In order to determine the best course of action for asthma patients, studies regarding various methods have been conducted. The one being explored in today’s post looks at inspiratory muscle training (IMT) tested on female patients as a means to improve dyspnea and reduce gender differences in patients with asthma.
- Women with asthma have lower respiratory strength, more severe perceived dyspnea and higher bronchodilator consumption.
- After 20 weeks of RMT, the gender differences in respiratory muscle strength, dyspnea scores and bronchodilator use disappeared.
RMT effectively improves respiratory strength, dyspnea and bronchodilator consumption in female asthma patients.
Maximal inspiratory mouth pressure (PImax) was measured in male and female asthma patients. Female patients underwent IMT with increasing resistance until their inspiratory muscle strength had reached that of male counterparts. Perception of dyspnea (POD) and bronchodilator use were recorded throughout the duration of the study.
At the end of 20 weeks of IMT, PImax – and thus, the muscle strength of all female asthma patients – was equal to that of male counterparts. At that point in time, the differences in POD and bronchodilator consumption disappeared.
IMT significantly improves the inspiratory muscle strength measured by PImax. Increasing the inspiratory muscle strength of women with asthma reduces the higher severity of asthma in women to the severity level of male patients, with equal perception of dyspnea and bronchodilator use.
