Effects of State Trait Anxiety on Thorax, Diaphragm and Related Fascia.

A common pattern in nature is that dysfunctions manifest in more than one way and on more than one canvas. For example, climate change is predicted to manifest as rising sea levels, warmer sea temperatures, destruction of coral reefs, droughts, and crop failure. This same pattern is seen physiologically as well. Osteopathic physicians commonly see a pattern of somatic dysfunctions secondary to a visceral pathology. Some viscerosomatic pathologies have predictable manifestations, seen as Chapman points, small tender nodules within deep fascia. This present study follows a similar investigation but attempts to connect the visceral emotion of anxiety with somatic dysfunctions seen in fascia. A growing body of literature has connected emotions to the physical body and the mechanism involved in this interconnectedness. This present study will not focus on elucidating new mechanisms, rather it will focus on using osteopathic medicine as the tool to assess the physical manifestations of state-trait anxiety.

Individuals with mental disorders have increased adverse health behaviors, higher rates of chronic medical conditions, and increased mortality. Out of all of the mental disorders, anxiety has the highest prevalence. A substantial percentage of students within health science programs ie. nursing, medicine, and pharmacy, have reported elevated scores on self-reported anxiety questionnaires during their first year. A recent study by Hoying et al. 2020 reported that 30% of graduate students in health science programs had elevated scores on self-reported anxiety measures when entering their first year. This is pertinent to the present study as most of the participants will be recruited from Touro COM's first-year OMS-I class. Additionally, most studies have focused on the clinical form of anxiety, such as generalized anxiety disorder, but few have thoroughly addressed the subclinical forms of anxiety. The present study focuses on state and trait anxiety as defined by Spileberger. State anxiety is the proclivity of one to perceive a situation as threatening and transiently experience apprehension, tension, and dread. Trait anxiety is the stable inclination to experience state anxiety to varying external stimuli.

Despite extensive research focused on the treatment of clinical forms of anxiety, remission rates remain low, most notably less than 50% remission in patients with a generalized anxiety disorder (GAD). The standard of care involves both pharmacologic and psychological modalities, but nevertheless, the desired outcome of complete remission is not achieved. Therefore, there is a push in the scientific community to investigate anxiety through the lens of alternative and complementary medicines (CAM). While this study does not propose a novel treatment modality for state-trait anxiety, it does propose a new lens through which state-trait anxiety can be assessed and further examined. Using osteopathic manipulative medicine, the examiners uncover physical manifestations of anxiety that might have been overlooked when using standard-of-care modalities. This study will examine how anxiety manifests in one's bones, muscles, ligaments, and other objective measures.

This study will focus exclusively on the thoracic (respiratory) diaphragm and related fascia to fully examine osteopathic medicine as a tool for assessing state-trait anxiety. The investigators believe that maximal convergence between the mechanisms that govern fascia, anxiety, and their physical manifestations is located within the thoracic fascia and its relationship to the diaphragm. Previous studies have explored the relationship between one's breathing rate and their measures on anxiety questionnaires. It is widely accepted that anxiety affects one's breathing rate and quality. To examine the related fascia to the thoracic diaphragm, the study will include structures enveloped by Sibson's fascia and the endothoracic fascia. These structures include muscles such as the sternocleidomastoid, anterior/posterior/middle scalene, external intercostals, pectoralis minor, and the thoracic diaphragm itself. The related bones include ribs 1 -12, the sternum, the xiphoid process, the L1-L3 vertebral bodies, and the L1-L3 Intervertebral disk. The ligaments include the right and left crus. Additionally, it is pertinent to measure subjects' respiratory rate, Co2 retention, diaphragmatic excursion, and any somatic dysfunctions found in their thoracic inlet or related to Zinc's common compensatory patterns. Assessment with osteopathic manipulative medicine is a viable, cost-effective, and sustainable solution for assessing anxiety.

Using the osteopathic structural exam, this study aims to correlate subjective and objective findings of measures stated above with participants' responses on the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA) questionnaire. The STICSA inventory was chosen due to its superior ability to divide anxiety's cognitive and somatic aspects and distinguish state and trait anxiety. STICSA is also superior to the widely used State-Trait Anxiety Inventory in distinguishing between state-trait anxiety and depression.
