Our Isokinetic Dynamometer: HUMAC Norm Testing & Rehabilitation System (CSMI, Stoughton, MA)
The HUMAC NORM is the latest generation of Isokinetic Dynamometers. It can be used to measure and improve human performance in the clinic, training room, and research laboratory. SInce the 1960s, these machines have developed so that this machine now offers 22 isolated-joint movement patterns, four resistance modes (isokinetic, isotonic, isometric, and passive) and will produce numerous reports to meet the measurement and exercise needs of both clinicians and researchers.
