BACKGROUND: Comparing cohorts with similar functional and motor status at admission to inpatient rehabilitation may delineate demographics or impairments associated with recovery from lateropulsion, also known as "pusher syndrome," after stroke based on lesion side. The aim of this case-control study was to determine how demographics and severity of stroke impairments at admission to inpatient rehabilitation distinguish patients who recover from lateropulsion from those who do not. METHODS: Patients with admission motor Functional Independence Measure (FIM) scores less than 31 and contralesional lower extremity Fugl-Meyer motor scores less than 19 out of 34 were included...

Since the first Broca publications issued from 1970s, lateralized functions in the human brain have urged the researchers to postulate hypothesis based in the right-left asymmetries and, according to some theories, the lateralization of the voluntary motor control could represent a solution to avoid redundant process optimizing space and time. Supported by this idea, the clinicians and researchers tend to concept that the chronic hemiplegic stroke patients learn to use predominantly the non-affected hemibody after stroke in which is more convenient to execute their daily life activities, modifying their natural preference in some cases...

To avoid detection at border crossings or airport customs, drug trafficking is increasingly performed by intra-corporeal concealment. Body packers may ingest packets of varying size and containing varying drugs (mostly cocaine, heroin and cannabis) mixed with other compounds, while body pushers will insert packets in the rectum or vaginal cavity. Body packing may lead to potential life-threatening complications with acute overdose syndromes after packet rupture and intestinal obstruction with possible ensuing bowel rupture being the most significant complications...

Herein, we summarize articles in the field of neuro-otology published in the Journal of Neurology over the last year. Topics included acute and chronic vertigo as well as auditory and ocular motor disorders. Characteristic lesion locations in Pusher syndrome are reported and the usefulness of bedside ocular motor tests in vertebrobasilar stroke is revisited. Probing the vestibular system and its value in predicting the outcome in vegetative state is discussed. Several articles address new diagnostic and therapeutic approaches in different disorders associated with chronic vestibular, auditory or gait deficits...

Pusher behavior (PB) is a disorder of postural control affecting patients with encephalic lesions. This study has aimed to identify the brain substrates that are critical for the occurrence of PB, to analyze the influence of the midline shift (MS) and hemorrhagic stroke volume (HSV) on the severity and prognosis of the PB. We identified 31 pusher patients of a neurological unit, mean age 67.4 ± 11.89, 61.3% male. Additional neurological and functional examinations were assessed. Neuroimaging workup included measurement of the MS, the HSV in patients with hemorrhagic stroke, the analysis of the vascular territory, etiology and side of the lesion...

OBJECTIVES: To analyze responsiveness to change of 2 outcome measures in the lateropulsion population after stroke. Lateropulsion describes an atypical balance problem after stroke where patients actively push themselves toward their paretic side. Secondary aims were to measure the incidence of lateropulsion and evaluate the site of the brain most commonly involved in lateropulsion. DESIGN: Stroke patients were screened for lateropulsion on admission to rehabilitation...

Unilateral stroke can lead to a disorder of postural balance that manifests as a pushing away toward the contralesional side. It is called "pusher syndrome" (PS). The aims of this study were first to assess the anatomical cortical regions that induce PS and second to clarify whether tilt of the subjective visual vertical (SVV)--a sign of vestibular otolith dysfunction--is associated with PS. Sixty-six patients with acute unilateral strokes (28 left-sided lesions, 38 right-sided lesions) were tested for PS, for tilts of the SVV, for hemineglect and for the anatomical lesion site by magnetic resonance imaging (MRI)-based voxelwise lesion-behavior mapping analysis...

Pusher behaviour (PB) reflects some misrepresentation of verticality. However, its neural mechanisms are still unclear. The aim of this pilot study is to assess the perception of the subjective visual vertical in patients with PB using an orientation discrimination task relying on a psychophysical forced-choice procedure. A sample of eight patients with post-stroke hemiplegia, three of whom with (PB+ group) and five without (PB- group) a clear PB, and 10 matched healthy subjects, was selected. All participants were assessed with an orientation discrimination task based on the objective Two-Alternatives Forced Choice (2AFC) procedure, in which observers are forced to report whether an oriented stimulus that was tilted off-vertical by a varying amount (but never vertical) was tilted clockwise or counterclockwise from vertical...

"Pusher syndrome" is classically described as a disorder of body orientation in the coronal plane. Although it mainly occurs in stroke patients, non-stroke causes have been described. Pusher behaviour is characterized by a tilt towards the contralesional paretic side and a resistance to external attempts to rectify. It may occur with or without hemispatial neglect, which in itself may be the cause of a usually ipsilesional shift of attention and body orientation in the axial plane. In this report we describe two patients with a marked disturbance of body orientation in the sagittal plane with imbalance, posterior tilt and an active resistance to forward pulling or pushing...

Brain damage may induce a dysfunction of upright body position termed "pusher syndrome". Patients with such disorder suffer from an alteration of their sense of body verticality. They experience their body as oriented upright when actually tilted nearly 20 degrees to the ipsilesional side. Pusher syndrome typically is associated with posterior thalamic stroke; less frequently with extra-thalamic lesions. This argued for a fundamental role of these structures in our control of upright body posture. Here we investigated whether such patients may show additional functional or metabolic abnormalities outside the areas of brain lesion...

Spatial neglect can be accompanied by a pusher syndrome (PS) which is characterized by a postural deviation towards the contralesional side. In this study, the representation of the body orientation in the horizontal plane was evaluated in neglect patients with and without PS. The participants had to align a luminous rod with the straight ahead direction, a method allowing the measure of both horizontal components of subjective straight ahead, i.e. lateral shift and yaw rotation. Eighteen patients with a lesion of the right hemisphere were compared with ten healthy participants...

Despite an increasing interest by researchers and clinicians, the pusher behaviour (PB) is still a poorly understood disorder, exhibited by some stroke patients, who push with their non-affected limbs towards the contralesional side and resist attempts at correction of their tilted posture. This review is aimed at critically summarizing findings on controversial issues regarding PB, namely correlation with neglect, neural correlates and underlying mechanisms. There is a growing agreement that PB reflects some misrepresentation of verticality...

Arthroscopic reconstruction of a rotator cuff tear is a demanding technique. Besides assessment and appraisal of the different types of tears, their mobilisation and, especially, secure refixation of the soft tissue are necessary if the operation is to be successful: suture anchors must be optimally placed, and suturing must be reliably achieved while the surgical field is viewed arthroscopically. A correct technique for arthroscopic knot tying after passage of the suture thread through the tendon is also essential for the holding strength of the sutures...
