Brief summary

This study aims to determine the possible effects of inspiratory muscle training on cardiovascular, respiratory, physical and psychosocial functions in patients with PH.

Detailed description

Pulmonary Hypertension (PH) is a hemodynamic finding related to increase in pulmonary artery pressure. Because PH disease is a progressive, rare disease, it is important for this disease group to prolong the life span and to increase the quality of life and functional capacity. PH patients have been shown to have weakness in peripheral and respiratory muscles. Patients will be randomly assigned to the inspiratory muscle training and control group. Inspiratory muscle training will be initiated in accordance with the patient at a range of 40-60%. İnspiratory muscle training will be given based on the assessments by the physiotherapist. Patients with PH who come to the routine outpatient clinic and volunteer will be included in the study. The first session will be the evaluation session and the 8-week inspiratory muscle training will be given, the other group will be the control group only. Dyspnoea, diaphragm thickness, pulmonary function, respiratory and peripheral muscle strength, blood pressure, arterial stiffness, physical activity, anxiety, depression and quality of life assessments will be repeated before and after the treatment.

Design outcomes

Primary

MeasureTime frameDescription
6 minute walk testChange from Baseline at 8 weeksfunctional capacity

Secondary

MeasureTime frameDescription
Mouth pressuresChange from Baseline at 8 weeksMaximal inspiratory pressure, maximal expiratory pressure and endurance will be measure with mouth pressure device
Modified Medical Research Council Dyspnea ScaleChange from Baseline at 8 weeksModified Medical Research Council Dyspnea Scale is used to measure dyspnea. Higher scores indicate higher dyspnea.
Forced vital capacityChange from Baseline at 8 weeksForced vital capacity is defined as the amount of air that can be forcibly exhaled from the lungs after taking the deepest breath possible.
Forced expiratory volume in 1 secondChange from Baseline at 8 weeksThe volume of air expired in the first second of expiration or forced expiratory volume in 1 second, especially when expressed as a ratio with the total amount of air expired during the forced vital capacity, is a good index of expiratory airways resistance.
Diaphragma thicknessChange from Baseline at 8 weeksDiaphragma thickness will be measured by two dimensional ultrasonography
Levels of blood pressureChange from Baseline at 8 weeksAmbulatory blood pressure monitoring will be used for blood pressure measurement
Nottingham Health ProfileChange from Baseline at 8 weeksHealth-related quality of life will be assessed using Nottingham Health Profile scale which is a general quality of life questionnaire that measures perceived health problems and their impact on normal daily activities. It has 38 items divided into six domains: energy level, pain, emotional reactions, sleep, social isolation and physical abilities. Items use yes/no answer format and each item is weighted. Total scores for each domain range from 0 to 100. Higher scores represent less quality of life in relevant domain.
Isometric muscle strengthChange from Baseline at 8 weeksIsometric muscle strength for knee extensors and shoulder flexors and abductors
Upper extremity exercise capacityChange from Baseline at 8 weeksUpper extremity exercise capacity will be measured with Six-Minute Pegboard and Ring Test. In this test 4 iron rods, and a total of 20 rings are placed on a pegboard. At the end of six minutes, total number of rings placed will count.
International Physical Activity Questionnaire-Short FormChange from Baseline at 8 weeksThe International Physical Activity Questionnaire-Short Form has 7 items listing activities and requests estimates of durations and frequencies for each activity engaged in over the past week. Durations are multiplied by known metabolic equivalents per activity and the results for all items are summed for the overall physical activity score. Scores for walking and for moderate and vigorous activities are sums of corresponding item scores. Higher scores indicate higher physical activity level.
Fatigue Impact ScaleChange from Baseline at 8 weeksThe Fatigue Impact Scale is widely used to measure fatigue. It is a 40-item multidimensional scale measuring the physical, cognitive and social. Patients are asked to rate how much of a problem fatigue has caused them during the past month, including the day of testing, on a 5-point Likert-type scale, with response options ranging from 0 no problem to 4 extreme problem. Loer scores indicate the better results
Changes in Anxiety and DepressionChange from Baseline at 8 weeksAnxiety and depression levels will be assessed by Hospital Anxiety and Depression Scale. The scale consists of 14 items, seven items for the anxiety subscale and seven for the depression subscale. Each item is scored on a response-scale with four alternatives ranging between 0 and 3. Higher scores indicate
Changes in DyspneaChange from Baseline at 8 weeksDyspnea level will be questioned with the modified Borg Scale. Minimum value is 0 (no dyspnea), and maximum value is 10 (maximal dyspnea) Higher scores indicate higher fatigue levels.
Arterial stiffnessChange from Baseline at 8 weeksDuring blood pressure measurements, augmentation index will be measured by non-invasive oscillations over the brachial artery.
