| Purposes: The purpose of this study was to investigate the effects of physical function training on the balance ability of adults with tertiary mental retardation.Methods: Twenty adults with grade 3 mental retardation were selected as subjects,and they were completely randomly divided into an experimental group and a control group,with 10 persons in each group.The literature group method,expert interview method and questionnaire survey method were used to design the training actions and plans of the experimental group.The experimental method was used for experimental research.The experimental group was used for physical function training.The control group was used for conventional jogging and jogging exercises.It is guaranteed by a doctor.The experiment lasts for 12 weeks and is trained 3 times a week.The balance index test is performed before and after the experiment.The data is analyzed and analyzed by mathematical statistics.Result:(1)Before and after the experiment,there was a significant difference in left-eye standing time(left foot)between eyes before and after the experiment(P<0.01).There was a significant difference(P<0.05),and the standing time with one eye(right foot)was significantly improved after the experimental intervention;there was no significant difference between the left and right eyes with one foot standing before and after the experiment in the control group(P>0.05).(2)There was a significant difference between the left and right eyes with one foot standing before and after the experiment in the experimental group(P<0.01).There was no significant difference in the standing time of one foot with closed eyes of the left and right feet before and after the experiment(P>0.05).(3)In the Good Balance test,the index of standing with both feet open with eyes before and after the experiment in the experimental group: there was a significant difference in MLV(P<0.01),and there was a significant difference in MLD,APV,and APD(P<0.05).The data of each indicator decreased significantly after the experimental intervention Small;control group with open eyes and feet standing before and after the experiment: no significant differences in MLV,MLD,APV,APD(P> 0.05).(4)In the Good Balance test,the index of standing with both eyes closed with eyes before and after the experiment in the experimental group: there was a significant difference in MLV(P<0.01)and a significant difference in MLD(P<0.05).After the experimental intervention,the MLV and MLD data were significantly reduced,and the APV There was no significant difference with APD(P> 0.05);the control group with closed eyes and two feet standing indicators: MLV,MLD,APV,APD did not decrease significantly(P> 0.05).(5)There was a significant difference in the straight line performance of the experimental group before and after the experiment(P<0.01).The straight line performance of the experimental group significantly improved after the experimental intervention,and there was no significant difference in the straight line performance of the control group(P>0.05).(6)There was a significant difference in the performance of the in-situ step with closed eyes before and after the experiment in the experimental group(P<0.01),and the performance of the in-situ step with closed eyes was significantly improved after the experimental intervention.(7)In the Y-balance test,there was a significant difference in the performance of the left and right lower limbs before and after the experiment in the experimental group(P<0.01),and there were significant differences in the performance of the left and right lower limbs on the postero-lateral,right and lower hind limbs(P<0.05).After the experimental intervention,the scores of the posterior mid-left side,the postero-lateral left lower limb,the postero-medial side of the right lower limb,and the postero-lateral side of the right lower limb were significantly improved.There was no significant improvement in the Y-balance performance of the control group(P>0.05).There was a significant difference in the comprehensive value of the lower extremities on both sides of the experimental group before and after the experiment(P<0.01),and the comprehensive value of the lower extremities of the two sides increased significantly after the experimental intervention;there was no significant difference in the comprehensive value of the lower extremities on both sides of the control group(P>0.05).Conclusions:(1)Physical function training can effectively improve the static balance ability of adults with tertiary mental retardation in the state of standing with their eyes open on their feet,which is expressed as: the speed of movement of the body’s center of gravity in the X-axis(coronary plane),the distance of X-axis(coronary plane)movement,Y The axis(sagittal)movement speed and Y axis(sagittal)movement distance were significantly improved.(2)Physical function training can effectively improve the static balance ability of adults with tertiary mental retardation in the state of standing with their eyes closed and their feet closed.The performance is as follows:the center of gravity of the body moves on the X-axis(coronary plane)and the X-axis(coronary plane)moves significantly.Improvement,in which the center of gravity of the body moves on the Y-axis(sagittal plane)and the Y-axis(sagittal plane)movement distance has no significant change.(3)Physical function training can effectively improve the dynamic balance of the lower limbs of the three-stage intellectually disabled adults with their eyes open.Significant change.(4)Physical function training can effectively improve the ability of dynamic balance in the eyes closed state of adults with tertiary mental retardation,which is manifested in the following: the performance of walking in a straight line and keeping eyes closed has improved significantly.(5)Under the guidance of theory,a set of three-level physical function training program for adults with mental retardation was specifically designated,which can effectively improve the balance ability,improve the quality of life and promote the return to society. |
