“…Lower regulatory frequency has also been found for the control of upper limb position in FM [ 27 ]. Similar to postural control in the present study, upper limb control deteriorated more in the patients with FM than in healthy subjects when visual information was removed [ 28 ]. In general, these findings corroborate the results of the present study suggesting deficits in somatosensory information or sensorimotor processing and a general slowness in the motor control system.…”

Lower regulatory frequency for postural control in patients with fibromyalgia and chronic fatigue syndrome

et al. 2018

As many similar symptoms are reported in fibromyalgia (FM) and chronic fatigue syndrome (CFS), underlying defcits may potentially also be similar. Postural disequilibrium reported in both conditions may thus be explained by similar deviations in postural control strategies. 75 females (25/group FM, CFS and control, age 19–49 years) performed 60 s of quiet standing on a force platform in each of three conditions: 1) firm surface with vision, 2) firm surface without vision and, 3) compliant surface with vision. Migration of center of pressure was decomposed into a slow and a fast component denoting postural sway and lateral forces controlling postural sway, analyzed in the time and frequency domains. Main effects of group for the antero-posterior (AP) and medio-lateral (ML) directions showed that patients displayed larger amplitudes (AP, p = 0.002; ML, p = 0.021) and lower frequencies (AP, p < 0.001; ML, p < 0.001) for the slow component, as well as for the fast component (amplitudes: AP, p = 0.010; ML, p = 0.001 and frequencies: AP, p = 0.001; ML, p = 0.029) compared to controls. Post hoc analyses showed no significant differences between patient groups. In conclusion, both the CFS- and the FM-group differed from the control group. Larger postural sway and insufficient control was found in patients compared to controls, with no significant differences between the two patient groups.

Interoceptive accuracy and bias in somatic symptom disorder, illness anxiety disorder, and functional syndromes: A systematic review and meta-analysis

2022

Somatic symptom disorder, illness anxiety disorder, and functional syndromes are characterized by burdensome preoccupation with somatic symptoms. Etiological models propose either increased interoceptive accuracy through hypervigilance to the body, or decreased and biased interoception through top-down predictions about sensory events. This systematic review and meta-analysis summarizes findings of 68 studies examining interoceptive accuracy and 8 studies examining response biases in clinical or non-clinical groups. Analyses yielded a medium population effect size for decreased interoceptive accuracy in functional syndromes, but no observable effect in somatic symptom disorder and illness anxiety disorder. The overall effect size was highly heterogeneous. Regarding response bias, there was a small significant effect in somatic symptom disorder and illness anxiety disorder. Our findings strengthen the notion of top-down factors that result in biased rather than accurate perception of body signals in somatic symptom disorder and illness anxiety disorder.

“…Empirical studies with findings that support this relationship investigated patient groups; for example, a negative association has been found between schizophrenia and somatosensory task performance (i.e., a proprioceptive deficit; Chang & Lenzenweger, ; Ritzler & Rosenbaum, ; Rosenbaum, Flenning, & Rosen, ), although null findings are also known (Leventhal, Schuck, Clemons, & Cox, ). A study investigating fibromyalgia reported no difference between patients and healthy controls in the proprioceptive accuracy of the knee (Ulus, Akyol, Tander, Bilgici, & Kuru, ), while other findings indicate that people with fibromyalgia rely more on visual feedback in the proprioceptive task of the upper arm (Bardal, Roeleveld, Ihlen, & Mork, ). A narrative review on knee osteoarthritis indicated impaired proprioceptive accuracy of the knee of the patients (Knoop et al, ).…”

Do body‐related sensations make feel us better? Subjective well‐being is associated only with the subjective aspect of interoception

2019

According to the proposition of several theoretical accounts, the perception of the bodily cues, interoceptive accuracy and interoceptive sensibility, has a significant positive impact on subjective well‐being. Others assume a negative association; however, empirical evidence is scarce. In this study, 142 young adults completed questionnaires assessing subjective well‐being, interoceptive sensibility, and subjective somatic symptoms and participated in measurements of proprioceptive accuracy (reproduction of the angle of the elbow joint), gastric sensitivity (water load test), and heartbeat tracking ability (Schandry task). Subjective well‐being showed weak to medium positive associations with interoceptive sensibility and weak negative associations with symptom reports. No associations with measures of interoceptive accuracy were found. Gastric sensitivity as opposed to heartbeat perception and proprioceptive accuracy moderated the association between interoceptive sensibility and well‐being. Thus, subjective well‐being is associated only with the self‐reported (perceived) aspect of interoception but not related to the sensory measures of interoceptive accuracy.
