- Conditions
- Asthma
- Interventions
- Other: inspiratory muscle training
- Registration Number
- NCT01727765
- Lead Sponsor
- University of Portsmouth
- Brief Summary
This is a pilot study which will assess the feasibility of a follow on main study. This study will examine the impact of inspiratory muscle training on quality of life, rescue drug medication usage, and other markers of asthma in adult asthmatics in the UK.

Group Intervention Description Experimental inspiratory muscle training 6 weeks of inspiratory muscle training, 6 days per week. The intensity of training will be equivalent to up to 50% of pre-training maximal inspiratory mouth pressure and will be adapted weekly to reflect the improvement in inspiratory muscle strength Sham Comparator inspiratory muscle training 6 weeks of sham inspiratory muscle training, 6 days per week. The intensity of training will be equivalent to 5% of pre-training inspiratory mouth pressure throughout the 6 week period.
- Primary Outcome Measures
Name Time Method Maximal Inspiratory Mouth Pressure (MIP) pre (after the 4 week run-in) and post 6 weeks of IMT MIP is a surrogate measure of inspiratory muscle strength and was measured pre and post 6 weeks of either experimental or sham inspiratory muscle trianing (IMT).
