Inverse C7-T1

Defenition: Inverse C7-T1 is defined as equal or less mobility in motion segment C7-T1 compared with T1-2.

Clinical aspects of inverse C7-T1

The inverse C7-T1 dysfunction involves motion segments having a close relationship to the Stellate ganglion.  Dysfunction in this this region  relates to a variety  of symptoms and conditions in the head, neck and arms. Research has shown a significant relationship to mental stress and our clinical experience  has recognized a relationship to sympathetically mediated pain.

A TYPICAL INVERSE C7-T1 FUNCTION. A RISK FACTOR FOR NECK-SHOULDER PAIN
THE INVERSE C7-T1 PROVOKES THE STELLATE GANGLION.

Permanent compensation pattern

Inverse C7-T1 is a predictor of neck-shoulder pain (NSP). It is more frequent among female subjects. Having a permanent inverse C7-T1 presents an elevated risk of NSP (RR 3.1, CI 95% 1.1-6.9) and yields a positive predictive value of 84%.
