Knee Extension Ergometers (KEE)
The Knee Extension Ergometer is widely used to investigate muscle physiology research questions, particularly peripheral limitations to maximal oxygen consumption, including impaired endothelial-dependent vasodilation, muscle fiber atrophy, capillary rarefaction, and altered metabolic function.

The Technavance KEE platform incorporates a NIST-traceable calibrated load cell, optical encoder, magnetic switch, and photomicrosensors to deliver highly accurate measurements across a wide range of experimental parameters. A proprietary, web-based user interface enables researchers to communicate directly with the instrument, reporting both instantaneous and averaged values for rate of work, force, cadence and technique efficiency. Up to eight measured variables can be exported or streamed directly to third-party data acquisition systems. The interface also provides visual and auditory feedback to promote consistent subject effort during experimental protocols.
Technavance offers two KEE models to support different experimental needs: the KEE 1000, which supports unilateral exercise, and the KEE 2000, which supports both unilateral and bilateral exercise.
