nshealth is Australia’s leading pain and recovery clinic using bioadaptive impulse therapy with physiokey and sanakey.

we can help!

At NS Health, our emphasis is on resolving the source of the pain, not merely masking or covering it up.

Our therapy may be effective in reducing pain, reducing swelling and inflammation, and reducing muscular spasm and as a result giving improved function, flexibility, and accelerated healing time.

From humble beginnings in 2005 we have pioneered the bioadaptive impulse therapy clinic concept, operating a successful specialist pain relief clinic in Sydney. 

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

A referral for an appointment is not necessary.
