When looking for answers and options to treat patients who are experiencing the above complications, it is important to take a look at exactly how they are interrelated as well as how they differ in stroke patients versus other individuals. As a result, the study that we’re going to discuss in this post compares respiratory muscle strength in stroke survivors and healthy individuals, and investigates the correlation between respiratory muscle strength and exercise tolerance.
- Physical consequence of stroke often include hemiplegia and respiratory muscle weakness, limiting exercise capacity and contributing to poor outcome.
- Respiratory muscle strength was found to be reduced by 60% in stroke survivors.
- Maximal inspiratory pressure (MIP) positively correlated with exercise capacity.
Based in a positive correlation, MIP can directly influence exercise capacity after stroke and improve outcome and survival.
The study examined the following throughout its duration:
MIP and MEP in stroke survivors were reduced by about 60% when compared to the healthy control group. A positive correlation between MIP and 6MWT was found by the Pearson coefficient.
In conclusion, stroke survivors with reduced mobility have significantly reduced respiratory muscle strength. A positive correlation exists between MIP and 6MWT, indicating that respiratory muscle training (RMT) can directly influence exercise tolerance in stroke survivors and contribute to better prognosis and survival. It is, therefore, an important technique and option to keep in mind for patients.
