Trial summary

Individuals with bronchiectasis exhibit productive cough and recurrent lung infections as well as reduced exercise capacity, physical activity level, and respiratory and peripheral muscle strength. 6-minute walk test (6MWT) is often used to assess exercise capacity in chronic lung diseases.

About this study

Official title: Comparison of Cardiopulmonary Responses to 6-Minute Stepper Test Between Individuals With Bronchiectasis and Healthy Controls

Individuals with bronchiectasis exhibit productive cough and recurrent lung infections as well as reduced exercise capacity, physical activity level, and respiratory and peripheral muscle strength. 6-minute walk test (6MWT) is often used to assess exercise capacity in chronic lung diseases. 6MWT is recommended to be performed along a flat corridor, at least 30 m long, with low pedestrian traffic, on a hard surface. To overcome technical limitations during 6MWT, 6-minute stepper test (6MST) has been proposed to assess exercise capacity. Another test that provides information about exercise capacity is the 1-minute sit-to-stand test (1STS). To our knowledge, there is limited information about different exercise tests including 6MST and 1STS and cardiopulmonary responses to these tests in individuals with bronchiectasis. Therefore, this study aims to compare the responses to the 6MST between individuals with bronchiectasis and healthy controls and to investigate the relationships among 6MST, 6MWT, and 1STS responses and muscle strength.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximal inspiratory pressure

    Maximal inspiratory pressure (MIP) and will be measured using aa mouth-piece pressure measurement device. The measurement will be repeated three times so that there will be no difference of 10 cmH₂O or 10%, and the highest value will be used for analysis.

    Measured: 1st day

  2. Maximal expiratory pressure

    Maximal expiratory pressure (MEP) and will be measured using a mouth-piece pressure measurement device. The measurement will be repeated three times so that there will be no difference of 10 cmH₂O or 10%, and the highest value will be used for analysis.

    Measured: 1st day

  3. Peripheral muscle strength

    Peripheral muscle strength will be assessed using a portable dynamometer. The peripheral muscle strength test will be repeated three times for the right and left sides.

    Measured: 1st day

  4. 6-minute stepper test responses

    6-minute stepper test will be performed, and the number of repetitions will be recorded. Cardiopulmonary responses before and after 6-minute stepper test will be recorded. 6-minute stepper test will be performed twice with 30 minutes apart.

    Measured: 1st day

  5. 1 minute sit-to-stand test responses

    1 minute sit-to-stand test will be performed and the repetitions will be recoded. Cardiopulmonary responses will be recorded before and after the test.

    Measured: 1 minute sit-to-stand test will be performed and the repetitions will be recoded. Cardiopulmonary responses will be recorded before and after the test.

  6. 6-minute walk test responses

    6-minute walk test will be performed, and the distance walked will be recorded. Cardiopulmonary responses before and after 6-minute walk test will be recorded.

    Measured: 1st day

Secondary outcomes (8)
  1. Dyspnea

    The modified Medical Research Council (mMRC) dyspnea scale will be used for dyspnea assessment. The mMRC dyspnea scale is a scale in which individuals choose the expression that best describes their dyspnea level from among 5 expressions related to shortness of breath. The higher the degree, the more severe the shortness of breath.

    Measured: 1st day

  2. Charlson Comorbidity Index

    Charlson Comorbidity Index (CCI) will be used to query accompanying comorbidities. Higher CCI scores indicate a greater burden of comorbid conditions.

    Measured: 1st day

  3. Bronchiectasis Severity Index

    Bronchiectasis Severity Index will be used to evaluate disease severity and prognosis in bronchiectasis. It is calculated by respiratory function, age, chronic colonization with Pseudomonas aeruginosa and other bacterial infections, shortness of breath and radiological extent of the disease. Based on Bronchiectasis Severity Index, bronchiectasis severity is defined as mild (0-4), moderate (5-8) and severe (≥9).

    Measured: 1st day

  4. Forced vital capacity

    Pulmonary function test using a spirometer will be performed. Forced vital capacity will be recorded.

    Measured: 1st day

  5. Forced expiratory volume in one second

    Pulmonary function test using a spirometer will be performed. Forced expiratory volume in one second will be recorded.

    Measured: 1st day

  6. Forced expiratory volume in one second/forced vital capacity ratio

    Pulmonary function test using a spirometer will be performed. Forced expiratory volume in one second/forced vital capacity ratio will be recorded.

    Measured: 1st day

  7. Peak expiratory flow

    Pulmonary function test using a spirometer will be performed. Peak expiratory flow will be recorded.

    Measured: 1st day

  8. Forced mid-expiratory flow (FEF25-75)

    Pulmonary function test using a spirometer will be performed. Forced mid-expiratory flow (FEF25-75) will be recorded.

    Measured: 1st day

Questions about this trial

What is this clinical trial studying?

An observational study of Bronchiectasis Adult and Healthy Controls Group - Age and Sex-matched, run by Hacettepe University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?

Contact Aslihan Cakmak-Onal Study Principal Investigator, PhD, PT (+903123051576, aslihancakmak90@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximal inspiratory pressure (time frame: 1st day). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
