摘  要:目的 探讨遗忘型轻度认知功能障碍(amnestic mild cognitive impairment,aMCI)和轻中度阿尔茨海默(Alzheimer's disease,AD)患者的平衡功能变化,以及人体姿势平衡仪在鉴别aMCI、轻中度AD以及健康人群中的应用价值.方法 应用人体姿势平衡仪对20例aMCI和20例轻中度AD患者的平衡功能进行测试,并选取20名年龄性别相匹配的健康体检者作为对照.结果 轻中度AD患者的所有平衡仪检测指标均与健康对照有显著差异,其中AD组支撑面积(15 398±926)mm2,睁眼状态时X轴平均位移(Mean X,10.2±4.1)mm、Y轴平均位移(Mean Y,-29.8±10.2)mm、X轴最大值(Max X,30.5±9.5)mm、Y轴最大值(Max Y,42.7±11.4)mm、姿势图长度(LSKG,528.4±105.4)mm、姿势图面积(SSKG,252.5±89.7)mm2,闭眼状态时Mean X(13.1±4.5)mm、Mean Y(-58.2±16.9)mm、Max X(37.7±10.5)mm、Max Y(78.5±18.7)mm、LSKG(816.6±171.3)mm、SSKG(649.0±129.7)mm2,与健康对照组各指标[支撑面积(31 654±2132)mm2,睁眼状态时分别为(5.8±1.4)mm、(-14.9±4.4)mm、(18.3±4.1)mm、(23.3±6.8)mm、(390.3±68.4)mm、(178.8±40.9)mm2;闭眼状态时(7.9±1.5)mm、(-25.6±5.4)mm、(24.7±7.3)mm、(39.9±9.9)mm、(533.5±97.4)mm、(290.5±73.3)mm2]比较差异均有统计学意义(支撑面积t=8.57,睁眼状态时F值分别为17.41、38.10、60.46、102.10、29.31、27.85,闭眼状态时F值分别为37.20、541.79、34.51、185.56、122.83、384.27,均P<0.05);支撑面积和Mean Y在aMCI组[(23 921±1637)mm2,(-39.8±8.6)mm]和健康对照组[(31 654±2132)mm2,(-25.6±5.4)mm]之间差异有统计学意义(t=6.50,P=0.038;t=-15.34,P=0.012).结论 轻中度AD及aMCI患者均存在平衡功能障碍,人体姿势平衡仪检测对临床上运动表现和平衡能力均在正常范围的aMCI、轻中度AD以及健康人群具有鉴别意义.Objective To investigate alterations of balance function in patients with mild-moderate Alzheimer's disease (AD) and with amnestic mild cognitive impairment (aMCI),and the possibility of using posturography to differentiate aMCI,mild-moderate AD and normal subjects. Methods The balance function of 20 patients with mild-moderate AD and 20 patients with aMCI were evaluated by posturography,and 20 healthy subjects of the same age range were recruited as controls.Results All posturography measures were significantly altered in mild-moderate AD patients compared with normal controls,with limits of stability( ( 15 398 ± 926 ) mm2 vs ( 31 654 ± 2132 ) mm2 ),open-eyed Mean X ( ( 10. 2 ± 4. 1 ) mm vs (5.8 ± 1. 4)mm) ,Mean Y(( -29.8 ± 10.2)mm vs ( -14.9 ±4.4) mm),Max X((30.5 ±9.5)mm vs (18.3 ±4. 1)mm ),Max Y((42.7 ± 11.4)mm vs (23.3 ±6.8)mm),LSKG((528.4 ± 105.4)mm vs (390. 3 ± 68.4 ) mm ),SSKG ( ( 252. 5 ± 89. 7 ) mm2 vs ( 178.8 ± 40. 9 ) mm2 ),close-eyed Mean X ((13. 1 ±4. 5) mm vs (7.9 ± 1.5)mm) ,Mean Y (( -58.2 ± 16. 9) mm vs ( -25.6 ±5.4) mm) ,Max X ((37.7±10.5)mm vs (24.7 ±7.3) mm ),Max Y ((78.5±18.7)mm vs (39.9 ±9.9) mm),LSKG ((816.6±171.3) mm vs (533.5 ±97.4) mm),SSKG((649.0 ± 129.7) mm2 vs (290.5 ±73.3) mm2),respectively ( t = 8.57; open-eyed F = 17.41,38. 10,60. 46,102. 10,29. 31,27. 85; close-eyed F = 37.20,541.79,34. 51,185.56,122. 83,384. 27 ;all P <0. 05) ;limits of stability ( (23 921 ± 1637 )mm2 vs (31 654 ±2132 ) mm2 ) and mean Y ( Antero-posterior sway,( - 39. 8 ± 8. 6 ) mm vs ( - 25.6±5.4 ) mm) were the only parameters which discriminated between aMCI and normal controls,respectively ( t = 6. 50,P = 0. 038; t =- 15.34,P = 0. 012). Conclusions Impairment in balance is a feature not only of mild-moderate AD,but also of aMCI,and posturography may be used as a possible test in differ
