Rehabilitation programs for patients with pulmonary disease have existed for more than 25 years.
The American Thoracic Society position paper and most of the research have shown the benefits of rehabilitation for patients with COPD.
The need for early detection and treatment of respiratory dysfunction is widely accepted.

Rehabilitation research is beginning to emphasize functional outcomes such as improvement in lung function, heart function, to improve maximal aerobic capacity and decrease mortality rate.
It is concerned with the issues of disability.

Pulmonary Rehabilitation as defined by National Institute of Health(1994) is “A multi-disciplinary continuum of services directed to persons with pulmonary disease and their families, usually by an interdisciplinary team of specialists, with the goal of achieving and maintaining the individual’s maximum level of independence and functioning in the community”
Physiotherapists play an integral part in management by giving the techniques aimed to reduce the work of breathing and improving disability.

It is an holistic approach to treatment of patients and their families with respiratory disease and requires number of health professionals such as:
The Advisory Board The Medical Director The Program Director The Respiratory Care Specialist The Exercise Specialist The nutritionist or Dietitian The Behavior Specialist

The main symptom is dyspnoea which is associated with anxiety and fear.
Limitations during daily life and reductions in exercise tolerance
Leg fatigue at lower work intensities compared to normals.

Assessment of patient should be done and than followed by problem list, goals should be made for proper pulmonary rehabilitation.
It includes: 1. history (history of presenting illness, previous
medical history, drug history, family history, social history)
2.subjective assessment

3.Objective assessment - general observation like patient’s position, any
drips, drains, oxygen supply etc-observation of chest shape, breathing pattern, chest
movement-palpation of trachea position, chest expansion-percussion-auscultation(breath sounds, any abnormal sounds,
heart sounds)-exercise capacity of patient-examination of heart rate, blood pressure,
respiratory rate,spirometry4.Test results-ABG analysis, chest radiographs

Components of pulmonary rehabilitation
![Page 20: Pulmonary rehabilitation](https://reader038.vdocuments.us/reader038/viewer/2022110119/555dd014d8b42aec698b52e3/html5/thumbnails/20.jpg)
General care -As soon as patient comes, evaluation should be
done for medical and physical diagnosis-Prescription of medicine and oxygen support-Preventive care(smoking cessation, adequate
hydration, proper nutrition etc)
Pulmonary care -respiratory treatment techniques for clearing
accumulated pulmonary secretions include: -bronchial drainage-breathing techniques
![Page 21: Pulmonary rehabilitation](https://reader038.vdocuments.us/reader038/viewer/2022110119/555dd014d8b42aec698b52e3/html5/thumbnails/21.jpg)
-cough facilitation-postures to improve breathing-relaxation techniques-respiratory assistance devices to rest the
breathing muscles at night or during exercise
Exercise and functional testing-instructions for energy conservation, activity
pacing and use of adaptive equipment to optimize the patient ability for daily activities
Education-to provide knowledge and instruction to their
family members and patient regarding disease, its effect, treatment etc
![Page 22: Pulmonary rehabilitation](https://reader038.vdocuments.us/reader038/viewer/2022110119/555dd014d8b42aec698b52e3/html5/thumbnails/22.jpg)
Psychosocial management-its important as chronic disease places stress
on family members as well as for patient-so to provide them with coping strategies,
stress reduction, management techniques, behavioral strategies, and financial assistance as possible
Physical therapy management-physical therapy not only conduct exercise
sessions, they can also provide education regarding educational sessions, smoking cessation programs, weight control and stress management and relaxation techniques.

It depends whether exercises are to be prescribed for strength and endurance and than see the muscle response.
It is based on three components : 1)frequency of training 2)duration of training 3)Intensity of training 4)Mode of exercise
Exercise prescription

Physiological response to training Improved mechanical efficiency
Improvement in mechanical efficiency can improve stride length and gait coordination.
Cardiovascular
Reduction in heart rate, minute ventilation ,lowering of onset of lactic acidosis, lowering maximum oxygen uptake.
Muscle changes
With endurance training , submaximal sustained effort result in transformation from type IIb to type IIa fibres, increasing their oxidative capacity.
With strength training, increase in size of muscle cells and number of myofibrils. So to improve oxygen uptake and ability to maintain aerobic muscle metabolism for prolonged period.
![Page 26: Pulmonary rehabilitation](https://reader038.vdocuments.us/reader038/viewer/2022110119/555dd014d8b42aec698b52e3/html5/thumbnails/26.jpg)
To measure exercise tolerance, laboratory test and field test can be used.
It is needed to set intensity ,assess the benefit of rehabilitation program, motivate the patient with exercise
Laboratory test measuring maximal oxygen consumption, heart rate, workload, arterial oxygenation, blood lactate levels
Field test like 12 min walking test and shuttle walking test are used.

Pulmonary careIndications:
1) removal of excessive secretions that lead to: -obstruction of airways -ventillatory defects -produce symptoms of cough -increase respiratory
infections -deterioration of lung function 2)when secretions are copious ,patients
are chronic

-following treatment can be given based on patients evaluation
Modified bronchial drainage position. foams or cushions can be used to assume trendelenburg position.
For percussion and vibration if adequate assistance is not there, palm cups, mechanical percussors, high frequency chest compression system
Series of deep breathing exercise, forced expirations(huffing), coughing, ACBT, autogenic drainage use of mask providing positive expiratory pressure.
Sustained exerciseDiaphragmatic breathing, pursed lip breathing
can be given to improve lung function.

FlexibilityDue to COPD, there is significant changes in
posture and reduced mobilityIndicationsExercisesPurpose
Respiratory muscle exercise Exercise for improving respiratory muscle
function are important component of pulmonary rehabilitation.
The increased work of breathing and chest wall changes with COPD make respiratory muscle fatigue

Progressive Resistance Exercise in Physical Therapy: A Summary of Systematic Reviews
Nicholas F Taylor, Karen J Dodd and Diane L Damiano
PHYS THER. 2005; 85:1208-1223Result showed that PRE was shown to
improve the ability to generate force, with moderate to large effect sizes that may carry over into an improved ability to perform daily activities

Impact of inspiratory muscle training in patients with COPD: what is the evidence?
(R. Gosselink, J. De Vos, S.P. van den Heuvel, J. Segers,M. Decramer,G. Kwakkel)
A meta-analysis including 32 randomised controlled trials on the effects of inspiratory muscle training (IMT) in chronic obstructive pulmonary disease (COPD) patients was performed.
IMT improves inspiratory muscle strength and endurance, functional exercise capacity,dyspnoea and quality of life. Inspiratory muscle endurance training was shown to be less
effective than respiratory muscle strength training. In patients with inspiratory muscle weakness the addition of IMT to a general exercise training program improved PI,max and tended to improve exercise performance.
