This study was aimed at investigating the changes in the degree of weight support loaded on the cane and paretic-side lower limb muscle activation according to the types of cane and cane-supported gait using a weight-support feedback cane (WSFC). Eleven hemiparetic stroke patients were recruited from a local rehabilitation hospital. WSFC can measure the degree of weight support loaded on the cane during cane-supported walking in units of kg, through a force sensor installed inside the handle. This study measured the degree of weight support loaded on the cane and lower limb muscle activation under four conditions: two-point and three-point gait with mono and quadripod canes. In the two-point gait with mono and quadripod canes, subjects were asked to move the WSFC and paretic-side foot forward at the same time and then move the nonparetic-side foot. In the three-point gait with mono and quadripod canes, subjects were asked to first move the WSFC forward, then the paretic-side foot, and finally the nonparetic-side foot. The degree of weight support loaded on the cane was significantly higher in the three-point gait with WSFC than in the two-point gait with WSFC for both mono () and quadripod canes (). Additionally, the paretic-side lower limb muscle activation during the stance phase was significantly higher in the two-point gait with WSFC than in the three-point gait with WSFC for both mono () and quadripod canes (). Our results suggest that applying the three-point gait with high cane dependence in the early stages of training for stability and subsequently applying the two-point gait for the enhancement of lower limb muscle activation and training of normal gait pattern could be effective.

下肢中风患者下肢肌肉激活和体重支持程度的变化，取决于手杖支撑步态的类型

这项研究的目的是研究使用体重支持反馈手杖（WSFC）根据手杖和手杖支撑步态的类型，对手杖上支撑重量的程度和下肢侧下肢肌肉的激活进行变化。从当地一家康复医院招募了11名中风偏瘫患者。WSFC可以通过安装在手柄内的力传感器来测量以手为单位的手杖支撑行走过程中手杖上的重量支撑程度。这项研究测量了在四种条件下单脚和四脚手杖的两点和三点步态对手杖负重的支持程度和下肢肌肉的激活程度。在单脚和四脚手杖的两点步态中，受试者被要求同时向前移动WSFC和and侧脚，然后再移动the侧脚。在具有单脚和四脚手杖的三点步态中，要求受试者首先使WSFC向前移动，然后再使par侧的脚向前移动，最后使非par侧的脚向前移动。WSFC的三点步态比单点WSFC的两点步态在手杖上的承重程度要高得多）和四脚手杖（）。此外，对于WSFC而言，在站立阶段阶段的坐骨侧下肢肌肉激活明显高于WSFC的三点步态，而单点（）和四脚手杖（）。我们的结果表明，在稳定性训练的早期阶段应用具有高拐杖依赖性的三点步态，然后再应用两点步态来增强下肢肌肉的激活和正常步态模式的训练。
