Older adults (≥65 years) are particularly vulnerable to postoperative complications and their associated morbidities due to the biological aging process. Older adults comprise nearly half of surgical patients worldwide, and this number is expected to increase in the next 10-20 years as the aging population continues to grow. TKA is the most common procedure undergone by older adults, and the rate of TKA procedures is also expected to rise. Despite perioperative guidelines and protocols to prevent postoperative complications, the prevalence of postoperative complications following TKA is approximately 12%. Given these statistics, millions of older adults undergoing TKA may be at risk for postoperative complications and their associated morbidities in the coming decades. Therefore, additional interventions are needed to combat postoperative complications in this population.\n\nThe body's natural response to surgery, also known as the surgical stress response (SSR), contributes to postoperative complications through complex mechanisms involving the autonomic nervous system (ANS). Increased sympathetic nervous system (SNS) activity, or the body's fight-or-flight response, causes dysregulation in feedback systems that regulate the stress response, potentially leading to poorer outcomes. Interventions, such as breathwork, that induce the parasympathetic nervous system (PNS), or the body's rest-and-digest response, have been shown to balance the ANS, regulate stress biology, and improve outcomes. This study will examine the feasibility of adding a breathwork intervention (Box Breathing), compared to an attention control, to standard perioperative care for older adults undergoing TKA. This study will also examine the proof of concept that Box Breathing, compared to an attention control, may help regulate the SSR by assessing an objective measure of stress-related biology, diurnal cortisol rhythm, and gathering self-report information on pain, anxiety, depression, and quality of recovery following TKA.",[27,28,29,30,31,32,33,34,35,36,37,38,39,40],"Surgical Stress Response","Stress Physiological","Stress Physiology","Stress Psychological","Breathing Techniques","Breathing Exercises","Hypothalamic Pituitary Adrenal","Relaxation","Relaxation Therapy","Cortisol","Postoperative Pain","Postoperative Anxiety","Postoperative Depression","Quality of Recovery (QoR-15)",[27,42,43,44,32,31,45,37,38,39,46,47],"Total Knee Arthroplasty","Hypothalamic-Pituitary-Adrenal Axis","Breathwork","Postoperative Complications","Quality of Recovery","Diurnal Cortisol Rhythm","NOT_YET_RECRUITING","2026-03-06",{"date":51,"type":52},"2026-03-11","ACTUAL",{"date":54,"type":21},"2026-04-06",{"date":56,"type":21},"2026-09-30",{"name":58,"class":59},"University of Arizona","OTHER",{"id":61,"slug":62,"hasResults":11,"nctId":63,"briefTitle":64,"officialTitle":65,"acronym":66,"eligibilityCriteria":67,"healthyVolunteers":16,"sex":17,"minAge":68,"maxAge":4,"enrollmentInfo":69,"targetDuration":4,"studyType":71,"phases":4,"briefSummary":72,"conditions":73,"keywords":76,"overallStatus":80,"whyStopped":4,"lastUpdateSubmitDate":81,"lastUpdatePostDateStruct":82,"startDateStruct":84,"completionDateStruct":86,"leadSponsor":88,"locationsCount":90},"100494815","oklahoma-study-of-native-american-pain-risk-iii-stress-and-resilience-100494815","NCT05723081","Oklahoma Study of Native American Pain Risk III: Stress and Resilience","The Impact of Structural Racism and Discrimination (SRD) on Mechanisms of the Native American Pain Disparity","OK-SNAPIII","Inclusion Criteria:\n\n* Self-identify as Native American\u002FAmerican Indian\n\nExclusion Criteria:\n\n* \\\u003C18 years of age\n* Self-reported history of cardiovascular, neuroendocrine, musculoskeletal, or neurological disorders\n* Surrent chronic pain, defined as persistent, bothersome pain on more days than not for at least 3 months)\n* Self-reported current substance dependence\n* Sse of medication that could interfere with testing (e.g., recent use of analgesics, antidepressants, or anti-anxiety medications)\n* Inability to speak English\n* Current psychosis (assessed by Psychosis Screening Questionnaire)\n* Serious cognitive impairment (assessed by \\\u003C20 score on the Montreal Cognitive Assessment \\[MoCA\\])\n* Possible peripheral neuropathy (assessed by nerve conduction study)","18 Years",{"count":70,"type":21},220,"OBSERVATIONAL","The goal of this observational study is to learn about the relationship between environmental structural racism and discrimination and chronic pain risk in Native American adults.
