Acupuncture for Functional Constipation in Older Adults

All acupoints will be routinely sterilized at first. After the insertion of the needles, manipulations of lifting, twirling, and thrusting are performed on all needles to reach de qi, which is a sensation typically associated with needling including soreness, numbness, swelling, heaviness, and other feelings. This is considered to be an important component of the therapeutic effect of acupuncture.

"The placebo needles chosen for this study are flat-tipped needles without a tip, which could not be pierced into the skin. In the meanwhile, an external patch device will fix the needles, which are visually pierced into the skin. After the treatment, the acupuncturist will press the acupuncture point with a dry cotton ball so that the patient can feel the pulling out of the needle."
