To examine the relationships between impairments in limb muscle strength soon after stroke, a secondary analysis of a data base of 48 patients with stroke was undertaken. Measurements of isometric muscle strength obtained bilaterally from eight muscle actions and recorded in the data base were retrieved for analysis. Most of the strength measures correlated significantly with one another. The measures of muscle strength showed high internal consistency in each limb, on each side, and over-all. Principal components analysis and cluster analysis indicated that the closest relationships were between muscle actions of the upper limb contralateral to the stroke (the "paretic" side), limb muscle actions of the side ipsilateral to the stroke (the "nonparetic" side), and muscle actions of the lower limbs. These findings may reflect the organization of the central nervous system following stroke.

Preliminary evaluation of the neuropsychological status of three Chinese-speaking patients receiving angioplasty and stenting of extracranial cerebral arteries showed no significant decline in their performance on cognitive tasks measuring (1) memory function, verbal and nonverbal memory, (2) attention, and (3) cognitive processing speed. Although angioplasty and stenting of extracranial cerebral arteries did not appear associated with detrimental changes in the cognitive status of the two patients completing all cognitive tasks, their relation must be confirmed as a neuropsychologically safe measure for reducing the risk of stroke in Chinese with significant extracranial cerebral artery stenosis by a randomized controlled study with a much larger sample.

A number of rating systems are available to evaluate emotional communication in a single modality. The main purpose of this study was to develop procedures to train human raters to evaluate posed expressions of emotion across three different channels of communication, i.e., facial, prosodic/intonational, and lexical/verbal. These procedures were used to evaluate posed emotional expressions produced by individuals with unilateral brain lesions from stroke. Posers in this preliminary report were two right brain-damaged, two left brain-damaged, and two normal control right-handed adults who were matched on demographic and neurological factors. Eight emotional expressions, both positive and negative, were produced in three channels and rated for intensity, pleasantness, and category accuracy. 15 normal adults served as raters, five per channel. The rating procedures were comparable across channels, with analogous properties, and yielded substantial interrater agreement. In this small sample of posers, it was observed that the expressions of the right brain-damaged group were rated as the least accurate and those of the left brain-damaged group as the most intense. When patterns of individual performance across the channels were examined, performance was quiet consistent for the normal controls yet variable for the right brain-damaged persons. These observations are in keeping with the notion that patients with right hemisphere pathology have difficulty in emotional communication. In summary, these findings suggest that comparison of emotional expressions across multiple channels is feasible.

The purpose of this study was to measure and compare the durations of exhalation (DE), inhalation (DI), and inhalatory apnea (DAI) expressed as percentage of stroke-cycle duration using two groups (more expert and less expert) of 6 front crawl swimmers each at near 100-m speed (high speed) and 800-m speed (low speed). Two breathing conditions were considered, breathing to the preferred side with and without a nose-clip. The relationships between stroking characteristics (swimming speed, stroke rate, and stroke length) and the three durations of breathing were examined as a function of skill and swimming speed. The data show that use of a nose-clip does not significantly change those measures. At high speed, the more expert group had a lower inhalation and a higher exhalation than the less expert group. The stroke rate correlated with speed .92 (p<.01) and was mainly associated with inhalation (r=-.78, p<.01). Inclusion of exhalation as a second variable improved significantly (p<.01) the accuracy of the regression up to .97. At low speed, the less expert had lower inhalatory apnea than the more expert. Stroke length correlated with speed .86 (p<.01) and was mainly associated with inhalatory apnea (r=.70, p<.05). At high speed, the more expert had a lower inhalation than at low speed, while durations of exhalation and inhalatory apnea did not vary significantly. On the contrary, the less expert had a lower exhalation and a higher inhalatory apnea, while duration of inhalation remained relatively unchanged. The present study shows that these durations and their relations to stroking characteristics could be considered significant indicators of skill in swimming.

Language performance was assessed in three groups of children (16 boys and 14 girls) with sickle cell disease: those with stroke, without stroke, and at risk for stroke. Scores of the three groups did not differ significantly on language comprehension, language expression, spatial orientation, or on overall combined performance scores. Such results have positive medical implications.

A study was carried out to examine how people react to acts of intimacy between parent and child. Based on an extensive series of studies reported in 1998 by Reis who found less intimate interactions between two men who are friends than between men or women or between two women who are friends, it was reasoned that intimacy between two males may violate norms of our culture, so it was predicted that people would react less favorably to intimacy between father and son than to intimacy between father and daughter, mother and daughter, or mother and son. Men (n = 19) and women (n=26), most of whom were 18-24 years of age, read versions of a mother or father having an intimate interaction (lap-sit, hair-stroke, hug/kiss) with an 11-yr.-old daughter or son and then rated the act on a 7-point scale from good to bad. As predicted, the undergraduates rated intimate interactions between father and son less favorably than those between father and daughter, mother and daughter, and mother and son.

It is unclear whether the cortical representation of swallowing is lateralized to the left cerebral hemisphere, right hemisphere, or bilaterally represented. As dysphagia is common in acute stroke, it is important to elucidate swallowing lateralization to facilitate earlier detection of stroke patients who may be at greater risk for dysphagia and aspiration. In this study, a modified dual task paradigm was designed to study laterality of swallowing in a group of 14 healthy, young, right-handed, male adults. The subjects were studied at baseline and with interference. Baseline conditions, performed separately, were continuous swallowing, finger tapping using the right and left index fingers, and word repetition. Interference tasks, including tapping with the right index finger, tapping with the left index finger, and word repetition, were completed with and without swallowing. Finger-tapping rate was measured, and x-ray samples of the swallowing task were taped to measure swallowing rate and volume swallowed. At baseline, the rate of tapping the right index finger was significantly faster than that of the left index finger. There was a significant decline in the tapping rates of both left and right index fingers with swallowing interference. The volume per swallow was significantly reduced during the interfering language task of silent repetition. These results offer partial support for a bilateral representation of swallowing as well as suggest an important left hemispheric contribution to swallowing. However, it cannot be concluded that the left hemisphere is more important than the right, as a comparable right hemisphere task was not studied.

A study involving results of the PGA Tour, Senior PGA Tour, and the LPGA Tour investigated whether "choking under pressure" occurs among professional golfers. Players were individuals who either were leading going into the final round or within five strokes of the lead. It was hypothesized that players who were one stroke from the lead and to a lesser extent players who were leading should have higher final round scores than those players who were two or more strokes from the lead ("choking"). However, the results did not support the choking hypothesis. Players who were leading going into the final round won the majority of the time.

Previous research has suggested that children with sickle cell disease may exhibit cognitive deficits even in the absence of direct cerebrovascular involvement (stroke). This study was designed to assess specific attentional deficits in children with sickle cell disease. 12 children with sickle cell disease (Hb SS) with a prior history of stroke, 14 children with sickle cell disease (Hb SS) without evidence of stroke, and 13 similar aged siblings (Hb AA or Hb AS) were compared on measures of attention, intellectual functioning, achievement, and adaptive functioning. Significant differences were found between children with sickle cell disease (with or without stroke) and healthy controls on a timed test of visual scanning, the Coding subtest of the Wechsler Intelligence Scale for Children-Revised, and subtests of Reading, Arithmetic, and Spelling from the Wide Range Achievement Test-Revised. The differences between children with sickle cell disease and their healthy siblings appear to be the result of strokes rather than sickle cell disease itself as children with sickle cell disease without strokes did not significantly differ from controls. Implications for the effects of sickle cell disease and stroke on academic performance are discussed.
