Changes in posture can affect the resting length of the diaphragm, requiring alterations in the activity of both the abdominal muscles and the diaphragm to maintain stable ventilation. To determine the role of the vestibular system in regulating respiratory muscle discharges during postural changes, spontaneous diaphragm and rectus abdominis activity and modulation of the firing of these muscles during nose-up and ear-down tilt were compared before and after removal of labyrinthine inputs in awake cats. In vestibular-intact animals, nose-up and ear-down tilts from the prone position altered rectus abdominis firing, whereas the effects of body rotation on diaphragm activity were not statistically significant. After peripheral vestibular lesions, spontaneous diaphragm and rectus abdominis discharges increased significantly (by ∼170%), and augmentation of rectus abdominis activity during nose-up body rotation was diminished. However, spontaneous muscle activity and responses to tilt began to recover after a few days after the lesions, presumably because of plasticity in the central vestibular system. These data suggest that the vestibular system provides tonic inhibitory influences on rectus abdominis and the diaphragm and in addition contributes to eliciting increases in abdominal muscle activity during some changes in body orientation.

Inner body perception is a multisensory type of body perception that relates primarily to interoception, proprioception, and the vestibular system. Inner body perception may be disturbed in people with eating disorders (EDs), causing distortions or mismatches between how the body is perceived and how the body physically is. Despite this, there has been no systematic review that directly investigate inner body perception, and in particularly across anorexia and bulimia nervosa. To address these gaps, we conducted a systematic review using PRISMA guidelines. Twenty-six studies were included. Deficits in interoception and proprioception were observed across anorexia and bulimia nervosa, suggesting that alteration of inner body perception might be a crucial feature of eating disorders. From this perspective, inner body deficits in anorexia and bulimia nervosa represent a promising field that needs to be further explored, with the ultimate goal of developing new treatments that enhance the role of the inner experience as a therapeutic instrument.
