Ankle Joint01:10

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Summary
This summary is machine-generated.

Rheumatoid arthritis patients exhibit reduced joint motion, moments, and work during walking compared to healthy individuals. Functional disability showed only fair associations with these gait changes.

Area of Science:

  • Biomechanics
  • Rheumatology
  • Orthopedics

Background:

  • Rheumatoid arthritis (RA) is a chronic inflammatory disease affecting joints.
  • RA can lead to significant functional limitations, including impaired gait.
  • Understanding gait alterations in RA is crucial for managing the condition.

Purpose of the Study:

  • To analyze kinematic and kinetic gait changes in rheumatoid arthritis (RA) patients versus healthy controls.
  • To investigate the association between functional disability (Health Assessment Questionnaire scores) and gait parameters in RA patients.

Main Methods:

  • Utilized a 3D motion analysis system to measure kinematic and kinetic gait parameters.
  • Compared gait data from 50 RA patients and 37 healthy controls.
  • Correlated gait parameters with Health Assessment Questionnaire (HAQ) scores.

Main Results:

  • RA patients showed significantly reduced joint motions (hip, knee, ankle) and joint moments compared to controls.
  • Lower work (positive and negative) was observed in the hip, knee, and ankle joints of RA patients.
  • Fair, though significant, correlations were found between HAQ scores and several gait parameters (e.g., range of motion, moments, stride/step length).

Conclusions:

  • RA patients demonstrate widespread reductions in joint movement, moments, and work during walking.
  • Functional disability in RA has a limited, fair association with specific gait parameters.
  • These findings enhance the understanding of how RA impacts lower limb biomechanics during gait.
