The structure and functions of a depth-sense esthesiometer have been described. Unlike the prototype designed by Renfrew, the new instrument is so fabricated that the speed and the directions of its movements, and the pressure applied by the finger, can be constantly controlled. In addition, it provides an automatic measurement of depth-sense thresholds with greater accuracy. Thirty-three normal subjects and nine patients were examined with both instruments. With the new esthesiometer all normal hands, as expected, showed normal results, but, with the Renfrew instrument, 12 of these 66 hands (18%) showed abnormal results. Similarly, on examination of the hands of the nine patients, the new instrument showed equally improved reliability.
已对深度觉测量仪的结构和功能进行了描述。与伦弗鲁设计的原型不同，新仪器的制造使得其移动速度和方向以及手指施加的压力能够得到持续控制。此外，它能更精确地自动测量深度觉阈值。用这两种仪器对33名正常受试者和9名患者进行了检查。正如预期的那样，使用新的测量仪时，所有正常的手都显示出正常结果，但是，使用伦弗鲁仪器时，这66只手中有12只（18%）显示出异常结果。同样，在对9名患者的手进行检查时，新仪器也显示出可靠性同样有所提高。
