Analysis Of The Static Balance Function Of The Elderly And Preliminary Establishment Of The System Of The Evaluating The Static Balance Function Of The Elderly

The function of balance is the ability to maintain body in a particular posture, and is also a ability to control the centre of body mass. The sense of balance comes from visual system, the vestibular system and somatosensory in muscle and jiont combinely. The three factors should have acted in harmony. The degeneration of the balance control system of the elderly leads to somewhat sway in walking and falls. It is a major factor of injuries and loss of life for the elderly. So. with the increase in our ageing population and increased lite expectancy of our elderly the importance of function of balance is becoming ever more critical. Recording and analysing the track of the centre of pressure of subjects is a very important mathod of analysing and evaluating precisely the static balance function of the elderly. It will be very significative to establish a simple and accurate system of evaluating the static balance function of the elderly.113 elderly participated in our study (male totaled 48, mean age 66.5,female totaled 65,mean age 64.00). every subject took six tests in six different postures totally: standing quietly on the force plate with double feet and eye opening lasting for 60s;with double feet and eye closing lasting for 60s;with single foot and eye opening lasting for 15s:with single foot and eye closing lasting lor 5s;\vith Romberg posture and eye opening lasting for 40s and Romberg posture with eye closing lasting for 20s.We recorded the tracks of the centre of pressure of the elderly and Created 162 indicc including PER1SOA and selected 25 indice from them by ANOVA and selected 6 indice as factors for evaluation system by multi-gene analysis.A system of evaluating the static balance function of the elderly was established in the end.According to my study conclusion can be drown as following: 1) the elderly maintain their body balance in static mainly depending on their low limbs; 2) with ageing, the static balance function is declining gradually, but after their 65,it declines quickly; 3) the static balance function of the elderly is independent of their gender and figure; 4) the posture that can indicate the static balance function of the elderly are DC SO LO and LC; 5) the system of evaluating static balance function of the elderly based on the analysing the indice of static balance function of the elderly can indicate the static balance function somewhat exactly.it has somewhat applied value.
