Brief summary
The proposed study examines the differences in how the ANS responds to cervical adjustments in comparison to thoracic adjustments. This study is the continuation of a previous study titled Perceived stress and patterns of autonomic function: a protocol development study. Autonomic tests such as HRV, GSR, and the stress surveys will be the primary method of measurement. CareTaker and Biopac devices will provide continual data collection of ECG (for HRV analysis) and GSR throughout the exam and adjustment. Participant's subjective stress levels will be measured through the use of stress questionnaires including the National Stressful Events Survey Acute Stress Disorder Short Scale, the Hamilton Anxiety Rating Scale, and the Connor-Davidson Resilience Scale. The objective of the study is to determine if the location of a chiropractic adjustment will affect the autonomic nervous system in such a way that PNS or SNS activation increases or decreases after the adjustment. Further, the study will continue to examine how the chiropractic adjustment affects the subjective stress response.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Hamilton Anxiety Rating Scale | Through study completion, an average of 1 week | Measures the severity of anxiety symptoms |
| NSESSS | Through study completion, an average of 1 week | Measures PTSD symptoms in people 18 and up. |
| CD-RISC-25 | Through study completion, an average of 1 week | Measure of adaptability |
| Caretaker Heart Rate Variability | Through study completion, an average of 1 week | HRV allows for an understanding of Autonomic (parasympathetic) function, via measuring the interval of R peaks in QRS complexes. |
| Galvanic Skin Response | Through study completion, an average of 1 week | Galvanic Skin response gives a strong measure of Sympathetic response via electrical conductivity of perspiration. |
