目的 研究2型糖尿病患者前行和倒走时的足底压力变化,探索倒走可能存在的意义.方法 选取2011年6月至2012年5月在北京军区总医院内分泌科门诊和病房就诊的114例2型糖尿病患者,男58例,女66例,年龄(53±11)岁.同期检测健康体检者83名,男40名,女43名,年龄(51±13)岁.采用足底压力测试与分析系统将足底分为10个区域,通过测定前行和倒走时两组足底峰值压力和冲量,了解足底压力分布特点.采用两样本独立t检验进行统计学分析.结果 (1)前行时:与对照组相比,糖尿病组在第1、3跖骨(M1、M3)、足跟内侧(HM)区域足底峰值压力均升高,以M3区为最高[左足:对照组为(16.5±2.0)N/cm2,糖尿病组为(21.9±5.0)N/cm2；右足:对照组为(18.2 ±2.8)N/cm2,糖尿病组为(19.4±4.4)N/cm2,差异有统计学意义(t=-10.46、-2.31,均P＜0.05)].(2)前行时:与对照组相比,糖尿病组在第1趾(T1)、第1～5跖骨(M1～M5)、足中部或足弓(MF)、HM、足跟外侧(HL)区双足的冲量升高,以M3区升高最明显[左足:对照组为(50±11)N·s,糖尿病组为(87 ±21)N·s,右足:(62±15)比(84±19)N·s,t=-16.24、-8.60,均P＜0.05].(3)与前行时相比,倒走时糖尿病组患者在T1、第2～5趾(T2-5)、M1、MF、HM、HL区峰值压力均有不同程度的增大,而在M3区峰值压力却显著减小[左足分别为(22 ±5)、(12±5)N/cm2,右足分别为(19±4)、(15 ±6) N/cm2,t=15.10、5.61,均P＜0.05].(4)与前行时相比,糖尿病组倒走时双足T1、T2-5区的冲量增大,以T1区明显[左足分别为(54±18)、(81±16) N·s,右足分别为(29±11)、(75 ±18)N·s,t=-11.85、-23.90,均P＜0.05]；而双足M2、M3、M4区的冲量小于前行时同样部位的冲量,以M3区尤为显著[左足分别为(87 ±21)、(61±18) N·s,右足分别为(84±19)、(59±18) N·s,t=9.82、-9.63,均P＜0.05].结论 糖尿病患者前行时足底峰值压力、冲量分布与正常人相比存在异常,而倒走可明显改善其足底受力情况,缓解前足受力.

Objective To observe the plantar pressure distribution of type 2 diabetic patients in forward walking and backward walking,explore the significance of backwarding that may exit.Methods A total of 114 patients with type 2 diabetes (DM group,male 58,female 66 cases,age (53 ± 11) yrs) were recruited from June 2011 to May 2012.Eighty-three healthy people (DC group,male 40,female 43 cases,age (51 ± 13)yrs) were compared during the same period.The plantar pressure distribution was measured by foot peak pressure and impulse in the forward walking and backward walking.Two-sample t test was used for statistical analysis.Results (1) Forward walking:compared with the control group,the peak foot pressure in the metatarsal 1,3 (M1,M3),heel medial (HM) were increased in the diabetic group.The highest pressure was at M3 (left foot:the control group (16.5 ± 2.0) N/cm2,diabetic group (21.9 ± 5.0) N/cm2 ;right foot:the control group (18.2 ±2.8) N/cm2,diabetic group (19.4 ±4.4) N/cm2,the difference was statistically significant (t =-10.46,-2.31,both P ＜ 0.05)).(2) Forward walking:compared with control group,the impulse increased in the toe 1 (T1),metatarsal 1 to 5 (M1 to M5),foot central arch or mid foot(MF),heel medial(HM) and heel lateral(HL) in diabetic group,especially in the M3 area (left foot:(50 ± 11) N · s in the control group,(87 ± 21) N · s in the diabetic group ; right foot:the control group(62±15)N·s,diabetic group (84±19)N · s,t=-16.24,-8.60,both P＜0.05).(3) Compared with forward walking,the peak pressure at T1,toe 2-5(T2-5),M1,MF,HM and HL had different degrees of increase in the diabetic patients with backward walking,but the peak pressure was significantly reduced in M3 (left foot were (22 ±5),(12 ±5) N/cm2,right foot were (19 ±4),(15 ±6) N/cm2,t =15.10,5.61,both P ＜0.05).(4) Compared with forward walking,the impulse was increased in T1 and T2-5 areas in the diabetic group with backward walking,especially in T1 zone(left foot:(54 ± 18),(81 ± 16) N · s,right foot:(29 ± 11),(75 ± 18) N · s,t =-11.85,-23.90,both P ＜ 0.05) ; but the impulse at M2,M3,M4 was less than the same parts of impulse at the forward walking,especially in M3 zone(left foot:(87 ±21),(61 ±18) N· s,right foot:(84±19),(59±18) N · s,t=9.82,-9.63,both P＜0.05).Conclusions Compared with normal subjects,the plantar peak pressure and impulse distribution in patients with diabetes are different.Backward walking may improves the plantar pressure distribution of diabetic patients.
