About

Neuropathic pain is a common complication after spinal cord injury (SCI), which significantly affects the patient's quality of life and may be resistant to pharmacological treatment. In our study, we aimed to evaluate the efficacies of intermittent theta burst (iTBS) and high frequency (10 Hz) repetitive transcranial magnetic stimulation (rTMS) by comparing them with each other and with sham stimulation, in the treatment of neuropathic pain resistant to pharmacological treatment in patients with SCI.

Question 1: İs rTMS anda iTBS treatment, useful for pain severity and the effect of pain on daily functions, in the treatment of neuropathic pain in SCI Question 2: Are rTMS and iTBS treatments effective in depression in patients with neuropathic pain after spinal cord injury?

Full description

Pharmacological treatments may be insufficient to limit neuropathic pain. Therefore, research continues for safe and effective new treatments. Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation method that modulates the cortical excitability of the motor area to which it is applied. Theta Burst stimulation (TBS) is a new rTMS method consisting of stimulation sequences in a special pattern. It stands out with its ability to deliver high pulses in a short time and its high capacity to induce cortical plasticity. Intermittent TBS (iTBS) and high frequency rTMS facilitate excitability in the motor area where it is applied, and this effect is used in pain treatment. Pain modulation with these methods has been tried in some studies. Therefore, repetitive magnetic stimulation of the motor cortex by these two methods may be good options for the treatment of neuropathic pain resistant to pharmacological treatment in patients with SCI.

26 participants in 3 patient groups

10 Hz rTMS group

Active Comparator group

Description:

To the patients in the high frequency (10 Hz) rTMS (n:9) group, 110% resting motor threshold (rMT), 10 Hz frequency stimulation, 5-second stimulation, and then a total of 30 trains and 1500 pulses at 25-second intervals were applied for 15 minutes while targeting the lower extremity motor area.

Treatment:

Device: Magstim Rapid2 Magnetic Stimulator

iTBS group

Active Comparator group

Description:

To the patients in iTBS group (n:9), three bursts of stimulation at 50 Hz, repeated every 200 milliseconds, were delivered for 2 seconds every 10 seconds, totaling 600 stimuli at MT intensity, applied for a duration of 200 seconds.10 sessions was applied while targeting the lower extremity motor area.

Sham Group

Sham Comparator group

Description:

The patients in the sham group (n:8) were given sham stimulation with a sham coil for 10 sessions.
