NCT06171230

Brief Summary

The goal of this clinical trial is to investigate the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) therapy in reducing pain intensity in individuals with chronic painful diabetic neuropathy (PDN). The main questions it aims to answer are:

  1. 1.Does EMDR therapy significantly reduce pain intensity in individuals with chronic PDN?
  2. 2.What is the impact of EMDR therapy on secondary outcomes, specifically anxiety, sleep disturbances, and personalized pain-related limitations? Additionally, the study will explore the correlation between pain scores and symptoms of post-traumatic stress disorder (PTSD) in individuals with chronic PDN.

Outcome Measures

Primary Outcomes (1)

  • Pain intensity measured with the Numeric Rating Scale (NRS)

    The NRS is an 11-point numeric scale form 0 (no pain ) to 10 (worst pain)

    Pain intensity is assessed once daily in the evening for a maximum of 154 days (throughout all phases of the study (phase A, phase B, phase C, post-assessment phase, and follow-up phase.)

Secondary Outcomes (3)

  • Anxiety

    The anxiety level is assessed once daily in the evening for maximum of 154 days (throughout all phases of the study (phase A, phase B, phase C, post-assessment phase, and follow-up phase.)

  • Quality of your sleep

    Sleep problems are assessed once daily in the evening for a maximum of 154 days (throughout all phases of the study (phase A, phase B, phase C, post-assessment phase, and follow-up phase.)

  • Pain Disability Index (PDI) Limitations in daily activities

    The selected questions from the PDI are assessed once daily in the evening for a maximum of 154 days (throughout all phases of the study (phase A, phase B, phase C, post-assessment phase, and follow-up phase.)

Study Arms (1)

Eye Movement Desensitization and Reprocessing

EXPERIMENTAL

Participants will undergo six 90-minute EMDR sessions. The EMDR treatment concludes when the selected target images attain a Subjective Units of Disturbance (SUD) score of 0 or when three consecutive sessions show no further decrease in the SUD. Between the baseline phase (phase A) and the intervention phase (phase C), an attention control phase is introduced (phase B). This phase controls for the non-specific effects of the intervention, such as attention, treatment contact, and social support.

Other: Eye Movement Desensitization and ReprocessingOther: Attention control phase

Interventions

Using the LEC and PCL-5, emotionally charged images are selected at the onset of the EMDR intervention. Initially, events meeting the criteria for PTSD (A-criterion worthy events) are processed. Subsequently, pain-related experiences, including any distressing images, are addressed. If the emotional charge of the events diminishes (SUD=0) before the completion of the six EMDR sessions, the participant is categorized as an 'early completer,' and the post-assessment is conducted immediately. The duration of each EMDR session is 90 minutes.

Eye Movement Desensitization and Reprocessing

Prior to EMDR, there is a two-week attention control phase. During this phase, the participant is asked to daily record their activities, emotions, and thoughts when experiencing pain. This information is further explored and evaluated in two sessions lasting 45 minutes each, involving in-depth discussions with the participant.

Masking Details
In psychological research, it is not feasible to employ a 'blind' approach for both participants and EMDR therapists regarding the intervention. An independent research assistant, not otherwise involved in the study, oversees the completion of daily measurements and questionnaires. This ensures that EMDR therapists remain blind to the obtained data. An exception to this is the utilization of the results from the LEC and PCL-5, which are employed for case conceptualization. There will be no randomization of baseline length or initiation of the intervention, as seen in multiple baseline designs.
