Effects of interaction-visualizing feedback on heart rate variability and psychological outcomes during online shared eating
Prior studies suggest that sharing biosignals may enhance social presence and connectedness, and that online shared eating may influence heart rate variability (HRV), dyadic physiological covariation, loneliness, and mood. However, the effects of biosignal-sharing feedback during online commensality remain insufficiently examined. This preliminary randomized study investigated whether interaction-visualizing feedback—sharing participants’ physiol…
The impact of the prolonged Covid-19 pandemic on the practice of psychosomatic medicine in Japan
BACKGROUND: The prolonged COVID-19 pandemic has significantly affected the clinical care and the mental health of patients in psychosomatic medicine. Between late 2021 and early 2022, the Japanese Society of Psychosomatic Medicine (JSPM) and the Japanese Society of Psychosomatic Internal Medicine (JSPIM) conducted a nationwide physician survey to assess these effects. The survey identified difficulties in outpatient and inpatient care, increased …
Patients with postprandial distress syndrome experience problems with their interoceptive perceptual function to the gastric region, but their heartbeat perception is normal
BACKGROUND: Visceral hypersensitivity in functional dyspepsia can be localized or widespread, and there is no simple method of assessment. Measuring interoceptive accuracy at different sites provides an assessment of perceptual hypersensitivity to specific ecological phenomena. The purpose of this study was to characterize visceral hypersensitivity by comparing gastric sensory and cardiac perceptual tests in patients with postprandial distress sy…
Effects of eating together online on autonomic nervous system functions
BACKGROUND: Eating alone has been significantly associated with psychological distress. However, there is no research that evaluates the effects or relation of eating together online to autonomic nervous system functions. METHODS: This is a randomized, open-label, controlled, pilot study conducted among healthy volunteers. Participants were randomized into either an eating together online group or an eating-alone group. The effect of eating toget…
Awareness of comfort immediately after a relaxation therapy session affects future quality of life and autonomic function
High expectations regarding therapy are reported to have positive effects on future therapeutic course and related behavior. Some individuals are aware of feelings of comfort immediately after a relaxation therapy session. Heart rate variability biofeedback (HRV-BF) therapy using a relaxation technique called resonant breathing was administered to 44 family caregivers who felt burdened by their work caring for family members with cancer. We prosp…
Pain threshold reflects psychological traits in patients with chronic pain
BACKGROUND: Chronic pain enhances sensory sensitivity and induces the biased development of psychological traits such as depression and pain catastrophizing, leading to the formation of heterogeneous conditions. Fluctuations in the sensory-related thresholds of non-injured sites (with normal peripheral tissue) in patients with chronic pain are thought to be related to central sensitization. The objectives of this study were to analyze the associa…
The relationship between salivary amylase and the physical and psychological changes elicited by continuation of autogenic training in patients with functional somatic syndrome
BACKGROUND: The aim of this study was to clarify the changes in biological measures during autogenic training (AT) sessions and the relationship between these biological measures and the changes in physical and psychological measures induced by continuation of AT in patients with functional somatic syndrome (FSS). We used the salivary amylase (SAMY) level, skin temperature of the finger (TEMP), subjective symptom scores, and psychological charact…
Tolerable pain reduces gastric fundal accommodation and gastric motility in healthy subjects
BACKGROUND: Obstacles to pain management include patients' reluctance to inform healthcare provides about their pain, and differences in the pain management aims between patients and healthcare providers. The objective of this study was to evaluate whether tolerable pain influences gastric fundal accommodation and gastric motility in healthy subjects. METHODS: We undertook a crossover comparison study to evaluate gastric fundal accommodation and …
Relationship between Alexithymia and latent trigger points in the upper Trapezius
BACKGROUND: Latent trigger points (LTrPs) can be activated by future events, leading to pain. Few studies have reported LTrP risk factors. It has been suggested that alexithymia is associated with myofascial pain and diminished awareness of physical sensation. This study was designed to evaluate the relation between alexithymia and LTrPs found the upper trapezius of healthy individuals. METHODS: The correlation between LTrPs and alexithymia, and …
Self-controllable prodromal symptoms of syncope attributed to carotid sinus syndrome during the end stage of cancer
BACKGROUND: Carotid sinus syndrome (CSS) can cause prodromal symptoms of syncope such as dizziness and nausea. Patients with end-stage cancer lose self-efficacy associated with reduced activities of daily life (ADL). Herein, we report a case of end-stage cancer in which self-efficacy was enhanced as the patient gained self-control of prodromal symptoms of syncope. CASE PRESENTATION: A 70-year-old patient with end-stage esophageal cancer and enlar…
Links among emotional awareness, somatic awareness and autonomic homeostatic processing
Emotional awareness and somatic interoceptive awareness are essential processes for human psychosomatic health. A typical trait of lacking emotional awareness related to psychosomatic symptoms is alexithymia. In contrast, alexisomia refers to the trait of lacking somatic awareness. Links between emotional and somatic awareness and homeostatic processing are also significant for the psychosomatic health. The purpose of the present paper is to revi…
A family caregiver’s relaxation enhances the gastric motility function of the patient
BACKGROUND: The primary purpose of this study was to assess the effect of a caregiver's relaxation on the gastric motility function of the patient. The secondary purpose was to evaluate changes in the caregiver's willingness to perform self-care following feedback on the results of the primary purpose. METHODS: Subjects were 26 patients with a decreased level of consciousness who received gastrostomy tube feeding and their 26 family caregivers. W…
Psychological characteristics of Japanese patients with chronic pain assessed by the Rorschach test
BACKGROUND: The increasing number of patients with chronic pain in Japan has become a major issue in terms of the patient's quality of life, medical costs, and related social problems. Pain is a multi-dimensional experience with physiological, affective, cognitive, behavioral and social components, and recommended to be managed via a combination of bio-psycho-social aspects. However, a biomedical approach is still the dominant method of pain trea…
Biopsychosocial approaches to a patient with vomiting of 10 years' duration – a case of temporal lobe epilepsy
BACKGROUND: Vomiting is commonly encountered in clinical medicine. When organic gastrointestinal, metabolic, and brain diseases are ruled out, many cases are considered to be functional. We experienced an adult patient with epilepsy whose main symptom was vomiting. Biopsychosocial approaches were needed to control the symptoms. CASE PRESENTATION: A 26-year-old female with a 10-year history of persistent vomiting was found to have temporal lobe ep…
An Exploratory Study of Subgrouping of Patients With Functional Somatic Syndrome Based on the Psychophysiological Stress Response
Objective: To study the characteristics and subjective estimations of subgroups of patients with functional somatic syndrome (FSS). A characteristic in patients with FSS was reportedly hyporeactivity in the psychophysiological stress response (PSR). Methods: The PSR was measured in 59 FSS patients and 41 healthy controls. Autonomic lability scores (ALSs) of six psychophysiological measurements on PSR were calculated. Cluster analysis using the AL…
