Pulsed electromagnetic field (PEMF) has been successfully applied to accelerate fracture repair since 1979. Recent studies suggest that PEMF might be used as a nonoperative treatment for the early stages of osteonecrosis. However, PEMF treatment requires a minimum of ten hours per day for the duration of the treatment. In this study, we modified the protocol of the single-pulsed electromagnetic...

BACKGROUND Osteoarthritis (OA) is the final result of progressive alterations to articular cartilage structure, composition and cellularity, followed by an increase in the concentration of pro-inflammatory cytokines in joint synovial fluid. Even though the effect of pulsed electromagnetic field (PEMF) stimulation in counteracting OA progression and inflammation is of increasing interest, becaus...

A osseointegração entre implante e tecido ósseo receptor deve ocorrer adequadamente, sendo a integração óssea chave do sucesso cirúrgico. No entanto, os implantes presentes no mercado normalmente requerem 2 6 meses sem carga dispositivo para permitir tempo suficiente osseointegração. Nos últimos anos, tem sido investigado o uso de pulsos eletromagnéticos (PEMF) como tratamento visando melhorar ...

The issue of pain treatment is an extremely urgent health and socio-economic problem. Pain, in acute, recurrent and chronic forms, is prevalent across age, cultural background, and sex, and costs North American adults an estimated $10,000 to $15,000 per person annually. Estimates of the cost of pain do not include the nearly 30,000 people that die in North America each year due to non-steroidal...

The purpose of this study was to evaluate whether 50 Hz extremely low frequency electromagnetic fields (ELF-EMFs) affect the amount of orthodontic tooth movement in rats. The experiments were performed on 18 male Sprague-Dawley rats. The rats were randomly divided into three groups (n = 6): cage-control (Cg-Cnt) group (n = 6); sinusoidal electromagnetic field (SEMF) group (n = 6); and pulsed el...

Objective To investigate changes in nucleus pulposus cell expression and secretion of interleukin (IL)-1β and tumour necrosis factor (TNF)-α following stimulation with a low-frequency (LF) pulsed electromagnetic field (PEMF). Methods Primary rat nucleus pulposus cells were isolated and cultured in vitro, followed by stimulation with LF-PEMFs at a frequency of 2 Hz and different intensities, ran...

PURPOSE The aim of the present study was to evaluate the effect of a pulsed electromagnetic field on the healing of mandibular fractures. Pulsed electromagnetic fields have been shown to accelerate healing of fractures of the long bones. PATIENTS AND METHODS A total of 12 patients with mandibular fractures were selected for the present study. Each patient was treated by closed reduction using...

Delivery of health care demands evidence-based practice. Evidence-based practice helps to ensure that all facets of health care delivery are subject to a higher level of accountability. This helps to assure that the patient is receiving treatment that has some proof of efficacy. In recent years, physiotherapy practice has been influenced by a swell of research which, in many cases, supports cur...
