Transcutaneous Electrical Acupoint Stimulation Combined With Exposure and Response Prevention in the Treatment of Patients With Obsessive-Compulsive Disorder: A Randomized Controlled Trial

4 de setembro de 2026 atualizado por: Jue CHEN, Shanghai Mental Health Center
Obsessive-compulsive disorder is a chronic and disabling mental disorder. Among them, 40-60% of obsessive-compulsive disorder patients do not respond to the current first-line drug treatment and/or psychological therapy. Traditional Chinese medicine treatment for obsessive-compulsive disorder has unique advantages. Acupuncture, as a traditional Chinese treatment technique, has been increasingly applied in the treatment of mental disorders such as insomnia, anxiety, and depression. Transcutaneous electrical acupoint stimulation (TEAS) can replace acupuncture. With equivalent effects, it can reduce pain and fear and is a non-invasive, safe, and time-saving physical intervention method. TEAS combined with exposure and response prevention therapy may have an additive effect in the treatment of obsessive-compulsive disorder. We will conduct a prospective randomized design to explore the integrated and optimized treatment plan of traditional Chinese and Western medicine for obsessive-compulsive disorder, improve the treatment efficiency, and reduce the proportion of chronic patients.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Experimental: ERP+TEAS treatment group
ERP+TEAS treatment group has 45 OCD patients.Each patient receives 16 sessions of ERP for 50 minutes. TEAS procedure is truly exciting and is carried out simultaneously with ERP. The targeted stimulation points are the bilateral Neiguan acupoints.
Comportamental: Exposure and Response Prevention
The first one is to establish the therapeutic relationship, mainly aimed at discussing the changes that the upcoming treatment can bring to the patient, helping the patient understand that their obsessive-compulsive symptoms are mainly due to their dysfunctional evaluation system and helping them understand the reasons for the gradual increase in their obsessive behaviors. Normalization of anxiety and the analysis of the pros and cons of anxiety lay the groundwork for the next exposure therapy. The therapist also needs to help the patient understand and accept the next TEAS synchronous ERP treatment. In the last treatment, the therapist should summarize the treatment process with the patient. In addition, the therapist needs to understand the patient's feedback on the treatment, consolidate the achieved treatment effects, and jointly discuss the prevention of recurrence with the patient.
Dispositivo: Active Transcutaneous Acupoint Electrical Stimulation
The acupoints stimulated are bilateral Neiguan points. The stimulation positioning is based on the "National Standard of the People's Republic of China · Acupoint Names and Locations" [GB/T 12346-2021] (2021). The stimulation frequency is 50Hz, and the pulse width can change with the frequency. The pulse amplitude (0-100 mA) is titrated to a "strong but comfortable" sensation level. The ERP treatment lasts for 8 weeks, twice a week, for a total of 16 sessions, all of which are TEAS synchronized with ERP treatment. Each treatment lasts for 50 minutes, with the first 20 minutes being the therapist's theoretical explanation, and the last 30 minutes being exposure practice. The TEAS stimulation starts simultaneously with the patient's exposure practice, and the stimulation duration is also 30 minutes.
Comparador Falso: ERP+sham-stimulation group
ERP+sham-stimulation group has 45 patients.Each patient receives 16 sessions of ERP for 50 minutes. TEAS intervention uses sham coils and is carried out simultaneously with ERP. The targeted stimulation points are the bilateral Neiguan acupoints.
Comportamental: Exposure and Response Prevention
The first one is to establish the therapeutic relationship, mainly aimed at discussing the changes that the upcoming treatment can bring to the patient, helping the patient understand that their obsessive-compulsive symptoms are mainly due to their dysfunctional evaluation system and helping them understand the reasons for the gradual increase in their obsessive behaviors. Normalization of anxiety and the analysis of the pros and cons of anxiety lay the groundwork for the next exposure therapy. The therapist also needs to help the patient understand and accept the next TEAS synchronous ERP treatment. In the last treatment, the therapist should summarize the treatment process with the patient. In addition, the therapist needs to understand the patient's feedback on the treatment, consolidate the achieved treatment effects, and jointly discuss the prevention of recurrence with the patient.
Dispositivo: Sham Transcutaneous Acupoint Electrical Stimulation
A transient placebo-tens simulation stimulation was adopted. A bonding electrode pad was placed 1 cm radially from the Neiguan acupoint. The stimulation intensity was adjusted to the minimum sensory threshold for 30 seconds, then gradually reduced over the next 15 seconds, making the stimulation active for a total of 45 seconds. This ensured that no current was transmitted to the electrode pad while maintaining the blinding condition.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
The reduction rate of the Yale Brown Depression Scale
Prazo: week 0（baseline）, week 8（post-intervention）, week12 (follow-up）
Calculation: Baseline YBCOS total score - Follow-up YBOCS total score / Baseline YBCOS total score.A deduction rate of 35% or higher is considered valid.
week 0（baseline）, week 8（post-intervention）, week12 (follow-up）

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
The reduction rate of the BDI-II
Prazo: week 0（baseline）, week 8（post-intervention）, week12（follow-up）

BDI-II：It consists of 21 items, used to assess the severity of each depressive symptom. Each item is divided into four levels ranging from 0 to 3. The total score of the scale is the sum of the scores of the 21 items. The BDI-II is one of the most widely used self-rating depression scales at present. The Chinese version was introduced by this research group and its reliability and validity were evaluated.

Calculation: Baseline BDI total score - Follow-up BDI total score / Baseline BDI total score. A reduction rate of 50% or higher is considered valid.
week 0（baseline）, week 8（post-intervention）, week12（follow-up）
The reduction rate of BAI
Prazo: Time Frame: week 0（baseline）, week 8（post-intervention）, week12（follow-up）

BAI：It consists of 21 items, each of which is divided into 0-3 levels, and is used for self-assessment of individual anxiety symptoms. The total score is the sum of the scores of each item, and the possible score range is 0 to 63 points. The higher the score, the more severe the anxiety symptoms. This scale has good internal consistency and test-retest reliability. Its Chinese version has similar reliability and validity to the original version.

Calculation: Baseline BAI total score - Follow-up BAI total score / Baseline BAI total score. A reduction rate of 50% or higher is considered valid.
Time Frame: week 0（baseline）, week 8（post-intervention）, week12（follow-up）
