Study summary

Pain mechanisms and their clinical impact in patients with bronchiectasis have not been investigated yet. The aim of the research is to assess the presence of central pain mechanisms in patients with bronchiectasis using the Quantitative Sensory Testing (QST) assumptions.

Read the detailed description

Background and objective:

Recent findings suggest that pain can play an important role in terms of physical activity limitation in respiratory patients. Nevertheless, pain mechanisms and their clinical impact in patients with bronchiectasis have not been investigated yet. The objective of the observational study is to determine the somatosensorial profile in order to assess the presence of central pain mechanisms in patients with bronchiectasis.

Methodology:

Repeated-measures prospective cross-sectional study. A sample of patients diagnosed with bronchiectasis will be recruited and matched by age and sex with healthy controls. Pressure pain thresholds (PPTs), conditioned pain modulation (CPM) and referral pain will be assessed before and after the Incremental Shuttle Walking test (ISW). Levels of physical activity will be assessed using accelerometry during a 7-days period. Sleep quality (Pittsburgh sleep quality test), level of catastrophizing (Pain Catastrophizing Scale), level of sensitization (Central Sensitization Inventory) and level of anxiety and depression (Hospital Anxiety and Depression) will be assessed. The assessments will be done twice: 1) at baseline; and 2) at 6 months follow-up period.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Referred pain area

    Amount of pixels painted in an electronic body chart (Navigate Pain, Aalborg, Denmark) after supra threshold pain stimulus (STPS) in infraspinatus muscle.

    Time frame: Baseline

Secondary outcomes

  1. Number of body areas affected by referred pain

    Body chart is divided in 15 regions and the frequency of pain in each one is registered after STPS

    Time frame: Baseline

  2. Pain intensity after supra threshold pain stimulus (STPS)

    Level of pain in a visual analogue scale from 0 to 10 after STPS

    Time frame: Baseline

  3. Pressure pain thresholds (PPTs)

    Level of pressure tolerated by the patient just before feel pain. The pressure is done with an algometer (SB-MEDIC Electronics, Solna, Sweden). PPTS will be assessed bilaterally in infraspinatus, supraspinatus and medial gastrocnemius muscles.

    Time frame: Baseline

  4. PPTs with a Conditioned Pain Modulation (CPM) pressure stimulus

    Level of pressure tolerated by patient just before feel pain. The conditionated pressure stimulus is preform by a blood pressure cuff. CPM will be assessed bilaterally in infraspinatus, supraspinatus and medial gastrocnemius muscles.

    Time frame: Baseline

  5. Total physical activity time

    Total time spent per day in physical activities at different intensities equal or superior to 100 counts per minute (≥100 cpm), obtained by accelerometry (Actigraph gt3x+).

    Time frame: 7 days period

  6. Sedentary behaviour time

    Total time spent per day in physical activities at different intensities inferior to 100 cpm (\<100 cpm).

    Time frame: 7 days period

  7. Light physical activity time

    Total time spent per day in physical activities at intensities between 100 and 1951 cpm (100-1951 cpm).

    Time frame: 7 days period

  8. Moderate-Vigorous physical activity time

    Total time spent per day in physical activities at intensities equal or superior to 1952 cpm (≥1952 cpm).

    Time frame: 7 days period

  9. Level of catastrophizing

    Punctuation obtained in Pain Catastrophizing Scale (PCS). It comprises 13 items which focus on thoughts and feelings encountered while experiencing pain. Each item is scored from 0 (not at all) to 4 (all the time) with a total PCS score range from 0-52 points, where higher scores indicating higher levels of pain catastrophizing.

    Time frame: Baseline

  10. Level of sensitization

    Punctuation obtained in Central Sensitization Inventory (CSI). CSI assesses 25 health-related symptoms common to Central Sensitivity Syndromes. Responses are recorded about the frequency of each symptom, with a Likert scale from 0 (never) to 4 (always), resulting in a total possible score of 100. Higher scores are associated with a higher degree of self-reported symptomology.

    Time frame: Baseline

  11. Level of anxiety and depression

    Punctuation obtained in Hospital Anxiety and Depression (HAD). The HAD is a 14-item self-report scale measuring the presence of symptoms of both anxiety (seven items) and depression (seven items) during the past week. Each item is scored from 0 to 3, so the final score for each subscale is between 0 and 21. The majority of the studies use the cutoffs of 7/8 for possible and 10/11 for probable anxiety or depression.

    Time frame: Baseline

  12. Quality of sleep

    Punctuation obtained in Pittsburgh Sleep Quality Index (PSQI). The PSQI is a 19-item, self-rated questionnaire designed to measure sleep quality and disturbance over the past month in clinical populations. Each sleep component yields a score ranging from 0 to 3, with 3 indicating the greatest dysfunction. Sleep component scores were summed to yield a total score ranging from 0 to 21 with the higher total score (referred to as global score) indicating worse sleep quality.

    Time frame: Baseline

  13. Level of resilience

    Punctuation obtained in Brief Resilience Scale (BRS). This is a 6-item self-report scale with a 5-point response scale ranging from 1 (strongly disagree) to 5 (strongly agree). A higher score indicates a higher degree of resilience.

    Time frame: Baseline

  14. Distance in ISW test

    Meters reached in the ISW test.

    Time frame: Baseline

  15. Changes in referred pain area

    Amount of pixels painted in an electronic body chart (Navigate Pain, Aalborg, Denmark) after supra threshold pain stimulus (STPS) in infraspinatus muscle.

    Time frame: Baseline and after 6 months follow-up

  16. Changes in number of body areas affected by referred pain

    Body chart is divided in 15 regions and the frequency of pain in each one is registered after STPS

    Time frame: Baseline and after 6 months follow-up

  17. Changes in pain intensity after supra threshold pain stimulus (STPS)

    Level of pain in a visual analogue scale from 0 to 10 after STPS.

    Time frame: Baseline and after 6 months follow-up

  18. Changes in pressure pain thresholds (PPTs)

    Level of pressure tolerated by the patient just before feel pain. The pressure is done with an algometer (SB-MEDIC Electronics, Solna, Sweden)

    Time frame: Baseline and after 6 months follow-up

  19. Changes in Pressure Pain Thresholds (PPTs) with a Conditioned Pain Modulation (CPM) pressure stimulus

    Level of pressure tolerated by patient just before feel pain. The conditionated pressure stimulus is preform by a blood pressure cuff

    Time frame: Baseline and after 6 months follow-up

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 31, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
