Communicative Effectiveness

The functional communication of a group of 28 South African stroke patients was examined using the Communicative Effectiveness Index (CETI). It was translated into Afrikaans, Sotho and Zulu and administered to the significant others of 22 aphasic patients with left hemisphere damage and 6 patients with right hemisphere damage. Results were related to the results of standardised language testing and to case history factors such as cultural factors and time since onset. The CETI was readministered in the case of eight of the aphasic subjects after a mean period of six months in order to assess its sensitivity to recovery. Results showed that the CETI seems applicable across different language groups, that it is sensitive to change across time as well as sensitive to the communication disorders resulting from both right and left hemisphere damage. Further it appears to correlate well with overall level of severity. It does not appear differentiate patients in terms of time since onset. Its potential use as a relatively culture free assessment tool in the South African context is discussed.

Background and Purpose: Poststroke aphasia has a major impact on peoples’ quality of life. Speech and language therapy interventions work, especially in high doses, but these doses are rarely achieved outside of research studies. Intensive Comprehensive Aphasia Programs (ICAPs) are an option to deliver high doses of therapy to people with aphasia over a short period of time. Methods: Forty-six people with aphasia in the chronic stage poststroke completed the ICAP over a 3-week period, attending for 15 days and averaging 6 hours of therapy per day. Outcome measures included the Comprehensive Aphasia Test, an impairment-based test of the 4 main domains of language (speaking, writing, auditory comprehension, and reading) which was measured at 3 time points (baseline, immediately posttreatment at 3 weeks and follow-up at 12-week post-ICAP); and, the Communicative Effectiveness Index, a carer-reported measure of functional communication skills collected at baseline and 12 weeks. Results: A 2-way repeated measures multivariate ANOVA was conducted. We found a significant domain-by-time interaction, F =12.7, P <0.0005, indicating that the ICAP improved people with aphasia’s language scores across all 4 domains, with the largest gains in speaking (Cohen’s d =1.3). All gains were maintained or significantly improved further at 12-week post-ICAP. Importantly, patients’ functional communication, as indexed by changes on the Communicative Effectiveness Index, also significantly improved at 12-week post-ICAP, t =5.4, P <0.0005, also with a large effect size (Cohen’s d =0.9). Conclusions: People with aphasia who participated in the Queen Square ICAP made large and clinically meaningful gains on both impairment-based and functional measures of language. Gains were sustained and in some cases improved further over the subsequent 12 weeks.

Functional impairment of the upper limb (UL) after stroke is a great problem. Finding methods that can improve UL function after stroke is a major concern to all medical service providers. This study was intended to compare the effect of upper limb task specific training (TST) on brain excitability of the affected hemisphere and motor function improvements in patients with left and right stroke. Forty male patients with mild impairment of UL functions were divided into two equal groups; G1 consisted of patients with left hemisphere affection (right side stroke) while G2 consisted of patients with right hemisphere affection (left side stroke). All patients received TST for the affected UL for one hour, three sessions per week for six consecutive weeks. Evaluation was performed twice, pre-, and post-treatment. Outcome measures used were Wolf Motor Function Test (WMFT) and Box and Block Test (BBT) as measures of UL motor function and Quantitative Electroencephalogram (QEEG) of motor and sensory areas of the affected hemisphere as a measure of brain reorganization post-stroke. Both groups showed improvement in motor function of the affected UL measured by WMFT and BBT with reported significant difference between them. G1 showed greater improvement in motor function of the affected UL post-treatment compared to G2. Additionally, there was a significant increase in peak frequency of motor and sensory areas with higher and significant excitability in G1 only. These findings imply that brain reorganization in the left hemisphere responded more to TST compared to the right hemisphere. Based on findings of the current study, we can recommend adding TST to the physical therapy program in stroke patients with left hemisphere lesions.

ABSTRACT OBJECTIVE In 90% of normal subjects, the left hemisphere is dominant for language function. We investigated whether congenital lesions of the left perisylvian regions altered cortical language representation in right-handed individuals. METHODS Using functional magnetic resonance imaging, we studied language hemispheric dominance in five right-handed adult patients with congenitally acquired arteriovenous malformations (AVMs) originating from left hemispheric cortical language regions. The AVMs had not caused neurological symptoms during early development, but patients presented as adults with migraine, seizure, or minor hemorrhage. Results obtained from the AVM patients were contrasted to those from right-handed brain-injured stroke patients recovering from aphasia and to those from right-handed normal subjects. RESULTS During silent picture naming and verb generation tasks, cortical language networks lateralized primarily to the right hemisphere in the AVM group, compared with the left hemisphere in the normal group. This right hemisphere-shifted language network in the AVM group exceeded the shifts toward right hemispheric dominance found in the stroke group. CONCLUSION Patients with AVMs affecting the left perisylvian regions recruited the right hemisphere into language processing networks during early development, presumably in response to congenitally aberrant circulation. This early right hemisphere recruitment in the AVM patients exceeded the similar process in the brains of stroke patients whose left cortical language networks were damaged in adulthood. Our data provide evidence of effective plasticity in the developing human brain compared with the mature brain response to injury. Knowledge of cortical language representation should assist presurgical planning in patients with developmental anomalies affecting apparently language-dominant brain regions.

This study aims to identify WAIS-IV profiles in unilateral ischemic stroke patients in rehabilitation (n = 107) compared to matched controls, to determine if patients demonstrate lateralized cognitive impairment, and to investigate whether aphasia has an additional effect on language and working memory subtests. Analyses revealed impairment in performance of stroke patients relative to controls, while effect of left-hemisphere stroke were large on subtests with language and processing speed demands, and of right-hemisphere stroke on subtests with visuo-spatial and processing speed demands. Aphasia had an additional effect on language, working memory and processing speed subtests. Findings confirm the pattern of cognitive deficits found with older versions of the WAIS and suggest that the WAIS-IV detects cognitive deficits in stroke patients.

Communicative Effectiveness

Groups of aphasic patients and their spouses generated a series of communication situations that they felt were important in their day-to-day life. Using criteria to ensure that the situations were generalizable across people, times, and places, we reduced the number of situations to 36 and constructed an index that allowed the significant others of 11 recovering and 11 stable aphasic individuals to rate their partners' performance in the situations on two occasions 6 weeks apart. These data were then used to evaluate the psychometric properties of the Communicative Effectiveness Index (CETI) as a measure of change in functional communication ability. Further application of a generalization criterion reduced the final index to 16 situations. Results showed the CETI to be internally consistent and to have acceptable test-retest and interrater reliability. It was valid as a measure of functional communication according to the pattern of correlations found with other measures (Western Aphasia Battery, Speech Questionnaire, and global ratings). Finally, it was responsive to functionally important performance change between testings. Further research with the CETI and its usefulness for clinicians and researchers are discussed.

Abstract Objective: Patients with unilateral stroke commonly show hemispatial neglect or milder contralesional visuoattentive deficits, but spatially non-lateralized visuoattentive deficits have also been reported. The aim of the present study was to compare spatially lateralized (i.e., contralesional) and non-lateralized (i.e., general) visuoattentive deficits in left and right hemisphere stroke patients. Method: Participants included 40 patients with chronic unilateral stroke in either the left hemisphere (LH group, n = 20) or the right hemisphere (RH group, n = 20) and 20 healthy controls. To assess the contralesional deficits, we used a traditional paper-and-pencil cancellation task (the Bells Test) and a Lateralized Targets Computer Task. To assess the non-lateralized deficits, we developed a novel large-screen (173 × 277 cm) computer method, the Ball Rain task, with moving visual stimuli and fast-paced requirements for selective attention. Results: There were no contralesional visuoattentive deficits according to the cancellation task. However, in the Lateralized Targets Computer Task, RH patients missed significantly more left-sided than right-sided targets in bilateral trials. This omission distribution differed significantly from those of the controls and LH patients. In the assessment of non-lateralized attention, RH and LH patients missed significantly more Ball Rain targets than controls in both the left and right hemifields. Conclusions: Computer-based assessment sensitively reveals various aspects of visuoattentive deficits in unilateral stroke. Patients with either right or left hemisphere stroke demonstrate non-lateralized visual inattention. In right hemisphere stroke, these symptoms can be accompanied by subtle contralesional visuoattentive deficits that have remained unnoticed in cancellation task.

The Relationship

The study investigates the relationship between the performance of stroke patients on tests of perception and language. It has been suggested that stroke patients with left hemisphere damage may perform poorly on tests of visual perception due to language problems affecting their understanding of the task. Results indicated that there was no significant difference between stroke patients with right hemisphere, dysphasic left hemisphere and non-dysphasic left hemisphere damage on perceptual tests. Few significant correlations were found between scores on the perceptual tests and scores on the language tests, suggesting that the poor performance of dysphasic patients cannot be explained by language impairment alone.

Six stroke patients were studied using a dichotic listening¹ CV task, 4 with left hemisphere infarction, 2 with right hemisphere infarction. It was observed a «lesion--effect», a shift of hemisphere prevalence to the side opposite a brain lesion. The authors suggest that the lesion-effect can be explained by the auditory extinction phenomenon at the linguistic level.

The combined interactions of mode and tempo on emotional responses to music were investigated using both self-reports and electroencephalogram (EEG) activity. A musical excerpt was performed in three different modes and tempi. Participants rated the emotional content of the resulting nine stimuli and their EEG activity was recorded. Musical modes influence the valence of emotion with major mode being evaluated happier and more serene, than minor and locrian modes. In EEG frontal activity, major mode was associated with an increased alpha activation in the left hemisphere compared to minor and locrian modes, which, in turn, induced increased activation in the right hemisphere. The tempo modulates the arousal value of emotion with faster tempi associated with stronger feeling of happiness and anger and this effect is associated in EEG with an increase of frontal activation in the left hemisphere. By contrast, slow tempo induced decreased frontal activation in the left hemisphere. Some interactive effects were found between mode and tempo: An increase of tempo modulated the emotion differently depending on the mode of the piece.
