“…The severity of the spatial neglect was quantified by a standard scale of behavioral neglect (ranging from 0 to 30) assessing both body and nonbody spaces. 24 The mean neglect score was 3.2Ϯ3.7. This apparently low score was attributable to the fact that, as expected 3 months after stroke onset, many patients showed no or mild signs of spatial neglect (especially those with a left stroke), whereas about 1/5 showed moderate to severe spatial neglect.…”

Background and Purpose-To analyze the postural behavior of standing stroke patients: (1) To differentiate between postural impairment attributable to the neurological condition (deficits attributable to the cerebral lesion) and postural impairment attributable to new mechanical constraints caused by body weight asymmetry; (2) To assess the involvement of each limb in the postural impairment; (3) To better understand which clinical deficits underlie the postural impairment. Methods-The posturographic characteristics of each limb in 41 stroke patients (first hemispheric stroke: 16 left, 25 right cerebral lesions) required to stand in their preferred posture were compared to those in 40 matched healthy individuals required to stand asymmetrically. Results-Compared to normal individuals in a similar asymmetrical posture, stroke patients were more unstable. The weight bearing asymmetry and the lateral postural instability were mainly related to spatial neglect. The paretic limb was unable to bring into play a normal longitudinal pattern of the center of pressure, which reflects an impaired stabilization control. Overall postural instability occurred when the strong limb was unable to compensate for the postural impairment of the paretic limb. Conclusions-The weight bearing asymmetry of standing stroke patients is not the primary cause of their postural imbalance, which is rather the consequence of impaired control of postural stabilization involving both limbs. Weight bearing asymmetry may not be the principle target of rehabilitation programs aiming at restoring standing balance after stroke. Instead it is suggested that more account should be taken of the compensatory role of the strong limb. (Stroke.

“…Currently, assessment of these related disorders often depends on behavioral observations and rating scales. Several measures of anosognosia have been developed (e.g., Azouvi, Olivier, et al, 2003;Bisiach, Vallar, Perani, Papagno, & Berti, 1986); these measures appear to be infrequently employed. Bedside or easily administered tasks assessing sustained attention and/or effort would be most useful.…”

“…It contains a lateralized attention scale that may be sensitive to a lateralized attentional impairment and is correlated with an ipsilesional minus contralesional score from a computerized task requiring responses to lateralized targets . Lastly, the Catherine Bergego Scale (Bergego et al, 1995), which rates neglect on a 4-point scale in 10 behavioral tasks (e.g., grooming, eating off a plate, maneuvering around furniture), may be more sensitive to pathological spatial bias than traditional paper-andpencil tasks and has been found to be reliable and valid (Azouvi, Olivier, et al, 2003), although it only assessed left-sided neglect.…”

Abstract& The spatial neglect syndrome, defined by asymmetric attention and action not attributed to primary motor or sensory dysfunction and accompanied by functional disability, is a major cause of post-stroke morbidity. In this review, we consider the challenges and obstacles facing scientific researches wishing to evaluate the mechanisms and effectiveness of rehabilitation interventions. Spatial neglect is a heterogeneous disorder, for which consensus research definitions are not currently available, and it is unclear which of the deficits associated with the syndrome causes subsequent disability. We review current opinion about methods of assessment, suggest a rational approach to selecting therapies which requires further study, and make systems-level and theoretical recommendations for building theory. We lastly review some creative questions for consideration in future research. &

“…Only exceptionally, the efficacy of a treatment is also assesses on daily life neglect behavior. A more frequent use of instruments like the Catherine Bergego Scale (Azouvi et al, 2003) or the functional evaluation of neglect with a Semistructured Scale (Zoccolotti and Judica, 1991) is needed to evaluate the impact of treatment on the daily life neglect behavior of patients. This also applies to the above mentioned issue of subtle neglect revealed by increasing attentional load.…”

Visuospatial neglect due to right hemisphere damage, usually a stroke, is a major cause of disability, impairing the ability to perform a whole range of everyday life activities. Conventional and long-established methods for the rehabilitation of neglect like visual scanning training, optokinetic stimulation, or limb activation training have produced positive results, with varying degrees of generalization to (un)trained tasks, lasting from several minutes up to various months after training. Nevertheless, some promising novel approaches to the remediation of left visuospatial neglect have emerged in the last decade.These new therapy methods can be broadly classified into four categories. First, non-invasive brain stimulation techniques by means of transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS), after a period of mainly diagnostic utilization, are increasingly applied as neurorehabilitative tools. Second, two classes of drugs, dopaminergic and noradrenergic, have been investigated for their potential effectiveness in rehabilitating neglect. Third, prism adaptation treatment has been shown to improve several neglect symptoms consistently, sometimes during longer periods of time. Finally, virtual reality technologies hold new opportunities for the development of effective training techniques for neglect. They provide realistic, rich, and highly controllable training environments. In this paper the degree of effectiveness and the evidence gathered to support the therapeutic claims of these new approaches is reviewed and discussed. The conclusion is that for all these approaches there still is insufficient unbiased evidence to support their effectiveness. Further neglect rehabilitation research should focus on the maintenance of therapy results over time, on a more functional evaluation of treatment effects, on the design and execution of true replication studies and on the exploration of optimal combinations of treatments.
