To examine the intra-observer reliability and agreement between five methods of measurement for dorsiflexion during Weight Bearing Dorsiflexion Lunge Test and to assess the degree of agreement between three methods in female athletes.
Repeated measurements study design.
Volleyball club.
Twenty-five volleyball players.
Dorsiflexion was evaluated using five methods: heel-wall distance, first toe-wall distance, inclinometer at tibia, inclinometer at Achilles tendon and the dorsiflexion angle obtained by a simple trigonometric function. For the statistical analysis, agreement was studied using the Bland-Altman method, the Standard Error of Measurement and the Minimum Detectable Change. Reliability analysis was performed using the Intraclass Correlation Coefficient.
Measurement methods using the inclinometer had more than 6° of measurement error. The angle calculated by trigonometric function had 3.28° error. The reliability of inclinometer based methods had ICC values < 0.90. Distance based methods and trigonometric angle measurement had an ICC values > 0.90. Concerning the agreement between methods, there was from 1.93° to 14.42° bias, and from 4.24° to 7.96° random error.
To assess DF angle in WBLT, the angle calculated by a trigonometric function is the most repeatable method. The methods of measurement cannot be used interchangeably.
检验在负重背屈弓步试验中，五种背屈测量方法的观察者内信度及一致性，并评估女性运动员中三种方法之间的一致程度。
重复测量研究设计。
排球俱乐部。
25名排球运动员。
使用五种方法评估背屈：足跟-墙壁距离、第一足趾-墙壁距离、胫骨处倾角计、跟腱处倾角计以及通过简单三角函数获得的背屈角度。对于统计分析，使用布兰德-奥特曼方法、测量标准误差和最小可检测变化来研究一致性。使用组内相关系数进行信度分析。
使用倾角计的测量方法存在超过6°的测量误差。通过三角函数计算的角度有3.28°的误差。基于倾角计的方法的信度，其组内相关系数值<0.90。基于距离的方法和三角角度测量的组内相关系数值>0.90。关于方法之间的一致性，偏差为1.93°至14.42°，随机误差为4.24°至7.96°。
为评估负重背屈弓步试验中的背屈角度，通过三角函数计算的角度是最可重复的方法。这些测量方法不能互换使用。
