This study aims to investigate the effects of functional inspiratory muscle training, basic inspiratory muscle training and physical activity in addition to respiratory exercises on respiratory muscle strength, respiratory function, cognition, walking, balance, functional exercise capacity, physical activity, quality of life and core muscles in volunteer Multiple Sclerosis (MS) patients. This study is planned as a prospective, randomized and experimental study.
Multiple Sclerosis (MS) is an autoimmune disease of the central nervous system and is a chronic and progressive disease characterized by inflammation, demyelination, and axonal degeneration. Due to axonal damage and demyelination, various neurological findings with motor and sensory losses are observed in patients with MS depending on their localization in the central nervous system. These findings vary depending on the location and size of the lesion, frequency, and severity of the disease. It is known that there are 2.8 million people living with MS in the world. Generally, the first symptoms appear between the ages of 20-40, but it is defined as early-onset or pediatric under the age of 18, adult-onset between the ages of 18-49, and late-onset after the age of 50. It is approximately twice as common in women, and is more common between the ages of 20-50, especially in white races. Although four clinical types are defined in MS: relapsing remitting MS, primary progressive MS, secondary progressive MS, relapsing progressive MS, clinically isolated MS has been added to the current classification, and the relapsing progressive MS classification has been abolished and those in this classification have been included in the primary progressive MS class. The relapsing remitting type is the most common, and there are periods of exacerbation (relapse) and remission in this type. Complications that occur during the exacerbation period show full or near-full recovery during the remission period. Various neurological findings such as spasticity, muscle weakness, gait disturbance, cognitive impairment, swallowing problems, bladder-bowel dysfunction can be observed in MS patients, and respiratory complications constitute one of the most common and important causes of death in MS. The risk of death is almost 12 times higher due to respiratory complications, which constitute approximately 47% of the causes of death in MS. Involvement of the pulmonary system, which is usually observed to have deterioration in diffusion capacity, respiratory muscle strength, and ventilation-perfusion ratio, leads to exercise intolerance, hospitalization, and mortality in MS. In MS, the primary factor is the formation of demyelinating plaques in the central nervous system, and the secondary factors include medications used, fatigue due to the disease, increased body temperature, a sedentary lifestyle, and loss of fitness, which all come together to cause pulmonary effects such as respiratory muscle weakness, lung volume deterioration, neurogenic pulmonary edema, sleep-disordered breathing, impaired respiratory control, decreased coughing efficiency, and respiratory failure. When the literature is examined, it seems that there is a need to try new methods in these disease groups to prevent respiratory complications and improve respiration due to pulmonary effects seen in MS. This study aims to investigate the effects of functional inspiratory muscle training, basic inspiratory muscle training, and physical activity applied in addition to respiratory exercises on respiratory muscle strength, respiratory function, cognitive function, walking, balance, functional exercise capacity, physical activity, quality of life, and core muscles in patients with Relapsing Remitting type Multiple Sclerosis.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Functional Inspiratory Muscle Training Group | Experimental | The functional inspiratory muscle training (FIMT) group (n=21) will receive basic inspiratory muscle training (IMT) with a device capable of delivering threshold pressure loading (POWERbreathe) for the first four weeks. The first, middle and last sessions of the week will be supervised (face-to-face) and other sessions will be unsupervised (at home, twice a day, totaling 30 minutes). The intensity of inspiratory muscle training will be adjusted to 50-60% of maximal inspiratory pressure and these measurements will be repeated at the beginning of each week and weekly pressure increases will be adjusted. After the first four weeks are completed, then inspiratory muscle training will be combined with exercises at the beginning of the fifth week, and participants will perform supervised in-person FIMT three days per week for four weeks and unsupervised home IMT on the remaining days. |
|
| Basic Inspiratory Muscle Training Group | Experimental | Basic inspiratory muscle training (IMT) group (n=21) will be given IMT with a device capable of performing threshold pressure loading (POWERbreathe Classic Light Resistance, PowerBreath, IMT Technologies Ltd, Birmingham, UK) for eight weeks. The first day of the week, the middle of the week and the last session will be supervised (face-to-face), and the other sessions will be unsupervised (at home, twice a day, 30 minutes in total). The intensity of inspiratory muscle training will be adjusted to be 50-60% of the maximal inspiratory pressure, and these measurements will be repeated at the beginning of each week and weekly pressure increases will be adjusted. |
|
| Control Group | No Intervention | Participants in the control group (n=21) will be informed about the benefits of at least 150-300 minutes of moderate intensity or 75-150 minutes of vigorous intensity aerobic physical activity and breathing exercises per week and exercise recommendations will be given. Both daily physical activities and breathing exercises will be monitored with a pre-prepared exercise tracking form. Participants will be called to the laboratory for clinical measurements at the beginning and end of the study. Participants in the control group will be taught to do diaphragmatic breathing, thoracic expansion, pursed lip breathing and breath control breathing exercises for 20 minutes a day and will be given as home exercises without supervision, with 1-2 minutes of rest between each exercise. |

|
| Measure | Description | Time Frame |
|---|---|---|
| Inspiratory Respiratory Muscle Strength | Participants' respiratory muscle strength will be measured with a portable device (Micro Medical Micro RPM, UK) that can measure intraoral pressure electronically, which is a non-invasive method, and the results will be recorded as maximal inspiratory pressure (MIP). The participant's nose will be closed with a valve while they are maximally expiratory in a sitting position, and a maximal inspiration will be requested for 1 - 3 seconds to complete the MIP measurement and the measurements will be recorded. The highest of the three best results, with no more than 10% difference between them, among at least five measurements will be recorded as the final data. | 8 weeks |
| Expiratory Respiratory Muscle Strength | Participants' respiratory muscle strength will be measured with a portable device (Micro Medical Micro RPM, UK) that can electronically measure intraoral pressure, which is a non-invasive method, and the results will be recorded as maximal expiratory pressure (MEP). MEP measurement will be completed by closing the nose of the participant who is maximally inspiratory in a sitting position with a valve and asking the participant to exhale maximally for 1-3 seconds, and the measurements will be recorded. The highest of the three best results, with no more than 10% difference between them, among at least five measurements will be recorded as the final data. | 8 weeks |
| Respiratory Function (FEV₁) | Respiratory functions will be assessed with a portable spirometer with the patient in a sitting position according to the criteria set by the American Thoracic Society and the European Respiratory Society. Spirometry measures multiple parameters during a single test. Participants will be asked to take a single forced breath during normal breathing and then exhale a single forced breath, measuring the forced expiratory volume (FEV₁) in the first second of the lung function test. | 8 weeks |
| Respiratory Function (FVC) | Participants will be asked to take a single forced breath during normal breathing and then exhale a single forced breath, measuring the forced vital capacity (FVC) of the lung function test. |

| Basic Inspiratory Muscle Training | Other | The basic inspiratory muscle training group will do muscle training with the POWERbreathe device for eight weeks. |
|
| 8 weeks |
| Respiratory Function (FEV₁/FVC) | Participants will be asked to take a single forced breath during normal breathing and then exhale a single forced breath, measuring the forced expiratory volume in the first second/forced vital capacity ratio (FEV₁/FVC) of the lung function test. | 8 weeks |
| Respiratory Function (PEF) | Participants will be asked to take a single forced breath during normal breathing and then exhale a single forced breath, measuring peak expiratory flow rate (PEF) of the lung function test. | 8 weeks |
| Respiratory Function (FEF%25-75) | Participants will be asked to take a single forced breath during normal breathing and then exhale a single forced breath, measuring forced expiratory midflow rate (FEF%25-75) of the lung function test. | 8 weeks |
| Respiratory Function (VC) | Respiratory function will be assessed with a portable spirometer with the patient in a sitting position according to the criteria determined by the American Thoracic Society and the European Respiratory Society. The test will be repeated three times. Participants will be asked to inhale deeply and exhale deeply for sixty seconds. As a result of three consecutive tests, the highest and percentages of the expected vital capacity (VC) values of respiratory function will be obtained. | 8 weeks |
| Paced Auditory Serial Addition Test (PASAT) | PASAT test is a test used to evaluate attention, processing speed and working memory. Within the scope of the test, participants are required to add numbers given at a certain speed and add each new number to the previous number. | 8 weeks |
| Symbol Digit Modalities Test (SDMT) | This test is a test that measures cognitive processing speed. Patients match the numbers corresponding to certain symbols by finding their equivalents as much as possible. | 8 weeks |
| Stroop Test | The Stroop test will be used to measure executive functions and attention control. Participants are asked to name the ink colors of words written with color names. For example, when the word "green" is written in blue ink, participants should say "blue." | 8 weeks |
| Walking | Participants' walking will be evaluated with a 10-meter walking test. Participants will be positioned at the starting line in a pre-measured 10-meter area and the time will be started when the participant steps on the starting line. If the participant uses a walking aid, they will be allowed to walk with it and the measurement will be made twice. The time will end when the participant crosses the finish line at the end of the 10 meters and the best value will be recorded in m/sec. | 8 weeks |
| Balance | Balance will be evaluated with a timed up and go test. The participant, sitting on the chair, with feet flat on the floor and arms resting on the chair rest, will be asked to get up from the chair, walk the previously measured three-meter area at a safe and normal pace, turn, walk back, and sit back on the chair. The time will be measured in seconds for three repetitions and the best result will be recorded. | 8 weeks |
| Functional Exercise Capacity | The functional exercise capacity of the participants will be measured with a 6-minute walk test. The 6-minute walk test is used to determine the maximum distance the participant can walk in six minutes. It is used to measure walking fatigue and walking endurance. Before starting the test, the participants will be informed that they will have to walk as fast as possible without running in a thirty-meter corridor for six minutes and that they can rest by taking a break if they wish, but their rest periods will not be added to the six minutes. The participants will be encouraged once per minute with standard expressions during walking. The distance the participant has walked at the end of the six minutes will be recorded in meters. | 8 weeks |
| Physical Activity | Participants' physical activity status will be assessed with the International Physical Activity Questionnaire short form (SF-IPAQ). The survey consists of seven questions. The duration and frequency of each activity performed in the last week are questioned in the survey. The MET values defined for walking (3.3 METs), moderate-intensity physical activity (4.0 METs) and vigorous-intensity physical activity (8.0 METs) will be multiplied by duration (minutes) and frequency (days) to reach physical activity score values (MET-min/week). | 8 weeks |
| Quality of Life | The participants' quality of life will be assessed with the Multiple Sclerosis International Quality of Life Questionnaire, a MS-specific assessment scale. The scale consists of nine subgroups; Daily Living Activities, Psychological Status, Findings, Relationships with Friends, Family Relations, Emotional and Sexual Life, Acceptance of the Disease, Coping with the Disease and Relationships with Medical Personnel. Each question in this scale, consisting of a total of 31 questions, is scored between 0-4 as "Never, Never" (0 points), "Rarely, A Little" (1 point), "Sometimes, A Little" (2 points), "Frequently, A Lot" (3 points), "Always, A Lot" (4 points). In the evaluation, the total score is calculated and the actual score is obtained by dividing by 1.24 for linear transformation, since the maximum score that can be obtained from the scale is 124. Low scores indicate high quality of life. | 8 weeks |
| Core Muscles (Pelvic Bridge Test) | The pelvic bridge test and modified plank test will be used to assess the stabilization of the core muscles. For the pelvic bridge test, participants will be asked to lie on their backs with their knees flexed and their arms extended at their sides, and then they will be instructed to straighten their trunk by lifting their pelvic region. The time they can maintain this position will be recorded. | 8 weeks |
| Core Muscles (Modified Plank Test) | The pelvic bridge test and modified plank test will be used to assess the stabilization of the core muscles. In the modified plank test, participants will be shown a series of movements and the time they maintain these positions will be recorded and measured. | 8 weeks |
