Pulmonary tuberculosis (TB) is a leading cause of mortality and morbidity worldwide. In recent years, patients with chronic respiratory diseases have been found to have a decreased quality of life. Pulmonary TB is also a significant risk factor for chronic respiratory diseases due to its effect on lung function. Although patients with pulmonary TB are considered “successfully treated” and “cured” by completing the full treatment, patients often struggle with post-TB sequelae to the lung leading to impaired functional status and decreased Quality of life. Pulmonary rehabilitation is an effective tool to improve the clinical, physical, psychosocial, and overall quality of life. This review highlights the role of pulmonary rehabilitation in patients with pulmonary TB sequelae.

| Introduction|| |
Tuberculosis (TB) is a communicable disease and is one of the top ten causes of death worldwide. Approximately 10 million people fell ill with TB in 2019.
According to the World Health Organization (WHO), India has the highest TB burden globally with an estimated incidence of 26.9 lakh cases in 2019. TB treatment saved 63 million lives globally between (2000 and 2019). The disease primarily affects the lungs (pulmonary TB) but can also affect other sites (extra-pulmonary TB). TB is an illness of poverty, socioeconomic burden, and stigma. People with pulmonary TB often suffer from lung damage, including fibrosis, cavitation, and other radiological changes, even if they are considered completed anti-TB regimen and declared cured. This can lead to loss of lung function, decreased quality of life, and physical and psychosocial impairments. They also face a substantial economic burden due to loss of wages and cost due to treatment for TB.
WHO's end TB strategy has laid out guidelines to eradicate TB by 2030. National Tuberculosis Elimination Program has laid down guidelines for a post-TB follow-up to diagnose and manage post TB sequelae. Pulmonary rehabilitation is the most effective and evidence-based tool for the optimal management of Post TB sequelae to prevent further morbidity and mortality and aims to improve the quality of life.
| Birth of Tuberculosis Rehabilitation|| |
The most famous phrases of the Roman poet Juvenal in western society, “Menssana in corporesano,” is best translated as “A healthy mind lives within a healthy body.” A sign of good health is a fit body, and exercise became an essential aspect of Greco-Roman civilization. In the olden days, rest was considered as a treatment for impaired health. In the 19th century, patients with various disorders were advised to rest in bed and were treated by nurses and healthcare professionals. Bed rest was accepted as standard therapy. Sanatoriums were established for TB patients to provide good rest, nutritious food, and fresh air.
The concept was that rest and a good nutrition program was the most effective treatment for managing TB patients to improve their immunity and control the infection. The high altitude at rest, clean air, and nourishment reached its height of acceptance as therapy. In the 18th century, the sanatorium was first introduced in Europe to treat and rehabilitate TB patients, followed by the United States of America and Canada.

The council of rehabilitation defines rehabilitation as “the restoration of the individual to the fullest medical, mental, emotional, social, and vocational potential of which he or she is capable.” Pulmonary rehabilitation has arisen as a recommended standard of care based on scientific evidence for chronic respiratory disease patients. The American Thoracic Society and the European Respiratory Society have recently adopted the following definition of pulmonary rehabilitation as a comprehensive intervention, based on a complete patient assessment followed by tailored, multidisciplinary therapy and education to improve the physical and emotional conditions of patients with chronic respiratory diseases and to promote adherence to healthy behaviors. It is one of the most cost-effective treatments for chronic respiratory diseases and improves overall quality of life and daily activities.
| Sequelae of Pulmonary Tuberculosis|| |
Patients often struggle with pulmonary TB sequelae after completion of anti-TB therapy or complete microbiological cure. Amar et al. and Visca et al. suggested that pulmonary TB infection, bronchiectasis, pneumonia, and exacerbation of chronic obstructive disease more commonly occur., It results in structural changes of the lung, including emphysema and bronchiectasis. In addition, air pollution and tobacco smoking also damage lung parenchyma from repeated infection. Post-TB sequelae can show obstructive airway disease, restrictive airway disease, or mixed defect. It is essential to know the pattern of the pulmonary abnormalities of patients. These effects progress to lung dysfunction that differs from minor breathlessness to decreased Quality of life and affects daily living. It is essential to perceive these inconveniences so as not to confuse them as continuous dynamic sicknesses. Due to significant disability of decreased quality of life and affected daily living, postpulmonary TB sequelae patients are good candidates for pulmonary rehabilitation.
| Prevalence of Postpulmonary Tuberculosis Sequelae|| |
In an observational study of TB sequelae in treated TB patients, Gohar Ali et al. found that only 11 (9%) of 155 patients had effective cures from the disease. In comparison, 91% had TB sequelae (both lung parenchymal and pleural sequelae). It indicates that TB sequelae are frequent and should be identified early after TB therapy to improve the Quality of life.
A study done by Willcox et al.; reported that in treated pulmonary TB patients, there is a high frequency of obstructive lung disease. Out of 71 people, 48 subjects (68%) who had previously been treated for TB had their pulmonary function tested for up to 16 years, and there was evidence of early airway obstruction.

There is a scarcity of studies regarding pulmonary rehabilitation in pulmonary TB sequelae. The most common treatment prescribed for this chronic disease is bronchodilator therapy, inhaled corticosteroids, and oxygen therapy. Since it affects the overall quality of life of the patient, pulmonary rehabilitation for post-TB sequelae will be a boon to mankind. Rehabilitation of post-TB sequelae involves a multidisciplinary approach. After the bacteriological cure of TB, early post-TB sequelae and implementation of PR increase the overall patient's quality of life. Singh et al. also reported a significant improvement in functional status and quality of life in their study of patients who received post-TB pulmonary rehabilitation. It is tailored individually and consists of physical exercises, breathing exercises, psychological counseling, and nutritional and educational components. It improves symptoms and the functional capacity of the lung.
| Physical Exercise|| |
The vital part of the pulmonary rehabilitation program is physical exercises that improve symptoms and physical activities of patients with chronic lung diseases. Upper limb exercise includes flexion and extension of shoulder, elbow, and arm exercises. Lower limb exercises include squats, walking, and stair-climbing, which reactivate the physical recondition. The target of physical activity consists of both upper limbs and lower limbs where minimal exercises are preferred, followed by an increase in intensity. Weights and repetition of the upper and lower exercises result in muscle strength. To achieve endurance, walking and cycling are performed. Depending on the patient's endurance, the intensity should be increased slowly. In a study, Rupert Jones et al. reported that the main focus of the rehabilitation program was aerobic lower limb exercises, which includes physical reconditioning for strengthening essential muscles to improve oxygen utilization for enhancing cardiopulmonary performance.
| Breathing Exercises and Psychological Support|| |
The program consists of breathing exercises which are deep breathing exercises, pursed-lip breathing exercises, diaphragmatic breathing exercises in a sitting position to improve the breathing discomfort. Pursed lip breathing involves active exhalation with resistance by a pursed-lip seal to produce an expiratory whistle (expiration). Expiration should be double the duration of inspiration. This type of breathing reduces airway collapse by improving lung ventilation. The diaphragmatic technique involves slow and deep inspiration by placing one hand on the chest and the other on the abdomen, projecting the abdominal wall to the outside.
The overall goal is to improve the patient's quality of life and functional ability of the lung and improve the patient's psychosocial status for successful disease management. Various psychological problems such as depression, anxiety, and stress are associated with chronic lung diseases patients, especially with TB sequelae which depletes their quality of living and well-being. Emotional support must be provided to patients during the pulmonary rehabilitation program. Patient and program results should be assessed at the end of the program and periodically after that. This assessment must compare the status of the patient before and after the rehabilitation program.
This review suggests that pulmonary rehabilitation for post-pulmonary TB sequelae is a great boon to mankind. Many of the research and TB guidelines fail to address the importance of post TB impact. TB can be prevented, the progression from infection to active illness can be stopped, and active disease can be detected and treated quickly, but the disease's impact is not considered once the treatment ends. TB survivors have a high prevalence of respiratory complaints, radiological abnormalities, and functional deficit,, leading to sedentary life. Even in the absence of positive laboratory results, the chances of the impact of TB are high. However, some smear-negative recurrent TB may be undiagnosed chronic lung illness. There is still a need for research to understand the pathophysiology of pulmonary TB sequelae. However, it is apparent that such complications induce pulmonary impairment and contribute significantly to the global burden of chronic respiratory disorders. Greater awareness is needed to implement pulmonary rehabilitation for postpulmonary TB impact, leading to improved overall quality of life of patients.
To conclude, although pulmonary TB sequelae are one of the causes of chronic lung disease, very little literature is available about pulmonary rehabilitation in them. Indications for pulmonary rehabilitation for post-TB sequelae are reduced exercise tolerance, quality of life, functional status of the lung, and increased symptoms. More research is needed for evidence-based practice. The management of post-TB sequelae using pulmonary rehabilitation (PR) to improve overall quality of life of the patient, functional status of the lung, exercise tolerance, and psychological support can reduce the sedentary life of patients with post-TB sequelae.
