UNLABELLED Acupuncture is a therapeutic treatment that is defined as the insertion of needles into the body at specific points (ie, acupoints). Advances in functional neuroimaging have made it possible to study brain responses to acupuncture; however, previous studies have mainly concentrated on acupoint specificity. We wanted to focus on the functional(More)
Measures of cue reactivity provide a means of studying and understanding addictive behavior. We wanted to examine the relationship between different cue reactivity measures, such as attentional bias and subjective craving, and functional brain responses toward smoking-related cues in smokers. We used eye-tracking measurements, a questionnaire for smoking(More)
The aim of this study was to compare behavioral and functional brain responses to the act of inserting needles into the body in two different contexts, treatment and stimulation, and to determine whether the behavioral and functional brain responses to a subsequent pain stimulus were also context dependent. Twenty-four participants were randomly divided(More)
OBJECTIVE This study investigated whether doctors' attire influences the perception of empathy in the patient-doctor relationship during a therapeutic encounter. METHODS A total number of 143 patients were divided into four groups when they were consulting a Traditional Korean Medicine doctor. Depending on the group, the same doctor was wearing four(More)
This study compared verum acupuncture (VA) and sham acupuncture (SA) stimulation by assessing autonomic and subjective responses. Autonomic responses such as skin conductance response (SCR) and heart rate (HR) were measured. Subjective pain ratings were collected and evaluated. A correlation analysis was performed for SCR and HR changes and subjective pain(More)
Background. The rubber hand illusion (RHI) is an experimental paradigm that manipulates important aspects of body self-awareness. Objectives. We were interested in whether modifying bodily self-awareness by manipulation of body ownership and visual expectations using the RHI would change the subjective perception of pain as well as the autonomic response to(More)
OBJECTIVES The patient's impression of the doctor is an important factor in a clinical consultation, and the doctor's attire also plays a great role in promoting trust and confidence in the patients. Previous studies have shown that a doctor in a white coat will appear more professional, confident, and trustworthy. The objective of this study was to(More)
Acupuncture stimulation increases local blood flow around the site of stimulation and induces signal changes in brain regions related to the body matrix. The rubber hand illusion (RHI) is an experimental paradigm that manipulates important aspects of bodily self-awareness. The present study aimed to investigate how modifications of body ownership using the(More)
OBJECTIVES A non-penetrating sham needle has been considered as a reliable control treatment in the field of acupuncture research. However, some concerns with regard to the credibility of sham needles have also been raised. We investigated whether there were differences in biomechanical properties and acupuncture sensation ratings in the process of needling(More)
Most of the time point-light figures are used for motion-recognition, which present motions by only displaying the moving joints of the actor. In this study we were interested in whether self-recognition of motion changes with different representations. First, we captured participants' motions and remapped them on a point-light figure and a male and female(More)
