Background and study aims
Tinnitus is a term that describes any sound a person can hear from inside their body rather than from an outside source. There is currently no generally accepted explanation of how these phantom sounds come about, and also no effective treatment. Pilot studies have revealed that acupuncture may be used to treat tinnitus. Acupuncture points (acupoints) are locations on the body that are the focus of acupuncture treatment in traditional Chinese medicine. Acupoints located near to the area of the disease (local) and away from the area of the disease (distal) can be needled to treat the disease, and combining these acupoints can make the treatment more effective. The aim of this study is to assess the effects of acupuncture in subjective tinnitus patients.
Who can participate?
Patients aged 18-65 years who have had subjective tinnitus in one or both ears for at least 3 months.
What does the study involve?
Patients will be randomly allocated to one of four treatment groups. Group A will receive acupuncture at local acupoints in combination with distal acupoints. Group B will receive acupuncture at local acupoints in combination with distal non-acupoints (i.e., areas that are not acupoints). Group C will receive acupuncture at local non-acupoints in combination with distal acupoints. Group D will receive acupuncture at local non-acupoints in combination with distal non-acupoints. Participants will receive acupuncture for 4 weeks, at a frequency of two sessions per week. Acupuncture will be performed with sterile needles by a therapist with more than 6 years experience and an acupuncture license from the Ministry of Health of the Peoples Republic of China. No additional treatment will be allowed.
What are the possible benefits and risks of participating?
During the study, you will receive regular check-ups including hearing tests. Acupuncture may help improve your tinnitus but we cannot say this for certain until we have completed this and further research studies.
Where is the study run from?
Acupuncture clinic, Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University (China).
When is the study starting and how long is it expected to run for?
The study started in February 2012 and will run until December 2014.
Who is funding the study?
Beijing Health System (China).

Scientific title | Acupuncture at local and distant points for tinnitus: a randomized, blinded, controlled trial |
Study objectives | Evaluate the efficacy of acupuncture at local points in combination with distal points in tinnitus patients. |
Ethics approval(s) | Beijing Hospital of Traditional Chinese Medicine & Capital Medical University, 28/02/2012 |
Health condition(s) or problem(s) studied | Subjective tinnitus |
Intervention | This study is a randomized, single-blind, controlled study. Participants will receive acupuncture at local points in combination with distal points for 4 weeks. Time points are as follows: Visit 1: screening Visit 2: treatment initiation, participants will receive acupuncture for 4 weeks Visit 3: 4 weeks after first acupuncture, follow-up and treatment finish Visit 4: 8 weeks after first acupuncture, follow-up Patients who met the inclusion criteria and none of the exclusion criteria were randomized to one of four treatment groups: Group A will receive acupuncture at local acupoints in combination with distal acupoints. Group B will receive acupuncture at local acupoints in combination with distal non-acupoints. Group C will receive acupuncture at local non-acupoints in combination with distal acupoints. Group D will receive acupuncture at local non-acupoints in combination with distal non-acupoints. Treatment will be conducted over a period of 4 weeks, at a frequency of two sessions per week. |
Intervention type | Other |
Primary outcome measure | Subjective tinnitus loudness and annoyance perception was graded using the Visual Analogue Scale (VAS). The assessment was at baseline (before treatment initiation), 4 weeks after the first acupuncture and 8 weeks after the first acupuncture. |
Secondary outcome measures | 1. Change of tinnitus severity according to the tinnitus questionnaire of the Tinnitus Handicap Inventory (THI): 1.1. F: Functional subscale (11 factors) 1.2. E: Emotional subscale (9 factors) 1.3. C: Catastrophic subscale (5 factors) Each question of the THI can be answered by the patient with either often (2 points), sometimes (1 point) or never (0 points), with a maximum total score of 100 indicating most severe suffering from tinnitus. The assessment was at baseline (before treatment initiation), 4 weeks after the first acupuncture and 8 weeks after the first acupuncture. 2. Changes of tone and noise parameters of tinnitus, assessed by tinnitus matching (screening versus week 8) at 4 and 8 weeks after the first acupuncture, follow up. 3. Perceived Credibility of acupuncture was evaluated by The Treatment Credibility Scale (TCS) after a 4-week acupuncture session. It is a 5-item questionnaire ranging from 1 (not at all) to 5 (very confident); items were averaged to provide a single treatment credibility score, with high scores reflecting high treatment credibility. 4. To evaluate the adequacy of blinding, we asked participants to rate how certain they were that they had received traditional acupuncture or a new method of acupuncture on a 7-point scale (1 very sure, 7 very uncertain) after 4 weeks of treatment. Participants also reported adverse events they experienced, including discomfort or bruising at the sites of needle insertion, nausea, or feeling faint after each treatment. |
