Lachman试验是检查前交叉韧带（ACL）的手动试验之一。检查者通过感觉手指应力来判断ACL的损伤程度。研制了相应的Lachman试验测量装置。然而，这些装置的目的不是分析膝关节的应力，而是分析膝关节的运动。因此，本研究的目的是发展一套以力感测器量测Lachman测试时手指应力的量测系统。在实验中，所开发的系统被应用到12个健康的膝盖的六个科目的初学者，和一个受伤的和一个健康的膝盖的两个科目的专家。在结果中，分析了Lachman试验过程中“终点”的最大力。受试者间的变异大于受试者内的变异。未来的工作是改进手指力传感器，并适用于更多的主题，使系统可以分类到一个技能水平的考官。
Lachman test is one of manual tests for examining the anterior cruciate ligament (ACL). An examiner discreminates an injured degree of the ACL by feeling finger stress. Some measurement devices for Lachman test have been developed. However, these devices aim to analyze not the stress but a motion of the knee joint. Therefore, we set the goal of this study to develop a measurement system for the finger stress with force sensor during Lachman test. In the experiment, the developed system was applied to twelve healthy knees of six subjects by a beginner, and one injured and one healthy knee of two subjects by an expert. In the results, the maximum force of "endpoint" during Lachman test was analyzed. The variation of inter-subjects was larger than intra-subjects. Future works are to improve the finger force sensors, and to apply more subjects, so that the system could classify an examiner into a skill level.
