Abstract

Explore qualitative differences between interventions (DVD and booklet (DVDB) versus face-to-face and booklet (F2FB) versus usual care) in the BREATHE (Breathing Retraining for Asthma Trial of Home Exercises) trial of breathing retraining for asthma. Quantitative process analysis exploring group expectancy, experience and practice before and after intervention delivery for the main trial. Primary care. Adults with asthma (DVD and booklet, n = 261; F2FB, n = 132). Baseline - expectancy about breathing retraining; follow-up 3, 6 and 12 months - self-efficacy, treatment experience (enjoyment of treatment, perceptions of physiotherapist, perceptions of barriers), amount of practice (weeks, days/week, times/day), continued practice; all time points - anxiety (Hospital Anxiety and Depression Scale), AQLQ (Asthma Quality of Life Questionnaire). No group differences in baseline expectancy. Statistically significant results (P < 0.05) indicated that at follow-up, F2FB participants perceived greater need for a physiotherapist than DVD and booklet participants (3.43 (0.87) versus 2.15 (1.26)). F2FB participants reported greater enjoyment of core techniques (such as stomach breathing: 7.42 (1.67) versus 6.13 (1.99) (DVD and booklet)). Fewe...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
