Plain English summary of protocol
Background and study aims:
Fibromyalgia, also called fibromyalgia syndrome (FM), is a long-term condition that causes pain all over the body. Post-traumatic stress disorder (PTSD) is an anxiety disorder caused by very stressful, frightening or distressing events. PTSD often occurs in patients with FM.
Cognitive Behavioral Therapy (CBT) and Eye Movement Desensitization and Reprocessing (EMDR) are the treatments of choice for patients suffering from PTSD.
CBT is a type of therapy that aims to help you manage problems by changing how you think and act.
EMDR is a psychological treatment that's been found to reduce the symptoms of PTSD. It involves recalling the traumatic incident in detail while making eye movements, usually by following the movement of your therapist's finger.
The hypothesis of this study is that specific treatment for PTSD with EMDR based psychotherapy may generate a significant improvement in physical symptoms in patients with FM and PTSD
Who can participate?
Adults older than 18 years with a diagnosis of fibromyalgia and symptoms of PTSD.
What does the study involve?
Participants will be randomized to receive a psychotherapeutic treatment based on EMDR vs standing on the waiting list for 6 months.
What are the possible benefits and risks of participating?
Benefits could be obtained from a treatment that has demonstrated efficacy in treating PTSD. It is a safe therapy with no side effects.
Where is the study run from?
Hospital Universitario Infanta Cristina and Centro asistencial de la Sociedad Española de Medicina Psicosomática (Spain)

Intervention | Patients included were randomly assigned to treatment with EMDR through a structured protocol versus remaining on the waiting list for treatment which was offered and applied to this group once the follow-up period (6 months) ended. All the participants continued receiving their usual routine care from their own general practitioners and other healthcare providers. Randomization was performed using a computer-generated randomization list. Therapeutic intervention: The therapeutic intervention was carried out on an individual basis using a standardized protocol administered by a team of 20 psychologists and 5 physicians all of them trained in EMDR who were supervised through regular sessions by a senior psychologist with a long experience in EMDR. The EMDR intervention protocol was based on the procedure described by Shapiro (28) but including a modification specifically considered for the treatment of those patients who present high scores in dissociation. Patients in the treatment arm of the study received 22 individual 90-minute sessions, using this specific EMDR therapy protocol to treat past trauma-related symptoms. The intervention protocol was divided into an initial evaluation and five subsequent steps: - Initial evaluation: In this phase, the psychotherapist collects information regarding the patient’s biography, including an exhaustive lifeline and the collection of relevant information about the patient's history in order to develop a treatment plan. Some standardized scales and projective techniques are also used to complete the rigorous study of etiology and for the selection of the proper targets which will be treated with EMDR. This phase lasts for 6 days and the last one is for reading the report written by the psychologist in which the hypothesis about what variables could explain the actual suffering are exposed. It is also the moment for explaining how trauma works causing symptoms and why the intervention includes the use of EMDR. A brief explanation of the technique is also included. - Step 1. Preparation and widening of the window of tolerance. This is the main difference between Shapiro’s standard protocol and this specific one: the introduction of a phase inside the preparation one to work exclusively with desensitization in order to place the patient into an optimal situation for the intervention to be effective. This is the best way to reverse the effects of dissociation, which are, mainly, re-experimentation phobia and phobia between parts. This way of working also guarantees the necessary dual attention to reprocess and integrate traumatic experiences. The “lifeline” constructed in the evaluation is employed to work with it while using auditory bilateral stimulation. Additionally, in this phase, positive resources for emotional regulation are installed. The whole phase is carried out in 4 days. Step 2. Targeting the traumatic events from the past. There are only four days to work with the past so this phase begins with a session dedicated exclusively to select the targets which will be employed to go with EMDR. This session is crucial for the success of the treatment because it is necessary to find the nuclear events which would explain the major actual suffering and work with them. Total number of sessions: 5 Step 3. Based on working with the triggers of the present, (four days). The treatment with traumatic experiences must always consider working with past, present, and future in order to ensure good and consistent changes. So, in this phase, the most important triggers related to original trauma are targeted. Step 4. Based on working with anticipatory anxiety associated with the future. A specific future protocol is used here. Two targets are selected. They represent what the patient considers difficult to face even after all that has been worked during the past months. The cognition “I can do it” is searched and “installed” and as a result, this phase is really empowering and satisfactory. Two sessions are being held here. Step 5. Closure. The last session is to recapitulate. “Lifeline” is used again to guide the narrative. New explanations and meanings are searched and also new ways to face the requirements of everyday life. Supervision meetings were on an individual basis and organized at least in five moments during patient's treatment: One after session 3 of the evaluation, another one after finishing it to prepare the report. The third one after the session dedicated to find and measure the targets selected, the fourth during the work with the past, and the last one before the closing session |

Primary outcome measure | Data were collected at baseline and at the end of treatment or after 6 months of waiting list period. 1. Pain intensity assessed using: 1.1 Visual Analog Scale for pain (VAS pain) 1.2 Brief pain inventory 1.3 Fibromyalgia Impact Questionnaire (FIQ) 2. Fatigue was evaluated using the Multidimensional Fatigue Inventory (MFI-20) 3. Post Traumatic Stress Disorder symptoms were evaluated using the PCL-5 |
Secondary outcome measures | Data were collected at baseline and at the end of treatment or after 6 months of waiting list period. 1. Anxiety was evaluated using the Hamilton Anxiety Scale 2. Depression was evaluated by administering the Hamilton Rating Scale for Depression (HAM-D) |
