Neuromoduladors a mida permeten tractar el dolor neuropàtic complex de manera no invasiva i reversible

Chronic pain is a pain that persists beyond the average healing time for acute injuries, which is usually of three to six months, or the one that takes place in lifelong conditions. Chronic pain may also appear when there is not an obvious cause and the nervous system issues an alarm signal which is disproportionate or unnecessary in relation to the underlying stimulus. One of the most innovative techniques in the treatment of complex neuropathic pain, the most difficult to treat chronic pain which affects the central or peripheral nervous system, is the customised neuromodulator.

This is a non-invasive and reversible system that modulates the neuronal information created by the pain, whenever this can not be cured with drugs. “The device consists of a pacemaker that is implanted percutaneously. It sends controlled electrical impulses to some electrodes that are placed on the epidural space or the periphery nerves. Thus the pain signal is modulated and it reaches the brain with lower intensity”, explains Dr. Víctor Mayoral, head of section of the Chronic Pain Unit at Bellvitge University Hospital.

It is estimated that 20% of the population suffers from chronic pain, 17% in Spain, 4,5% suffer from severe pain and 9% suffer from pain daily. The most frequent pains are back, bones and joints pain. These have a very negative impact on people’s quality of life. Those affected by these types of chronic pain also suffer from insomnia, anxiety and depression. In addition to the impact on health, this pathology affects economy significantly through direct costs (increase in the dedication of healthcare staff, and consumption of medicines), and also through indirect costs related to the decrease in production because of worker absenteeism. The global cost of this pathology is estimated to reach roughly 2,5% total of the Spanish GDP.
