For the past forty years or so, the electromyograph has been used in the diagnosis and evaluation of neuromuscular disorders. Reseachers did not attempt to provide patients with feedback of the electromyographic (EMG) signals, however, until the late 1950s (Marinacci & Horande, 1960). In their excellent review of the use of EMG biofeedback in neuromuscular rehabilitation, Inglis, Campbell, and Donald (1976) speculate that the seminal work on voluntary control of visceral responses conducted by Neal Miller and colleagues in the late 1960s generated a conceptual, paradigmatic revolution among electromyographers that laid the foundation for the use of biofeedback techniques. In any case, the field of biofeedback therapy for neuromuscular rehabilitation has blossomed in the past 10 years.
