Orthoses are commonly used for treating injuries to improve the quality of life of patients, with customized orthoses offering significant benefits. Additive manufacturing, especially fused deposition modelling, enhances these benefits by providing faster, more precise, and more comfortable orthoses. The present study evaluates nine polymeric materials printed in horizontal and vertical directions by assessing their performance through compressive, flexural, and tensile tests. Among all materials, polycarbonate, polylactic acid, and ULTEM 1010 showed the most promising results, not only because they had the highest mechanical values, but also due to their minimal or no difference in performance between printing directions, making them advantageous in orthoses fabrication. Based on this, a finite element model of an ankle-foot orthosis was developed to simulate the deformation, strain, and stress fields under static conditions. The findings aim to optimize material selection for orthotic fabrication, where ULTEM 1010 is presented as the material with improved performance and durability.

Sever's disease (calcaneal apophysitis) is a common cause of heel pain in physically active children. It results from repetitive stress on the calcaneal growth plate during adolescence. This literature review synthesizes evidence from 17 different peer-reviewed studies from PubMed using the terms "Sever's disease" and "calcaneal apophysitis.

Additive manufacturing enables the rapid production and customization of ankle-foot orthoses (AFOs), offering substantial advantages over traditional fabrication methods. Understanding the mechanical properties of these devices, particularly stiffness and deflection during ambulation, is essential for their effective deployment as it may inform future benchtop performance tests, such as fatigue life analysis. However, previous studies seemingly disregard the combined effects of the passive and active ankle joint contributions to stiffness during ambulation, limiting the predictive accuracy of the mechanical performance tests.

Background: The efficacy of the different shoulder orthoses available to prevent hemiplegic shoulder complications still remains debatable.
Objectives: To evaluate how wearing a custom-made (CM) shoulder sling affected personal goals and complications among hemiplegic stroke patients undergoing realworld rehabilitation.
Methods: A prospective, single-center, non-randomized, pilot study on patients having a stroke within the last 6 months with hemiplegic shoulder pain/subluxation >5 mm.

Purpose: This study explores the impact of foot orthoses (FO) on pain and disability in low back pain (LBP) patients, providing new treatment evidence.
Methods: A systematic search was conducted across PubMed, Cochrane Library, Scopus, Web of Science, Embase, Medline, CNKI, and Wanfang Database for randomized controlled trials (RCTs) on FO for LBP treatment, from database inception to July 12, 2025. Data extraction, quality assessment, subgroup analysis, and meta-analysis were performed.

Background: Minor lower extremity amputations (LEA) compromise postural control and increase the risk of falls. This issue is exacerbated by conditions such as diabetes, which affect proprioception and sensorimotor mechanisms. While orthopedic devices, including prostheses and orthoses, are frequently prescribed, their specific role in restoring postural control remains underexplored.
