To evaluate the effectiveness of body support in compensating for decreased standing balance stability in elderly persons with visual impairment.
Standing balance was measured in a cross-section of elderly persons from two nursing homes--one for aged individuals with visual impairment, the other for aged individuals without visual impairment.
The subjects were 44 visually impaired persons with a mean age of 79.0 yrs and 39 people without visual impairment, mean age 76.3 yrs.
The area of gravity-center sway was measured with subjects standing on a gravicorder for 30sec in three positions: (1) without support, (2) with cane, (3) with light support by touching a wall.
Both men and women in the visually impaired group swayed more than their sighted counterparts when standing without support, the only statistically significant difference between the two groups. For all subjects, the greatest degree of sway occurred when subjects stood unsupported, and the least sway occurred when subjects touched a wall for support.
In visually impaired elderly persons, touching a wall for body support while standing is more effective than using a cane.
评估身体支撑对补偿视力受损老年人站立平衡稳定性下降的有效性。
对来自两家养老院的老年人进行横断面研究，测量其站立平衡能力。一家养老院收治视力受损的老年人，另一家收治视力正常的老年人。
44名视力受损者，平均年龄79.0岁；39名视力正常者，平均年龄76.3岁。
让受试者分别处于三种站立姿势（1）无支撑；（2）使用手杖；（3）轻触墙壁获得轻微支撑，使用重心记录仪测量受试者站立30秒时重心摆动面积。
视力受损组的男性和女性在无支撑站立时的摆动幅度均大于视力正常的同龄人，这是两组之间唯一具有统计学意义的差异。对于所有受试者而言，无支撑站立时摆动幅度最大，轻触墙壁获得支撑时摆动幅度最小。
对于视力受损的老年人，站立时轻触墙壁获得身体支撑比使用手杖更有效。
