Pulsed electromagnetic field (PEMF) as an adjunct therapy for pain management in interstitial cystitis/bladder pain syndrome.

Int Urogynecol J 2021 Jun 8. Epub 2021 Jun 8.

Wake Forest Institute for Regenerative Medicine, Wake Forest Baptist Medical Center, 391 Technology Way, Winston Salem, NC, 27101, USA.

Introduction And Hypothesis: Patients with interstitial cystitis/bladder pain syndrome (IC/BPS) often experience chronic pelvic and even systemic pain that can be difficult to clinically manage. Pulsed electromagnetic field (PEMF) therapy, a non-invasive strategy that has shown significant efficacy for pain reduction in other chronic pain conditions, may provide benefit for pain management in patients with IC/BPS.

Methods: PEMF delivery to patients occurs via a bio-electromagnetic-energy device which consists of a flexible mat (180 × 50 cm) that the patient lies on for systemic, full-body delivery and/or a flexible pad (50 × 15 cm) for targeted delivery to a specific body region (e. Read More

The role of viscosupplementation in patellar chondropathy.

Ther Adv Musculoskelet Dis 2021 13;13:1759720X211015005. Epub 2021 May 13.

Knee Surgery Division, Instituto de Ortopedia e Traumatologia, Hospital das clínicas HCFMUSP, Faculdade de Medicina, Universidade de São Paulo, São Paulo, SP, Brazil.

Patellar chondropathy has a high incidence in the general population, being more common in patients younger than 50 years, female and recreational athletes, and overweight and obese patients. The most common complaints are pain, limited mobility, crepitus, difficulty climbing and descending stairs, and joint instability, usually showing unsatisfactory results with anti-inflammatory, physiotherapy, rehabilitation, and many other conservative treatment methods. The presumed hyaluronic acid (HA) disease-modifying activity may include effects on cartilage degradation, endogenous HA synthesis, synoviocyte and chondrocyte function, and other cellular inflammatory processes.

Auxiliary Diagnostic Method for Patellofemoral Pain Syndrome Based on One-Dimensional Convolutional Neural Network.

Front Public Health 2021 16;9:615597. Epub 2021 Apr 16.

College of Physics and Information Engineering, Fuzhou University, Fuzhou, China.

Early accurate diagnosis of patellofemoral pain syndrome (PFPS) is important to prevent the further development of the disease. However, traditional diagnostic methods for PFPS mostly rely on the subjective experience of doctors and subjective feelings of the patient, which do not have an accurate-unified standard, and the clinical accuracy is not high. With the development of artificial intelligence technology, artificial neural networks are increasingly applied in medical treatment to assist doctors in diagnosis, but selecting a suitable neural network model must be considered.
