Overview

The aim of this study is to investigate the effects of IMT on respiratory muscle strength, pulmonary function tests, quality of life aerobic capacity, dyspnea, fatigue and physical activity level in scleroderma patients with ILD. The study will include 30 Scleroderma + ILD patients who are under follow-up in Fırat University Rheumatology Department. Patients will be randomly divided into two groups. High intensity intermittent inspiratory muscle training (H-IMT) will be applied to the respiratory muscle training group in addition to the exercise program. Respiratory muscle strength will be assessed by maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP); aerobic capacity will be assessed by exercise test and VO2max. Dyspnea will be assessed with the Modified Medical Research Council Scale; fatigue with the Fatigue Severity Scale; quality of life with the Scleroderma Health Assessment Questionnaire; physical activity level with the International Physical Activity Scale - Short Form

Inspiratory muscle training (IMT) is performed by inspiring against an external load provided by a device. It is easy to implement, low cost and can be easily integrated into rehabilitation programs. Pulmonary rehabilitation and inspiratory muscle training have been applied as an effective method in ILD. However, there are no studies investigating the effects of IMT in individuals with ILD. The aim of this study was to investigate the effects of IMT on respiratory muscle strength, pulmonary function tests, quality of life, aerobic capacity, dyspnea, fatigue and physical activity level in scleroderma patients with ILD. The study will include 30 Scleroderma + ILD patients who are under follow-up in Fırat University Rheumatology Department. Patients will be randomly divided into two groups. High intensity intermittent inspiratory muscle training (H-IMT) will be applied to the respiratory muscle training group in addition to the exercise program. This training will be performed with Power breath (POWERbreathe Classic Light Resistance, PowerBreath, IMT Technologies Ltd, Birmingham, UK) respiratory muscle training device. In the control group, only stretching, strengthening and posture exercises will be applied as a home program. Respiratory muscle strength will be assessed by maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP); aerobic capacity will be assessed by VO2max with exercise test. dyspnea will be assessed using the Modified Medical Research Council Scale; fatigue will be assessed using the Fatigue Severity Scale; quality of life will be assessed using the Scleroderma Health Assessment Questionnaire; physical activity level will be assessed using the International Physical Activity Scale - Short Form.

Interventions

Inspiratory muscle trainingOTHER

The H-IMT will be performed in seven sets of three-minute cycles consisting of two minutes of training followed by one minute of rest in the training workload. Each session will consist of 14 minutes of loading and seven minutes of rest for a total of 21 minutes.

ExerciseOTHER

Stretching exercises for pectoral muscles, neck muscles and back muscles, strengthening exercises for upper extremity and back muscles and posture exercises will be applied.

Outcomes

Primary Outcomes

Respiratory muscle strength

Respiratory muscle strength will be assessed with an intraoral pressure gauge. Maximal Inspiratory Pressure (MIP) and Maximal Expiratory Pressure (MEP) are commonly used non-invasive methods to determine respiratory muscle strength. These are intraoral pressures measured at maximum respiration against a valve that closes the airways. When applying MIP, the patient is asked to perform maximal expiration.

Time frame: up to 8 weeks

Secondary Outcomes

Fatigue

Fatigue will be assessed with the Fatigue Severity Scale (FSS), the Turkish validity and reliability of which was performed by Armutlu et al.
