Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Objectives: This study aimed to evaluate the effect of high-frequency (10 Hz) repetitive transcranial magnetic stimulation (rTMS) on the left primary motor cortex (M1) for neuropathic pain in the lower extremities due to DPN.
Methods: In this randomized trial, 22 patients with DPN will randomly assign to the rTMS group (10 Hz stimulation, five sessions) or the sham group. A numeric rating scale (NRS) will use to measure pain intensity before treatment and after 1 day and 1 week of the treatment. Physical and mental health status will evaluate using the Short Form 36-Item Health Survey (SF-36), comprising two subscales (physical and mental component scores \[PCSs and MCSs\]), at 1-week post-treatment.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
rTMS group
Each patient will receive five consecutive sessions (Monday to Friday for 1 week).
Patients in the rTMS group will administer rTMS over the optimal scalp site at 10 Hz, with an intensity of 90% of the MT and a duration of 5 seconds, for a total of 20 trains separated by 55-second intertrain pauses (a total of 1,000 pulses). The coil will be placed tangentially to the scalp at an approximate angle of 45° tilted backward and laterally. Oral medication dosages of all patients will unchanged during the stimulation and follow-up periods.
repetitive transcranial magnetic stimulation
Repetitive transcranial magnetic stimulation (rTMS) is a safe, noninvasive, and effective therapeutic intervention that uses an electromagnetic coil applied to the scalp to produce a magnetic field. rTMS induces changes in cortical excitability at the stimulation site and transsynaptically at distant areas. Cortical excitability is increased by high-frequency (≥5 Hz) stimulation and is decreased by low-frequency (1 Hz) stimulation. The application of high-frequency unilateral rTMS to the motor cortex in patients is reported to have a potential to control various types of pain, such as neuropathic pain, fibromyalgia, and musculoskeletal origin pain (myofascial pain syndrome, shoulder pain, and lower back pain).
sham group
Patients in the sham group will administer sham stimulation using the same protocol, except that the angle of the coil is 90° (i.e., perpendicular, rather than tangential) to the skull. Oral medication dosages of all patients will unchanged during the stimulation and follow-up periods.
