[Purpose] A goniometer is frequently used for static measurement of hindfoot alignment. However, although goniometer measurements require experience, their reliability and validity remain controversial. We developed a hindfoot alignment measurement method by laser as an alternative measure. The purpose of this study was to examine the reliability of laser-assisted hindfoot alignment evaluation. [Participants and Methods] Two non-expert examiners (without medical knowledge), briefly trained in the use of laser-assisted hindfoot alignment evaluation, evaluated hindfoot alignment in 12 healthy participants. [Results] The ICC of the intra-rater reliability was 0.74 for both examiners and the ICC for inter-rater reliability was 0.43. [Conclusion] The good intra-rater and moderate inter-rater reliability of laser-assisted hindfoot alignment evaluation, when used by non-professionals, suggest the laser-assisted hindfoot alignment evaluation may be appropriate for use in clinical practice settings.
[目的] 测角器常用于后足对线的静态测量。然而，尽管测角器测量需要经验，但其可靠性和有效性仍存在争议。我们开发了一种激光辅助的后足对线测量方法作为替代测量手段。本研究的目的是检验激光辅助后足对线评估的可靠性。[参与者与方法] 两名未经专业培训（无医学知识）但经过激光辅助后足对线评估简要培训的检查者，对12名健康参与者的后足对线进行评估。[结果] 两位检查者的组内相关系数（ICC）均为0.74，组间相关系数为0.43。[结论] 非专业人员使用激光辅助后足对线评估时，组内可靠性良好，组间可靠性中等，这表明激光辅助后足对线评估可能适用于临床实践环境。
