Abstract

Introduction:

Stroke patients have problems with voluntary movement and trunk control. Moreover, the respiratory function in stroke patients is affected by neurological impairment, which increases the incidence of respiratory complications.

Objectives:

To determine the correlation between trunk rotation range of motion (TRROM) and trunk lateral flexion range of motion (TLFROM), peak cough flow (PCF), and chest expansion in stroke patients.

Methods:

This was an observational study involving 21 patients with a clinical diagnosis of stroke from October 2021 to January 2022. TRROM and TLFROM were assessed using smartphone applications (Compass and Clinometer), respectively, PCF was assessed using a peak flow meter, and chest expansion was assessed using a tape measure. Pearson's correlation was used to analyze the relationships between the variables.

Results:

Statistically significant correlations were found between TRROM and TLFROM (r = 0.91, p < 0.01) and between upper chest expansion and PCF (r = 0.59, p < 0.01). There were significant correlations between lower chest expansion and TRROM (r = 0.50, p < 0.05) and between lower chest expansion and TLFROM (r = 0.51, p < 0.05).

Conclusion:

This study demonstrates the relationship between upper chest expansion and PCF. Upper chest expansion exercises should be considered to improve the PCF in stroke patients. In addition, a very strong positive correlation between TRROM and TLFROM was demonstrated. TRROM and TLFROM exercises should be considered to improve the lower chest expansion in stroke patients.

Respiratory Volumes

Respiratory Volumes

Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.
Tidal Volume (TV) Tidal volume (TV) is the air inhaled or exhaled in a...

Pulmonary Function Tests

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
