简要总结
The purpose of this study is to determine if nVNS will decrease autonomic symptom intensity (COMPASS-31 and Child Functional Disability Inventory) in adolescent patients with postural orthostatic tachycardia syndrome (POTS) in comparison to standard recovery STEPS management.
详细描述
Project purpose: The investigators will study the use of non invasive vagal nerve stimulation in newly diagnosed adolescent patients with POTS to see if symptom management improves over 2 months. Surveys will include COMPASS-31. Child Functional Disability Inventory, and PHQ-9. Patient logs will evaluate headache frequency, exercise duration and VNS use.
Research objectives: The investigators hypothesize that:
Primary Aim 1. Use of noninvasive vagal nerve stimulation will decrease autonomic symptom intensity compared to control group.
Primary Aim 2. Use of noninvasive vagal nerve stimulator will improve child function.
Primary Aim 3. Heart rate elevation measured by head up tilt table test will decrease in the treatment group compared to the control group.

结局指标
主要结局
The Change in Composite Autonomic Symptom Score (COMPASS-31)
时间窗: Baseline; 8 Weeks
The change in COMPASS-31 score from baseline to 8 weeks. COMPASS-31 measures autonomic dysfunction in patients with neurodegenerative diseases. It consists of 31 patient-reported questions assessing various symptoms, including orthostatic intolerance, vasomotor symptoms, and gastrointestinal issues. Total scores range from 0 to 100, with higher scores indicating more severe symptoms.
The Change in Child Functional Disability Inventory Scores
时间窗: Baseline; 8 Weeks
The change in Child Functional Disability Inventory scores from baseline to eight weeks. The Child Functional Disability Inventory assesses the physical and psychosocial functioning of children due to their physical health. It consists of 15 items that measure activity limitations due to being sick or not feeling well. The total scores range from 0 to 60 with higher scores indicating greater perceived functional disability.
The Change in Heart Rate (Beats Per Minute) in Head up Tilt Table Tests
时间窗: Baseline; 8 Weeks
The change in heart rate, measured in beats per minute (BPM), in the head up tilt table test (HUTT) from baseline to 8 weeks.
次要结局
- Change in the Number of Headaches Experienced by Adolescent Patients With POTS(Baseline; 8 Weeks)
- Change in Exercise Duration (Minutes) in Adolescent Patients With POTS(Baseline; 8 Weeks)
- Change in PHQ-9 Scores in Adolescent Patients With POTS(Baseline; 8 Weeks)
