This study evaluated and validated the reliability of smartphones as measuring equipment for the dorsi-plantar flexion of ankle joint position sense (JPS) ability.
The subjects were 20 healthy young students in their 20s. We confirmed the concurrent validity by comparison with existing electrogoniometer data. The reliability of the smartphone was confirmed using the test-retest method.
In the case of dorsiflexion, there was no significant difference between the smartphone and electrogoniometer groups ( > 0.05). Regarding the correlation, it was significantly high ( = 0.65, < 0.05), and ICC(3,1) was good (ICC(3,1) = 0.79). For the case of plantar flexion, there was no significant difference between the smartphone and electrogoniometer groups (p > 0.05), the correlation was significantly high ( = 0.69, < 0.05), and the ICC(3,1) was very good (ICC(3,1) = 0.82). In the case of dorsiflexion, there was no significant difference between test and retest ( > 0.05), the correlation was intermediate ( = 0.59, < 0.05), and the ICC(3,1) value was good (ICC(3,1) = 0.74). For plantar flexion, there was no significant difference between test and retest ( > 0.05), the correlation was significantly high ( = 0.63, < 0.05), and the ICC(3,1) was good (ICC(3,1) = 0.76).
The results showed that smartphones provide high validity and reliability as measurement equipment for JPS of dorsi-plantar flexion of the ankle. Finally, the study also considers that smartphone-based JPS measuring methods may replace the traditional and expensive methods that are currently being used for the same purpose.
本研究评估并验证了智能手机作为踝关节背屈位置觉（JPS）能力测量设备的可靠性。
研究对象为20名20多岁的健康青年学生。通过与现有电子角度计数据进行比较来确认同时效度。使用重测法确认智能手机的可靠性。
在背屈情况下，智能手机组和电子角度计组之间无显著差异（>0.05）。就相关性而言，其显著较高（=0.65，<0.05），且组内相关系数（ICC(3,1)）良好（ICC(3,1)=0.79）。对于跖屈情况，智能手机组和电子角度计组之间无显著差异（p>0.05），相关性显著较高（=0.69，<0.05），且ICC(3,1)非常好（ICC(3,1)=0.82）。在背屈情况下，测试和重测之间无显著差异（>0.05），相关性中等（=0.59，<0.05），且ICC(3,1)值良好（ICC(3,1)=0.74）。对于跖屈，测试和重测之间无显著差异（>0.05），相关性显著较高（=0.63，<0.05），且ICC(3,1)良好（ICC(3,1)=0.76）。
结果表明，智能手机作为踝关节背跖屈JPS的测量设备具有较高的效度和可靠性。最后，该研究还认为基于智能手机的JPS测量方法可能会取代目前用于相同目的的传统且昂贵的方法。
