Instructional, Pacing, and Feedback Control of Respiratory Behavior

Abstract

Procedures designed to affect respiration rate and amplitude were assessed for 4 groups of 8 subjects each. The groups were exposed to combinations of procedures providing feedback for decreasing respiration amplitude, pacing respiration rate, and instructions on rate and amplitude of breathing. After an initial baseline, effects were examined during both treatment and self-management phases for respiratory activity and concurrent heart-rate and electromyogram activity. Reliable effects of pacing on respiration rate, and a slight, but non-significant effect on amplitude were observed. No effects were observed for any heart-rate or electromyogram measures.
