Summary

This randomized, double-blind, sham-controlled trial will evaluate whether low-frequency repetitive transcranial magnetic stimulation (rTMS) can improve in-hospital sleep quality in adult lung transplant recipients during early postoperative recovery.

A total of 152 participants with in-hospital sleep disturbance after first single- or double-lung transplantation 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 and will be delivered once daily for 10 sessions within 10-14 days.

The primary outcome is sleep quality measured using the Richards-Campbell Sleep Questionnaire during the nights following stimulation sessions 8, 9, and 10. The study will also evaluate wearable-device sleep measures, insomnia symptoms, pain, mood, cognitive and functional outcomes, safety, feasibility, and changes in brain activity measured by 64-channel electroencephalography.

  • Sleep Wake Disorders
  • Lung Transplantation

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. Treatment will be administered once daily for a total of 10 sessions completed within 10-14 days during the same hospitalization. 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 locked study device. The 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. Sham stimulation will be administered once daily for a total of 10 sessions within 10-14 days.
