“…Unfortunately, Moore used only one PEFR measurement per week, a frequency which allows no reliable conclusions to be drawn regarding either the immediate or long-term effects of relaxation on pulmonary functioning (4). Van Lith et al (5) studied the effect of deep hypnotic relaxation upon total respiratory compliance in 24 subjects with obstructive lung disease. They found no significant differences in compliance between the trance and normal awake states.…”

Clinical experience has often suggested that having asthmatic patients sit quietly and/or relax during asthma attacks is helpful. The present study was an attempt to provide a controlled experimental demonstration of the effect of systematic relaxation on peak expiratory flow rate in asthmatic children. Eighteen male and 18 female asthmatic children were divided into two groups matched for mean age, sex composition and asthma severity. One group of subjects underwent three sessions of modified jacobsonian systematic relaxation training, while the second group sat quietly for three sessions. Peak expiratory flow rate measures were obtained prior to and following each session. It was found that relaxation subjects manifested a significant mean increase in peak expiratory flow rate over sessions compared to a nonsignificant mean peak expiratory flow decrease for control subjects. It was suggested that these results have important implications both for the clinical treatment and the understanding of bronchial asthma.Physicians often ask asthmatic patients to rest or to sit quietly at the onset of and/or during an asthma attack. Patient report and clinical evidence both indicate that such a procedure often helps to mollify or alleviate wheezing. Experience at the Children's Asthma Research Institute and Hospital (CARIH) suggests that some asthmatic children do benefit from purposeful nonexertion during attacks. Likewise, clinical observations at CARIH suggest that many asthmatics suffer disadvantages from the reciprocal situation -ie, that exertion can sometimes precipitate or aggravate asthma at-

BackgroundAsthma is a chronic disease of inflammation and smooth muscle dysfunction, including bronchoconstriction. These symptoms are usually associated with widespread but variable airflow obstruction that is o en reversible either spontaneously or with treatment. Psychological factors may influence the symptoms and management of asthma in children in many ways, for example, evidence suggests that emotional stress can either precipitate or exacerbate both acute and chronic asthma. ObjectivesTo assess the e icacy of psychological interventions in improving health and behavioural outcomes for children with asthma. Search methodsThe Cochrane Airways Group Specialised Register and PsycINFO were searched with pre-defined terms up until April 2007. Selection criteriaRandomised controlled trials published in any language assessing the e ects of a psychological intervention compared with a control intervention in children and adolescents with asthma were included in the review. Cross-over trials were considered inappropriate for studies using psychological interventions and were therefore excluded from this systematic review. Data collection and analysisTwo reviewers assessed the relevance of abstracts identified by electronic searching and retrieved agreed studies for further scrutiny. The studies that met the inclusion criteria were assembled and data extracted. Main resultsTwelve studies (588 children) were included in the review. Study quality was poor and sample sizes were frequently small. A meta-analysis was possible on two studies only examining the e ects of relaxation therapy on PEFR which favoured the treatment group (32 L/min, 95% CI 13 to 50 L/min). No other meta-analysis could be performed due to the diversity of interventions and the outcomes assessed. In addition, many studies reported insu icient data.
