The purpose of this study was to investigate the intra-rater reliability of a new method in combination with the Nintendo Wii Balance Board (NWBB) to measure the strength of hallux flexor muscle.
Thirty healthy individuals (age: 34.9 ± 12.9 years, height: 170.4 ± 10.5 cm, weight: 69.3 ± 15.3 kg, female = 15) participated. Repeated testing was completed within 7 days. Participants performed strength testing in sitting using a wooden platform in combination with the NWBB. This new method was set up to selectively recruit an intrinsic muscle of the foot, specifically the flexor hallucis brevis muscle. Statistical analysis was performed using intra-class coefficients and ordinary least product analysis. To estimate measurement error, standard error of measurement (SEM), minimal detectable change (MDC) and percentage error were calculated.
Results indicate excellent intra-rater reliability (ICC = 0.982, CI = 0.96-0.99) with an absence of systematic bias. SEM, MDC and percentage error value were 0.5, 1.4 and 12 % respectively.
This study demonstrates that a new method in combination with the NWBB application is reliable to measure hallux flexor strength and has potential to be used for future research and clinical application.
本研究旨在探讨一种新方法与任天堂 Wii 平衡板（NWBB）相结合测量大脚趾屈肌力量的内部信度。
30 名健康个体（年龄：34.9±12.9 岁，身高：170.4±10.5cm，体重：69.3±15.3kg，女性=15）参与了这项研究。重复测试在 7 天内完成。参与者采用木制平台与 NWBB 相结合的坐姿进行力量测试。这种新方法旨在选择性地招募足部的内在肌肉，特别是短屈肌。使用组内相关系数和普通最小二乘法分析进行统计分析。为了估计测量误差，计算了测量误差的标准误（SEM）、最小可检测变化（MDC）和百分比误差。
结果表明，内部测试者的信度非常高（ICC=0.982，CI=0.96-0.99），不存在系统偏差。SEM、MDC 和百分比误差值分别为 0.5、1.4 和 12%。
这项研究表明，与 NWBB 应用相结合的新方法可靠地测量大脚趾屈肌力量，并且有可能用于未来的研究和临床应用。
