Research investigating human walking often has been focused on kinematic variables, which describe motion without regard to the forces that cause the motion. Kinetics is the study of forces that cause movement.[1,2] Understanding kinetic variables, such as moments and power, may assist in understanding the mechanical causes of movement and how these movements might best be enhanced.[2]
A joint moment has been described as a measure of the net effect of all agonist and antagonist muscle activity that causes rotation at a given joint.[1,3] Clinicians often use an isokinetic dynamometer to measure joint movements or peak torque as an indicator of muscle performance.[4]
