Criteria-based return to sport, not timeframe-based. Most criteria lists include hop test symmetry, quadriceps strength ratios, and pain scores. Three good columns. Still one short.
Jiménez-Martínez et al. (2025, Frontiers in Sports and Active Living) followed ACLR athletes through completed rehabilitation programs, measuring cognition preoperatively, postoperatively, and at the end of rehab. On Multiple Object Tracking, athletes improved early in recovery, then improvement stalled. At discharge, they still showed deficits compared to healthy controls. The gap never closed.
Getting quads firing is the right focus early. Isokinetic testing confirms the muscle is there. Force testing confirms symmetry. But open-skill sport asks for more than isolated output. It asks the athlete to track multiple players, read a defense, and process spatial cues while moving. That capacity remained impaired at the completion of their rehabilitation programs.
That is the cognitive column most criteria lists are missing, and it is what Quick Board measures. Reaction time, visuomotor response accuracy, and bilateral asymmetry. Go/No-Go, Array, and Stroop tasks load inhibition, discrimination, cognitive flexibility, and decision-making, the same demands that open-skill sport places on a returning athlete.
The clip below takes it a step further. With Companion, the athlete reacts with hands and feet at the same time, upper and lower extremities working together, the way sport actually demands.
Criteria-based clearance is the right direction. The criteria list is not complete without the cognitive column.
