Lachman试验是检查前交叉韧带（ACL）的手动试验之一。医务人员通过手指上的压力感觉来辨别ACL损伤的程度。这种方法是主观的，依赖于医务人员的技能。为此，研制了一种用于Lachman试验的测量装置。该测量系统由手指支架和每个手指上的力传感器组成。然而，由于系统的低精度，已经提出了通过针对不同手指厚度校准手指支架来改进当前设备。对器械进行的校准成功检测了施加到手指支架上的真实力。然而，该系统只能以高精度测量低负载。未来的工作已经在进行中，以提高A/D转换器的分辨率，并使用力传感器高精度地测量Lachman测试期间的力分布。
Lachman test is one of a manual tests for examining the anterior cruciate ligament (ACL). A medical personnel discriminates degree of the ACL injury by the feeling of stress on the finger. This method is subjective and dependent on the skill of medical personnel. Hence, a measurement device for Lachman test has been developed. This measurement system consists of finger braces and force sensors on each fingers. However due to low accuracy of the system, improvement of current device has been proposed by calibrating the finger braces for different finger thickness. The calibration made for the device was successfully detect the true force applied to the finger braces. Nevertheless, the system was only able to measure low load with high accuracy. Future works are already in progress to improve the resolution of A/D converter and to measure the force distribution during Lachman test with high accuracy using the force sensor.
