Abstract

Objective: to estimate the time course of changes in foot biomechanical function as multiple sclerosis (MS) progresses in patients with different degrees of disability compared to a control group.
Patients and methods. To estimate the time course of changes in gait disorders in MS, changes in foot biomechanical function were explored in 30 patients with relapsing-remitting MS. Their neurological status was evaluated using the expanded disability status scale (EDSS); pedographic examination was made applying a plantar pressure distribution system; all the patients were examined twice. During the first examination, the patients were divided into two groups: 1) minimal neurological disorders (EDSS scores of < 3.0) and 2) moderate ones (EDSS scores of ≥3.0). 

Results and discussion. The patients with a mild neurological deficit showed increases in foot load and its lateralization by elevating pressure on the heads of the fourth and fifth metatarsal bones, as evidenced by a significant rise in mean pressure, maximum force, and force-time integral. These changes occurred in the absence of the patients’ complaints of changes in movements.
Pedographic examination revealed the changes indicating an enlarged anterior transverse arch and the lower role of the hallux in body weight transfer in the patients with a moderate neurological deficit despite the fact that there were no further visible negative changes in a motor process or progression in neurological deficit. 

The pedographic examination makes it possible to estimate the degree of gait disorders caused by pyramidal and/or cerebellar lesions and to identify a leading role of this or that functional system in their genesis. Pyramidal dysfunction has impact on the pressurization of the heads of the second and third metatarsal bones. Computed pedography can identify clinically subtle movement changes and estimate the time course of changes in movement disorders in MS patients, including those to evaluate the efficiency of therapy and rehabilitation measures.
