|Condition or disease||Intervention/treatment|
|COPD Dyspnea Hyperinflation||Behavioral: Twice daily practice of device-guided slow breathing.|
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||11 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Device-guided Slow Breathing in COPD Patients With Clinically Significant Dyspnea: Phase 2|
|Study Start Date :||January 2011|
|Primary Completion Date :||December 2011|
|Study Completion Date :||December 2011|
|Experimental: Device-guided slow breathing||
Behavioral: Twice daily practice of device-guided slow breathing.
Participants are asked to use the slow-breathing device for 20 minutes twice daily, for 8 weeks. Participants receive weekly telephone calls to monitor device use and are encouraged to use pursed-lips when following the breathing tones of the device while exhaling.
- Determine effect of increased device-guided breathing on health-related quality of life measures. [ Time Frame: 8 weeks ]Pre and post device use measures of dyspnea, health-related quality of life, stress, adn self-efficacy for managing chronic disease will be obtained through self-administered questionnaires.
- Evaluate effect of device-guided slow breathing on daily physical activity. [ Time Frame: 8 weeks ]Evaluate the effect of a higher intensity of device-guided breathing (20 minutes twice daily for 8 weeks) on daily physical activity, as measured by a gold-standard activity monitor, before and after device use.
