Abstract
gait is the most basic human movement for movement and physical activity. gait is a way of moving with alternating use of both legs to gain support and advancement. gait in healthy people can be considered a coordinated and efficient activity, while the disease can affect its coordination, speed and adaptability.
The purpose of this study was to investigate the kinematic differences of gait in two models of MS.
Methodology: After preparing the list of members of the MS Society of Mazandaran province and approving the disease model by a specialist physician, 45 patients were enrolled in Relapsing-Remitting (RR) model and 22 in Secondary Progressive (SP) model. 38 of people in terms of age and gender were consistent with patient groups, were selected as the control group. Angular limbs and joints and joint angular velocity (lower trunk) variables assessed in this study who were examined in three dimensions. MATLAB 2018 software was used to calculate the desired variables. One-way ANOVA was used to investigate the significant differences.
The SP group was higher in the sagittal and hip pelvic angles in the frontal section than in the control group, but was not different in the leg and foot segments. The knee and ankle joint angles were lower in the frontal plane of the SP group than in the control group. Comparison of SP group showed that knee and ankle joint angular velocity was lower at horizontal level and angular velocity at frontal ankle joint was higher than control group.
Patients with MS have significant differences in gait parameters compared to healthy subjects. Patients in the SP model show more changes than the RR group. Most of these changes occur in the knee and ankle joint. One of the most immediate side effects of these changes in these patients is sudden falls. Trainers and physiotherapists can reduce these serious complications by focusing on these two joints and by strengthening the surrounding muscles.
