Pain Catastrophizing, Pain Intensity And Perceived Injustice Do Not Predict Hrv In Acute Pain, Jacqueline Diulio Spt, Hailey Kettel Spt, Karin Steere Dpt, Phd

Physical Therapy Research Symposium

BACKGROUND: The nature of chronic pain conditions is well documented, with systemic biological, psychological and social factors interacting in an emergent fashion. Autonomic nervous system dysregulation, reflected as decreased heart rate variability (HRV), is suggested to be a biomarker of systemic dysfunction. Previous research has demonstrated correlations between numerous chronic pain disorders and diminished HRV.

PURPOSE: To determine the relationship between pain and HRV in the acute phase of pain, and to examine the predictive value of psychosocial variables on HRV. This study is meant to enhance our sense of how early in the pain experience decreased HRV may occur. …

The Relationship Of Catastrophization, Pain Intensity, And Heart Rate Variability In Acute Pain - A Pilot Study, Carolyn Barbee Spt, Elizabeth A. Waddell Spt, Karin Steere Dpt

Physical Therapy Research Symposium

Background: Reduction in heart rate variability (HRV) can strongly and independently predict adverse health outcomes.Chronic pain conditions are associated with reduced HRV, and HRV may be a biomarker for predicting chronic pain.

Purpose: While pain intensity and catastrophization are associated with chronic pain,the aim of this study is to investigate their relationship with HRV in individuals with acute pain.

Methods: Fourteen subjects from two facilities participated. Data from two participants was excluded. HRV was collected while seated as participants completed an iPad survey. Raw inter-beat interval (IBI) data was analyzed with Kubios software.

Results: Multiple regression analyses were …
