明目健脑操防治近视眼效果的多元统计分析

Effect of improving eyesight brain tonic exercise in preventing and curing myopic eye: A multiple-statistical analysis

目的:对坚持开展3个月预防近视眼保健操的25名学生的训练效果进行多元统计分析,并与对照组比较。方法:实验于2003-03/06以焦作市城区7所中小学作为明目健脑操预防近视眼的实验基地,对近2万名学生训练后的效果进行多元统计分析。本文报告随机抽取40名学生,分为明目健脑操训练组25名,空白对照组15名,使用多元统计分析中的显著性检验方法分析数据资料。①明目健脑操的具体做法:整套操共分6节。第1节按揉眼内穴;第2节顶按眼上穴;第3节按揉眼外穴;第4节按揉眼下穴;第5节轮刮眼眶,按揉风池;第6节旋运睛体,极目远眺。之后闭目内视,眼睛放松,想象自己的眼球被“绳索”向后牵拉,拉的不能再拉时,觉得眼球由长拉扁时再挣眼向远处绿色植物眺望,让眼球变圆。远看时瞪大眼睛,不求马上看清,但求眼球变圆,最后做几次深呼吸,做操结束。②明目健脑操训练组按以上方法进行训练,1次/d,共3个月。空白对照组未进行任何保健操训练。③对明目健脑操训练组实验前后视力是否有显著性提高进行秩和检验,实验前后两组视力提高程度的比较行多元统计显著性检验。结果:按意向处理分析,随机抽取40名学生的数据资料进行多元统计显著性分析。①实验前后明目健脑操训练组学生视力随机抽样及秩和检验结果:训练3个月后平均裸眼视力比实验前提高0.08,视力提高率为32.89%;训练3个月后视力不良率比实验前下降8.94%(U=4.7648,P<0.01)。②实验前后空白对照组学生视力随机抽样情况:实验后3个月,学生裸眼视力不良率升高1.71%,但与实验前比较差异无显著性意义(U=0.7577,P>0.05)。结论:多元统计分析结果表明,高效明目健脑操是中学生自我调控防治近视眼的有效方法。

AIM： To observe the effect of improving eyesight brain tonic exercise on preventing and curing myopic eye of 25 students within 3 months and compared with those in control group. METHODS： The experiment was completed in 7 middle schools and primary schools in Jiaozuo from March to June 2003. Results of 20 000 cases were compared with multiple-statistical analysis. In this study, 40 cases were selected randomly and divided into training group （n=25） and blank control group （n=15）. Data were analyzed with significance test among multiple-statistical analysis. ① Improving eyesight brain tonic exercise in details： There were 6 parts in total： pressing Yannei, Yanshang, Yanwai and Yanxia acupoints, scaling orbit ahernatively and pressing Fengchi acupoint, and turning eyeball to gaze into the distance. And then, examinates closed their eyes for relaxing, and imaged that their eyeball was dragged backwards with rope. When they felt their eyeballs were dragged flatly, they opened eyes to look far away green plant so as to make the eyeballs round. Examinates stared at distance just only for making eyeballs round. Deep breath was made at the end of eye exercise. ② Cases in training group did the exercise as mentioned above, once a day for 3 months. Cases in blank control group did not do any exercise. ③ Whether eyesight was improved before and after improving eyesight brain tonic exercise or not was analyzed with rank sum test, and improved degree of eyesight was compared with significance test of multiple-statistical analysis before and after study. RESULTS： According to intension, data of 40 students were analyzed with multiple-statistical analysis. ① Results of eyesight in training group with rank sum test before and after exercise： Average naked vision was improved 0.08 after 3-month training, and the increasing rate af eyesight was 32.89%; poor rate of eyesight was decreased 8.94% after 3-month training （U=4.7648, P 〈 0.01）. ② Random samples of students in blank control group before and after experiment： Poor rate of eyesight was increased 1.71% after 3- month training, but there was not significant difference from that before experiment （U=0.7577, P 〈 0.05）. CONCLUSION： Multiple-statistical analysis shows that improving eyesight brain tonic exercise is an effective method to prevent and cure myopic eye for students by themselves.
