Abstract
A dynamometer which makes an angular movement is described. The dynamometer enables the measurement of the extension torque of the lower leg at different knee angles during static and slow concentric and eccentric contractions of the quadriceps femoris muscle. The influence of gravity on the measured torque signal can be compensated for by another signal representing the angular movement. The application of the dynamometer is demonstrated by giving an example of measurement.
摘要
本文描述了一种可进行角向运动的测力计。该测力计能够在股四头肌静态、缓慢向心收缩和离心收缩过程中，测量不同膝关节角度下小腿的伸展扭矩。重力对测量扭矩信号的影响可通过另一个表示角向运动的信号进行补偿。通过给出一个测量示例来展示该测力计的应用。
