title: A dynamometer for the measurement of the extension torque of the lower leg during static and dynamic contractions of the quadriceps femoris muscle.
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.
