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