Lower Extremity Review
A study from Korea has demonstrated that foot intrinsic muscle dynamic stretching training improved dynamic balance, velocity, step lengths, stride length, and dynamic gait index (DGI) in patients with chronic stroke.
Lateral ankle sprains are one of the most common musculoskeletal injuries. Up to 70% of individuals who sustain lateral ankle sprains develop chronic ankle instability (CAI). Exercise therapy is considered an effective treatment for patients with CAI.
“…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.
Knee extensor and flexor muscle (ie, thigh) weaknesses are well-established consequences of anterior cruciate ligament (ACL) tears treated with ACL reconstruction (ACLR). To learn more, Canadian researchers assessed bilateral knee extensor and flexor concentric isokinetic peak torque at 90° per second semiannually in 186 youth (106 injured, 80 controls) for 2 years.
Sarcopenia is characterized by the progressive loss of skeletal muscle mass and poses a significant health challenge for older adults by increasing the risk of disability and decreasing quality of life. With the increasing number of older adults, sarcopenia has the potential to become a major public health burden across the globe. Yoga is considered a low-risk and beneficial exercise for older adults.
Getting at least 30 minutes of daily summer sun in the first year of life may mean a lower relapse risk for children who are diagnosed with multiple sclerosis (MS) later, according to a study published in Neurology Neuroimmunology & Neuroinflammation. The study also found if a child’s biological mother had at least 30 minutes of daily sun during the second trimester of pregnancy, the child had a lower risk of MS relapses.
In this secondary analysis, there was no difference between morning (AM) and afternoon/early evening (PM) exercisers in blood glucose, insulin, body composition, or muscular strength following 12 wk of supervised exercise. However, examining within-group changes, glucose area under the curve (AUC) was significantly reduced in PM exercisers, but not in AM exercisers.
Reductions in balance performance, hip strength, and ankle function along with increases in disablement and injury-related fear are among the many motor-behavioral and sensory-perceptual impairments associated with chronic ankle instability (CAI). Both balance training (BAL) and hip strengthening (HIP) can improve balance, but how do the 2 modalities compare?
