Overview
Brief Summary
The primary aim is to evaluate pulmonary function, respiratory muscle strength, upper and lower extremity exercise capacity, muscle oxygenation, dyspnea, peripheral muscle strength, arterial stiffness, physical activity level and balance in children with pulmonary arterial hypertension and compare with age- and sex-matched healthy controls.
The second aim is to investigate the relationship between upper extremity exercise capacity, arterial stiffness, respiratory and peripheral muscle strength
Detailed Description
Pulmonary arterial hypertension (PAH) is defined as higher than 25 mmHg in mean pulmonary arterial pressure at rest. Pulmonary arterial hypertension is chronic and progressive disease. Symptoms such as dyspnea, fatigue, exercise intolerance, cyanosis and syncope are shown in children with PAH. Most common symptom is dyspnea during exertion. Dyspnea at rest could occur while the severity of disease is progressed. All these symptoms have been associated with decreased cardiac output and mismatch oxygen transport. This study is planned as a cross-sectional study. At least 13 children with PAH and at least 13 age- and sex- matched healthy controls will be included in this study. Individuals' pulmonary function (spirometer), respiratory muscle strength (mouth pressure device), upper extremity exercise capacity (the six minute Peg Board Ring Test), lower extremity exercise capacity (six minute walk test), muscle oxygenation ('Moxy' monitor device), dyspnea (modified Borg Scale), peripheral muscle strength (hand-held dynamometer), arterial stiffness (arteriograph device), physical activity level (multi-sensor activity monitor) and static balance (balance system with computed) will evaluated in children with PAH and healthy controls. All assessments will be completed in two days.

Outcomes
Primary Outcomes
Upper extremity exercise capacity
Time Frame: First day
Six minutes PegBoard and Ring Test (6-PBRT) will be applied to evaluate upper extremity exercise capacity. There are a total of 20 rings and 2 wooden bars at above and 2 wooden bars at below. Patients will be asked to move the each two rings from upper bars to lower bars and than from lower bars to upper bars with hands as fast as. The total number of rings moved during the test will be recorded at the end of test.
Muscle oxygenation
Time Frame: First day
Muscle oxygenation will be evaluated with the Moxy monitor (Moxy, Fortiori Design LLC, Minnesota, USA) as a non-invasive. The device will be attached with soft tape on the participants' skin surface. The device will be placed on the 1/3 lower motor point of the deltoid muscle group of the dominant arm during the the six minutes PegBoard and Ring Test and placed on the 1/3 lower motor point of the quadriceps muscle of dominant leg during the six minutes walk test. At rest and during the test, skeletal muscle oxygenation (StO2) and total hemoglobin (THb) values will be recorded.
