Short Term Effects of Early Respiratory Muscle Training on Respiratory Muscle Strength in Inpatient Acute Stroke
Short-Term Effects of Early Combined High-Intensity Interval Inspiratory and Expiratory Muscle Training on Respiratory Muscle Strength in Inpatients With Acute Stroke
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.

|---|---|
|
Expérimental: Intervention Group
High-Intensity Interval Inspiratory and Expiratory Muscle Training
|
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.

Comparateur actif: Control Group
Conventional Diaphragmatic Breathing Exercise
|
Diaphragmatic Breathing Exercise for 15 minutes in a semi-Fowler position.

Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Maximal Inspiratory Pressure
Délai: Baseline and Day 3
|
Maximal inspiratory pressure (MIP) is used to assess inspiratory muscle strength.
Participants perform a maximal inspiratory effort against an occluded airway starting from residual volume.
MIP is recorded in centimeters of water (cmH₂O).
A greater magnitude of MIP indicates greater inspiratory muscle strength.
|
Baseline and Day 3
|
|
Maximal Expiratory Pressure
Délai: Baseline and Day 3
|
Maximal expiratory pressure (MEP) is used to assess expiratory muscle strength.
Participants perform a maximal expiratory effort against an occluded airway.
MEP is recorded in centimeters of water (cmH₂O).
Higher MEP values indicate greater expiratory muscle strength.

Description de la mesure |
Délai |
|---|---|---|
|
Thoracic Expansion
Délai: Baseline and Day 3
|
Thoracic expansion is assessed as the difference in chest circumference between maximal inhalation and maximal exhalation.
Chest circumference is measured using a measuring tape at a standardized thoracic level and is reported in centimeters (cm).
A greater difference indicates greater chest wall expansion.
|
Baseline and Day 3
|
|
Single-Breath Counting Test (SBCT) Score
Délai: Baseline and Day 3
|
The Single-Breath Counting Test (SBCT) is a bedside assessment of respiratory function.
After a maximal inspiration, participants count aloud sequentially for as long as possible during a single exhalation.
The highest number reached during one breath is recorded as the SBCT score.
A higher score indicates a greater ability to sustain phonation during a single breath.
