transcranial magnetic stimulation therapy in neuropathic painful spinal cord injury patients

Conditions: Spinal Cord Injuries; Neuropathic Pain; Neurological Diseases or Conditions

Summary: the aim of our study is to investigate the effect of high-frequency repetitive transcranial magnetic stimulation(rtms) therapy applied to the dorsolateral pfc (dlpfc) area on neuropathic pain in patients with spinal cord injury. in this area, there are very few studies on the effectiveness of rtms treatment added to medical treatment in neuropathic pain. in addition, the number of studies comparing the effect of rtms therapy applied to the dlfpc area is very few.

spinal cord injury (sci) is associated with widespread disability due to its detrimental effects on various bodily functions. neuropathic pain is one of the most challenging complications after sci and can have a significant impact on daily life. there are supportive criteria for the diagnosis of neuropathic pain associated with sci: onset of pain within one year after sci, absence of primary association between pain with movement, inflammation or other local tissue damage, burning, tingling, pins and needles, throbbing pain, squeezing pain, detection of 1 or more of the pain descriptors such as freezing pain, allodynia or hyperalgesia within the pain distribution support neuropathic pain due to spinal cord injury. pharmacological and interventional treatments are often tried in the treatment of neuropathic pain, but their success is often limited. another option that has been used as an innovative approach in the treatment of neuropathic pain in recent years is pain regulation with rtms. as one of the non-invasive brain stimulation techniques, rtms is suggested to be useful in the treatment of central neuropathic pain. while most studies to date have mainly targeted the primary motor cortex (m1), which is contralateral to the pain side, fewer studies have reported analgesic effects after stimulation of other cortical areas such as the dorsolateral pfc (dlpfc). the analgesic mechanisms of rtms to the dlpfc are thought to be through the same mechanism as stimulation of the m1 motor cortex. the aim of our study; to investigate the effect of high frequency rtms applications on patients with sci on their neuropathic pain.
