摘要

A new form of microprocessor-controlled arthrograph is described which measures stiffness parameters of the metacarpophalangeal joints of the index, middle, and ring fingers of both hands. The apparatus is simple and quick to use and gives reproducible results. The arthrograph is used to determine the reference limits for stiffness at the middle finger of the right hand in 128 normal subjects. It is found that incorporating information on the subject's finger circumference allows a much improved precision to be achieved, but the precision is not further enhanced by including details of age and sex.

描述了一种新形式的微处理器控制关节造影仪，它测量双手食指、中指和无名指掌指关节的刚度参数。该装置使用简单快捷，结果重现性好。关节镜用于确定 128 名正常受试者右手中指僵硬度的参考限值。人们发现，结合受试者手指周长的信息可以大大提高精度，但是通过包括年龄和性别的细节，精度不会进一步提高。
