Osteoarthritis (OA) is a growing problem in animals. Assisi is marketing technologies that have been demonstrated to provide pain relief in human OA of the knee.1 There is existing evidence that PEMF therapies of several types may improve the progression of OA and underlying health of cartilage. Studies suggest that use of PEMF can slow the progression of OA in animals2 and have positive effects on cartilage cells directly.3 Targeted signals modulate chondrocyte proliferation through a pathway which is mediated by nitric oxide.4 This is the same pathway through which Assisi’s technology decreases inflammation and enhances healing.5
The use of a standard PEMF technology (not Assisi), produced the significant preservation of cartilage (in pink) in a model that treated animals one-hour a day. Treated animals had a third less progression of OA1.
