Using Bilateral Stimulation (A Pre-existing Trauma Technique) After Eating to Reduce Anxiety in People Recovering From Eating Disorders
2026年5月21日 更新者：San Francisco State University
Bilateral Stimulation Versus Standard Care in the Treatment of Food Anxiety in Eating Disorder Patients: A Pilot Study
The goal of this clinical trial was to evaluate whether bilateral stimulation (BLS) could reduce anxiety and emotional distress after eating in people recovering from eating disorders in outpatient treatment with the primary researcher.
The main question it aimed to answer were:
Did bilateral stimulation reduce anxiety, depression, and/or eating disorder thoughts when used after eating a fear food?
Researchers compared participants who received standard treatment alone to those who received standard treatment plus bilateral stimulation after meals to determine whether BLS reduced emotional distress and negative thoughts related to eating.
Participants:
- Completed surveys assessing anxiety, depression, and eating disorder symptoms at the beginning and end of 4 consecutive sessions (4-12 weeks in total depending on the frequency of client appointments).
- Chose to participate in either a standard treatment group or an intervention group
Participants in the intervention group also:
- Ate 1 meal per week before or during session, including a "fear food" (defined as food avoided out of fear of what might happen, i.e., weight gain, vomiting, guilt/shame).
- Completed brief questionnaires about their thoughts and feelings after eating
- Participated in 3-5 minutes of bilateral stimulation (side-to-side tapping) guided by the researcher
- Reported on changes in their thoughts and emotions following the intervention
The intervention was delivered over 4 consecutive sessions alongside standard treatment.

无干预：Standard Outpatient Eating Disorder Treatment (ST)

|
实验性的：Standard Outpatient Eating Disorder Treatment plus Bilateral Stimulation (ST+BLS)
|
Participants in the intervention group (ST+BLS) completed 4 consecutive sessions.
In each session, participants ate a meal or snack, including a self-identified "fear food."
After eating, they completed a brief questionnaire assessing thoughts, emotions, and eating disorder urges, and identified preferred thoughts and feelings.
The researcher guided the BLS protocol and provided structured prompts, while participants actively performed the bilateral stimulation by engaging in alternating side-to-side tapping (e.g., shoulders, thighs, or feet), selecting the method most comfortable to them.
Participants completed three 20-second rounds of tapping while focusing sequentially on: (1) their experience of the meal, (2) desired thoughts, and (3) desired emotional states.
Brief discussions occurred between rounds.
After BLS, participants completed a follow-up questionnaire assessing changes in thoughts and feelings.
The researcher also completed a clinician-rated form.

Change From Pre- to Post-Bilateral Stimulation in Self-Reported Anxious Mood After Eating in the Standard Treatment Plus BLS Group Across 4 Sessions
大体时间：Across 4 consecutive sessions, completed over 4-12 weeks.
|
Anxious mood was assessed immediately before and after bilateral stimulation following eating episodes in the ST+BLS group.
Participants rated anxious mood on a researcher-developed 1-10 numeric rating scale, where 1 indicated "not at all anxious" and 10 indicated "extremely anxious."
Anxious mood was defined as worries, anticipation of the worst, fearful anticipation, or irritability.
Higher scores indicated greater anxious mood.

Across 4 consecutive sessions, completed over 4-12 weeks.

Change From Pre- to Post-Bilateral Stimulation in Self-Reported Depressed Mood After Eating in the Standard Treatment Plus BLS Group Across 4 Sessions
大体时间：Across 4 consecutive sessions, completed over 4-12 weeks.
|
Depressed mood was assessed immediately before and after bilateral stimulation following eating episodes in the ST+BLS group.
Participants rated depressed mood on a researcher-developed 1-10 numeric rating scale, where 1 indicated "not at all depressed" and 10 indicated "extremely depressed."
Depressed mood was defined as numb, dissociative, shut down, hopeless, lack of pleasure, or depressed.
Higher scores indicated greater depressed mood.

Across 4 consecutive sessions, completed over 4-12 weeks.

Change From Baseline to End of Treatment in State Anxiety as Assessed by the State-Trait Anxiety Inventory in Standard Treatment Versus Standard Treatment Plus BLS
大体时间：Baseline to end of treatment, 4-12 weeks.
