This paper describes a new specific test to asses spatial and orientation abilities: Navigation Ability Test (NAT). The goal of this study was to determine if football players and normal subjects use vestibular information to keep track of their positions while walking through the Navigation Ability Test.
This study was conducted on a total of 120 patients undergoing Navigation Ability Test (NAT): 60 football players and 60 normal subjects were recruited on the basis of no history of vertigo/balance disorders and a negative otoneurological instrumental examination and the second group of the football players were recruited from Division B, Division Under-21 and Women's League. Patients who met the inclusion criteria were enrolled in the study.
Our results showed differences between sexes during navigation tasks are not related to spatial learning per se, but appear to be the consequence of difference in ability to effectively use specific types of distal information such as room geometry. The NAT showed that the route-times walked with eyes closed are always longer than in normal people and mistakes improve with training.
These results show that NAT could suggest to the coach and trainers valuable information about the characteristics of the players and how they should play in the field. Although there are some intrinsic difficulties, for example in creating patient-specific versions of the test, preliminary normative data indicate that this original test is workable and provides important information in therapy rehabilitation for vestibular disorder.
本文描述了一种用于评估空间和定向能力的新的特定测试：导航能力测试（NAT）。本研究的目的是确定足球运动员和正常受试者在通过导航能力测试行走时是否利用前庭信息来跟踪自己的位置。
本研究共对120名接受导航能力测试（NAT）的患者进行：60名足球运动员和60名正常受试者，他们均无眩晕/平衡障碍病史且耳神经科仪器检查结果为阴性，其中足球运动员的第二组来自乙级联赛、21岁以下联赛和女子联赛。符合纳入标准的患者被纳入研究。
我们的结果表明，导航任务期间的性别差异与空间学习本身无关，而似乎是有效利用特定类型的远端信息（如房间几何形状）的能力差异的结果。NAT显示，闭眼行走的路线时间总是比正常人长，并且错误随着训练而减少。
这些结果表明，NAT可以为教练和训练师提供有关球员特征以及他们在场上应如何表现的有价值信息。尽管存在一些内在困难，例如创建针对患者的测试版本，但初步的规范数据表明，这种原始测试是可行的，并为前庭障碍的治疗康复提供重要信息。
