| Objectives:Stroke is a common and frequent disease in quinquagenarian which will led movement dysfunction. Therefore, the effect of motor function rehabilitation after stroke is extremely important.This study aim to explore taijiquan exercise in patients with stroke and to discuss the rehabilitation results on movement balance, standing on one foot, walking and index finger tapping. And transcranial magnetic stimulation(TMS) was observed before and after taijiquan exercise. So that the brain changes in the excitability movement of the central nervous can be find.This study can reveal the effect of taijiquan exercise on the rehabilitation for patients with stroke and the effect of neural plasticity mechanism. It also can provide theory and method basis of sports rehabilitation therapy for patients with stroke. And it will promote Chinese traditional taijiquan by science popularization with theoretical and application value.Methods:Since December 2014- February 2015, through the Chinese people’s liberation army 411 hospital to recruit meets the requirements 16 cases of patients with stroke as experimental object,which were randomly divided into taiji group(experimental group) and traditional rehabilitation group(control group). The experimental group has 8 people, control group has 8 people.According to the experimental plan both groups go for six months of exercise intervention,2 times a week(experimental group one concentration practice, one home exercise;control group two times are practice at home), 60 min each time. Exercise intensity in the process of movement of field monitoring, control the rate of 40% to 60% of the bull’s-eye, wear heart rate table, real-time monitoring of heart rate.The BERG balance scale, time limit stand up and walk TUGT, standing on one foot, hand index finger tapping DFTT test used to evaluate movement function before and after the experiment. The SF- 36 scale score used to evaluate the quality of life. Nerve excitability using transcranial magnetic stimulation(TMS) stimulated hand back muscle motion to evoke potential amplitude. Excel was used to set up a database. SPSS19.0 statistical software was used to analysis data. The subjects of general situation and the function parameters use mean + /- standard deviation. Count data use chi-square test. When measuring data conforms to normal distribution,paired samples T test was used in group. Independent sample t-test was used between groups;When data is not in accord with normal distribution, the nonparametric tests will be used.Result:1.The quality of lifeAfter six months of exercise intervention, the quality of life score of experimental group before and after experiment was no significant difference(p > 0.05), but the health changes before and after experiment has a very significant difference(p < 0.01); the quality of life score and health Changes of control group before and after was no significant difference(p > 0.05). The survival quality of the two groups before and after experiment was no significant difference(p >0.05); Before experiment, healthy changes have no significant difference between groups(p >0.05), but after experiment the score has a very significant difference(p < 0.01), and the experimental group was better than the control group.2. The indicators of the movement function test(1) Balance ability: after six months of exercise intervention, two groups of Berg balance scale score become more significant difference(p < 0.05)before and after experiment, and the control group after the practice is lower than before; Before experiment there was no significant difference between groups(p > 0.05), after experiment comparison between groups have significant difference(p < 0.05), and the experimental group scored higher than the control group.Experimental group standing on one foot time practice has a very significant difference(p < 0.01),but the control group comparison between before and after experiment was no significant difference(p > 0.05);Comparison between two groups before and after experiment were no significant difference(p > 0.05).(2)walking ability. The TUGT time of experimental group Comparison before and after experiment had significant difference(p < 0.05), but the control group was no significant difference(p > 0.05); The TUGT time of the two groups before and after experiment comparison had no significant difference(p > 0.05).(3) the index finger tapping capability. Experimental group of DFTT tests before and after experiment was no significant difference(p > 0.05), but the healthy side have significant difference(p < 0.05);The control side compared with the contralateral DFTT test before and after experiment were no significant difference(p > 0.05);Two groups of side and health side DFTT test between groups before and after experiment was no significant difference(p > 0.05).3. Nerve excitability(1) The diseased side: the exercise intervention continue 6 months, after 12 weeks and 24 weeks practice compared with before the practice of hand back muscle motion evoked potential amplitude have significant difference(p < 0.05); 12 weeks compared with 24 weeks practice has Result:.very significant difference(p < 0.01).Control group before and after practice was no significant difference(p > 0.05). Control group after 12 weeks and 24 weeks practice was no significant difference(p > 0.05).Two groups of the back of the hand motor evoked potential amplitude was no significant difference between groups(p > 0.05) on each practice.(2) the contralateral: The experimental group practice and before practice, after 12 weeks and 24 weeks and 12 weeks and24 weeks after practice and practice before compared with the contralateral hand back muscle motion evoked potential amplitude have significant difference(p < 0.05);Control group practice and before practice, after 12 weeks and 24 weeks and 12 weeks and 24 weeks after practice and practice before is no significant difference(p > 0.05).Two groups of the contralateral hand back muscle motion evoked potential amplitude after 12 weeks practice comparison between groups were no significant differences(p > 0.05), but after 24 weeks of practice between groups had significant difference(p < 0.05).Conclusion:1.6 months taijiquan practice overall health changes in patients with stroke have obvious improvement effect,but the overall quality of life is not obvious.2.6 months taijiquan practice can effectively improve movement function in patients with stroke, mainly is: taijiquan practice significantly improve the balance ability, walking speed,ability to stand on one foot and finger tapping of the patients with stroke.3.6 months taijiquan practice for stroke patients health side and contralateral side muscle motion evoked potential amplitude were increased obviously, and can effectively improve the nerve excitability. |
