It is stated that 85% of patients with Multiple Sclerosis (MS) complain of gait disorders and 35-90% of them have fatigue. Many factors play a role in the fatigue mechanism in MS patients. Fatigue can increase the symptoms that already exist in MS patients. It is thought that fatigue caused a decrease in muscle strength, making walking worse. There are not enough studies investigating whether fatigue affects gait parameters in MS patients.
The aim of this study is to examine the effects of muscle fatigue on muscle strength, joint position sensation, and gait in MS patients.
Patients with MS between 0-5,5 score according to the Extended Disability Status Scale (EDSS) and healthy individuals of similar age and sex to patients will be included in the study. The muscle strength, joint position sensation, gait, and fatigue will be evaluated once.
The investigators will use descriptive statistics and t-tests to compare demographic characteristics between groups and for the categorical variables chi-square. Effect of the group (MS patients or healthy controls), condition (Single task and dual-task conditions), and group × condition interaction will be compared using two-way repeated-measures ANOVA.
3,460 studies on the registry are indexed under Multiple Sclerosis; 661 are open to participants now.
This study's enrollment of 36 is below the median of 100 across 1,016 observational studies indexed under Multiple Sclerosis.

ambulatory sample
Exclusion Criteria:
MS patients (EDSS: 0-5,5)
Other: Muscles Fatigue
Healthy individuals without chronic disease
Other: Muscles Fatigue
An exhaustion protocol that reduces knee joint flexor and extensor torque will be applied.
Knee proprioception
Knee proprioception will be evaluated with the active joint reposition test using the isokinetic system (Cybex Norm, Humac, CA, USA).
Time frame: 10 minutes
Knee strength
Knee strength will be evaluated using the isokinetic system (Cybex Norm, Humac, CA, USA).
Time frame: 20 minutes
Gait
Gait parameters will be assessed via the G-Walk on two separate occasions. The G-Walk is a device that is worn on the waist via an elastic belt. The G-Walk is built with a triaxial accelerometer 16 bit/axes with multiple sensitivity, a triaxial magnetometer 13 bit and a triaxial gyroscope 16 bit/axes with multiple sensitivity. This hardware is capable of acquiring and transmitting data to a computer through a Bluetooth connection and at the end of each analysis an automatic report containing the gait assessment results is ready to be analyzed. Gait symmetry values of the right and left sides are obtained within this report. While the symmetry index ranges from 0 to 100, a value closer to 100 indicates that the gait is more symmetrica.
Time frame: 5 minutes
Perceived Exertion
The Borg Rating of Perceived Exertion (RPE) scale is a tool for measuring an individual's effort and exertion, breathlessness, and fatigue.
Time frame: 1 minute
