Ankle sprain are one of the most common injuries in sports and public health in general. Cross-slope may creat a risk for ankle sprain and are commonly found in both urban and rural environment.
The purpose of study was to clarify the environmental risk factor that can be easily occurred ankle sprain during walking (stance phase) and one leg standing at various ramp environment.
Participants was measured muscle activation on peroneus longus during both conditions (walk across the ramp and one leg stand in the transverse direction) of seven different angle (0∘, 2∘, 5∘, 10∘, 15∘, 20∘, 25∘). The measured data were analyzed using one-way ANOVA to investigate the effect of muscle activation on the each condition.
Ankle sprain can be easily occurred when cross walk and one-leg stand on a ramp from higher than 10∘, and highest risk was angle of 25∘ or more. As a people with peroneus longus weakness walks a ramp, the ramp angle has a cross relationship with the sprain on the ankle.
If people with peroneus longus weakness walk on the more than 10∘ of ramp angle, they will need a lot of attention for prevent ankle sprain.
踝关节扭伤是体育活动和一般公共卫生中最常见的损伤之一。斜坡可能会造成踝关节扭伤的风险，在城市和农村环境中都很常见。
本研究的目的是明确在不同斜坡环境下行走（站立阶段）和单腿站立时容易发生踝关节扭伤的环境危险因素。
在七种不同角度（0°、2°、5°、10°、15°、20°、25°）的两种情况下（穿过斜坡行走和横向单腿站立）测量参与者腓骨长肌的肌肉激活情况。使用单因素方差分析对测量数据进行分析，以研究每种情况下肌肉激活的影响。
当在高于10°的斜坡上横向行走和单腿站立时，踝关节容易发生扭伤，最高风险是25°及以上的角度。对于腓骨长肌较弱的人来说，在斜坡上行走时，斜坡角度与踝关节扭伤呈交叉关系。
腓骨长肌较弱的人如果在斜坡角度超过10°的地方行走，需要特别注意预防踝关节扭伤。
