The cortical organization in language tasks of Mandarin and Uyghur speakers / 中华物理医学与康复杂志

Objective To observe the difference in activated brain regions when speaking Mandarin and Uyghur.Methods Blood oxygenation level dependent magnetic resonance imaging (BOLD-fMRI) was used to scan the brains of 30 healthy,right handed volunteers-15 native Uyghur speakers and 15 native Mandarin speakers-while they performed semantic identification and verb generation tasks.The fMRI data were used to generate statistical parametric maps of the brain areas activated by each task.Results In the semantic identification task the left anterior cingulate gyrus (BA23) and the midline mesophyll wedge were activated significantly more strongly in the Uyghur group compared with the Mandarin speakers.In the verb generation task the left inferior temporal gyrus (BA37),the inferior parietal lobule,the fusiform gyrus and the parahippocampal gyrus in the Uyghur group were all significantly more active.The right superior temporal gyrus (BA38) in the Mandarin group was significantly more active during verb generation than among the Uyghur speakers.Conclusions The brain regions activated during semantic processing and verb generation differ when speaking Uyghur and Mandarin.The cingulate gyrus and the praecuneus are more involved in Uyghur-language semantic processing,especially the left anterior cingulate gyrus.The right hemisphere is more important in Mandarin processing than in Uyghur.

Applying the Canadian occupational performance measure in the rehabilitation of stroke patients / 中华物理医学与康复杂志

Objective To observe the different needs of Uighur and Han stroke patients for oceupational activities using the Canadian occupational performance measure (COPM).Methods The COPM was employed to evaluate 51 stroke patients in hospital before and after treatment.Thirty were from the Han ethnic group and 21 were Uighur.The first evaluation was performed at admission to confirm their occupational activity problems.Interventions were then planned using a patient-centered occupational therapy model.At discharge the second evaluation was performed to assess and compare the effects of treatment.Results In the first evaluation,both the Uighur and Han stroke patients had problems with self-care activities which were more prominent than those with productive and leisure activities.Older Uighur patients had special occupational activity needs resulltng from their religious practices.Compared witb the first evaluation,the total performance and satisfaction scores had improved significantly by the second evaluation for both the Han and Uighur patients,but their satisfaction scores were lower than their occupational activities performance scores.Conclusion Different nationalities may have different occupational activities needs.The COPM is easy to use and helpful in confirming occupational activity problems.Its use can contribute to the plan ning of primary goals for rehabilitation and treatment programs and help assess the effect of rebabilitation.
