Lower Extremity Review
“…In one analysis of sedentary behavior, participants were found to spend 14 hours sitting each day. In the NHANES nationally representative survey, the self-reported number of hours spent sedentary in 2007-2008 was 5.7, and this increased to 6.4 hours per day for 2015 – 2016 (Du et al 2019). Using accelerometry-derived data, U.S.
This study forms the basis of a digital twin system of the knee joint, using advanced quantitative MRI (qMRI) and machine learning to advance precision health in osteoarthritis (OA) management and knee replacement (KR) prediction. The study authors combined deep learning–based segmentation of knee joint structures with…
A new study from China looked at changes in neuromuscular control in elderly adults with hallux valgus to better understand the increased risk of falls in this population. The researchers assessed gait using non-negative matrix factorization (NNMF) for electromyography (EMG) and joint motion to compare muscle and…
Titanium plantar plates have proven successful in the fixation of the first tarsometatarsal arthrodesis (TMT). However, a second surgery is typically needed for implant removal, and potential adverse effects, carried by the conventional implantations, are not uncommon. The purpose of this study was to determine whether…
An international team of researchers compared lower limb mechanics and muscle activation during walking at self-selected speed under 3 randomized conditions: 5° medial rearfoot posting, 5° medial rearfoot and forefoot posting, and a control flat insole.
One of the important problems for mothers after the birth of a premature infant is a decrease in milk production. This study aimed to investigate the effect of foot reflexology on the volume and composition of breast milk in mothers of premature infants hospitalized in the neonatal intensive care unit.
About 1 in 5 adolescents in the U.S. has obesity. Lifestyle changes, such as physical activity and dietary changes, are often the first choice for treating childhood obesity. If that doesn’t work, medications or weight-loss surgery, also called metabolic and bariatric surgery, may also be considered.
Sport Sciences researchers from Waseda University in Japan sought understand injuries in female university soccer players. Their prospective study investigating injuries in this population over 3 seasons was recently published in the International Journal of Sports Physical Therapy.
My Toe Can’t Go was born from heartbreak and urgency, said children’s author Hillary Duncombe, MS. “Watching my sister suffer the devastating effects of type 2 diabetes mellitus (T2DM) and polyneuropathy—leading to a series of amputations—was unbearable.” Within a month, her sister lost her toes, midfoot, and finally her leg before succumbing to the disease. Before she died, her young daughter would tearfully ask, “Why is this happening to my mummy?”

Firefighter footwear is subject to a host of regulations, primarily set by the National Fire Protection Association (NFPA) – but selected by the local authority for fire jurisdiction. This footwear is designed to provide adequate protection against multiple hazards encountered during firefighting as well as…
Performing a biopsy is crucial for achieving diagnostic accuracy. Podiatric physicians may biopsy less frequently than their dermatology counterparts, but an earlier biopsy can significantly improve patient care. Many skin conditions can mimic common podiatric issues, and a biopsy allows for histopathological examination, which can…

It’s a physics problem – We live dynamic lives, in turn, we suffer dynamic consequences! In the last installment, we focused on our problematic anatomy. We continue this discussion by looking at what happens when we add the interaction between 2 dissimilar bodies, the foot and the floor, and the introduction of force.

Background: In 2020, there were over 1 million career and volunteer firefighters in the United States (US). Thousands of injuries involving firefighters occur annually. The body part involved in the highest proportion of injuries is the lower extremity. The objective of this study was to characterize firefighter lower extremity injuries in the US.

Dynamic knee valgus, a highly reliable measure of this alignment assessed in the frontal plane, is a valuable tool for identifying this pathomechanical dysfunction. The purpose of this study was to investigate the effectiveness of functional hip abductor strength training on reducing contralateral pelvic drop angle…

A gait training robot, developed through collaborative efforts from institutions including the University of Chinese Academy of Sciences and the Institute of Automation at the Chinese Academy of Sciences, is designed to significantly improve the safety and effectiveness of gait training through a novel method…
