摘要:

文题释义:

RSSCAN步态系统:由RSSCAN International公司生产的步态测试与分析系统,配有一个长2 m、宽0.4 m且内含16 384个压力感受器的步道压力测试平板,与电脑信息采集端软件相连,能够实时动态地采集受试者在测试平板上步行时的时-空参数(包括步速、支撑时相、摆动时相、步态周期、步长、步幅、步宽、足轴角)及生物力学相关参数(包括压力参数、压强参数、足底冲量和足底接触面积)等。
偏瘫步态:是脑卒中患者常见后遗症之一。由于机体运动系统失去高位中枢神经调控,原始的、被抑制的皮质下中枢运动反射释放,导致肢体肌群间协调功能紊乱、肌张力异常等而出现运动功能障碍。典型的偏瘫步态表现为患足摆动时足下垂、内翻、髋关节外展外旋的划圈样步态。

背景:量化脑梗死偏瘫患者步态特征能够作为其后期康复治疗的重要参考依据,而RSSCAN步态系统能够实时定量地采集受试者行走时的步态参数。
目的:探究脑梗死偏瘫患者的步态特征及健、患侧足之间的步态差异。
方法:纳入北京中医药大学东直门医院与北京中医医院怀柔医院收治的脑梗死偏瘫患者134例,其中男102例,女32例,年龄(60±9)岁。通过RSSCAN步态系统采集受试者步行时的步态参数,选取中间段测试中两对步态周期连续的清晰足印,并将受试者双侧足底手动分成十分区(第1趾区、第2-5趾区、第1跖骨区、第2跖骨区、第3跖骨区、第4跖骨区、第5跖骨区、中足区、足跟内侧区、足跟外侧区),获取偏瘫患者步态时-空参数及生物力学相关参数进行分析。

结果与结论:①步态时-空参数:健侧足支撑时间大于患足(P < 0.01),患侧足摆动时间、步长均大于健足(P < 0.05);Pearson或Spearman秩相关分析表明,健侧足与患侧足的支撑时间、步态周期、步长、步宽、步幅具有显著正相关关系(P < 0.01);②生物力学相关参数:与患侧足相比,健侧足在第1趾区、第2-5趾区、第1跖骨区的最大压力、最大压强、足冲量增大(P < 0.05),足跟外侧区的最大压力增大(P < 0.05),足跟内侧区、足跟外侧区的足冲量增加(P < 0.01),第2-5趾区、中足区的足底接触面积增加(P < 0.05);Pearson或Spearman秩相关分析表明,健侧足与患侧足在足底十分区的最大压力、最大压强和足冲量值均具有显著正相关关系(P < 0.01),在第2-5趾区、第1跖骨区、第2跖骨区、第3跖骨区、第4跖骨区、中足区、足跟内侧区、足跟外侧区的足底接触面积具有显著正相关关系(P ≤ 0.01);③脑梗死偏瘫患者步态特征主要体现在:从时间参数上看,健足承担主要代偿作用;从空间参数方面上看,为维持步行的稳定性,与患侧足对比,健侧足表现更为保守;生物力学方面:为弥补患侧足向前推力的不足,健侧足前足区受力增加,这种不对称受力的代偿模式可能不利于步行能力的恢复。

Abstract: BACKGROUND: Quantifying the gait features of hemiplegic patients with cerebral infarction can be used as an important reference for their rehabilitation, and the RSSCAN gait system can collect gait parameters quantitatively and timely during walking.
OBJECTIVE: To explore the gait characteristics of hemiplegic patients with cerebral infarction and the difference between affected and unaffected feet.
METHODS: A total of 134 hemiplegic patients with cerebral infarction were selected, including 102 males and 32 females, aged (60±9) years. The gait parameters were collected by the RSSCAN gait system when the patients walked. Clear footprints of the two continually gait cycles of mid-gaits were selected, meanwhile each foot was manually divided into 10 plantar regions: the first toe, the second to fifth toes, the first to fifth metatarsals, the midfoot, the medial heel, and the lateral heel. Then the temporo-spatial parameters and biomechanical parameters were analyzed.
RESULTS AND CONCLUSION: Temporo-spatial gait parameters: compared with the unaffected foot, the affected foot showed shorter stance phase time (P < 0.01) and longer swing phase time and step length (P < 0.05). Pearson or Spearman rank correlation analysis showed that the stance phase time, gait cycle, step length, stride width, and stride were significantly positively correlated between the affected and unaffected feet (P < 0.01). Biomechanical parameters: Compared with the affected foot, the maximum force, maximum pressure and plantar impulse of the healthy foot increased in the first toe, the second to fifth toes and the first metatarsal (P < 0.05), the maximum force in the lateral heel area increased (P < 0.05), the plantar impulse in the medial and lateral heel areas increased (P < 0.01), and the plantar contact area of the second to fifth toes and the midfoot increased (P < 0.05). Pearson or Spearman rank correlation analysis showed that there was a significant positive correlation between the maximum force, maximum pressure and plantar impulse in the 10 plantar regions of the unaffected foot and the affected foot (P < 0.01); and there was a significant positive correlation between the plantar contact area of the second to fifth toes, the first metatarsal, the 2nd metatarsal, the 3rd metatarsal, the 4th metatarsal, the midfoot, the medial heel, and the lateral heel of the unaffected foot and the affected foot (P ≤ 0.01). The gait characteristics of hemiplegic patients with cerebral infarction: in terms of temporal parameters, the unaffected foot plays the main compensatory role; in terms of spatial parameters, the unaffected foot is more conservative than the affected foot to maintain the stability of walking; in terms of biomechanical parameters, the force in the forefoot area of the unaffected foot increases to compensate for the lack of forward propulsion of the affected foot. This compensatory mode of asymmetric force may not be conducive to the recovery of walking ability.
