Multiple Sclerosis l: Introduction01:19

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Summary

Multiple sclerosis (MS) patients with gait disorders tend to increase foot contact area to maintain balance. They also exhibit foot abduction and pronation, altering plantar pressure distribution.

Area of Science:

  • Biomechanics
  • Neurology
  • Human Locomotion

Background:

  • Multiple sclerosis (MS) is characterized by diverse gait patterns due to its impact on the nervous system.
  • Understanding these gait abnormalities requires complex biomechanical analysis.

Purpose of the Study:

  • To investigate specific biomechanical gait patterns in multiple sclerosis patients.
  • To analyze plantar pressure distribution and foot orientation during gait in MS patients.

Main Methods:

  • Biomechanical evaluation of 13 MS patients with gait disorders using a plantar pressure platform (Footscan Scientific Version, RSscan).
  • Analysis of parameters including contact area, heel rotation, foot balance, and foot angle.
  • Evaluation of heel, medial foot, and forefoot zones during the gait cycle.

Main Results:

  • MS patients showed a tendency to increase overall foot contact area to compensate for balance deficits.
  • Significant differences in maximum and minimum contact area values were observed between feet.
  • Foot deviation in abduction and pronation was noted, associated with decreased medial plantar contact area.

Conclusions:

  • MS-related gait disorders involve compensatory strategies like increased foot contact area.
  • Abnormal foot positioning (abduction, pronation) affects plantar pressure distribution in MS patients.
  • Biomechanical analysis provides insights into the complex motor patterns in multiple sclerosis.
