To determine the effect of using a walking aid on temporal and spatial parameters of gait when used for balance versus support on the dominant and nondominant hand side.
Repeated measures observational study design.
University gymnasium.
Twenty-seven healthy male and female adults of mean ± standard deviation age 44.74 ± 10.00 years.
Five walking conditions (C) were completed by all participants on the GAITRite pressure mat. Normal walking (C1), walking with a cane in the dominant hand (C2) and nondominant hand (C3) as if using for balance, walking with a cane in the dominant hand (C4) and nondominant hand (C5) while allowing approximately 10% of the body weight through the cane.
Temporal measurements (swing time, stance time, single limb support time, double limb support time) as percentage of a gait cycle and the base of support for the left and the right foot for all 5 walking conditions.
A significant difference (P < .001) was observed between C1, C2, and C3 in percentage swing time and percentage stance time of the ipsilateral side, and in percentage single limb support time of the contralateral side. The double limb support time was significantly different (P ≤ .04) for both ipsilateral and contralateral sides. Comparisons among C1, C4, and C5 demonstrated significance (P < .001) for all variables. Post hoc analysis showed significance between C1 and C4, and C1 and C5 for all variables except percentage stance time of the ipsilateral side and percentage single limb support of the contralateral side.
In healthy adults, use of a cane for balance modifies swing and stance parameters of the ipsilateral side and does not affect the base of support formed by the feet. When used for support, the cane alters the swing and stance parameters, and also the base of support formed by the feet.
确定使用助行器用于平衡与在优势手侧和非优势手侧用于支撑时对步态的时间和空间参数的影响。
重复测量观察性研究设计。
大学体育馆。
27名健康成年男女，平均年龄±标准差为44.74±10.00岁。
所有参与者在GAITRite压力垫上完成五种行走条件（C）。正常行走（C1），优势手持手杖行走（C2）和非优势手持手杖行走（C3），仿佛用于平衡，优势手持手杖行走（C4）和非优势手持手杖行走（C5），同时允许约10%的体重通过手杖。
五种行走条件下，摆动时间、站立时间、单腿支撑时间、双腿支撑时间占步态周期的百分比，以及左右脚的支撑基底。
在同侧的摆动时间百分比和站立时间百分比，以及对侧的单腿支撑时间百分比方面，C1、C2和C3之间观察到显著差异（P < .001）。同侧和对侧的双腿支撑时间均有显著差异（P≤.04）。C1、C4和C5之间的所有变量比较均显示出显著性（P < .001）。事后分析显示，除同侧站立时间百分比和对侧单腿支撑百分比外，C1与C4以及C1与C5之间的所有变量均有显著性差异。
在健康成年人中，使用手杖进行平衡会改变同侧的摆动和站立参数，且不影响双脚形成的支撑基底。当用于支撑时，手杖会改变摆动和站立参数，以及双脚形成的支撑基底。
