Summary

This randomized, double-blind, sham-controlled trial will evaluate whether perioperative low-frequency repetitive transcranial magnetic stimulation (rTMS) can improve early postoperative in-hospital sleep quality in adults undergoing elective thoracoscopic lung resection for primary lung cancer.

A total of 220 participants with preoperative sleep impairment will be randomly assigned in a 1:1 ratio to active rTMS or matched sham stimulation. Active rTMS will target the left dorsolateral prefrontal cortex. Five stimulation sessions will be delivered within a 7-day perioperative window: two sessions before surgery, one session after extubation when the participant is clinically stable, and one session on each of postoperative days 1 and 2.

The primary outcome is sleep quality measured using the Richards-Campbell Sleep Questionnaire during the first three postoperative inpatient nights. The study will also evaluate wearable-device sleep measures, postoperative pain and analgesic use, recovery, safety, feasibility, and changes in brain activity measured by 64-channel electroencephalography.

  • Sleep Wake Disorders
  • Lung Neoplasms

Interventions

DEVICE

Active Low-Frequency Repetitive Transcranial Magnetic Stimulation

Active rTMS will be delivered over the left dorsolateral prefrontal cortex at the F3 position using a figure-of-eight coil. Stimulation parameters are 1 Hz, 100% of the resting motor threshold, and 1,800 pulses per session over approximately 30 minutes. Five sessions will be delivered within a 7-day perioperative window: preoperative day 2, preoperative day 1, 2-6 hours after extubation when clinically stable, postoperative day 1, and postoperative day 2. No more than one study stimulation session will be administered on the same calendar day.

DEVICE

Sham Repetitive Transcranial Magnetic Stimulation

Sham stimulation will be administered using a dedicated sham coil or validated active/sham masking module compatible with the study device. Target location, participant positioning, stimulation rhythm, sound, session duration, and interaction procedures will match active rTMS, but the sham procedure will not produce the intended therapeutic cortical stimulation. Five sham sessions will be delivered according to the same perioperative schedule as the active treatment.
