Trial Outcomes & Findings for A Crossover Study on the Blinding Effect of a New Pragmatic Placebo Needle (NCT NCT01948375)
NCT ID: NCT01948375
Last Updated: 2018-01-09
Results Overview
The primary outcome was the proportion of volunteers'perception of needle penetration between the placebo needle and the real needle in the third acupuncture session in each period. LI4, on the dorsum of the hand, between the first and second metacarpal bones, approximately in the center of the second metacarpal bone; RN12, on the upper abdomen,4 cun above the umbilicus,on the anterior midline; BL36, on the back of the thigh,on the midpoint of the inferior gluteal crease; BL25, on the loin, 1.5 cun lateral to the lower border of the spinous process of the fourth lumbar vertebra.

Real Needle- Placebo Needle
Participants will accept acupuncture with real acupuncture needle in the first period, and pragmatic placebo needle in the second period of the trial.
real needle- placebo needle: Participants will accept acupuncture with real needle in the first period and pragmatic placebo needle in the second period. Acupoints are to be needled 1 cun by real needle in the first period, and pressed against the skin with no penetration by placebo needle in the second period. For each intervention, LI4 and RN12 are needled first in a supine position for 15 minutes; BL36 and BL25 are needled secondly in a prone position for another 15 minutes. After withdrawal of the needle, participants will be asked questions on skin penetration of needles, needling pain and needle sensation. The acupuncture treatment is given every other day. There are three sessions for each kind of needle, six sessions in total for each participant. There is a two-day interval between two kinds of interventions.

Placebo Needle - Real Needle
n=30 Participants
Participants received acupuncture with pragmatic placebo needle in the first period, and with real acupuncture needle in the second period.
All acupoints were needled through the pad but just pressed against the skin without penetration by pragmatic placebo needle, while through the pad and into the skin 15 mm by real needle. For each intervention, LI4 and RN12 are needled first in a supine position for 15 minutes; BL36 and BL25 are needled secondly in a prone position for another 15 minutes. After withdrawal of the needle, participants were asked to give answers on perception of skin penetration, needle sensation and acupuncture pain. Acupuncture was given every other day, three sessions for one kind of needle, six sessions in total for each subject. There was a two-day interval between the applications of two kinds of needles.

SECONDARY outcome
Timeframe: in the third acupuncture session in each periodThe pain of acupuncture is assessed using visual analogue scale (VAS), where 0 means no pain, and 10 means the imaginable severest pain. The VAS value of each period is used to compare the difference of acupuncture pain between the placebo needle and the real needle. A lower value represented a better outcome, which indicated that needles used induced less pain.

The needle acceptability between the placebo needle and real needle are compared. Data of the acceptability of the placebo needle included rows 1-5, i.e., rows of "placebo needle: very difficult to accept", "placebo needle: a little difficult to accept", "placebo needle: acceptable", "placebo needle: easy to accept" and "placebo needle: very easy to accept". Data of the acceptability of the real needle included rows 6-10, i.e., rows of "real needle: very difficult to accept", "real needle: a little difficult to accept", "real needle: acceptable", "real needle: easy to accept" and "real needle: very easy to accept".
