The Jamar Handgrip Dynamometer is an instrument for measuring the maximum isometric strength of the hand and forearm muscles. The Jamar dynamometer was introduced in 1954 (Bechtol,1954). It consists of a sealed hydraulic system with adjustable hand spacings that measures handgrip force in pounds per square inch (PSI) A similar device is also marketed under the name 'Baseline'. The dynamometer is used for testing your hand grip strength and tracking improvements with strength training and during rehabilitation. See more about grip dynamometers.
