This is a review article including a selected collection of new articles extracted from PubMed and Google Scholar searched for clinical points and beneficial approaches to limping children. In this paper, limping is divided into two categories, painful and painless. After stating the important points in the patient’s medical history and explaining specific examinations in this area, different gait types in children are explained and the best evaluation method for them is presented. Then, paraclinical examinations and imaging are described in a practical evaluation, high-risk etiologies of limping such as infections, tumors, and fractures are explained in detail and red flags are considered at each step. The algorithms and the list of differential diagnoses for each age group are included, which can provide physicians with a more comprehensive approach to limping in children.展开更多

It involves expensive hospitalizations, often resulting in an amputated lower limb. We explored a variety of methods treating neuropathic pain such as low-level laser, monochromatic near-infrared treatment, TENS, acupuncture and pulsed electromagnetic fields that demonstrated inconclusive, limited or temporary pain relief with minor or short-term improvements in mobility. Research conducted by ultra-low energy technologies reports pain relief and reduction of inflammation as a result of anti-oxidant electron donation transforming free radicals into stable molecules. We report the results of a randomized double blind one-year-long longitudinal clinical study on 10 diabetic mellitus (DM) subjects with chronic neuropathy, treated with ultra-low energy nanotechnology who experienced substantial long-term neuropathic pain relief. Importantly, pain analgesia and improvement in neuropathic symptomatology were not age-contingent. This contradicts past research postulating that age-accumulated inflammation and endothelial dysfunction can further exacerbate diabetic neuropathy. Importantly, a method offering age-independent, cost-effective, long-term neuropathic pain relief and increased mobility has major implications in reducing hospitalization time and overall expenses by offering a solution that enhances quality of life.展开更多

In addition, a theoretical model is proposed for the electrostatic induction current generated owing to variation in the electric potential of the human body. The proposed electrostatic induction current model is compared with the theoretical model, and the proposed model is shown to effectively explain the behavior of the electrostatic induction current waveform. The normal walking motions of daily living are recorded with a portable sensor located in a regular house. The obtained results show that detailed information of physical activity such as a gait cycle can be estimated using our proposed technique. Additionally, the walking signal was measured when the subject walked with the ankle and knee fastened to a splint with bandages to simulate a limp. Therefore, the proposed technique, which is based on the detection of signal generated during walking, can be successfully employed to assess human physical activity.展开更多

We report on a 43-year-old woman with melorheostosis who had pain in the upper limp for 10 years, limitation of joint movement and a deformity in the left third finger. Radiographies and bone scintigraphy were evaluated. All lesions of melorheostosis in radiography were seen in bone scintigraphy. More than half of increased uptakes on bone scintigra-phy are due to degenerative process.展开更多
