Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the clinical effectiveness of acupuncture treatment on residual insomnia in major depressive patients.

Condition or Disease	Intervention/Treatment	Phase
Insomnia Depression	Other: Acupuncture	N/A

Detailed Description

This is a randomized single-blinded controlled trial. Patients will be randomly assigned to one of the three groups. One is the traditional acupuncture treatment group, one is the non-traditional acupuncture treatment group and the other is an acupuncture-like placebo treatment. Patients will be put into groups and then compared. The chance of getting into each group is 1:1:1, i.e. equal chance.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Traditional Acupuncture Patients will be treated at bilateral Ear Shenmen, Sishencong EX-HN1, Anmian, and unilateral Yintang EX-HN3 and Baihui GV20. Acupuncture treatment will be performed by a registered Chinese medicine practitioner. "De qi"(an irradiating feeling considered to be indicative of effective needling) is achieved if possible. An electric-stimulator (CEFAR Acus II, Lund, Sweden) is connected to these needles to give an electric-stimulation in continuous wave, frequency of 4 Hz, 0.45 ms square wave pulses and constant current. Surgical tape or hair pin will be adhered to the needles.The needles will be left for 30 min and then removed. Acupuncture treatment will consist of three sessions per week for 3 consecutive weeks.	Other: Acupuncture Acupuncture at bilateral Ear Shenmen, Sishencong EX-HN1, Anmian, and unilateral Yintang EX-HN3 and Baihui GV20. The needles will be left for 30 min and then removed. Acupuncture treatment will consist of three sessions per week for 3 consecutive weeks. Other Names: Electroacupuncture
Active Comparator: Minimal Acupuncture Patients will be treated superficially at points away from classic acupoints. The points include bilateral "Deltoideus" [in the middle of the line insertion of Binao LI 14 and acromion], "Forearm" [1 inch laterally of the middle point between Shaohai HE3 and Shenmen HE7], "Upper arm" [1 inch laterally of Tianfu LU 3] and "Lower leg" [0.5 inch dorsally of Xuanzhong GB39]. "De qi" is avoided during needling. The treatment procedure, electric-stimulation, frequency, duration and number of treatment sessions will be the same for the Traditional Acupuncture group.	Other: Acupuncture Acupuncture at bilateral Ear Shenmen, Sishencong EX-HN1, Anmian, and unilateral Yintang EX-HN3 and Baihui GV20. The needles will be left for 30 min and then removed. Acupuncture treatment will consist of three sessions per week for 3 consecutive weeks. Other Names: Electroacupuncture
Placebo Comparator: Placebo Acupuncture Placebo needles designed by Streitberger (1998) will be used. The placebo needles are blunt needle that will not penetrate the skin during needle insertion. The handles of these placebo needles will slide over the needle when it is compressed, giving it the appearance of penetrating the skin. The placebo needles are inserted to the site 1 inch beside the acupoints in order to avoid the acupressure effect. The needles are held by a surgical tape or hair pin in hairy region to imitate the retention of needles. The needles are connected to an electric-stimulator with zero frequency and amplitude. The number, duration and frequency of the treatment sessions, and the intervention procedure will be the same for electro-acupuncture and placebo acupuncture.
