It is now possible to reliably and accurately measure, continuously and simultaneously, body movement and physical cost (PC), emotional cost (EC), and functional pain (FP), by a new physiological process, in people performing usual tasks in their normal environment without any distortion being imposed by the measuring system. This hypothesis is tested in a small group of human subjects performing selected activities containing obviously different physical, emotional, and pain levels, and determining if the obtained PC, FC, FP values are sensitive to differences in these levels and vary in the right direction. a. Subjects are amateur hockey players and are physiologically recorded during games, with simultaneous T.V. taping, to correlate the physiological recordings with the specific activities of interest: play and rest cycles, handling puck or not, defending, fights. b. Subjects with electrical stimulation mild pain, randomly administered, are tested to determine if pain administered during rest and during various physical activities always produces an increase in the FP value.National Institute of Mental Health (NIMH)
