简要总结
The purpose of this research is to find out if different types of anxiety impact the sensation of how sensitive various muscles are to the application of pressure. This information can help researchers and healthcare providers better understand how people feel pain differently based on emotional factors This study is designed to study people who can be expected to have normal pain sensation processing
详细描述
Pain-Pressure threshold (PPT) measurements have been used extensively in both research and clinical practice. Its use allows for somewhat more quantifiable pain assessment and has been shown useful for discriminative validity in ruling in or out various conditions. (3) Individuals with higher scores on standardized measures of anxiety have been shown to be predisposed to lower (more sensitized) PPTs. As a part of medicines developing understanding of psychosocial variables in the experience of pain this relationship is consistent with other research findings.
Trait anxiety is an individual's tendency to appraise situations as threatening, avoid anxiety provoking situations, and demonstrate high baseline physiological arousal. State anxiety is defined as "transient state of arousal subjectively experienced as anxiety This research aims to measure the individual relationships that trait anxiety and state anxiety may have on PPTs. These findings may allow clinicians to better understand one element of the biopsychosocial model of pain.
Pain-Pressure threshold(PPT) testing is an increasingly common and accessible technique used by clinicians to gauge for potential altered sensory processing. While anxiety has been shown to impact PPT, research has not been published which aims to differentiate the roles of trait and state anxiety in modification of sensory processing. While trait anxiety is thought to be a longer-term characteristic, state anxiety is thought to be more transient and influenced by circumstances. Trait anxiety is thought to influence state anxiety but does not account for all presented state anxiety.
Research examining the potential impact of trait and state anxiety as distinct yet related constructs may allow providers to better extrapolate a patient's baseline pressure sensitivity with less unexplained variability based on potential state changes.
Subjects will begin with the completion of the STAI-5 with subscales for trait and state anxiety.
