Brief summary of evidence supporting the efficacy of biofeedback for asthma

Lehrer et al (2004) recently performed a controlled study in which 94 asthmatics were trained (or not if they were in the control group) using heart rate variability biofeedback with excellent results. Other studies have found signs of reduced inflammation of the lungs and reduced respiratory impedance coincident with reduced symptoms (Kern-Buell, Lehrer et al., 1997; Lehrer, McGrady, Conran, & Nelson, 2000, Lehrer, Smetankin, & Potapova, 2000)
