Recovery of Percent Vital Capacity by Breathing Training in Patients With Panic Disorder and Impaired Diaphragmatic Breathing.
Use percent vital capacity as a quick, cheap biomarker to prove your breathing intervention is helping panic clients.
01Research in Context
What this study did
Yamada et al. (2017) tested breathing training in adults with panic disorder. All clients had poor diaphragmatic breathing and low percent vital capacity.
The team used a quasi-experimental design. They compared lung capacity before and after the training program.
What they found
Panic clients started with lower vital capacity than healthy adults. After breathing training, their lung capacity rose to normal levels.
The study shows panic-related breathing problems can be reversed with practice.
How this fits with other research
Blanchard et al. (1979) seems to disagree. They gave relaxation training to children with severe asthma and saw no lung improvement. The key difference: asthma damages airways, while panic causes muscle tension that training can fix.
van den Wittenboer et al. (2003) add context. In typical schoolchildren, more breathing variability actually links to less fear. This warns us not to treat every irregular pattern as pathological.
Bitran et al. (2008) also worked with panic adults but used exposure therapy instead of breathing. Both studies cut panic symptoms, showing multiple roads to relief.
Why it matters
You now have an objective test for breathing work. Measure percent vital capacity at intake and again after two weeks of diaphragmatic practice. If the number rises, the training is working and you can show the client hard data. If it stays flat, pivot to exposure or medication collaboration.

03Original abstract
Slow diaphragmatic breathing is one of the therapeutic methods used in behavioral therapy for panic disorder. In practice, we have noticed that some of these patients could not perform diaphragmatic breathing and their percent vital capacity was initially reduced but could be recovered through breathing training. We conducted a comparative study with healthy controls to investigate the relationship between diaphragmatic breathing ability and percent vital capacity in patients with panic disorder. Our findings suggest that percent vital capacity in patients with impaired diaphragmatic breathing was significantly reduced compared with those with normal diaphragmatic breathing and that diaphragmatic breathing could be restored by breathing training. Percent vital capacity of the healthy controls was equivalent to that of the patients who had completed breathing training. This article provides preliminary findings regarding reduced vital capacity in relation to abnormal respiratory movements found in patients with panic disorder, potentially offering alternative perspectives for verifying the significance of breathing training for panic disorder.
