Background: Opioids are effective for post-operative pain control but are no longer considered appropriate as the sole method for managing pain after surgery. Newer, multimodal approaches to pain control are increasingly being employed to decrease reliance on opioids, but patient-related outcomes are not consistently reported with these interventions.
Objective: This study evaluated the effect of implementing a new multimodal therapy order set, coupled with new patient education materials, on post-operative outcomes after complex shoulder surgery.
Objective: We aimed to relate clinical measures of disability in chronic cerebellar degeneration to structural whole-brain changes using voxel-based and surface-based morphometry (vbm and sbm). We were particularly interested in remote effects of cerebellar degeneration in the cerebral cortex.
Methods: We recruited 30 patients with cerebellar degeneration of different aetiologies (downbeat nystagmus syndrome, DBN n = 14, spinocerebellar ataxia, SCA n = 9, sporadic adult late-onset ataxia, SAOA n = 7).
Objective: Thalamic dysfunction in lesions or neurodegeneration may alter verticality perception and lead to postural imbalance and falls. The aim of the current study was to delineate the structural and functional connectivity network architecture of the vestibular representations in the thalamus by multimodal magnetic resonance imaging.
Methods: Seventy-four patients with acute unilateral isolated thalamic infarcts were studied prospectively with emphasis on the perception of verticality (tilts of the subjective visual vertical [SVV]).
Article Synopsis
- The study investigates how the brain processes self-motion signals by using whole-brain neuroimaging to identify the egomotion network in a large group of participants.
- Key brain areas involved in this network were pinpointed, including the cingulate sulcus, cerebellum, and temporo-parietal cortex, suggesting a connection with multisensory integration and spatial awareness.
- Findings indicate that specific connections, particularly between the cingulate sulcus and cerebellum, play a crucial role in perceiving egomotion, enhancing our understanding of how different sensory inputs combine for movement perception.
Evaluating the rare cases of cortical vertigo using disconnectome mapping.
Brain Struct Funct
December 2022
In rare cases, cortical infarcts lead to vertigo. We evaluated structural and functional disconnection in patients with acute vertigo due to unilateral ischemic cortical infarcts compared to infarcts without vertigo in a similar location with a focus on the connectivity of the vestibular cortex, i.e.
