMR testing for the affected leg (p=0.02), and no significant difference in the unaffected leg (p=0.09). Reaction time on the Quick Board double leg reaction test also improved significantly from pre to post testing (p<0.01). For all four SFT hop tests there was a statistically significant improvement for the affected leg (p<0.01) as well. There is a significant correlation between the Quick Board and SFT results in terms of improvement on the affected leg.
The Quick Board computerized agility training system is able to measure differences in affected leg reaction time from beginning to completion of an NMR program, and demonstrates an improvement in affected leg reaction time. The change in the affected leg over time on the Quick Board correlated with changes on the SFT hop testing. Quick Board agility training may be an effective assessment tool to include following ACLR rehabilitation.
