NS Health Pain Therapy Clinic

NS Health is a pain therapy clinic using and distributing medical device products under the brand names medkey, physiokey, and sanakey. These are based on an exceptionally efficient form of pain therapy – bioadaptive impulse therapy. It’s a non-pharmacological therapy effective in reducing pain, reducing swelling and inflammation, and reducing muscular spasm and as a result giving improved function, flexibility, and accelerated healing time.

NS Health. We bridge the gap for effective pain relief.

Everything that happens within our body is the result of either a chemical or an electrical message. By taking pharmaceuticals, herbs or supplements we are looking for a response from the chemical system. At NS Health we bridge the gap by using bioadaptive impulse therapy to affect the body’s electrical system: intrinsic within our body’s pain messaging and response.

NS Health. Established pain therapy clinic since 2005 with proven treatment methods and results.


Based in Dee Why, on Sydney’s northern beaches, NS Health is sought out by the general public as well as elite sportsman and Olympic and World champions as we provide outstanding results for both acute and chronic injuries and painful conditions alike.

A referral for an appointment is not necessary.
