ANS: A
With biofeedback, a patient can learn to gain conscious control over bodily responses thought to be beyond voluntary command. Listening to the monitoring device makes the patient aware of whether or not the mental exercises, breathing, or other techniques being used are effective. The machine is only needed early in therapy. Muscle relaxation and emotions have a role to play but are not the only significant factors to be considered.
