Effects of Non-Invasive Vagus Nerve Stimulation in Adolescent Burn Patients

4. Mai 2026 aktualisiert von: Sümeyye Akçay, Fenerbahce University

The Effects of Non-Invasive Vagus Nerve Stimulation on Anxiety, Sleep Quality, Pain, Itching, and Autonomic Functions in Burn Patients Aged 12-18

This study will evaluate the effects of non-invasive vagus nerve stimulation in adolescents aged 12 to 18 years who have burn injuries. The study will include patients who have completed the acute phase after burn injury and who have symptoms such as anxiety, sleep problems, pain, or itching.

Participants will be randomly assigned to one of two groups. One group will receive conventional physiotherapy together with non-invasive vagus nerve stimulation. The other group will receive only conventional physiotherapy. The treatment program will be applied 5 days per week for a total of 10 sessions.

The study will assess whether non-invasive vagus nerve stimulation improves anxiety, sleep quality, pain, itching, and autonomic nervous system function. These outcomes will be measured before and after the treatment program using clinical scales and heart rate variability measurements.

Detaillierte Beschreibung

Burn injuries may cause long-term physical and psychological symptoms in pediatric and adolescent patients, including pain, itching, sleep problems, anxiety, and changes in autonomic nervous system activity. These symptoms may negatively affect recovery and rehabilitation outcomes.

Non-invasive vagus nerve stimulation is a transcutaneous neuromodulation method that stimulates the auricular branch of the vagus nerve through electrodes placed on the external ear. This stimulation may influence autonomic nervous system regulation and may have potential effects on pain, sleep, anxiety, itching, and physiological recovery.

This study is designed as a randomized interventional study. Adolescents aged 12 to 18 years with burn injuries will be randomly assigned to an intervention group or a control group. The intervention group will receive non-invasive vagus nerve stimulation in addition to conventional physiotherapy. The control group will receive conventional physiotherapy only.

The non-invasive vagus nerve stimulation will be applied through electrodes placed on the tragus and concha regions of both ears. Stimulation will be delivered with a biphasic asymmetrical waveform, a pulse duration of 300 microseconds, and a frequency of 25 Hz. Each stimulation session will last 20 minutes. The stimulation intensity will be gradually increased in 0.1 mA steps until the participant's sensory threshold is reached. If the participant feels unwell during the stimulation, the procedure will be stopped.

Both groups will receive individualized conventional physiotherapy programs based on their clinical needs. These programs may include strengthening exercises, stretching exercises, balance exercises, active and passive range-of-motion exercises, and interventions for edema management. Conventional physiotherapy sessions will last approximately 45 minutes and will be applied 5 days per week for a total of 10 sessions.

Outcome assessments will be performed before the start of treatment and after completion of the 10-session treatment program. Anxiety will be assessed using the Beck Anxiety Inventory. Sleep-related symptoms will be assessed using the Adolescent Insomnia Scale. Pain will be assessed using the Visual Analog Scale. Itching severity will be assessed using the 12-Item Pruritus Severity Scale. Autonomic nervous system function will be evaluated using heart rate variability measurements recorded with a Polar H10 heart rate sensor and analyzed with Kubios HRV software.

The aim of the study is to determine whether non-invasive vagus nerve stimulation, when added to conventional physiotherapy, improves anxiety, sleep quality, pain, itching, and autonomic function in adolescents with burn injuries.
