The Schroth Method is a physiotherapeutic treatment system which uses isometric and other exercises to strengthen and lengthen asymmetrical muscles in a scoliosis patient. The goal of the Schroth Method is to halt curve progression, reduce pain, increase organ capacity, partly reverse abnormal curvatures, improve posture and appearance, maintain improved posture, and avoid surgery. Because the Schroth Method relies on exercises it is limited in the permanence of the change to the spine it can provide. Please see here for a list of equipment required etc.
Aside from Larry Cohen at Postural Physiotherapy in Sydney, who we have first hand knowledge of and is excellent, please see here for another source of Schroth practitioners across Oceania.
There is a gentleman on the Schroth practitioners from Auckland; Jason Kim - his website is : www.physiolink.co.nz
Another organisation known to our group, this time in Melbourne, is Rebecca Harding from Scoliosis Physiotherapy.
