Classification: CPC G  A  C | IPC A  C  G

Claim 0:
1. A method of treating a subject in need thereof comprising:
(a) classifying the subject into functional group FG1, FG2 or FG3, wherein classifying the subject comprises:
(i) determining changes in cellular impedance following Gi-stimulation, wherein a reduction of cellular impedance of more than 60 and up to 90% relative to a non scoliotic subject classifies the subject into FG1, a reduction of cellular impedance of 40-60% relative to a non scoliotic subject classifies the subject into FG2; and a reduction of cellular impedance of 10-40% relative to a non scoliotic subject classifies the subject into FG3;
(ii) measuring changes in cAMP concentration following Gi-stimulation, wherein a cAMP increase relative to baseline cAMP concentration following forskolin stimulation classifies the subject into FG1, no significant change relative to baseline cAMP concentration following forskolin stimulation classifies the subject into FG2; and a cAMP decrease relative to baseline cAMP concentration following forskolin stimulation classifies the subject into FG3; or
(iii) determining the phosphorylation pattern of Giα proteins, wherein phosphorylated Giα1, Giα2 and Giα3 classifies the subject into FG1; phosphorylated Giα1 and Giα2 and unphosphorylated Giα3 classifies the subject into FG2; and phosphorylated Giα2 and Giα3 and unphosphorylated Giα1 classifies the subject into FG3; or
(b) measuring the level of osteopontin (OPN) in a blood sample from the subject; and
(c) (c-i) selecting a subject classified into the FG2 or FG3 functional group, and treating that subject with a brace; or
(c-ii) selecting a subject classified into the FG1 functional group, and having a level of OPN in his or her blood sample below 500 ng/ml, and treating that subject with a brace for 1 to 6 months.
