Three-Dimensional Force System01:30

Three-Dimensional Force System

In mechanical engineering, a three-dimensional force system is a system of forces acting in three dimensions, with forces applied along the x, y, and z coordinate axes. The three-dimensional force system is an important concept in mechanical engineering, as it allows engineers to understand and analyze the behavior of objects and structures in three dimensions. By understanding the forces acting on a system, engineers can design more efficient and effective mechanical systems that can withstand...

Three-Dimensional Force System:Problem Solving

A three-dimensional force system refers to a scenario in which three forces act simultaneously in three different directions. This type of problem is commonly encountered in physics and engineering, where it is necessary to calculate the resultant force on the system, which can then be used to predict or analyze the behavior of the object or structure under consideration.
To solve a three-dimensional force system, first resolve each force into its respective scalar components. Do this using...
Bone Remodeling01:40

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

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...
Bone Remodeling and Repair01:31

Bone Remodeling and Repair

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...

Area of Science:

  • Biomechanics
  • Medical Imaging
  • Orthotics

Background:

  • Foot problems necessitate orthotic interventions, often preferring insoles over surgery.
  • Existing insole design relies on static foot measurements, neglecting dynamic use during activities like walking or running.

Purpose of the Study:

  • To design and implement a structured-light 3D imaging system for capturing foot motion.
  • To demonstrate that dynamic foot measurements differ significantly from static measurements.
  • To highlight the importance of dynamic measurements for effective foot orthosis design.

Main Methods:

  • Developed a structured-light prototype system to capture 3D foot measurements from video sequences.
  • Input: video of a foot during a single step. Output: 3D reconstruction of the plantar foot surface per frame.
  • Validated the system with engineering and clinical tests, assessing accuracy and repeatability.

Main Results:

  • System accuracy achieved 0.34 mm with planar objects.
  • Repeatability tests showed average differences of 2.44 mm (static) and 2.81 mm (dynamic) over one week.
  • Dynamic foot reconstructions showed an average increase of 9 mm in effective length compared to static measurements.

Conclusions:

  • Dynamic foot measurements are substantially different from static ones, particularly in effective length.
  • Static measurement systems cannot capture these dynamic changes, which are critical for orthotics.
  • Subject-specific dynamic foot measurements are crucial for designing effective, personalized foot orthoses.
