Respiratory Physiotherapy: Pulmonary Rehabilitation

Chronic respiratory problems significantly limit a person's ability to perform daily activities. Respiratory physiotherapy, also known as pulmonary rehabilitation, helps individuals with chronic lung conditions regain their functional abilities and improve their quality of life.

Important: Respiratory physiotherapy is a specialized service not offered at Physioactif. To access a pulmonary rehabilitation program, please consult your doctor for a referral to a hospital. This article aims to inform you about this specialty and its proven benefits.

Pulmonary rehabilitation treats various conditions such as chronic obstructive pulmonary disease (COPD), asthma, cystic fibrosis, and post-COVID respiratory issues. Programs combine supervised exercises, education, and breathing techniques.

Here's the good news: pulmonary rehabilitation significantly improves exercise capacity, quality of life, and reduces hospitalizations. Programs are now accessible remotely through telerehabilitation, eliminating geographical barriers.

What is respiratory physiotherapy?

Respiratory physiotherapy is defined as "a comprehensive intervention based on a thorough patient assessment, followed by personalized therapies" to improve the physical and psychological health of individuals with chronic respiratory diseases¹. Unlike general physiotherapy, which focuses on musculoskeletal disorders, this specialty concentrates on optimizing respiratory function.

More than 10,000 scientific articles have been published on this topic between 1960 and 2024². In 2023, the American Thoracic Society published official guidelines strongly recommending pulmonary rehabilitation for several respiratory conditions³.

This specialty is one of many physiotherapy specialties that have developed to meet specific patient needs. Unlike musculoskeletal physiotherapy, which focuses on disorders of the muscular and skeletal systems, respiratory physiotherapy exclusively addresses problems of the respiratory system.

The multidisciplinary team includes respirologist doctors, specialized physiotherapists, respiratory therapists, psychologists, nutritionists, and social workers¹. Programs take place in hospital centers equipped to monitor patients. Specialized equipment and close medical supervision ensure the safety of individuals with severe lung diseases.

What conditions are treated in pulmonary rehabilitation?

Pulmonary rehabilitation was initially developed for COPD, but its use has expanded to several other conditions¹.

COPD (Chronic Obstructive Pulmonary Disease)

COPD is the condition for which the benefits are best documented. The American Thoracic Society issues a strong recommendation (moderate quality evidence) for pulmonary rehabilitation in adults with stable COPD³.

A 2024 systematic review demonstrated that pulmonary rehabilitation after hospitalization for COPD exacerbation reduces rehospitalizations by 52%⁴. Exercise capacity improves by an average of 57 meters in the 6-minute walk test⁴, far exceeding the clinically significant threshold.

The British Thoracic Society recommends initiating rehabilitation within one month of hospital discharge after an exacerbation¹.

Asthma

Although asthma is primarily managed with medication, pulmonary rehabilitation helps individuals whose asthma limits their activities. Breathing control techniques reduce anxiety related to shortness of breath and improve symptom management.

Contrary to popular belief, well-supervised exercise does not worsen asthma and can improve long-term symptom control.

Cystic Fibrosis

Cystic fibrosis produces thick mucus that obstructs the airways, making airway clearance techniques essential. A comprehensive Cochrane review analyzed several approaches⁵, including conventional chest physiotherapy, the active cycle of breathing, autogenic drainage, PEP therapy, oscillating devices, and exercise⁵.

According to patients, the most effective methods combine active breathing techniques with a PEP device⁶. Respiratory physiotherapy for cystic fibrosis is a lifelong management approach, with daily practice to reduce exacerbations and slow progression⁵.

Post-COVID Conditions

The pandemic has created a new population requiring respiratory rehabilitation. Individuals suffering from long COVID experience persistent shortness of breath, fatigue, and reduced exercise capacity, even several months after infection.

A 2025 meta-analysis of randomized trials demonstrated that pulmonary rehabilitation improves physical capacity, lung function, quality of life, fatigue, dyspnea, and anxiety in long COVID patients⁷. Significant improvements appear after 4 to 8 weeks⁷.

A 2024 study found that home breathing exercises (four times a week for four weeks) improve respiratory function and reduce fatigue⁸.

Other Conditions

Rehabilitation benefits individuals with interstitial lung diseases (strong recommendation)³ and pulmonary hypertension (conditional recommendation)³. Programs are also used before and after lung transplantation.

What breathing techniques are used?

Breathing techniques are a central component of pulmonary rehabilitation.

The Active Cycle of Breathing Techniques (ACBT) is a structured set of exercises designed to improve lung function, clear airways, and enhance oxygenation⁹. This technique alternates between controlled breathing, chest expansion, and effective coughing.

Autogenic drainage uses different levels of breathing to move secretions towards the larger airways. This technique requires more practice to learn but allows for independent airway clearance without equipment.

PEP therapy (Positive Expiratory Pressure) uses a device that creates resistance during exhalation, keeping the airways open and making it easier to move mucus. PEP devices are popular because they can be used at home⁶.

Oscillating devices (Flutter, Acapella) combine positive pressure and vibrations to help loosen mucus. These portable devices offer a convenient option for airway clearance between sessions.

Diaphragmatic breathing and pursed-lip breathing are two fundamental techniques. Diaphragmatic breathing improves breathing efficiency. Pursed-lip breathing slows down the breathing rate and reduces air trapping.

No single technique is superior to the others¹⁰. The choice should be individualized based on preferences, learning ability, and personal effectiveness.

How does a pulmonary rehabilitation program work?

Program Components

Exercise training is the central pillar¹, including endurance work (cycling, walking), resistance training, and flexibility exercises. The intensity is gradually adjusted.

Education teaches patients to understand their condition, recognize exacerbations, manage medications, and develop action plans¹.

Psychosocial support addresses anxiety, depression, and other mental health concerns¹. Living with constant shortness of breath can be distressing. Programs offer coping strategies and peer support.

Nutritional counseling addresses weight loss and muscle wasting, which are common in severe COPD¹. Adequate nutrition is essential to maintain the muscle strength needed for exercise and daily activities. Nutritionists assess individual caloric and protein needs and suggest strategies to optimize nutritional intake, even when shortness of breath makes meals challenging.

Duration and Frequency

Most programs last 8 to 12 weeks³, leading to clinically significant improvements. Improvements in exercise capacity (40 to 57 meters in the walking test) and quality of life (6 to 9 points on the St. George's Respiratory Questionnaire) exceed significant thresholds³.

Frequency is generally 2 to 3 sessions per week, each lasting 60 to 90 minutes. This frequency allows for adequate recovery time between sessions while maintaining consistent progress. Maintenance programs after initial rehabilitation require more than one supervised session per month to preserve the benefits gained³, although the optimal frequency is still to be determined by future research.

Delivery Methods

Traditionally, rehabilitation takes place in a hospital setting with direct supervision.

Telerehabilitation has become a viable option, especially since the pandemic. Guidelines strongly recommend offering a choice between in-center and telerehabilitation³.

Telerehabilitation eliminates geographical barriers. Currently, less than 5% of people with COPD who could benefit from rehabilitation have access to it¹¹, partly due to practical obstacles.

Hybrid models combine in-person and remote sessions, offering flexibility while maintaining direct contact.

When to seek respiratory physiotherapy?

According to guidelines, "pulmonary rehabilitation is appropriate for any stable patient with chronic lung disease limited by respiratory symptoms"¹. Shortness of breath that interferes with daily activities warrants an evaluation.

Symptoms that warrant a consultation include shortness of breath during light activities (dressing, housework), persistent fatigue, repeated hospitalizations, or a decreased quality of life.

In Quebec, access is typically through a medical referral to hospital centers. The Montreal Chest Institute of the MUHC offers a recognized program¹². The CHUM and CIUSSS also offer specialized respiratory therapy services.
