Is there a cure for Tietze Syndrome?

I came across this website about Tietze’s Syndrome

Can someone explain the treatment section of this article in layman’s terms?

Especially these two sentences:
”* An adjustive technique which involves placing the doctor’s hands along the rib, from the sternum to the spine, thrusting either cephalad or caudad depending on the fixation, counter to the breathing.

* An activator treatment may help.”
