Clinical Trial Summary

A number of studies have described low exercise capacity and physical activity in patients with non-cystic fibrosis bronchiectasis (non-CF Bronchiectasis), although little research exists on using the cardiopulmonary exercise test (CPET) to evaluate exercise capacity and its most relevant changes after a pulmonary rehabilitation home-based program (PRHP). In addition, few studies have addressed tolerance to exercise and physical activity in severe cases of the disease. Aims: To evaluate the exercise capacity of non-CF BQ patients using CPET and physical activity after a pulmonary rehabilitation home-based program. Methodology: Our study describes a non-pharmacological clinical trial in non-CF BQ patients at the Virgen Macarena University Hospital (Seville, Spain). The patients were randomized into two groups: the control group (who were provided with training instructions) and the intervention group (who took part in a specific pulmonary rehabilitation home-based program).

Description:

A signed informed consent form was provided prior to inclusion in the study. The data evaluated was obtained under strict confidentiality rules. All patients passed an initial assessment of the degree of physical activity by means of accelerometers, as well as pulmonary function tests and exercise tolerance (CPET) and 6MWT, stratification severity according to the E-FACED scales, quality of life using the saint george respiratory questionnaire.

Eligibility

Inclusion Criteria:

• Certain diagnosis of non-CF bronchiectasis (chest HRCT)

Intervention

Other:
• Pulmonary rehabilitation home-based program intervention group (PRHP)(IG)
The strength training program included upper and lower limb exercises, initially with no weights but progressively adding weights once a week depending on symptoms, in 2 sets with 6-8 repetitions, for at least 5 days a week. The exercises recommended were the 'hanger' (which exercises the latissimus dorsi muscle), 'butterfly' (pectoralis major muscle), 'neck press' (triceps brachii and deltoids), leg flexion (biceps femoris and gastrocnemius) and leg extension (quadriceps femoris). As resistance training, patients could choose between walking or cycling 3 to 5 days per week, for at least 20 minutes, increasing the duration of the exercise weekly, depending on their symptoms
