AI Article Synopsis
- - Prolonged standing can lead to foot disorders, and standard safety shoes don't help mitigate this issue, prompting the study of custom foot orthoses for workers.
- - Thirty-four workers with foot pain participated in the study, receiving 3D-printed orthoses designed by a podiatrist, with measurements taken before and after three weeks of use.
- - Results showed significant reductions in pain and discomfort, improved balance, and a shift in foot pressure distribution from the heel to the midfoot, indicating increased well-being for standing workers.
Article Abstract
Background: The prolonged standing position is an important factor in the onset of foot musculoskeletal disorders among workers. Safety shoes, designed to protect against the physical constraints of the work environment, do not address this issue to date.
Objectives: The goal of this study is to assess the possible benefits of custom-made foot orthoses among prolonged standing workers.
Study Design: repeated measures without control group.
Methods: Thirty-four standing workers who suffer from foot pain volunteered for the study. Custom-made foot orthoses, designed by a podiatrist, were 3D-printed and distributed to each volunteer. Static balance as well as static and dynamic plantar pressure measurements were carried out with sensors inserted in the safety shoes, before and after three weeks of wearing foot orthoses daily. A questionnaire on pain and comfort was also distributed before and after treatment.
Results: Feelings of pain, discomfort and heavy legs were found to be significantly reduced after wearing 3D-printed orthoses (p<0.05). Additionally, in static and dynamic conditions, a significant decrease in mean peak pressure in the rearfoot area was observed along with a significant increase in mean peak pressure in the midfoot area (p<0.05). There was also a significant improvement of balance in the medial-lateral direction.
Conclusion: Custom-made orthoses significantly increase the well-being of standing workers in our experimental testing conditions. The custom-made shape allows for a better balanced distribution of foot peak pressure thanks to its support and stimulation of the foot arches particularly through a shift of pressure from the heel to the midfoot.

Background: Charcot-Marie-Tooth (CMT) is a progressive disease resulting in distal sensory deficit and muscular weakness. As the disease progresses, most children develop a cavovarus foot deformity. Foot orthoses (FO) are widely prescribed in CMT to support the foot and improve gait, but there is a lack of guidelines for their conception.

Background: An important part of the orthotic treatment process includes performing adjustments to the shape or design of the orthosis to improve its fit and function. However, the ability to adjust 3D printed (3DP) materials is not well understood.
Objectives: (1) To evaluate the usability of completing adjustments on 3DP ankle foot orthoses (AFOs) vs.

Background: Foot orthoses have been considered to affect static and dynamic functional capacity and could help older adults maintain balance while walking. However, the impact of textured foot orthoses over co-contraction strategies remains uncertain. Therefore, this study aimed to assess the effect of different textured foot orthoses on ankle and knee joint muscle co-contraction in male and female older adults during walking.

Background: Patellofemoral pain (PFP) is a common knee condition in young and active individuals that is managed with highly variable treatment strategies.
Objective: To determine whether the length, number of visits, and content of physical therapy care for patients with PFP differ between a Clinical Practice Guidelines (CPG) adherent program and usual care. Additionally, the percentage of patients reporting clinically important improvements in patient-reported outcomes in each group was evaluated as an exploratory aim.

Purpose: This study aims to evaluate a new method for the five times sit to stand test (FTSST), crucial for addressing frailty in an aging population. It utilizes a smart insole for plantar pressure analysis and a marker-less motion capture device for head height analysis.
Materials And Methods: Thirty-five participants aged 50 years or older underwent FTSST assessment using three methods: manual measurement with a stopwatch (FTSST-M), plantar pressure analysis with smart insoles (FTSST-P), and head height analysis with a marker-less motion capture device (FTSST-H).
