Premature return to play after concussion may have debilitating or even fatal consequences. Computerised neuropsychological test batteries are widely used to monitor recovery, but none meet all specified criteria. One possible alternative is to measure saccadic reaction time or latency. Latency reflects the operation of cerebral decision mechanisms, and is strongly influenced by many agents that impair cortical function. A portable, micro-miniature device (saccadometer) was used to record the eye movements of amateur boxers before and after competitive bouts. Individual latency distributions were significantly affected after blows to the head, though the effects seemed to be reversible, with recovery over a few days. This quantitative, objective and easy to use technique should perhaps be deployed more widely to evaluate its potential in monitoring the effects of sports-related head injuries.
脑震荡后过早重返赛场可能会带来使人衰弱甚至致命的后果。计算机化神经心理测试组合被广泛用于监测恢复情况，但没有一种能满足所有规定标准。一种可能的替代方法是测量眼球跳动反应时间或潜伏期。潜伏期反映大脑决策机制的运作，并且受到许多损害皮质功能的因素的强烈影响。一种便携式超微型设备（眼球跳动测量仪）被用于记录业余拳击手在比赛前后的眼球运动。头部受到击打后，个体潜伏期分布受到显著影响，不过这些影响似乎是可逆的，几天内即可恢复。这种定量、客观且易于使用的技术或许应更广泛地应用，以评估其在监测与运动相关的头部损伤影响方面的潜力。
