摘要
目的:观察和分析糖尿病周围神经病变(DN)患者足底压力分布对糖尿病足溃疡(DFU)的影响。方法收集2014年7月至2015年6月在北京军区总医院内分泌科住院的2型糖尿病患者共119例,分为单纯糖尿病(DC)组42例,不伴有足溃疡病史的糖尿病周围神经病变(DN)组45例和过去1年内发生过足溃疡的DFU组32例,同时选取同期在我院常规体检者46名作为对照(CG)组。采用Foot-scan7平板式足底压力测试系统测试并分析上述受试者正常行走状态下的足底压力分布特点。多组间均数比较采用方差分析,两两比较采用LSD-t检验。结果(1)4组的足底压力随时间的变化趋势均呈明显的“双峰夹一谷”趋势(“M”型),DN组峰-谷压差高于CG组;DFU组峰-谷压差高于CG组及DC组[分别为(38±16)比(26±8)N/cm2,t=5.389;(41±16)比(26±8)N/cm2,t=2.964,P〈0.05;(41±16)比(32±12)N/cm2,t=4.070,均P〈0.05]。(2)CG组、DC组、DN组、DFU组双足底跖骨区(除M2外)及足中部(MF)峰值压逐渐升高,其中以M3区增高最为明显[右足底:(34±11)、(35±9)、(37±14)、(48±23)N/cm2,F=10.431,P〈0.05;左足底:(32±8)、(37±12)、(42±18)、(46±17)N/cm2,F=8.659,P〈0.05];而足跟内侧(HM)峰值压逐渐降低[右足底:(33±16)、(29±10)、(28±6)、(26±7)N/cm2,F=3.878, P〈0.05;左足底:(30±8)、(28±6)、(27±11)、(24±8)N/cm2,F=3.317,P〈0.05]。结论糖尿病周围神经病变患者足底局部区域峰值压异常升高,可能导致糖尿病足溃疡的发生。
Objective To investigate the impact of a previous history of foot ulcers on the plantar pressure distribution in diabetic neuropathy patients. Methods A total of 119 patients with type 2 diabetes were selected.According to TCSS scores and history of foot ulcers they were divided into diabetic control group(DC), diabetic neuropathy group(DN) and diabetic ulcers group(DFU), at the same time 46 nomal persons were selected as control group(CG). Spatiotemporal parameters of gait were assessed during level barefoot walking using Foot-scan7. Results (1)The plantar pressure-time curve of the four groups showed obvious“M”type.DN group showed higher peak-valley plantar pressure difference than CG group((38±16)vs (26 ± 8) N/cm2, t=5.389, P〈0.05).DFU group showed higher peak-valley plantar pressure difference than CG ((41±16)vs(26±8) N/cm2, t=2.964, P〈0.05) and DC group((41±16)vs(32±12) N/cm2, t=4.070, P〈0.05).(2) The peak plantar pressure of CG group, DC group, DN group, DFU grouprose successively at M1, M3-5 and MF, especially at M3(right foot:(34±11), (35±9), (37±14), (49±23) N/cm2, F=10.431, P〈0.05, leftfoot:(32±8), (37±12), (42±18), (46±17) N/cm2, F=8.659, P〈0.05). While at HM area, the peak plantar pressure of the four groups decreased successively(right foot:(33±16), (29±10), (28±6), (26±7)N/cm2, F=3.878, P〈0.05, left foot:(30 ± 8), (28 ± 6), (27 ± 11), (24 ± 8) N/cm2, F=3.317, P〈0.05). Conclusion Diabetic peripheral neuropathy patients presented higher plantar pressure in some local area, leading to the occurence of foot ulcers.
