Abstract：Objective To explore the difference in balance ability and motor control between the elder and the young.
Methods From July,2022 to February,2025,30 older adults(older group)and 30 young individuals(young group)were recruited in Huadong Hospital.Both groups underwent sensory organization test using a computerized dynamic posture recording system.Balance scores under six conditions,composite equilibrium score and strategy scores were recorded.The contributions of vision,somatosensation and vestibular function to balance under different stance conditions were analyzed.
Results The balance scores were lower in the older group than in the young group under the conditions of eyes open/un-stable surface,eyes closed/unstable surface,and visual conflict/unstable surface(t>3.887,P<0.05),as well as the composite equilibrium score(t=5.603,P<0.05),visual and vestibular scores(t>3.815,P<0.05),and strat-egy scores under all six conditions(t>2.496,P<0.05).
Conclusion Posture control ability decreases in older adults,mainly for decreasing visual and vestibular inputs and im-pairing in ankle and hip strategies.
