| Summary: | 碩士 === 中山醫學大學 === 醫學研究所 === 95 === Background：Each of body position have involuntary and continuous tremor. Physiology tremor found long ago but there were little relevant research. The origin cause of formation of Physiology tremor and mechanism of forming are not clear yet. Scholar recently found that the periodic signal of Physiology tremor has been closely related with cerebral cortex activity. Now Physiology tremor is the important clue that considered to probe into the brain simplifies control movements. Many studies apply the result of measure all kinds of physiology tremor to clinical diagnosis. But no one uses the form of tremor to assess the stroke patient. There are no study about Physiology tremor of head, neck and trunk yet. So, we wonder to know what role Physiology tremor is acted in static trunk control and coordination between trunk and limbs. Material and method: 33 stroke patients participate in this research, there are 21 man and 12 women. Each experimenter was assessed to PASS-TC scale, the ability of sitting/standing balance in static/dynamic state. The outcome of those evaluation represents the truck control ability. Experimenters sit on the high stool and Triple-axis accelerometers is fixed in five different parts of experimenter''s truck. Experimenters under the 12 kinds of conditions and we collect Triple-axis accelerometers vibrations signals of competence and vertical direction for 20 seconds twice. This study uses SPSS 11.0 editions of statistics software. It uses univariate ANOVA and repeated measures multiple ANOVA for multiple comparative analysis. Then compare its difference outcome with Post-Hoc tests. Results：Different to support state have obvious difference average of root square (signal of tremor) in five triple-axis accelerometers (p<0.000). Air pillow condition cause five triple-axis accelerometers average of root square(signal of tremor) difference (α=0.000). Secondly, Eye condition in five triple-axis accelerometers average of root square (signal of tremor) do not have obvious difference in statistics. Three kinds of different postural pointing task have obvious differences in five triple-axis accelerometers average of root square. In three kinds of states ,raise one hand make Triple-axis accelerometers average of root square in frontal region have obvious difference in statistics (α= 0.004 and 0.006). Raise left hand have obvious difference in statistics for parameter of R'' t inferior angle of scapular (α=0.013).
Raise left hand have obvious difference in statistics for parameter of L'' t inferior angle of scapular (α=0.012). Raise the right hand has obvious difference in statistics for parameter of R'' t PSIS (α=0.007). Discussion and Conclusion： This result of study shows that seatpad support surface and raise upper limbs will cause trunk tremor to obviously become severe to hemiplegia stroke patients in static sitting. But visual feedback has not influenced to hemiplegia stroke patients in static sitting balance. This tell us that the seatpad offers a firm support which have very great help and influence to stroke patient in sitting balance. Raise the hand can be a treatment program in sitting balance and activity of daily living in clinical therapy of Stroke patient. In order to understand the relationship between quantity of physiology tremor examines and trunk control ability, we propose to do more related studies abut normal person and other neural disease patient further.
