The Effect Of Adaptive Physical Activity On The Static Balance Ability Of Children With Autism

Objective:Autistic children have postural control problems and It is of great significance to improve their static balance.This study aims to observe:1.Changes in single leg standing time.2.Changes in control of body mass under different state by static balance instrument.3.Changes in reaction time.To explore the mechanisms of these changes.So that can provide the theoretical basis and provide reference for applying adaptive physical activities in the field of rehabilitation and training among autistic children.Methods:Autistic children were recruited and divided into experimental group and control group.During the experiment,all the children were not involved in other sports activities,and the experimental group participated in adaptive physical activities for 8 weeks(5 times per week,60 minutes peer time)while the control group did not.We did a pre-test,a post-test and a retention test which is after eight weeks on children including single leg standing balance test,static balancing instrument test,and lower limb reaction time test.The static balancing instrument test was divided into different conditions including eyes open,eyes closed,with and without foam and with one foot stood for 3 seconds while two feet stood for 10 seconds.Observing the changes in the pre-test,post-test and retention test.Results:1.In single leg standing balance test,the time improvement of experimental group in the post-test and retention test increased more than control group in both left leg and right leg with eyes open and closed.Right leg with eyes open in post-test had significant difference(p<0.05),while others didn't.2.In the static balancing instrument test,the balance ability of the experimental group and the control group had the trend of improvement which were different,there was no significant difference between the two groups.3.In the reaction time test,the experimental group improved more than control group in post-test,but in retention test,the reaction time of experimental group slightly increased in left foot,and right foot increased a lot in right foot,there was no significant difference between the two groups in all the conditions.Conclusion:After 8 weeks of adaptive physical activity intervention:1.Single leg standing time is increased and maintains very well,showing increase after intervention.2.The ability to control the body center of gravity is different in different situation including eyes open,eyes closed,single feet,foot,with or without sponge,some indicators have a trend of improving,but not significant.3.There is a trend of improving in lower extremity response time,but shows no significant,and can not maintain after the intervention.
