From the Expanded Edition (2013), pp. 26f., italics in the original:
"He told us his problem was carpal tunnel syndrome. ... [W]e laid our hands on his wrists, commanding the tunnel to open and all numbness and pain to be gone."
But there is nothing "closed" in carpal tunnel syndrome which needs "opening".
The idea of "opening" reflects a misunderstanding of a treatment method in which the name given to a treatment technique has been transposed to a misconceived description of a healthy outcome.
Apart from the non-invasive treatment methods which are initially preferred because about a third of cases self-correct anyway without treatment, the last resort is surgery, either the more invasive open carpal tunnel release surgery, or the less invasive endoscopic carpal tunnel release surgery.
The identical object of both surgical techniques is to get in there and sever a ligament which puts pressure on the nerve causing the numbness and pain.
You either open up the wrist in the traditional manner with a scalpel, or go in through a much smaller incision with an endoscope equipped with smaller cutting instruments.
