Emotional Freedom Technique (EFT) for Chronic Pain

Emotional freedom technique (EFT), an evidence-based stress reduction technique using cognitive therapy and stimulation of acupressure points, has been demonstrating efficacy in reducing pain and other conditions for chronic pain patients. 

Introduction

Current chronic pain affects 20-33% of the American adult population (more than 50 million adults) and represents a major health care crisis due its associated disabling physical and emotional problems (Gaskin & Richard, 2012), while resulting in healthcare costs of up to $635 billion a year (Dahlhamer et al., 2016; Johannes et al., 2010).

Poor-quality evidence for physical therapy; prescribed pain drugs and CBT ineffective

Evidence from randomised controlled trials reveals lack of rigour in the quality of evidence reported on the effectiveness of physical therapy to treat and improve chronic pain (van Middelkoop et al., 2011). In addition, although pharmacological treatments, specifically opioid prescriptions, have increased exponentially (Kenan et al., 2012) these drugs are often ineffective and incur a high risk for addiction and death (Abdel Shaheed et al., 2016). Similarly, meta-analytic evidence for use of cognitive behavioural therapy (CBT) to treat chronic pain as an adjunct to physical therapy demonstrates limited to no incremental benefit (Hajihasani et al., 2019).

Evidence-based EFT fills void, accepts bodily sensations to cope with pain

Due to this limited evidence and treatment void, several innovative mind-body interventions have emerged as potential treatments for chronic pain. Rationale for these psychotherapeutic approaches (provided at the body level) is indicated by the growing number of studies reporting acceptance of bodily sensations as an important mechanism in coping with pain and distress. One innovative non-pharmacological mind-body approach, Emotional Freedom Techniques (EFT), is an evidence-based brief intervention for anxiety, depression, phobias, and posttraumatic stress disorder.

EFT is stress reduction using cognitive therapy and stimulation of acupressure points

EFT is a manualised evidence-based stress reduction (for more on the neurobiology of stress, read our article Rethinking Stress) technique that utilises elements of cognitive therapy with physical stimulation of acupressure points (Church, 2013a). Efficacy has been established for depression, anxiety, phobias, and posttraumatic stress disorder (PTSD, Church 2013b). Moreover, changes in biochemistry, such as cortisol, blood pressure, immunity and an epigenetic potential to affect gene expression associated with PTSD symptomology, have been established (Bach et al., 2019; Church et al., 2012; Church et al., 2018; Stapleton et al., 2020). Systematic reviews and meta-analyses have indicated large effects for anxiety, depression and PTSD (Church et al., 2018b; Clond, 2016; Nelms & Castel, 2016; Sebastian & Nelms, 2017). EFT is suggested to affect amygdala activity, and the hippocampus (memory), both of which play a role in the decision process when one evaluates whether something is a threat. EFT has also been shown to lower cortisol levels (Church et al., 2012; Stapleton et al., 2020) and deactivate neural mechanisms that trigger undesirable emotions or behaviours. It is therefore logical that reducing this limbic system hyperarousal will allow for greater prefrontal cortex activity.

Process is SUDS rating and then tapping

The EFT process involves patients rating a concern (e.g., distressed feeling or discomfort) on a Subjective Unit of Distress Scale (SUDS; Wolpe, 1973) from zero to 10. A subjective measure of zero would represent an absence of distress and 10 would be the highest rating. Patients then vocalise their distress in a setup statement accompanied by an acceptance statement while physically tapping with two fingers on the side of the hand point (see Figure 1). For example, “Even though I have this worry about xxxx, I accept I feel this way”. The patient then manually stimulates (taps) the acupressure points in Figure 2, while stating a reminder phrase from the setup statement (usually the main concern e.g., “this worry”). The process is typically repeated until the patient’s SUDS rating is low.

Initial research and four-hour treatment show significant improvements

Initial research investigating EFT for chronic pain (Stapleton et al., 2015) offered a brief intensive 4-hour treatment program to participants in a persistent pain program.

Over the 4-hours there was a significant decrease in the severity (–12.04%, p = 0.044) and impact (–17.62%, p = 0.008) of participants’ pain, and a significant improvement in their overall psychological distress (–36.67%, p < 0.001). There was also a significant improvement in participants’ depression (–29.86%, p = 0.007), anxiety (–41.69%, p < 0.001), and stress (–38.48%, p = 0.001). A significant association was found between pain and psychological distress. A significant overall main effect of time was found at six-months’ follow-up.

Current Research

2020 research has now examined a 6-week EFT treatment program for chronic pain, delivered in two formats: self-paced (online) and facilitator-led (delivered live online due to COVID). Both versions had a waitlist condition. Participants (n=120 to date) were randomly allocated to one option or the other via computer randomisation.

Preliminary results for both EFT groups show positive results

Preliminary results for everyone who underwent the EFT intervention (both types of EFT delivery) indicate:

• A significant positive correlation between ACE (adverse childhood experiences score) and presence of PTSD symptoms
• A significant positive correlation between ACE and Quality of Life score, such that those participants with higher ACE scores had lower quality of life scores
• A significant number of participants who initially met the diagnosis of somatic symptom disorder, depression, anxiety, and panic disorder did not meet this after the EFT intervention
• A significant improvement occurred after the EFT treatment for all participants’ quality of life
• A significant reduction in pain severity occurred after EFT treatment for all participants
• There was no significant difference or change in PTSD symptoms or well-being after the EFT intervention because the participants did not suffer with PTSD symptoms to start with.

For the group who were awaiting EFT treatment (waitlist), there were no significant differences in any measures during this time before treatment. Their depression symptoms actually worsened significantly, and they also had a significant decline in well-being.

Differences between self-paced and facilitator-led EFT groups

We then examined the differences between the self-paced version of the program and the facilitator-led sessions. For the self-paced group:

• There was a significant decrease in the percentage of participants who met the diagnosis of somatic symptom disorder, depression, anxiety, and panic disorder after EFT intervention
• There was a significant improvement in quality of life after EFT treatment
• There was a significant reduction in pain severity after EFT treatment
• There was no significant different for PTSD symptoms or well-being for the self-paced group after EFT intervention because the participants did not suffer from PTSD symptoms to start with.

For the facilitator-led group, participants achieved the same results as the self-paced group in terms of not meeting diagnosis, and having a significant reduction in pain; however, there were no significant improvements in quality of life of PTSD symptoms and wellbeing.

It appeared the self-paced version achieved a slightly better outcome and indicated this mode of delivery may be suitable for those who cannot attend in-person sessions. A cautionary note here is that the sample sizes to date are different and the results will be re-analysed when the trial is complete. Six- and 12-month follow-up is occurring for those who have completed the trial, and a sub group will soon undergo fMRI scanning pre- and post-EFT treatment to examine neural changes after EFT treatment. This group will also be assessed for vagal tone/efficiency in partnership with Dr Stephen Porges and the Kinsey Institute Traumatic Stress Research Consortium, Indiana University (USA). This investigation will examine the impact of EFT on vagal tone for chronic pain patients.

Key takeaways

• EFT is an evidence-based stress-reduction technique using cognitive therapy and stimulation of acupressure points.
  
• Recent research using a self-paced EFT treatment, a facilitator-led EFT treatment, and control groups showed that a significant number of participants who initially met the diagnosis of somatic symptom disorder, depression, anxiety, and panic disorder did not meet this after the EFT intervention.
  
• The self-paced EFT group obtained slightly better outcomes than the facilitator-led EFT group.
  
• fMRI scanning will soon examine neural changes after EFT treatment
