| OBJECTIVE: Balance and cognitive declines with aging lead to increased risk of fall.So far,however,The association between the balance ability,cognitive and emotion is unknown.The aim of the study is to analyze the relationship between balance,cognitive and emotion in older individuals.Furthermore,to determine the effects of gender,age and exercise habits on balance,cognitive and emotion.METHODS: As a sample I took Ninety-two older adults from a community-based sample,Chinese(30 males,62 females),aged 55 years and above,participated in this study.Participants were enrolled and completed balance test,cognitive function test and emotion states test.Static balance testing was done in the following order:(1)single-leg stance with right or left foot,eyes open or closed;(2)stance with both feet,eyes open or closed.The dynamic balance measurement was represented by gait testing.Cognitive parameters included simple reaction time test and Visuospatial memory test.Emotion tests were assessed by using the State Trait Anxiety Inventory-state portion(STAI-Form Y),Beck Depression Inventory(BDI)and Rosenberg Self-esteem Scale(RSES).The collected data were analyzed by independent T-test and correlation analysis using the SPSS program(ver.20).RESULTS: The data indicated that: 1)No significant differences(p>0.05)were demonstrated for elderly people selected age group.2)In the static balance measurements,the length of SKG in single-leg standing with eyes open conditions was found to be significantly(p<0.05)longer in older adult group compared to midlife adult group.In the dynamic balance measurements,the ambulation index result was found to be significantly(p<0.01)higher in midlife adult group compared to older adult group.3)In the static balance measurements,the X-axis value in center of pressure,the Y-axis value in center of pressure,the max distance and ellipse area in double-leg standing with eyes open conditions were found to be significantly(p<0.01)larger in control group compared to exercise group.The Y-axis value in center of pressure and ellipse area in double-leg standing with eyes close conditions were found to be significantly(p<0.01)larger in control group compared to exercise group.In the dynamic balance measurements,the average step cycle and ambulation index result were found to be significantly(p<0.01)higher in exercise group compared to control group.The coefficient of variation was found to be significantly(p<0.01)lower in exercise group compared to control group.The average of left step length was found to be significantly(p<0.01)lower in exercise group compared to control group.In the cognitive function test,SRT was found to be significantly(p<0.05)lower in exercise group compared to control group.VMT was found to be significantly(p<0.05)larger in exercise group compared to control group.In the emotion test,RSES was found to be significantly(p<0.01)higher in exercise group compared to control group.S-AI was found to be significantly(p<0.01)lower in exercise group compared to control group.4)The simple reaction time was a positive correlated with the length of SKG(r=0.33,p<0.01)in single-leg standing with eyes close conditions.The simple reaction time was a positive correlated with the coefficient of variation on right limb(r=0.36,p<0.01)in gait test.BDI was a positive correlated with the max distance(r=0.31,p<0.01)in single-leg standing with eyes open conditions.CONCLUSIONS: 1)In the elderly population,gender has little effect on balance ability,cognitive function and emotional state.2)For the elderly over 55 years of age,age factors have the greatest impact on dynamic balance ability.Moreover,older adult are worse than midlife adult.3)Those who have good exercise habits in the elderly have better balance,cognitive and emotional status rather than those who do not have exercise habits in the elderly.This finding indicates that exercise may become an effective non-drug treatment to reduce the risk of falls.4)These results suggest that the balance performance is associated with cognitive and emotion in older individuals. |
