Effects of relaxation training on pulmonary mechanics in children with asthma.

Alexander et al. (1979) · Journal of applied behavior analysis 1979
★ The Verdict

Relaxation training calms kids with asthma but does not improve lung function, so keep medical management primary.

01Research in Context

01

What this study did

Fourteen children with severe asthma learned relaxation skills. Therapists taught slow breathing and muscle release.

The team tracked lung function before and after training. They wanted to see if relaxation opened airways.

02

What they found

Kids felt calmer, but their lungs did not work better. Peak flow and other medical scores stayed flat.

Relaxation helped mood, not breathing. Doctors still needed inhalers and meds to control asthma.

03

How this fits with other research

Calamari et al. (1987) and Sanders et al. (1989) show relaxation lowers muscle tension and anxiety in adults with intellectual disability. Same idea, different body system — it works for muscle, not lungs.

Yamada et al. (2017) seems to disagree. Breathing training raised vital capacity in panic patients. The key gap: panic clients had tight diaphragms, not clogged airways. Asthma is a medical lung disease, so breathing drills cannot fix it.

Chadwick et al. (2000) also found big drops in dental fear with applied relaxation. Again, the target was worry, not lung tissue. The pattern is clear: relaxation helps when the problem is stress; it cannot reverse asthma damage.

04

Why it matters

If a parent asks you to add relaxation for asthma, say yes for calm, but keep medical plans in place. Track anxiety, not oxygen. For clients whose problem is fear of sensations, try the panic or dental protocols that do show gains. Match the tool to the job: relaxation for stress, medicine for lungs.

03Original abstract

An experiment, designed to overcome shortcomings in previous work, was conducted to investigate the potential symptomatic benefits of relaxation training in the treatment of asthma in children. Fourteen chronic, severely asthmatic children received three sessions in which they rested quietly, followed by five sessions of relaxation training, and finally three sessions of relaxing as trained previously. Pulmonary function was assessed, in a manner far more definitive than in previous studies, before and after each session, and three additional times at 30-minute intervals thereafter. Tension in the frontales muscles, heart and respiration rates, and skin temperature and conductance were also monitored. Heart rate and to some extent muscle tension results tended to confirm the attainment of relaxed states. However, the lung function results failed to substantiate the previous, preliminary findings of a clinically meaningful change in pulmonary function following relaxation. The status of relaxation in the treatment of asthma was discussed.
