Historia y Concepto 11 2. Los objetivos del presente trabajo fueron: En el primer estudio 12 pacientes fueron distribuidos aleatoriamente en dos grupos de tratamiento: No se obtuvieron diferencias funcionales en The Catherine Bergego Scale. En el tercer estudio 31 pacientes fueron aleatorizados en dos grupos de tratamiento: Los resultados indicaron cambios a nivel intragrupal en los cuatro grupos, sin embargo, no se obtuvieron diferencias intergrupales.
Ni el tiempo transcurrido entre el ictus y el inicio del tratamiento, ni el tipo de tratamiento recibido, parecieron ser variables que influyan en la mejora de estos pacientes. ABSTRACT Visuo-spatial neglect is a serious neurological disorder that affects two thirds of patients who have suffered a stroke in the middle or posterior cerebral artery of the right hemisphere.
It has also been associated with larger hospital stays and longer periods of rehabilitation. The functional effects of the treatment were assessed using the Catherine Bergego Scale. In the first study, 12 patients were randomized into two treatment groups: In both cases, the treatment consisted of a mean number of 15 sessions each lasting 1 4 hour. Significant between-group differences were observed when comparing the pre- and post-treatment scores for the Reading Task.
No differences were observed in either group in the Catherine Bergego Scale administered at baseline and at the final intervention. In the second study the structure and methodology was maintained from the previous study in order to check whether the effect obtained was maintained or increased with increasing sample size. A randomized clinical trial with 28 patients composed of two experimental groups was performed: In both cases, the treatment consisted of a mean number of 15 sessions each lasting 1 hour.
After treatment, both groups showed significant changes intragroup, but did not show differences between-group in the exploration protocol or the functional scale. The results obtained after applying these treatments indicated changes at intragroup level in the four groups analyzed.
However, no between-group differences were found. No differences in either group were observed in the Catherine Bergego Scale. Neither the time elapsed between the stroke and the 5 beginning of treatment nor the type of treatment received appear to be variables that influence the improvement of these patients. Refiere que la arteria cerebral posterior es la encargada de alimentar la corteza visual, mientras que la arteria cerebral media irriga la corteza somatosensorial y la auditiva.
Del mismo modo, las ramas dorsales de la arteria cerebral media, vascularizan con regiones de la corteza frontal y la parietal, ambas especializadas en el movimiento ocular.
Diversos autores han asociado la gravedad de la negligencia con lesiones en el FLS del hemisferio derecho Bartolomeo, Thiebaut de Schotten y Chica, ; Bartolomeo et al. Otros estudios asocian la presencia de negligencia, en las fases agudas post-ictus, con lesiones en el cuerpo calloso posterior Bozzali et al.
Este modelo se basa en tres postulados: Asimismo, observaron que cada hemisferio tiene preferencia por el espacio visual contralateral Egner et al. Los pasos que utilizaron fueron los siguientes: Se le pide al paciente que realice una tarea particular y se le confronta con los errores que ha cometido.
Se le pide que realice de nuevo el mismo ejercicio. Si no lo realiza el terapeuta le ayuda a implementar la estrategia. Finalmente, se les pide que intenten aplicar esta estrategia habitualmente en las situaciones de vida diaria.

Cognitive rehabilitation with right hemifield eye-patching for patients with sub-acute stroke and visuospatial neglect: A randomized controlled trial. Brain Injury; 29 4: To assess whether, following a right-hemisphere stroke, the combined administration of computer-based cognitive rehabilitation and right hemifield eye-patching in patients with visuo-spatial neglect is more effective than computer-based cognitive rehabilitation alone.
rehabilitación de la heminegligencia visuo
Twelve patients were randomized into two treatment groups: In both cases, the treatment consisted of a mean number of 15 sessions, each lasting heminegkigencia hour. The results obtained do not allow one to conclude that the combination treatment with cognitive rehabilitation and right hemifield eye-patching is more effective than cognitive rehabilitation alone.
Although partial improvement in the performance of neuropsychological tests was observed, this improvement is not present at functional level. This impairment manifests itself in different ways at a behavioural level: Although spontaneous post-stroke recovery can occur during the first weeks or months, time does not necessarily imply an improvement of VSN-associated symptoms .
One year after the 79 stroke, VSN patients may still demonstrate symptoms [7—9]. In a recent study, Nijboer et al. VSN has been associated with poor functional ability, increased dependence in daily life activities getting dressed, feeding, mobility ; and is also related to hemineggligencia hospital stages [7, 11—13].
In recent decades, various techniques to relieve, reduce or rehabilitate this impairment have, therefore, been proposed [14, 15]. VSN rehabilitation has been approached hemineyligencia different techniques and methods and also by different disciplines [16—18].
However, a fully effective treatment visuual yet to be identified . Furthermore, it should be noted that current techniques have shown hemineglogencia application in daily life activities.
Recently, the trend in VSN intervention has been characterized by non-cognitive approaches, ignoring spatial attention rehabilitation. Cognitive processes that could negatively influence VSN recovery have also not been taken into account.
Hemineglect: The Half of Everything
The results obtained show improved visual processing in the left half-field, increased attention in both half-fields, look intentionality and also in perception of contextual information . Some studies have found that this technique temporarily reduces the severity of VSN [30, 31].
They compared three groups of patients: All three groups performed the same rehabilitation programme , but the test 81 groups wore visual devices 12 hours a day for 3 months. The RHEP group was also found to look to the right for a longer time than the other groups. They recruited two groups: Results showed that the test group scored more highly in the test battery for the Behavioral Inattention Test; no significant differences were found in the FIM functional scale.
After analysing several techniques applied in VSN treatment, Saevarsson et al. Both teams have observed that more effects are obtained by combining methods than by using these techniques separately. They also suggest that the design of the intervention plays a major role, regardless of the number or intensity of therapeutic sessions.
This fact implies that the type of treatment used visuak not the only relevant factor and that both the design of the intervention and technique interaction can also be considered. The assumption is that patients who receive combined treatment will improve more than patients who only receive computer based cognitive treatment.
Patients with heminegligwncia following conditions were excluded from the study: The final sample consisted of 12 subjects six male and six female ; five of them had an ischaemic stroke and the rest a haemorrhagic stroke. The mean age at the time of the stroke was These 12 patients hemineegligencia randomized into two treatment groups: The treatment included a mean number of Visaul statistically significant baseline differences were observed between the two groups see Table I.
Materials All patients included neuropsychological in the exploration study were protocol for submitted assessing to a specific visuo-spatial attention. This protocol consisted of the following tests: The latter test was specifically designed for this study and consisted of reading three sentences on a horizontal A4 sheet.
The total number of words read by the patient was counted, with the highest score being The test was given either to the patient self-administered version or to a relative rater version. Procedures An information sheet was given to participants and relatives. Once the informed consent of the participants had been obtained, they were heminegligenciw a study number.
These numbers corresponded to the order in which the patients entered the study. A simple randomization procedure was performed according to a computer-generated random number table on a master list for one of two treatments. Application of such a simple hminegligencia procedure yielded seven patients in the ST group and five in the CT group. Fisual research assistant who generated the allocation scheme was not clinically involved in the study assessing or administering treatment to the patients.
Exercises included attention, memory heminegligencis executive function tasks. In all cases, adequate performance of the assigned tasks required visual processing of stimuli homogeneously distributed across the screen. RHEP was implemented by using non-prescription glasses especially made for the study. These glasses had a completely opaque right half-field for each eye. This group wore these glasses during all cognitive treatment sessions. Before starting treatment and also after, the neuropsychological exploration protocol described in the Materials section was administered.
Data analysis Data were described using absolute and relative rates, along with means and standard deviations, according to the type of variables. Two types of comparison were made.
The first one was a between-group comparison using a signed rank test to assess cognitive and functional alterations among pre- and post-treatment settings. A Mann-Whitney test was used in order to study the between-group effect.
Analyses were carried out via the SPSS v.
