Abstract
The theoretical change is in harmony with the health of the biological system. The variability and fluctuations in gait have been hypothesized to indicate impaired motor control.

The purpose of this study was to compare the coordination and variability of joints and lower limbs in active and inactive groups with multiple sclerosis (MS) during a gait task.

In this cross-sectional and post-event study, 72 patients with multiple sclerosis (MS) and 38 healthy controls voluntarily participated in four groups of active control (n = 18), inactive control (n = 20), Active MS (n = 27) and inactive MS (n = 45) were divided. Coordination and change internal and external rotation leg / Inversion Eversion Foot (IERL/IEF), Internal and external rotation between thigh and leg (IERThL), Internal and external rotation of the knee and ankle joint (IERKNJ) and internal and external rotation of the knee and thigh joint (IERKThJ), Calculated in MATLAB software. One-way ANOVA was used. Each variable was calculated at 5, 20, 35, 50 and 100% of a step.

The results of one-way ANOVA showed that there was a significant difference between groups in coordination IERL / IEF in phase 5, IERThL in phase 5 and 50, IERKNJ in phase 20, 35, 50. Variability IERL / IEF in Phase 5 and Phase 35 and IERThL phase 5, 35, 50, 100 there is a significant difference between the groups. Patients with physical activity were close to the passive group (inactive control) and had a better condition than the inactive MS group.
The difference in gait variability and coordination of MS patients is probably related to muscle quality, decreased degrees of freedom, and increased neuronal noise. Doing physical activity in MS patients can keep them at the level of healthy people without a history of exercise.
