The week before Thanksgiving I attended a lecture and demonstration on using contact needles for cancer treatment related pain by Dr. Keiko Ogawa of Kanazawa, Japan. Dr. Ogawa published a study in 2013 on using contact needles to treat chemotherapy-induced peripheral neuropathy (CIPN). I was excited to see research on contact needles available in English and to learn this was the first time she was teaching in the US. There is a wealth of research on contact needle therapy in Japanese, but most of it has not been translated for a Western audience.
I often use a specialized silver contact needle tool in my treatments. Dr. Ogawa performed her study using disposable silver needles more similar to the stainless steel needles we use for insertion needling. Regardless of the tool, the method is to settle the needle on the relevant acupuncture point rather than inserting the needle into the skin. This is a painless form of treatment that has the added benefit of reducing infection risk, a key feature in treating cancer patients who may have weakened immune systems due to their cancer and/or their Western treatment (chemotherapy, radiation, etc).
