Pain management is a priority axis of health insurance spending objectives and contributes to improving the quality of care.There are several types of pain: acute, chronic and induced. These are often found in the management of chronic wounds. The high prevalence of chronic wounds represents a major public health problem. Chronic wounds require long, painful and regular treatment. When dressing these wounds, pain management is essential. Indeed, it can generate healing delays. Usually, pharmacological methods are used to reduce the pain induced by care. But these methods can lead to undesirable effects. Thus, new non-pharmacological techniques are emerging.The investigators therefore wish to assess the effect of virtual reality on pain induced by care during the repair of dressings in the management of chronic wounds.
