NCT02903303

Brief Summary

This pilot study consists in testing the efficacy of hypnosis as an adjuvant treatment for patients suffering from chronic lumbar pain and for whom a facet block is indicated by a doctor in the Centre d'antalgie of CHUV (Centre Hospitalier Universitaire Vaudois), where this study will take place. 5 to 8 patients will be included in this study. The goals of this study are :

  • Assess the feasibility of such a protocol with more patients
  • Measure the number of patients necessary to obtain a significant result
  • Search for possible side effects of the combination of both treatments Every patient in this pilot study will undergo 4 hypnosis sessions within 2 weeks before the facet block. These sessions will be done with an hypnotherapist formed for this kind of treatment. Three times during this study, each patient will have a discussion with the co-investigator :¨
  • 1st discussion : just before the first hypnosis session
  • 2nd discussion : after the 4 hypnosis sessions and just before the facet block, approximately 3 to 4 weeks after the 1st discussion
  • 3rd discussion : 2 to 4 weeks after the facet block They will allow to obtain several data :
  • Pain assessment : intensity, localization, variability, characteristics, effects on daily life activities
  • Anxiety and depression assessment
  • Expectations assessment : about both treatments and their combination
  • Efficacy assessment : about both treatments for the patient
  • Questions about the perceptions of the treatments (prejudice, ...) et possible side effects. These data will then be analysed (quantitative and qualitative analysis, depending on the question type) to fulfill the objectives of the study. will include 5 to 8 people suffering from chronic lumbar pain. The procedure consists in two steps :
  • 4 hypnosis sessions as an adjuvant treatment for number 2
  • a facet block, which is the standard procedure in the Centre d'antalgie in CHUV.

Outcome Measures

Primary Outcomes (12)

  • Daily pain history

    During the first encounter (day 0), we will ask the patient since when he/she suffers from daily pain: * Daily pain in general since : \< 3 months ; 3-6 months ; 6-12 months ; 1-3 years ; 3-5 years ; 5-10 years ; 10-20 years ; \> 20 years * Daily lumbar pain since : \< 6 months ; 6-12 months ; 1-3 years ; \> 3 years

    1st encounter with the co-investigator (day 0)

  • Change in pain localization

    For this outcome, the patient is asked to say where is the daily pain and to precise if the pain concerns both sides. If there is more than one localization, the patient is asked to say which pain is the worst for him/her.

    1st, 2nd and 3rd encounters with the co-investigator (day 0, day 14-21, day 28-49)

  • Change in neuropathic characteristics of the lumbar pain

    Neuropathic characteristics (yes/no) : * burning * painful cold * electricity sensation * swarming * tingle * itching * numbness

    1st, 2nd and 3rd encounters with the co-investigator (day 0, day 14-21, day 28-49)

  • Change in lumbar pain intensity

    Intensity on a scale from 0 (no pain) to 10 (worst pain imaginable) : * Worst pain during the previous week * Lowest pain during the previous week * Average pain during the previous week

    1st, 2nd and 3rd encounters with the co-investigator (day 0, day 14-21, day 28-49)

  • Change in lumbar pain interferences

    For this outcome, we will ask the patient to tell us how much between 0 (no influence at all) and 10 (complete discomfort) the lumbar pain has on : A) General activity B) Mood C) Ability to walk D) Usual work E) Relationship with others F) Sleep G) Taste of living

    1st, 2nd and 3rd encounters with the co-investigator (day 0, day 14-21, day 28-49)

  • Change in Anxiety and Depression assessment

    In this pilot study, we will use the HADS scale (Hospital Anxiety and Depression Scale) to assess the level of anxiety and depression at the beginning of the study (day 0) and at the end of it (day 28-49). The items are the following (on a scale from 0 to 3, depending on the agreement to the sentence) : 1. I feel tense and angry 2. I am afraid, just like if something horrible was going to happen to me 3. I'm worried 4. I can sit quietly doing nothing and feel relaxed 5. I experience feelings of fear and feel my stomach tensed 6. I have ants in my pants and can't stay in place 7. I experience sudden feelings of panic 8. I feel the same pleasure to the same things as before 9. I easily laugh and see things in a good way 10. I am in a good mood 11. I feel like I work slowly 12. I don't take care about my appearance anymore 13. I'm looking forward to doing some things 14. I can enjoy a good book or a good TV/radio show
