Brief Summary

The aim of this study is to investigate asthma patients' experiences with an 8 week IMT and the perceived effects of this intervention on physical activity, coping strategies, and asthma self-management. A qualitative methodological design will be applied to understand the experiences of patients participating in the IMT program, how the program affected their daily activities, how they coped with symptoms and difficulties, and how they managed their condition.

Detailed Description

The study will include patients diagnosed with asthma by a chest disease specialist and referred for pulmonary rehabilitation. Cases meeting the inclusion criteria will be questioned about the effects of their previous experience with COPD on their daily lives, their coping strategies, and their self-management processes. Therefore, it is determined as a basic criterion that participants have received IMT training for 8 weeks, 2 days a week via video conference and 1 day within the home program, for a total of 3 days a week. IMT should be performed in 7 sets, consisting of 2 minutes of work and 1 minute of rest, for a total of 21 minutes. Five main themes were identified as a result of data analysis. (a) Inspiratory Muscle Training and Participant Experiences (b) Experience of Exercising with Telerehabilitation (c) Changes in Physical Activity Levels (d) Self-Management Skills and (e) Coping Strategies.
