Summary

This study will evaluate the effects of non-invasive vagus nerve stimulation (nVNS) in adults with burn injuries. Burn patients may experience anxiety, poor sleep quality, pain, itching, and changes in autonomic nervous system function during recovery.

Participants will be randomly assigned to one of two groups. The intervention group will receive conventional physiotherapy plus nVNS, and the control group will receive conventional physiotherapy only. Both groups will receive treatment 5 days per week for a total of 10 sessions. nVNS will be applied through electrodes placed on the external ear for 20 minutes per session.

Anxiety, sleep quality, pain, itching, and autonomic function will be assessed before and after the treatment period. Autonomic function will be evaluated using heart rate variability measurements. The results will help determine whether nVNS may be a useful supportive method in the rehabilitation of burn patients.

Interventions

DEVICE

Non-Invasive Vagus Nerve Stimulation

Non-invasive vagus nerve stimulation will be applied using a Vagustim device. Electrodes will be placed on the tragus and the anterior and posterior surfaces of the concha of both ears. Stimulation will be applied continuously for 20 minutes per session with a biphasic asymmetric waveform, a pulse duration of 300 microseconds, and a frequency of 25 Hz. Stimulation intensity will be increased in 0.1 mA steps until the sensory threshold is reached. The procedure will be stopped if the participant feels unwell.

OTHER

Conventional Physiotherapy

Conventional physiotherapy will be planned according to each participant's needs and will be provided by a physiotherapist. The program may include strengthening exercises, stretching exercises, balance exercises, active and passive range-of-motion exercises, and interventions for edema. Sessions will be performed 5 days per week for a total of 10 sessions, with each session lasting approximately 45 minutes.
