NCT06707623

Brief Summary

In this study the efficacy of a pulmonary rehabilitation program tailored to the needs of patients with dysfunctional breathing (DB) will be investigated using cardiopulmonary exercise testing. The pulmonary rehabilitation program will be compared with physiotherapy which is currently the mainstream therapy of DB.

    At enrolment and after 8/9 weeks (depends on study arm).

  • The Breathing Vigilance (V-Q) Questionnaire

    At enrolment and after 8/9 weeks (depends on study arm).

  • The Hospital Acquired and Depression Scale (HADS)

    At enrolment and after 8/9 weeks (depends on study arm).

Study Arms (2)

Pulmonary Rehabilitation Group

EXPERIMENTAL

Patients with Dysfunctional Breathing participating in an individualized Rehab Program that will combine exercise and breathing retraining

Other: Pulmonary Rehabilitation

Physiotherapy Group

EXPERIMENTAL

Patients with dysfunctional breathing in this group will receive respiratory physiotherapy (breathing retraining)

Other: Respiratory Physiotherapy

Interventions

Physiotherapy will include: Progressive breathing retraining, neurosensory training, nose breathing training, activity modification, inhalation-exhalation ratio training, dynamic respiratory control training and instructions for continuing all of the above training at home. Total 5 sessions in 9 weeks time.

Physiotherapy Group

Pulmonary Rehabilitation will be completed in 16 sessions (2 times a week for 8 weeks). It will combine exercise with breathing retraining guided by CPET findings regarding erratic breathing pattern and/or hyperventilation.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Dysfunctional breathing (DB) diagnosed with CPET.
  • Adult patients (\>18 years of age)
  • Able and willing to attend an outpatient multidisciplinary, supervised rehabilitation program of a total duration of two months (8 weeks).
  • Able and willing to attend 5 physiotherapy sessions over a period of 9 weeks.
  • Sign an informed consent.

You may not qualify if:

  • No underling pathology explaining dyspnea and DB in CPET (e.g normal dead space to tidal volume ratio (VD/Vt) and normal alveolar-arterial (A-a) gradient.)
  • Patients with COPD
  • Patients with uncontrolled asthma
  • Patients with post-exertional malaise (PEM).
  • Patients that cannot attend an outpatient rehabilitation program like suffering from dementia, chronically paralyzed, with paraplegia, multiple injuries, or other serious orthopaedic problems that cause disability or suffer from very serious underlying diseases such as end-stage cancer, and patients with neurological diseases that cause disability, require specialized rehabilitation clinics and special interventions (speech therapy, kinesiotherapy, etc.).
