Introduction: Multiple Sclerosis (MS) is a disease with wide symptoms variation and gait disturbances are amongst the most impactful. It is crucial to identify early gait deviations. The objective of this study is to describe and analyze biomechanical characteristics of gait deviations in subjects with minimally impaired MS (less then 4.0 in Expanded Disability Status Scale-EDSS).
Material and methods: Thirteen subjects with minimally impaired MS (4 man and 9 women) participated in this cross-sectional study. Vicon system®, AMTI OR6-6 force plates, Delsys Trigno electromyography and descriptive statistics were used.
Results: Age range was 18 to 59 years (35,3±11,1y) and time since diagnosis 15 days to 22 years. When compared to normal data (p< 0,05), All subjects showed some gait disturbance. Only one has not shown temporospacial alteration. 46% of the subjects had 7 to 30% decrease on gait speed. On kinematics, 61,5% of the subjects had decreased Gait Deviation Index (GDI), 100% showed abnormal ankle kinematics as decreased foot progression angle and low plantar flexion (both 62%). 70% showed some pelvic abnormality been increased pelvic tilt the most common (46%). Hip abnormality was seen in 92% of the subjects. The most commom were excessive adduction (62%) followed by lack of extension (46%). Knee problems were present in 84% of the subjects and the most frequent was reduced swing knee flexion (46%) and hyperextension (38%). Kinetic abnormalities were found in 92% of the subjects. Reduced anterior-posterior ground reaction force positive and negative peaks (38%), increased hip (30%) and knee (38%) flexor moment, increased hip power generation (38%) and reduced knee power generation (30%) were the most frequent ones.
Discussion and conclusions: These results suggest that even in minimally impaired EM subjects temporospatial, kinematic and kinetic gait disturbances can be found.
