Lower Extremity Review
Writing in Seminars in Musculoskeletal Radiology, 2 European experts review typical anamnestic/clinical findings, epidemiology and risk factors, imaging characteristics, and findings at typical locations of bone stress injuries in the foot and ankle that may help guide treatment strategy and patient recovery.
One in 10 early deaths could have been prevented if everyone had met just half the recommended weekly target of 150 minutes of moderate intensity physical activity, according to the largest pooled data analysis of its kind.
Sarcopenia is associated with adverse outcomes in elderly persons, including functional disability, falls, and even death. Therefore, older adults should be routinely screened for sarcopenia. Due to the unsatisfactory sensitivity of the SARC-F questionnaire, 4 modified versions have been elaborated: SARC-CalF (calf measurement)…
The American College of Rheumatology (ACR) and the American Association of Hip and Knee Surgeons (AAHKS) released a summary of the new guideline for hip and knee replacement timing titled “The Optimal Timing of Elective Hip or Knee Arthroplasty for Patients with Symptomatic Moderate to Severe Osteoarthritis or Osteonecrosis Who Have Failed Nonoperative Therapy.”
Background: First available in the United States (US) in 2015, hoverboards have become popular, with millions purchased. There is risk of injury when operating hoverboards. This study characterized hoverboard-related lower extremity injuries treated at United States (US) emergency departments (EDs).

Hoverboard continues to be an increasingly popular ride option for all ages. But these rechargeable self-balancing scooters with electric motors and batteries require serious attention to safety. Designed for personal transportation, today’s hoverboards can reach speeds of 10 mph, with the average clocking in at 7 mph.

Plantar fasciopathy pain forces individuals to make adjustments in physical activity leading to reduced quality of life. Plantar fasciopathy (PF) is the most common cause of heel pain, and is associated with decreased physical activity level and quality of life. There has been limited research on the experiences of patients with PF.

Chronic ankle instability—a recurring “giving way” of the lateral (outer) side of the ankle causing instability—results from repeated ankle sprains. These authors aimed to find a test battery that could be used easily and could discern true injury in this special population.

This chapter concerns the study of gait from an office setting, the understanding of what is considered normal, and the symptoms related to gait variations. In my training, gait evaluation was a crucial part in assessing how the [orthotic device] worked in controlling excessive motion, correcting for a short leg, improving someone’s posture, but also in spotting all sorts of problems.

Researchers at The Ohio State University (Ohio State) have fabricated the first wearable sensor designed to detect and monitor muscle atrophy. Allyanna Rice, a graduate fellow in electrical and computer engineering and Asimina Kiourti, PhD, a professor in electrical and computer engineering, designed the device to work by employing 2 coils…
Singapore University of Technology and Design (SUTD) researchers have developed a fully knitted, circuit-embedded knee wearable for wireless sensing of joint motion in real time. Compared to other knitted electronics, this model has fewer externally integrated components and a more sensitive sensor. The innovation is a collaboration between…
A new portable, flexible, and user-friendly ankle exosuit has been designed for autonomous usage and has the capacity to assist stroke survivors in enhancing their walking capabilities beyond laboratory settings and in their everyday routines. The ankle exosuit has been shown to aid stroke survivors in improving their walking propulsion…
Using electric stimulation, researchers in a project at Chalmers University of Technology, Sweden, and the University of Freiburg, Germany, have developed a method that speeds up the healing process, making wounds heal 3 times faster. The work has implications for elderly people and those with diabetes.
A team of engineers at the University of California San Diego has developed a stretchable ultrasonic array capable of serial, non-invasive, 3D imaging of tissues as deep as 4 centimeters below the surface of human skin, at a spatial resolution of 0.5 millimeters. This new method provides a non-invasive, longer-term alternative to…
