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 :
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 :¨
They will allow to obtain several data :
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 :
There will be no control group, so every patient will participate to the hypnosis sessions and undergo the facet block. All the procedure of the facet block (including contraindications and side effects) are not considered to be part of this study because all patients in this study would have had a facet block if they would not participate in it.
The only data that will be collected are questionnaires about several items (pain, anxiety, depression, ...). These questionnaires are filled with the patient at the beginning of the study (day 0), before the facet block (between day 14 and day 21) and 2-4 weeks after it (between day 28 and day 49). There are quantitative and qualitative questions.
