BACKGROUND In order to elucidate placebo and nocebo effects in visceral pain, we analyzed the effects of positive and negative expectations on rectal pain perception, rectal pain thresholds, state anxiety and cortisol responses in healthy women. METHODS Painful rectal distensions were delivered at baseline, following application of an inert substance(More)
OBJECTIVE Understanding the neural circuitry of placebo analgesia in the context of visceral pain is increasingly important given evidence of clinical benefit of placebo treatment in IBS. This functional MRI study addressed placebo analgesia in IBS, UC and healthy control (HC) volunteers. DESIGN Painful rectal distensions were delivered in N=17 patients(More)
To elucidate placebo and nocebo effects in visceral pain, we conducted a functional magnetic resonance imaging (fMRI) study to analyze effects of positive and negative treatment expectations in a rectal pain model. In 36 healthy volunteers, painful rectal distensions were delivered after intravenous application of an inert substance combined with either(More)
AIM We aimed to address the impact of Duchenne muscular dystrophy (DMD) on self-reported health-related quality of life (HRQOL) and depressive symptoms in different age groups of patients to discern a possible need for improved psychosocial support or counseling. METHODS In a German clinic for pediatric neurology, we performed a cross-sectional(More)
Regional changes in brain structure have been reported in patients with altered visceral sensitivity and chronic abdominal pain, such as in irritable bowel syndrome. It remains unknown whether structural brain changes are associated with visceral sensitivity. Therefore, we present the first study in healthy individuals to address whether interindividual(More)
Despite the clinical relevance of nocebo effects, few studies have addressed their underlying neural mechanisms in clinically-relevant pain models. We aimed to address the contribution of nocebo effects and their underlying neural circuitry to central pain amplification in visceral pain, as it may develop over repeated painful experiences due to negative(More)
BACKGROUND We explored sex differences in the neural mechanisms mediating placebo analgesia in an established visceral pain model involving painful rectal distensions in healthy volunteers. METHODS N = 15 men and N = 15 women underwent three consecutive functional magnetic resonance imaging sessions during which cued painful rectal distensions were(More)
OBJECTIVES The purpose of this study was to examine the relationship between exercise experiences (perceptions of competence, perceived exertion, acute affective responses to exercise) and affective attitudes toward exercise. This relationship was analyzed in a non-laboratory setting during a 13-weeks exercise program. MATERIALS AND METHODS 56 women and(More)
