Hospital Practice, 1998
Physicians have long recognized that therapeutic effects of pharmacologically inactive agents can be a complicating factor in medical research. Not only pills but also other features of the physician-patient encounter may recruit the healing response. Deliberate use of the placebo response may improve both patient satisfaction and treatment efficacy.

Placebo effects influence symptom perceptions and treatment outcomes. Placebo effects can be explored in laboratory settings controlling for natural history and expectations. Such a mechanistic approach to neurological disorders has been implemented in the domain of chronic clinical pain and other neurological disorders.
