Summary

This study aims to determine the early effectiveness of combined high-intensity interval inspiratory and expiratory muscle training in hospitalized patients with acute stroke. Participants will be assigned to receive either combined high-intensity interval inspiratory and expiratory muscle training or conventional diaphragmatic breathing exercises.

The main questions this study aims to answer are whether the combined high-intensity interval inspiratory and expiratory muscle training can improve:

* inspiratory muscle strength, measured using maximal inspiratory pressure;
* expiratory muscle strength, measured using maximal expiratory pressure;
* chest expansion, measured using thoracic expansion; and
* the ability to sustain speech on a single breath, measured using the single-breath count test.

Researchers will compare changes before and after the intervention between the two groups to determine whether combined high-intensity interval inspiratory and expiratory muscle training provides greater early improvement than conventional diaphragmatic breathing exercises in hospitalized patients with acute stroke.

Interventions

BEHAVIORAL

High-Intensity Interval Inspiratory and Expiratory Muscle Training (H-IIIEMT)

High-intensity interval inspiratory and expiratory muscle training is performed using the BigBreathe Double Action IMT/PEP device, which provides resistance during inspiration and expiration. Participants perform the exercise in a semi-Fowler position using a mouthpiece with an airtight lip seal. Training is performed once daily for 5 consecutive days, with five 2-minute sets per session and approximately 1 minute of rest between sets. Inspiratory resistance is set at 50% of MIP and expiratory resistance at 30% of MEP.

BEHAVIORAL

Control Group

Diaphragmatic Breathing Exercise for 15 minutes in a semi-Fowler position.
