About
Electromyogram is a current exam usually in neurological practices use for study peripheral nervous system. This is a semi-invasive examination causing pain. The aim of the study is to evaluate hypnosis practice in patients during an electromyogram. The investigator will evaluate pain with quantitative and qualitative evaluation in two groups with and without hypnosis in an open, quasi-randomised prospective therapeutic study in Pau hospital centre
Full description
Electromyogram is frequently use in neurological practices for neuropathies detection or others peripheral nervous system affection. There is two parts during this examination. The first is called sensory and motor nervous conduction study. It consists to apply cutaneous electrodes wich send electric current on arms and legs. The second is the detection with use needles in several muscles of the four limbs with muscle contraction. So, electromyogram is long (sometimes up to one hour) and painful assessment.
Hypnosis is an old not invasive easy practice using in some medical conditions like fibroscopy, anesthesia, surgery. The mechanisms are unclear but this is an effective practice particularly in pain management. Hypnosis in neurological examinations remains unusual. Only two studies report use of hypnosis during electromyogram. The first in 2009 is a randomised suty. On 26 patients, they study hypnosis impact on anxiety and pain. The conclusion is significant efficacity of hypnosis on pain during electromyogram with pain decrease of 31% compared with control group. The second is a French study with only poster. There was no significant difference between hypnosis group and control group during electromyogram for pain. But, there was significant difference for anxiety item. These two studies shown opposite results.
In this study, the sponsor propose to evaluate hypnosis during electromyogram. The main criteria is quantitative pain evaluation. A neurologist doctor will do electromyogram and specialized nurse will do hypnosis. This is a prospective open, quasi-randomised study with two groups of patients. One with hypnosis realised by expert practitioner during electromyogram realisation. One group without hypnosis. The investigator will note pain during examination with standardised quantitative (primary outcome) and qualitative (secondary outcome) evaluation. The investigator will use visual Analog Scale and Saint-Antoine Pain Questionary (QDSA) but also Beck Anxiety Inventory for psychological effect. The duration of study is one year in single centre. The Pau Hospital hope validate this practice of hypnosis in this indication and extend it to other hospital centers for improve the quality of patient care.
