Acupuncture Versus Sham for Radiotherapy-Induced Emesis

"Acupuncture was administered bilaterally to the standard antiemetic point2-4 pericardium six (PC6) located between the tendons of palmaris longus and flexor carpii radialis at two body-inches proximal of the wrist crease. Sharp needles, diameter 0.25 x length 40 millimetres, were inserted into a depth of a half body-inch. One body-inch (or a cun in traditional Chinese medicine context) is equivalent to the greatest width of the individual patients´ thumb at the distal phalanx, approximately one and a half centimetres or one American thumb. The needles were manipulated three times (at the start, middle and end of the treatment session) by twirling, thrusting and lifting until deqi occurred."

Sham acupuncture was administered bilaterally to a non-acupuncture point two body-inches proximal of PC6 with the telescopic Park sham device16, 0.30 x 40 millimetres (fully extended length). That needle looks identical with a real needle but is blunted and glides upwards into its handle instead of penetrating, which gives an illusion of penetration. The marking tubes hold the needles in place. The therapist gave an illusion of manipulation by turning the needle three times, each time for a couple of seconds until the needle touched the skin, but no deqi occurred. Except when placing and manipulating the sham needle, it was not pressed against the skin at all.
