The Efficacy and Safety Study of Electro-acupuncture for Severe Chronic Functional Constipation
The main purpose of this study is to evaluate efficacy of electro-acupuncture for severe functional constipation compared with sham acupuncture, used as placebo; the secondary purpose is to evaluate the safety and post-treatment effect of electro-acupuncture.
Device: sham electro-acupuncture
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment

Primary Purpose: Treatment
|Official Title:||The Efficacy and Safety Study of Electro-acupuncture for Severe Chronic Functional Constipation - a Multi-center, Randomized Controlled Trial|
- The changed number of weekly average CSBM [ Time Frame: 1-8 weeks ] [ Designated as safety issue: No ]The changed number of weekly average CSBM (complete spontaneous bowel movement) during 8 weeks treatment, compared with baseline.
- The proportion of participants having three or more CSBMs on average per week [ Time Frame: 1-20 weeks ] [ Designated as safety issue: No ]The proportion of participants having three or more CSBMs on average per week during the 8-week treatment and 9-20th weeks.
- The changed number of weekly average CSBMs [ Time Frame: 9-20 weeks ] [ Designated as safety issue: No ]The changed number of weekly average CSBMs during 9-20th weeks, compared with baseline.
- The changed number of weekly average SBMs [ Time Frame: 1-8 weeks ] [ Designated as safety issue: No ]The changed number of weekly average SBMs (spontaneous bowel movement) during 8-week treatment, compared with baseline.
- Stool consistency [ Time Frame: 1-8 weeks ] [ Designated as safety issue: No ]Stool consistency (Bristol Stool Scale)
- degree of difficulty in defecation [ Time Frame: 1-8 weeks ] [ Designated as safety issue: No ]
The degree of straining during defecation: The severity of straining is graded using a 4-point ordinal scale.
0 = not at all
- = more straining than not
- = a great deal
- = an extreme amount, need finger manipulation to defecate
- PAC-QOL [ Time Frame: baseline and end of 8th weeks ] [ Designated as safety issue: No ]PAC-QOL（Patient-Assessment of Constipation Quality Of Life）
- incidence of adverse events [ Time Frame: 1-8 weeks ] [ Designated as safety issue: Yes ]
- Usage of medicine for constipation [ Time Frame: 1-20 weeks ] [ Designated as safety issue: No ]Any medicine for constipation used during the trial will be recorded, as well as the dosage and amount of every drug.

Every session lasts for 30 min per day. The participants are treated continuously for 8 weeks. During 8-week treatment the first 2 weeks, 5 sessions per week, and 3 sessions per week in the rest 6 weeks, 28 sessions for each patients in total.
Procedure: electro-acupuncture; Points:Tianshu (ST25) Fujie(SP14), Shangjuxu (ST37).Pierced the skin, needles are inserted 3 to 8 cm into bilateral ST25 and SP14 vertically until touching the parietal peritoneum.Electric stimulator is applied to bilateral ST25 and SP14 with dilatational wave, 15 Hz and electric current 0.1-1.0 mA.The participant's abdominal muscle twitching mildly is the appropriate dose. Bilateral ST37 are inserted 3 cm and then twirling lifting and thrusting for 3 times.Local sour and heavy feeling is appropriate dose. Steady small twirling lifting and thrusting 3 times in all. 30 min/per day/per session.During the 8 weeks treatment, the first 2 weeks,5 sessions per week, and 3 sessions per week in the rest 6 weeks,28 sessions for each patients in total.

Length of Treatment and the treatment sessions are the same as treatment group.
Device: sham electro-acupuncture
Procedure: sham electro-acupuncture; Points:Sham Tianshu(ST25),sham Fujie(SP14),sham Shangjuxu (ST37). Sham points location:2cm away from ST25,middle of Spleen and Stomach Channel;3cm from SP14,middle of Spleen and Stomach Channel; one point beside ST37,middle of Stomach and Gallbladder Channel; Performance: The needle is inserted by 1 to 1.5cm (the needle can be vertically fixed on the skin). No twirling lifting and thrusting. The electric stimulator is applied to bilateral sham ST25 and sham SP14 with dilatational wave,15 Hz and electric current 0.5 mA. The mental wire has been cut off with a same outlook as the treatment group. The electric stimulator is looked normal but with no current output. Length of Treatment and the treatment sessions are the same as treatment group.

Chronic functional constipation is a common disease. To date there has not specific therapy on chronic functional constipation. Systematic reviews indicate that acupuncture is probably effective for the disease, but the evidence is limited. Recently, we have finished a multi-center clinical trial of individualized deep electro-acupuncture (EA) for chronic functional constipation (n=460, Registration ID: NCT00508482) which preliminarily showed EA was effective.
This multi-center large-sample randomized controlled clinical trial of acupuncture for severe functional constipation is designed to confirm the efficacy and safety of EA.
This project is conducted by Chinese experts, supported by the Chinese Government. The research result is expected to provide high quality evidence of EA for chronic functional constipation.
