Estimating the paths and mechanical behaviors of the plantar aponeurosis during dynamic movements using a multiple-marker foot model incorporating anatomically-detailed plantar aponeurosis morphology.

Background: Several foot models have been developed to estimate the behaviors of the plantar aponeurosis (PA) during movements. However, these models did not consider the actual path of the PA, and their validity remains insufficiently investigated due to the absence of direct PA measurement during movements.
Research Question: Would developing a foot model that considers the actual path of the PA improve the accuracy of estimating the PA behavior during movements?
Methods: The foot model was developed based on the CT scans of the six feet with 20 markers attached.
Polymers in Physics, Chemistry and Biology: Behavior of Linear Polymers in Fractal Structures.

We start presenting an overview on recent applications of linear polymers and networks in condensed matter physics, chemistry and biology by briefly discussing selected papers (published within 2022-2024) in some detail. They are organized into three main subsections: polymers in physics (further subdivided into simulations of coarse-grained models and structural properties of materials), chemistry (quantum mechanical calculations, environmental issues and rheological properties of viscoelastic composites) and biology (macromolecules, proteins and biomedical applications). The core of the work is devoted to a review of theoretical aspects of linear polymers, with emphasis on self-avoiding walk (SAW) chains, in regular lattices and in both deterministic and random fractal structures.

Design of a custom metamaterial insert for improved pressure distribution within transtibial prosthetic sockets.

Department of Bioengineering, Clemson University, Clemson, SC, USA.
Uneven pressure distribution within a transtibial prosthetic socket can lead to discomfort, skin degradation, and suspended prosthesis use. Current custom interfaces to improve pressure distribution are often costly, time-intensive to fabricate, or cannot be incorporated into standard socket fabrication methods. In this technical note, we describe the design and preliminary clinical evaluation of a novel transtibial prosthetic socket insert with modifiable mechanical properties, which can be incorporated into the current clinical cycle of care.
