Venous leg ulcer is the final stage of chronic venous disease and only develops due to advanced chronic venous insufficiency. The problems caused by venous disease are initially minor and often neglected, but can impact the quality of life of patients. The prevalence of leg ulcers is estimated at 1% of the general population and 3% to 5% of subjects over 65 years old. Its prevalence increases with age in both men and women. Managing chronic ulcers requires a certain number of care procedures, including debridement. The act of treatment by mechanical debridement is little relieved by the analgesics given beforehand, and can be painful, with risks of bleeding. Musicotherapy, particularly the U-shaped method, has shown its effectiveness in the treatment of pain and anxiety in several areas (geriatrics, intensive care, rheumatology, oncology, etc.). The standardized musicotherapy method of the U-shaped sequence was developed and initially evaluated by clinical studies coordinated by the INSERM unit U1061 (Pr. Jacques Touchon; Dr. Stéphane Guétin). Following the publication of numerous controlled, randomized studies presenting results on the effectiveness in the treatment of pain and anxiety, a digital application was developed in order to standardize the method. The Music Care health application is now a Class 1 Medical Device, with CE marking obtained. This U-shaped sequence is standardized and has been clinically validated, which makes Music Care a unique tool available for pain relief. No studies have been found in the literature regarding the use of music therapy during debridement care.
