Alternative treatments for osteoarthritis?

I recently read that in laboratory tests, electromagnetic field (EMFs) have been shown to stimulate the growth of bone and cartilage.

In one clinical study, people with osteoarthritis of the knee were given 48-minute sessions of either extremely low EMFs to the knee for two weeks or a placebo treatment. The results were very clear-cut: 46 percent of patients receiving the real treatment found their pain levels were reduced compared to 8 percent with the sham procedure.

Although the evidence is still relatively sparse, a 2013 review of the available data confirmed that EMF therapy "may provide moderate benefit for osteoarthritis suffers in terms of pain relief".

Pulsed EMF (PEMF) generators - which include low-power, wearable devices designed for virtually continuous use as well as high-power machines meant to be used several times a day - may be able to help osteoarthritis sufferers by apparently increasing blood flow to areas exposed to the EMFs and also be having a positive effect on pain.

I have been using PEMF technology for nearly five years which has dramatically helped me. I was wondering if anyone else had used PEMF, or any other alternative treatments for osteoarthritis. You can read my story at https://beatingosteoarthritis.co.uk
