Description: This study examined the effects of inspiratory muscle training with a threshold resistive breathing device at two inspiratory loads. Twenty two patients with moderate to severe chronic obstructive pulmonary disease were randomly assigned to one of two treatment groups. One group (n = 10) exercised their inspiratory muscles with a threshold resistive breathing device at a load equal to 30% of their individual maximal inspiratory pressure (PImax) and the other group (n = 12) exercised their inspiratory muscles with the same device at a load equal to 15% of their individual PImax. Both groups exercised for 30 minutes daily for two months and dependent variables were measured: at baseline, after 1 month and after 2 months of exercises. Patients' mean age was 64 years (SD = 6) and mean forced expiratory volume in one second was 31% predicted (SD = 3.4). Patients in the 30% group improved significantly in inspiratory muscle strength (PImax), respiratory muscle endurance (sustainable inspiratory pressure endurance time), and general exercise tolerance (distance walked in 12 minutes), where patients in the 15% group improved in only PImax (p < .01). There were no changes in either group for patients' report of functional impairment (Sickness Impact Profile), moods (Profile of Moods State), health status (Health Perceptions Questionnaire), and pulmonary symptoms (respiratory symptom log). There were no changes in pulmonary function tests. These findings suggest that certain patients with COPD with benefit from inspiratory muscle training if the exercise load is appropriate. Nurses and other health professionals should consider this when managing pulmonary rehabilitation for COPD patients. But many questions remain unanswered and further research is needed in this area.
