About

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).

Full 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.

Enrollment: 34 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Certain diagnosis of non-CF bronchiectasis (chest HRCT)
• Over 18 years old, clinically stable in the previous 6 weeks (no need for antibiotic therapy due to exacerbations) and a dyspnea score over 1 according to the modified Medical Research Council (mMRC) dyspnea scale

Exclusion criteria

• Less of 18 years
• Other airway disease ( Asthma or COPD)
• Physical inability to perform a physical training program (neuromuscular pathology or residual injuries).
• Smokers or former smokers of less than 6 months or with a history of consumption of 15 packs/year.
• Cystic fibrosis.
• Active infections (bronchopulmonary aspergillosis, pulmonary tuberculosis).
• Active tuberculosis.
• Medical illnesses that put the individual at risk of a decompensation due to the performance of any physical activity or cardiopulmonary stress test (unstable ischemic heart disease, acute myocardial infarction less than 1 month).
• Pregnancy
• Mental disorder that prevents the adequate interpretation of the indications or performance of the tests.
• Attended pulmonary rehabilitation within 1 year.

34 participants in 2 patient groups

Pulmonary rehabilitation home-based program intervention group (PRHP)(IG)

Experimental group

Description:

Participants were given two hospital sessions: in the first session the physiotherapist explained the exercises to be performed at home and there was a reminder session at 4 weeks. Reminder call was carried out weekly for 8 weeks. The patients were advised to do the exercises at least 3 times a week. The number of times they performed physical activity and its duration were recorded in a questionnaire

Treatment:

Other: Pulmonary rehabilitation home-based program intervention group (PRHP)(IG)

Control group

No Intervention group

Description:

Participants received general written advice and recommendations for physical activity
