Effect Of Breather On Pulmonary And Physical Function In Post Stroke Survivors

Not Applicable

Completed

• Conditions: Stroke
• Interventions: Device: BREATHER; Other: physiotherapy prgramme for rehabilitation of stroke patients

• Registration Number: NCT05678816
• Lead Sponsor: Cairo University

Brief Summary

Stroke is the second major cause of death and disability worldwide with over 13 million new cases annually.

Egypt, a low-middle-income country, is the most populated nation in the Middle East with a high overall crude prevalence rate of stroke (963/100,000 inhabitants), accounting for 6.4% of all deaths and the incidence of stroke annually is approximately 150,000-210,000.

Stroke has a direct impact on health systems, resulting in high costs, and is also considered a global public health problem due to serious disabilities, functional limitations and compromised quality of life (QoL).

The Breather a drug-free, evidence-based inspiratory/expiratory respiratory muscle training (RMT) device used by Dysphagia, COPD, CHF, Parkinson's, and neuromuscular disease patients, as well as children 4+ and adults interested in healthy aging.

Detailed Description

Stroke is a leading cause of death and disability in globally and particularly in low and middle-income countries, and this burden is increasing.

The expected spontaneous biological recovery follows the "proportional recovery rule" - most patients recover 70% of their impaired motor or verbal function during the first three months after stroke however, 90% of them have residual deficit.

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, dyspnea and increased sedentary behaviour, as well as an elevated risk of recurrent stroke. The reduction in respiratory function may also cause aspiration, leading to pneumonia. Previous research showed that pneumonia was an independent risk factor for mortality and a poor prognosis in stroke patients. Research also showed that a reduction in respiratory muscle and abdominal muscle strength contributed to pulmonary and respiratory dysfunction following a stroke.

After a stroke, the respiratory center and related motor pathways can directly decrease respiratory muscle strength and subsequently induce a change in breathing patterns. As a result, pneumonia, pulmonary ventilation disorders, lung injury, lung ischemia reperfusion injury, decreased pulmonary compliance, abnormal posture, and obstructive sleep apnea can occur following a stroke. Thus, pulmonary rehabilitation is critical to reducing these complications. The main forms of pulmonary rehabilitation include exercise training, respiratory muscle training, oxygen therapy, noninvasive ventilation, nutrition support, social psychological support, and health education.

The inspiratory muscles can be specifically trained, with improvement of both muscle strength and endurance by using the breather device.

As result utilizing the breather may help stroke patients recover quickly and avoid respiratory complication.

Primary Outcome Measures

Name	Time	Method
peak expiratory flow PEF in litres per second	6 weeks	fifty patients will be assessed for their PEF using spirometer
foced vital capacity FVC in litres	6 weeks	fifty patients will be assessed for their FVC using spirometer
forced expiratory volium in first second FEV1 in litres	6 weeks	fifty patients will be assessed for their FEV1 using spirometer
peak inspiratory flow PIF in litres per second	6 weeks	fifty patients will be assessed for their PIF using spirometer

Secondary Outcome Measures

Name	Time	Method
six minute walk distance in metersused to assess functional capacity of patients	6 weeks	the distance walked within six minute will be calculated for every patient
Chest expansion in centimeters using tape measurement	6 weeks	sixty patient willl be assessed for thier chest expansion tape measurement will be used to assess difference in circumference of chest between full expiration and full inspiration.
oxygen saturation in percentage using spirometer	6 weeks	spirometer will be used to indirectly measure saturation of blood by oxygen.
stroke impact scale to assess the effect of stroke on different domains astanderdized score ranging from 0 to 100 is calculated for all domains with higher score indicating a higher quality of life	6 weeks	The stroke impact scale was developed from the perspectives of both patients and care givers. The current stroke impact scale 3.0 is a revised version of the original SIS , with established reliability and validity. The SIS 3.0 contains 59 items measuring eight domains, including strength, hand function, activity of daily living, mobility, communication, emotion, memory/thinking, and participation, with a single item assessing perceived overall recovery from stroke
