Summary
Measuring the medial longitudinal arch in neutral or relaxed foot positions yields similar results. This study found strong correlations, suggesting one measurement is sufficient for evaluating foot arch characteristics.
Area of Science:
- Biomechanics
- Podiatry
- Orthopedics
Background:
- The medial longitudinal arch is crucial for foot load-bearing and shock absorption.
- Accurate evaluation of the medial longitudinal arch requires specific foot positions.
Purpose of the Study:
- To analyze the correlation between medial longitudinal arch measurements in neutral and relaxed subtalar joint positions.
- To determine if both neutral and relaxed positions are necessary for arch evaluation.
Main Methods:
- A cross-sectional study involving 51 healthy volunteers (102 feet).
- Measurements included navicular height, medial longitudinal arch angle, and Feiss line in neutral and relaxed positions.
- Pearson's correlation test was used to evaluate the relationship between measurements.
Main Results:
- Strong correlations were found for Feiss line (r=0.81), medial longitudinal arch angle (r=0.78), and navicular height (r=0.76) between neutral and relaxed positions.
- These findings indicate high consistency between the two measurement positions.
Conclusions:
- Measurements of the medial longitudinal arch show strong correlations between neutral and relaxed positions.
- Measuring the medial longitudinal arch in only one position (either neutral or relaxed) is sufficient for clinical evaluation.

01:10Ankle Joint
2.1K
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...

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

01:10Bones of the Lower Limb: Tibia and Fibula
6.3K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
