简要总结
There is an evidence gap on whether meditation may improve behaviorally measured attention after stroke, but preliminary research is promising. This study is the first-ever investigation of whether mantra meditation may improve chronic, severe impairment in attention after stroke.
详细描述
The study is non-concurrent, multiple-baseline, across-subjects, single-case research design (SCRD). The central hypothesis is that mantra meditation (independent variable) will be associated with improvement on 1 or more tests of behaviorally measured sustained attention (dependent variable). The mantra in this study is the syllable "um" and is not assigned any spiritual, religious, or affective meaning. The mantra is repeated aloud together by the subject and the PI for a duration of 30 minutes in each session. This procedure constitutes meditation for the purposes of this study. There are 9 session of meditation (3 times per week for 3 weeks). Attention is measured in each of these sessions as well as in 3 separate testing sessions that precede the intervention period.

研究组 & 干预措施
mantra meditation
Each session of mantra meditation lasts for 30 minutes. The participants in each session comprise 1 subject and the PI. In each session, the subject and the PI co-participate in repetitive intonation of a pre-specified mantra. Intervention is comprised of 9 sessions, each of which occurs on a separate weekday at approximately equal intervals over a total intervention period of 3 weeks.
干预措施: mantra meditation (Behavioral)
结局指标
主要结局
Sustained Attention to Response Task, Fixed Version
时间窗: through study completion; average of 4 weeks
SARTfixed is in the class of attention tests called continuous performance tests, a class which has a long history of use to measure sustained attention (Shaleva, Ben-Simon, Mevorachc, Cohen, \& Tsald, 2011). SARTfixed is a 5-minute computerized test based on the standard version of the SART, which was developed to measure sustained attention in subjects with right-hemisphere acquired brain lesions (Robertson, Manly, Andrade, Baddeley, \& Yiend,1997b). Manly and colleagues (2003) demonstrated that in subjects with neurological impairment, SARTfixed was a more pure measurement of sustained attention than standard SART. SARTfixed also had comparatively more likelihood than standard SART for accurately discriminating between healthy volunteers and individuals with neurological impairment.
