Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a single blinded randomized sham controlled clinical trial with two arms. 120 IBS patients will be recruited. The study will cooperate with Hong Kong Baptist University, and University of Toronto. After a 2-week run-in period, eligible subjects will be randomly assigned to one of two arms, acupuncture (AC) arm and sham acupuncture (SAC) arm. Each eligible subject will go through a 2-wk run-in-period, 6-wk treatment period and follow by a 6-wk of follow-up period. Five visits in total were scheduled for each subject in week 0, week 2, week 5, week 8 and week 14.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Intervention / Treatment

Intervention / Treatment

Experimental: Acupuncture group
Electro-acupuncture will be conducted for 2 sessions per week over 6 consecutive weeks. Disposable acupuncture needles (0.30 mm in diameter and 25-40 mm in length) are inserted at a depth of 10-30 mm obliquely into scalp acupuncture points (Baihui, Toulinqi) or straightly into body acupuncture points (Taichong, Zhangmen, Sanyinjiao, Zhongwan, Guanyuan, Tianshu, Zusanli). Electroacupuncture will be applied to the abdominal points at fast and dispersed waves through electric needle stimulator (ES-160 6-Channel Programmable Electro-acupuncture) for 30 min. The intensity is adjusted to a level at which patients feel comfortable.

Placebo Comparator: sham-acupuncture group
Sham-acupuncture will be conducted for 2 sessions per week over 6 consecutive weeks. Disposable acupuncture needles (0.30 mm in diameter and 25-40 mm in length) are inserted at the same way as in the acupuncture group but on sham-acupuncture points (Sham-Baihui, Sham-Toulinqi, Sham-Taichong, Sham-Zhangmen, Sham-Sanyinjiao, Sham-Zhongwan, Sham-Guanyuan, Sham-Tianshu, Sham-Zusanli). The sham points are non-acupuncture points nor located on meridians

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change on IBS-symptom severity scale
Time Frame: 0,8,14 weeks
Value from 0-500. The higher the score, the more severe the symptoms. When there is lowering of the sore between baseline and treatments, it indicates clinical improvement.
0,8,14 weeks
Change on Hamilton Depression Rating Scale (HAMD-17)
Time Frame: 0,8,14 weeks
Value from 0-57. Scoring 8-16: mild depression, 17-23: moderate depression, over 24: severe depression. When there is lowering of the sore between baseline and treatments, it indicates improvement on depressive symptoms.
0,8,14 weeks
Change on Clinical Global Impression-severity (CGI-S)
Time Frame: 0,8,14 weeks
Rating from 1-7, the higher rate indicates more severe of the mental problem. The subject is rated by researcher from his clinical experience. When there is lowering of the rating between baseline and treatments, it indicates improvement.
0,8,14 weeks
Change on Self-Rating Depression Scale (SDS)
Time Frame: 0,8,14 weeks
Value from 20-80. Scoring 50-69: depression, over 70: severe depression. When there is lowering of the sore between baseline and treatments, it indicates improvement.
0,8,14 weeks
Change on IBS Quality of Life (IBS-QoL)
Time Frame: 0,8,14 weeks
Value from 35-170. The higher the score, the lower the quality of life. When there is lowering of the sore between baseline and treatments, it indicates improvement.
0,8,14 weeks
