The Cyriax system is used extensively in the Netherlands for the treatment of spinal injuries. As a patient, I can attest that in 20 to 30 minutes, using this system my therapist would remove the pressure from my herniated disks, massage away the inflamation from the surrounding tissue, properly align my vertebrae to allow blood to flow into my leg, completey removing my pain though I would often enter his office on crutches. After two months of treatments I was symptom free until I reinjured myself in an industrial accident. I'm not exaggerating. I haven't been able to find anyone in Southern California who knows this system as they do in Europe which led me here where I can purchase the book myself. If you're a chiropractor or physical therapist and you really want to help your patients, you need to know this.
