Dear Fellow Practitioners in Mental Health,
Although the therapeutic relationship is the main factor in our clients’ progress, you may be contacted by clients who are presenting with the impact of trauma for whom EMDR could be a powerful option; If you have a client whom you would like to talk through,  please contact meI also offer consultant supervision for practitioners working towards accreditation

You will know that the impact of childhood adversity is often at the root of the mental health problems that our clients present with 1. Repeated and chronic traumatic events in childhood can manifest in adulthood as Complex Post-traumatic Stress Disorder .

This has been increasingly recognised in the validation and publication of Complex Post-traumatic Stress Disorder [ CPTSD] as a diagnostic category in ICD 11 [2018]. In addition to symptoms of PTSD, clients with CPTSD will have experienced chronic, repeated & prolonged trauma and will have difficulties with emotional regulation, self-identity and relational capacity.2

Therefore, it can be challenging to distinguish borderline personality disorder from CPTSD, although there is an overlap, there are identifiable differences. Some clients who have had chronic, repeated and prolonged trauma will rather develop PTSD than CPTSD. It is possible for single incident trauma to result in CPTSD. CPTSD as might be expected, has a greater impact on functioning. High levels of comorbidity are expected in these clients, especially anxiety, agoraphobia , panic disorder ,  disordered eating , substance misuse and depression .

Women, because they are more likely to be subject to interpersonal violence are more likely to suffer from PTSD and CPTSD, and to experience the symptoms for longer than men. These diagnoses are associated with an increased risk of suicide. PTSD causes poor social and family relationships, absenteeism from work, lower income, education and occupational success.

CPTSD is a new diagnosis, and for this reason, treatment efficacy of E.M.D.R. for this diagnosis as opposed to PTSD has not been subject to randomised controlled trials.

The Assessment of PTSD and CPTSD.

It can be easy to miss or underestimate the impact of trauma in a client for the following reasons.

  • The comorbidity associated with the trauma may be the main presentation, so therapy may help with state change, rather than trait change.
  • The avoidance of retraumatisation and associated shame and guilt by talking about it in therapy.
  • The avoidance is very longstanding, and the client’s behaviour and relationships have adapted.
  • Dissociation is not always recognised. Dissociation can present in varied and subtle ways, for example, intermittent emotional shut down in relationships , feeling cut off from those people and places around you , subjective forgetfulness and poor concentration.
  • The trauma is embodied rather than in conscious awareness, so without considering physical sensations, will be missed.
  • Aspects of the therapeutic relationships trigger traumatic memories and /or the client does not feel safe enough to work on the trauma. 3

The following validated and widely used tools may help to fill gaps in the process of assessment and assess response to treatment ;

PCL- 5 is based on DSM- V [2013], completed by the client assesses the impact of a single event over the last one month.[U.S. Department Veterans Affairs .PTSD : National Center for PTSD. ] This questionnaire assesses symptoms of PTSD .

International Trauma Questionnaire based on ICD-11 2018 criteria ; completed by the client and assesses symptoms of PTSD before asking about the additional areas of emotional regulation , negative self concept , relational capacity and functioning which make up CPTSD 4, 5 . The clinician completed International Trauma Interview is in development.

Client's Stories

Sharon's Story

The following case study is fictitious and serve to illustrate real-life a problem and how E.M.D.R. can help;


Sharon is an experienced nurse redeployed to intensive care at short notice at the out break of Covid-19 . She initially coped with caring for a greater number of patients in PPE , communicating with distressed relatives by telephone and patients dying more often than normal. However , her work schedule and self isolation with her partner contributed to the break up of this relationship .

She noticed that she started to experience anxiety and panic going to work , her sleep deteriorated and she experienced nightmares during which close relatives died and she woke unable to breath . She had intrusive images of the faces of patients she had nursed occurring while awake . She would start to feel panicky if her father did not pick up the phone. She felt overwhelmed by feelings of anger if she saw members of the public breaking the Covid-19 rules. She felt tearful if she watched a sad film or followed the news. Sometimes she would dissociate as she was aware of gaps in recalling what she had done the day before . Sharon found that she was drinking 2-3 units of wine to help her to sleep every night . Eventually , she felt that she had to take a break from work .

At the age of 16 years she had been suddenly bereaved of her mother. As a family , they struggled with the consequences of this ; Sharon herself experienced low self esteem and feelings of guilt and responsibility regarding her loss .

With her EMDR practitioner she identified the beliefs about herself and associated physical feelings triggered by recent events , linking them to their source earlier in her life .


Sharon learnt to temporarily place her feelings of emotional distress and physical sensations into a container.
She learnt grounding techniques to reduce the tendency to dissociate.
She learnt to access a place in her mind where she felt calm [ safe place ] .
These techniques were installed using slow bilateral stimulation [ she chose butterfly taps ]
She was encouraged to attend to self-care ; regular exercise , periods of relaxation , regular diet and sleep hygiene .

Butterfly Taps

Butterfly taps are being used by Sharon in Phase 4  and can also be used to enhance resourcing

This is a self soothing technique originally developed for use in children.
Cross your hands over your chest .
Make  the shape of the butterfly with your hands.
Place the tips of your middle fingers on your collar bones and tap your fingers alternately at the speed suggested by the therapist.
Close your eyes or focus your gaze internally.
Take yourself to the safe place that you have developed and bring this together with the Breath deeply .
Notice your bodily feelings.
Continue tapping for 1-3 minutes .
Come out of your safe place and back in to the room. 

Example of performing the butterfly taps

Target Sequence

Desensitisation and Reprocessing


Once Sharon had reprocessed the significant events from the past she found that she felt less distressed by the impact of Covid-19 . At this point she was sleeping better, no longer had nightmares and was no longer depressed or anxious . There were still a couple of incidents which she found overwhelming which she went on to reprocess.She also reprocessed a recent incident when a member of the public not wearing a mask had bumped in to her in a shop.

Future Template ;

  • Using Bilateral Stimulation Sharon visualised herself at work , together with the changed belief she now holds about herself in that situation and associated physical feelings .
  • This prepared her mentally for a phased return to work which she completed successfully.

Client Reviews

  • "I had the pleasure of being treated by Dr. Lindon over a number of sessions, and the help I received was outstanding. From the very first session I began to notice a difference, and the improvements continued throughout. I was treated with warmth, dignity and compassion, and was made to feel completely comfortable and at-ease throughout. Dr. Lindon is a very genuine and caring lady. Highly recommended,  R. Smith."

  • "With Dr Lindon's help and guidance, I was able to develop strategies that have since helped me deal with stressful situations that I would have previously struggled with and to help me with negative beliefs, thoughts and feelings I've held about myself for several years."

  • "Completing EMDR therapy has been life changing and really insightful.  I learnt a lot about myself and have been astounded at the impact of reprocessing memories I wasn’t even aware were affecting me.  Through EMDR I have been able to make and sustain a number of changes that I did not think was possible.  Dr Lindon was kind, generous and empathetic and her approach really supported my progress.  I have recommended EMDR to so many people following my really positive experience."

  • "Frances is a very skilled therapist who supported me to overcome some very complex trauma. She made me feel safe and able to explore my difficulties in a very containing way. I will be forever grateful for my therapy with her and would fully recommend her services."

  • Callum says "I have found EMDR therapy to be life-changing, I was initially sceptical of the process but I cannot argue against the results which have been immensely positive for me. I found Frances to be very empathetic and felt listened to throughout the process. This is, without doubt, the best thing I have ever done and my only regret is not doing it sooner."
