NCT ID: NCT06410638 Recruiting - Muscle Oxygenation Clinical Trials

Intercostal Muscle Oxygenation During Exercise Tests

Start date: May 10, 2024
Phase:
Study type: Observational

The aim of our study is to determine the effects of different exercise capacity tests on intercostal muscle oxygenation and to reveal the effect of changing accessory respiratory muscle oxygenation on exercise test success.

NCT ID: NCT06294223 Recruiting - Clinical trials for Near-infrared Spectroscopy

Upper Extremity and Muscle Oxygenation

Start date: March 1, 2024
Phase: N/A
Study type: Interventional

The aim of this study was to measure the acute change in oxygen saturation of skeletal muscle during resistance exercise in the upper extremity using near-infrared spectroscopy.

NCT ID: NCT06041126 Recruiting - Clinical trials for Chronic Obstructive Pulmonary Disease

The Effect of Clinical Parameters on Muscle Oxygenation in Patients With COPD

Start date: April 24, 2023
Phase:
Study type: Observational

The aim of this study is to examine the peripheral muscle oxygenation of patients with Chronic Obstructive Pulmonary Disease at rest, during submaximal exercise and recovery, and to examine the effects of disease severity and respiratory functions on peripheral muscle oxygenations. In this study, the effect of disease severity and respiratory problems on peripheral muscle metabolism of patients with COPD will be explained.

NCT ID: NCT05808621 Recruiting - Clinical trials for Chronic Obstructive Pulmonary Disease

Muscle Oxygenation in Chronic Obstructive Pulmonary Disease

Start date: March 8, 2023
Phase:
Study type: Observational

The aim of our study is to examine the Peripheral Muscle Oxygenations at rest and in motion on the 2nd day of hospitalized patients and before discharge in Severe Acute Exacerbation of Chronic Obstructive Pulmonary Disease and to compare the results in the hospital periods by repeating the tests in the stable periods of the patients 1 month after discharge.

NCT ID: NCT05655559 Not yet recruiting - Muscle Oxygenation Clinical Trials

Muscle Oxygenation in Treadmill and Cycle Ergometer Exercise

Start date: December 30, 2022
Phase: N/A
Study type: Interventional

The study will be conducted on healthy young adults. Hemodynamic effects such as heart rate, blood pressure, oxygen saturation (SpO2), including muscle oxygenation, will be compared in treadmill and bicycle exercises.

NCT ID: NCT05011565 Completed - Clinical trials for Hemodynamic Instability

Hemodynamic, Vascular and Muscular Parameters of Exercise Capacity in Single-Ventricle Patients With Fontan Procedure

Start date: January 20, 2021
Phase:
Study type: Observational

After the Fontan procedure applied in patients with a functional or anatomical single ventricle, patients are faced with significant morbidity and mortality risk. Most of the common complications after Fontan such as arrhythmia, cyanosis, ventricular dysfunction, heart failure, atrioventricular valve insufficiency, protein-losing enteropathy, thrombosis, bleeding, venous insufficiency directly or indirectly limit exercise capacity. It has been reported that hemodynamic, vascular and muscular factors may be effective in the decrease of exercise capacity. In previous studies, it has been reported that cardiac output, one of the hemodynamic parameters, is the main factor affecting exercise capacity in patients with Fontan, and this is due to insufficient increase in stroke volume. In addition to the hemodynamic profile, the effects of muscle oxygenation, arterial stiffness and peripheral muscle strength on exercise capacity have been mentioned in different studies. For this reason, it is thought that examining the effects of hemodynamic, vascular and muscular profile together on submaximal and maximal exercise capacity in patients with Fontan will provide information about the mechanisms of influence of different exercise capacities and will provide important information in terms of determining exercise-based rehabilitation programs for such patients.

NCT ID: NCT00747162 Withdrawn - Skin Pigmentation Clinical Trials

Muscle Oxygenation and Skin Pigmentation

Start date: August 2008
Phase: Phase 4
Study type: Interventional

The investigators plan to enroll 500 consecutive Subjects at a major trauma center for this study. For each patient, the body mass index (BMI), age, sex, diastolic pressure and mean arterial pressure (MAP) at time of measurements. Additional information including diseases such as diabetes and vascular disorders will be recorded. Social demographics including alcohol and tobacco use will be recorded. This is important as alcohol and tobacco use could also contribute to cardiovascular diseases. The skin pigmentation of each subject will be recorded. Two different methods will be used for this measurement. Each patient will be graded on a six point scale as described by Young (Young, 1997). Additionally, each subject will have their skin measured using a reflectance colorimeter. The colorimeter, DermaSpectrometer II (cyberDerm, Broomall, PA) uses visible light to measure the amount of light reflected off the skin. By measuring the light reflectance, the skin pigmentation can be measure (Clarys, 2000). Muscle oxygenation will be measured using a continuous dual wavelength near infrared spectrometer. Using the different absorption characteristics of deoxyhemoglobin and oxyhemoglobin, the concentration of oxyhemoglobin in the muscle at an approximate depth of 2.5 cm is determined. The INVOS cerebral oximeter (Somanetics, Troy, MI) will be used for all measurements.
