PEMF uses keep expanding, NASA Cartilage Regeneration

Noninvasive Therapy for Cartilage Regeneration (MSC-TOPS-96)

Overview
Innovators at NASA Johnson Space Center researching time-variance magnetic field (TVMF) therapies have developed a pulsed electromagnetic field (PEMF) device that can alleviate cartilage degradation in synovial joints by promoting the growth of new cartilage. Joint disorders, whether induced by rheumatism, joint dysplasia, trauma, or surgery, often degrade cartilage and result in intense patient pain. Noninvasive and painless regeneration of a patients own tissue offers fewer side-effects than surgical joint replacement or tissue engineering procedures. The PEMF device could simply be wrapped around synovial joints where cartilage-degrading inflammation is located. This pulsed electromagnetic field technology is at a technology readiness level (TRL) 6 (system/sub-system model or prototype demonstration in an operational environment) and the related patent is available for licensing. Please note that NASA does not manufacture products itself for commercial sale.
