The influence of neurological or balance dysfunction on cognitive impairment has not been well studied. We compared the results of the balance test, measured by either head or foot sway to consider whole body sway, with those of the cognitive impairment test.
Individuals of either gender, aged over 60 years, underwent a 30 s balance test. We measured sway while standing on one-leg or two-legs. Sway was evaluated by the distance or area of movement of the head or foot pressure. We also evaluated the effect of visual condition: eyes-open (EO) or -closed (EC). The Mini-Mental State Examination (MMSE) was used to evaluate the degree of cognitive impairment.
The head sway area standing on one leg was significantly correlated to MMSE score with EO (correlation r = -0.462). In standing on two legs, no sway test results showed a significant correlation to MMSE scores with EO. With EC, the magnitude of sway became greater, and was significantly correlated to MMSE scores in the head distance.
Although the correlation between head sway and MMSE was not strong, head sway showed a stronger correlation than did foot pressure sway. Standing on one leg, as measured by head sway area, may thus predict cognitive impairment.
神经功能或平衡功能障碍对认知障碍的影响尚未得到充分研究。我们将通过头部或足部摆动测量的平衡测试结果（以考虑全身摆动）与认知障碍测试结果进行了比较。
60岁以上的男女个体进行了30秒的平衡测试。我们测量了单腿或双腿站立时的摆动情况。通过头部或足部压力的移动距离或面积来评估摆动。我们还评估了视觉条件的影响：睁眼（EO）或闭眼（EC）。使用简易精神状态检查表（MMSE）来评估认知障碍的程度。
单腿站立时的头部摆动面积与睁眼时的MMSE评分显著相关（相关系数r = -0.462）。双腿站立时，没有摆动测试结果与睁眼时的MMSE评分显示出显著相关性。闭眼时，摆动幅度变大，并且与头部距离的MMSE评分显著相关。
尽管头部摆动与MMSE之间的相关性不强，但头部摆动显示出比足部压力摆动更强的相关性。因此，通过头部摆动面积测量的单腿站立可能预测认知障碍。
