Multiple Sclerosis and Respiratory and Functional Capacity

Comparison of Respiratory, Physical Activity and Functional Capacities of Patients wıth Mild Relapsing Remitting Multiple Sclerosis and Healthy Controls

It is known that respiratory functions, physical activities and functional capacities of Multiple Sclerosis (MS) patients decrease with the progression of the disease. However, there is not enough information about the severity of the effects of these parameters in mild Relapsing-Remitting Multiple Sclerosis (RRMS) patients. Our aim in this study is to compare the respiratory functions, physical activities and functional capacities of mild RRMS patients with healthy controls and to examine the relationship between them.

Study Overview

• Status: Completed
• Conditions: Multiple Sclerosis
• Intervention / Treatment: Other: Expanded Disability Status Scale, pulmonary function test, International Physical Activity Questionnaire - Short Form, 6 minute walk test

Detailed Description

It is known that respiratory functions, physical activities and functional capacities of Multiple Sclerosis (MS) patients decrease with the progression of the disease. However, there is not enough information about the severity of the effects of these parameters in mild Relapsing-Remitting Multiple Sclerosis (RRMS) patients. Our aim in this study is to compare the respiratory functions, physical activities and functional capacities of mild RRMS patients with healthy controls and to examine the relationship between them.

Forty individuals diagnosed with RRMS between the ages of 18-60 and 40 healthy individuals with similar demographic characteristics were included in the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pulmonary Function Tests- FEV1/FVC	Evaluation of FEV1/FVC ratio MicroQuark® computer-based USB spirometer will be used to assess the respiratory function of the participants. The person will be asked to take a few normal breaths followed by as deep a breath as possible and instructed to exhale forcefully and quickly without waiting. The test will be terminated by instructing the participant to take a deep breath after exhaling for at least six seconds.	Baseline
Pulmonary Function Tests- FVC	Evaluation of Forced Vital Capacity (FVC) MicroQuark® computer-based USB spirometer will be used for FVC evaluation. The person will be asked to take a few normal breaths, then take as deep a breath as possible, and then exhale forcefully and quickly without waiting. The test will be terminated by instructing the participant to take a deep breath after exhaling for at least six seconds.	Baseline
Pulmonary Function Tests- FEV1	Evaluation of Forced Expiratory Volume in 1 second (FEV1) MicroQuark® computer-based USB spirometer will be used for FEV1 evaluation. The person will be asked to take a few normal breaths, then take as deep a breath as possible, and then exhale forcefully and quickly without waiting. The test will be terminated by instructing the participant to take a deep breath after exhaling for at least six seconds.	Baseline
Pulmonary Function Tests- PEF	Evaluation of Peak Expiratory Flow (PEF) MicroQuark® computer-based USB spirometer will be used for PEF evaluation. The person will be asked to take a few normal breaths, then take as deep a breath as possible, and then exhale forcefully and quickly without waiting. The test will be terminated by instructing the participant to take a deep breath after exhaling for at least six seconds.	Baseline
Pulmonary Function Tests- MVV	Maximum voluntary ventilation (MVV) MicroQuark® computer-based USB spirometer will be used for MVV evaluation. Then the participant will take the disposable bacteria filter mouthpiece between his lips and holds it tightly. The person will be asked to deeply and rapidly breaths for 10 to 15 seconds.	Baseline
Functional Capacity	The 6-minute walk test (6MWT) was used to measure functional capacity. In the test, the participant was asked to walk for 6 minutes as fast as possible in a 30-meter corridor, and the total distance in meters was recorded. Standard encouragement was given to the participant every 60 seconds during the test. Estimated values of participants For men; (7.57 x height(cm)) - (5.02 x age) - (1.76 x kg) - 309, for women; Calculated with the formula (2.11 x height(cm)) - (2.29 x kg) - (5.78 x age) + 667.	Baseline
International Physical Activity Questionnaire - Short Form	The International Physical Activity Questionnaire-Short Form (IPAQ-SF) was used to evaluate physical activity. It was developed to evaluate the physical activities of people between the ages of 15-60 in their daily lives. It consists of seven questions in total and questions the time spent in vigorous, moderate-to-severe and walking activities. In addition, the sitting time is considered as a separate question. The Metabolic Equivalent (MET-minute) score is determined at the end of the calculation made by multiplying the MET value of the activities performed by the minute. Classification is based on the numerical data obtained. Accordingly, there are 3 activity levels: Inactive, minimal active and very active. The lowest level of physical activity is inactive and the highest level of physical activity is very active. The IPAQ is a valid and reliable test in MS patients.	Baseline

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Expanded Disability Status Scale	The Expanded Disability Status Scale is a method of quantifying disability in multiple sclerosis. The scale is based on a neurological examination by a clinician. It has steps from 0 to 10. The higher scores indicate higher neurological disability.	Baseline
