Referring to the previous article that Ive taken from WEB PT : here's a brief summarization on what is GPR

Global Postural Re-education (GPR) The technique is known as Souchard's Global Postural Re-education and it employs a series of gentle movements to realign spinal column joints and strengthen and stretch muscles that have become tight and weak from underuse.
It was developed in France 25 years ago, GPR is only now being introduced in the United States.


This treatment, which has been successfully used in Europe for many years, follows the same principal as other muscle-release, posture retraining techniques.
GPR because is becoming accepted by mainstream doctors. Internet searches for the term “GPR,” brings up mainly Orthodox medical sites. You might note these sites make no mention of any other similar treatments that have been around in North America for years.
Most importantly, anything that helps to recognize "muscle release therapy" is a very good thing, and we never look a gift horse in the mouth. No matter how this highly successful treatment method is brought out of the dusty closets of practicing physicians it will prove of immense benefit to the hundreds of millions of people who make up that 95% of back and neck pain for which there is no apparent diagnosis.
