Abstract

OBJECTIVE

The present study was undertaken to assess whether footedness has effects on selected spatial and angular parameters of able-bodied gait by evaluating footprints of young adults.

SUBJECTS AND METHODS

A total of 112 males and 93 females were selected from among students and staff members of the University of Malawi using a simple random sampling method. Footedness of subjects was assessed by the Waterloo Footedness Questionnaire Revised. Gait at natural speed was recorded using the footprint method. The following spatial parameters of gait were derived from the inked footprint sequences of subjects: step and stride lengths, gait angle and base of gait. The anthropometric measurements taken were weight, height, leg and foot length, foot breadth, shoulder width, and hip and waist circumferences.

RESULTS

The prevalence of right-, left- and mix-footedness in the whole sample of young Malawian adults was 81%, 8.3% and 10.7%, respectively. One-way analysis of variance did not reveal a statistically significant difference between footedness categories in the mean values of anthropometric measurements (p > 0.05 for all variables). Gender differences in step and stride length values were not statistically significant. Correction of these variables for stature did not change the trend. Males had significantly broader steps than females. Normalized values of base of gait had similar gender difference. The group means of step length and normalized step length of the right and left feet were similar, for males and females. There was a significant side difference in the gait angle in both gender groups of volunteers with higher mean values on the left side compared to the right one (t = 2.64, p < 0.05 for males, and t = 2.78, p < 0.05 for females). One-way analysis of variance did not demonstrate significant difference between footedness categories in the mean values of step length, gait angle, bilateral differences in step length and gait angle, stride length, gait base and normalized gait variables of male and female volunteers (p > 0.05 for all variables).

CONCLUSIONS

The present study demonstrated that footedness does not affect spatial and angular parameters of walking gait.

摘要

目的

本研究旨在通过评估年轻成年人的足迹，来确定利足性是否会对健全人步态的特定空间和角度参数产生影响。

对象与方法

采用简单随机抽样法，从马拉维大学的学生和教职员工中选取了112名男性和93名女性。通过修订后的滑铁卢利足性问卷评估受试者的利足性。使用足迹法记录自然速度下的步态。从受试者的墨迹足迹序列中得出以下步态空间参数：步长和步幅、步态角度和步态基底。所进行的人体测量包括体重、身高、腿长和脚长、脚宽、肩宽以及臀围和腰围。

结果

在整个年轻马拉维成年人样本中，右利足、左利足和混合利足的比例分别为81%、8.3%和10.7%。单因素方差分析未显示利足性类别在人体测量平均值方面存在统计学显著差异（所有变量p>0.05）。步长和步幅值的性别差异无统计学意义。对这些变量进行身高校正并未改变趋势。男性步幅明显比女性宽。步态基底的标准化值存在类似的性别差异。男性和女性左右脚的步长和标准化步长的组均值相似。在两组志愿者中，步态角度存在显著的左右差异，左侧的均值高于右侧（男性t = 2.64，p < 0.05；女性t = 2.78，p < 0.05）。单因素方差分析未显示利足性类别在男性和女性志愿者的步长、步态角度、步长和步态角度的双侧差异、步幅、步态基底以及标准化步态变量的平均值方面存在显著差异（所有变量p>0.05）。
