Short Term Effects of Early Respiratory Muscle Training on Respiratory Muscle Strength in Inpatient Acute Stroke
Sponsor: Prof. R. D. Kandou General Hospital
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.

Conditions
Interventions
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.
Control Group
Diaphragmatic Breathing Exercise for 15 minutes in a semi-Fowler position.
