Standardized test procedures are proposed that may be used by instrument manufacturers, investigators, and testing agencies to specify the functional characteristics of biofeedback devices. The test procedures are intended for EMG, EEG, and EKG feedback devices. Included are procedures for the specification of electrode characteristics, input impedance, noise, common-mode rejection ratio (CMRR), filter characteristics, time constant, battery life, and characteristics of the feedback signal. A variety of novel test procedures are currently being used to specify biofeedback instrument functional characteristics. Adoption of common test procedures will improve comparability of equipment, technical specification sheets, and apparatus technical descriptions in research reports.
