摘要: 目的

通过足底压力分析脑卒中患者平衡调控机制。

方法

2019年7月至12月于本院康复科招募脑卒中受试者12例(脑卒中组)和正常人30例(对照组)。两组均进行睁、闭眼下的足底压力分析,比较运动学参数、动力学参数、足底压力中心(CoP)、相应对称性指数(SI)、对称性角度(SA)和Romberg商(RQ)。

结果

与睁眼状态比较,闭眼状态下,对照组平均Y和最大摆动明显增加(P < 0.01);脑卒中组球长度、平均速度和最大摆动均增大(P < 0.05)。与对照组比较,脑卒中组在睁、闭眼两种状态时均表现为椭圆面积显著增大(|t| > 3.509, P < 0.001),平均X变大(|Z| > 2.311, P < 0.05),而在闭眼状态时最大摆动明显增大(Z = -3.118, P < 0.01)。脑卒中组球长度RQ明显大于对照组(t = -3.570, P < 0.01)。两组在睁眼和闭眼两种状态下所有参数的SI和SA比较均无显著性差异(P > 0.05)。与对照组比较,脑卒中组在睁、闭眼两种状态时均表现为负荷SI、整体负荷SI、前足负荷SI、面积SI和前足面积SI均为负值变大(t > 2.344, P < 0.05),负荷SA、整体负荷SA、前足负荷SA、面积SA、前足面积SA增大(|t| > 2.297, P < 0.05),后足负荷SA仅在睁眼时增大(t = -2.485, P < 0.05),后足面积SA仅在闭眼时增大(t = -2.132, P < 0.05)。对照组在睁、闭眼两种状态下CoP主要分布在Y轴的负值方向,而脑卒中组CoP相对离散分布,在X轴上分布较对照组明显。

结论

脑卒中患者的平衡控制有赖于视觉补偿,且足底压力分析系统可有效评估脑卒中患者的平衡功能。

Abstract: Objective

To explore the mechanism of balance control after stroke by plantar pressure analysis.

Methods

From July to December, 2019, twelve stroke subjects (stroke group) and 30 normal subjects (control group) were recruited in the rehabilitation department of our hospital. Both groups were measured plantar pressure in eyes open and closed conditions. The kinematic parameters, dynamic parameters, plantar pressure center (CoP), symmetry index (SI), symmetry angle (SA) and Romberg quotient (RQ) were calculated.

Results

Compared with eyes open condition, the average Y and maximum swing of the control group increased significantly in eyes closed condition (P < 0.01); moreover, the ball length, average speed and maximum swing increased significantly in the stroke group (P <0.05). Compared with the control group, the area of the ellipse (|t| > 3.509, P < 0.001) and the average X (|Z|> 2.311, P < 0.05) significantly increased both in eyes open and closed condition, whereas the maximum swing (Z = -3.118, P < 0.01) increased significantly in eyes closed condition in the stroke group. The RQ of ball length was significantly more in the stroke group than in the control group (t = -3.570, P < 0.01). There was no significant difference in SI and SA of all parameters between the eyes open and closed condition in two groups (P > 0.05). Compared with the control group, load SI, overall load SI, forefoot load SI, area SI and forefoot area SI increased in both the eyes open and closed conditions in the stroke group (t > 2.344, P < 0.05), whereas load SA, overall load SA, forefoot load SA, area SA, forefoot area SA increased (|t|> 2.297, P < 0.05), hindfoot load SA increased only in eyes open condition (t = -2.485, P < 0.05), and hindfoot area SA increased only in eyes closed condition (t = -2.132, P < 0.05). In the control group, CoP was mainly distributed in the negative direction of Y axis when the eyes were open and closed, while CoP in the stroke group was relatively discrete, and the distribution on X axis was more obvious than that of the control group.

Conclusion

The balance control of stroke patients might depend on visual compensation, and the plantar pressure analysis system could be used to evaluate the balance function in stroke patients.
