Brief Summary:
This study evaluates the predictors of intensive care unit admission and mortality among stroke patients and the effects of pulmonary physiotherapy on these stroke patients. One-hundred patients participated in the pulmonary rehabilitation program and 81 patients served as a control group.

Stroke, Ischemic Intensive Care Neurological Disorder Morality Rehabilitation Other: Pulmonary physiotherapy

Detailed Description:

Predicting early mortality and disability after a stroke depends on many factors, such as age, the type of stroke, lesional location, level of consciousness, severity of neurological impairment, medical risk factors (hypertension and diabetes), premorbid conditions, fever and history of stroke. Stroke patients may experience a reduction of up to 50% in respiratory function when compared to age- and gender-matched norms. The reduction in respiratory function can lead to decreased endurance, dyspnoea and increased sedentary behaviour, as well as an elevated risk of stroke. The reduction in respiratory function may also cause aspiration, leading to pneumonia.

The aim of pulmonary rehabilitation program is to enhance respiratory muscle resistance during breathing, thereby improving respiratory function. Pulmonary rehabilitation programs are considered to be capable of inducing positive effects on stroke patients' respiratory muscles through diaphragm breathing exercise and lip puckering breathing exercise. Pulmonary physiotherapy (PPT) improves the quality of life of stroke patients.

The PPT program was conducted by physical therapists at our hospital for 30 min, three days/week. As part of the PPT, a physiotherapist monitored this group for 12 weeks. The same physiotherapist supervised all the exercises. During the exercise program, all patients were clinically stable and all were receiving optimal medical therapy. Rehabilitation started with inspiratory diaphragm breathing exercises. The physiotherapist placed his hands on the superior rectus abdominis immediately below the anterior costal cartilage and induced inspiratory diaphragm breathing by instructing the patient to slowly and deeply inhale the air through the nose. Then the patient was instructed to perform expiratory pursed-lip breathing exercise by continuously exhale the air. During pursed-lip breathing exercise, the patient was instructed in sequence, to breathe in gently through the nose, purse his/ her lips as though whistling and then breathe out through the long pursed lips by not exerting power until she/ he is short of breath. The expiration time was set to be at least twice times longer than inspiration time. The patients took a rest when they complained about fatigue or dizziness during breathing exercise and conducted breathing exercise again. The exercise intensity was based on the maximal heart rate and maximal effort of the patients. Each patient's performance during the exercise sessions was recorded and reported regularly to the patient's physician. National Institute of Health Stroke Scale scores, modified Rankin scale scores, pneumonia onset, admission to the intensive care unit and mortality were recorded at the end of the first and third month.
