Background

Peroneus longus and brevis (PLB) disorders are commonly in people with lateral ligamentous instability, ankle pain, lateral hindfoot pain and structures of the proximal compartment of the lower legs and their muscle activity is believed to be influenced by different footwear types. The proposal of this research is to evaluate the effects of five types of footwear with respect to the barefoot condition and analyze the activity patterns of PLB muscles in healthy subjects during the gait cycle.

Methods

Thirty healthy subjects were recruited in a laboratory in this cross-sectional research design. While walking, electromyography (EMG) activity was measured from PLB via surface electrodes in six experimental conditions: 1) barefoot, 2) minimalist, 3) pronated control, 4) air chamber, 5) ethyl-vinyl-acetate (EVA) and 6) boost. These data were obtained and compared.

Results

The peroneus brevis showed significant reductions in the peak amplitude of the five footwear types (minimalist, pronation control, air chamber, EVA and boost) with respect to the barefoot condition in the propulsion phase of the gait cycle during walking (P = 0.034; P < 0.001; P < 0.001; P < 0.001; P = 0.006) and running (P = 0.004; P < 0.001; P = 0.001; P < 0.001; P = 0.001), respectively. Furthermore, peroneus longus showed significant reductions in the peak amplitude of these five footwear types with respect to the barefoot condition in the propulsion phase of the gait cycle during running (P = 0.005; P = 0.038; P = 0.019; P = 0.025; P = 0.021).

Conclusion

The EMG activity patterns of the PLB muscles may depend on the use of different types of sport shoes such as minimalist, pronation control, air chamber, EVA and boost footwear with respect the barefoot condition in different phases of the gait cycle during walking and running.

肌电图比较各种鞋类对腓骨长肌和短肌的活动模式的影响

背景

腓骨长短肌（PLB）疾病通常发生在韧带外侧韧带不稳，踝关节疼痛，后足外侧疼痛和小腿近端隔室结构的人群中，其肌肉活动受不同鞋类的影响。这项研究的建议是评估五种鞋类对赤脚状况的影响，并分析步态周期中健康受试者的PLB肌肉活动模式。

方法

在该横断面研究设计中，实验室招募了30名健康受试者。行走时，在6个实验条件下通过表面电极从PLB测量肌电图（EMG）活性：1）赤脚，2）极简主义，3）带齿的对照，4）气室，5）乙基醋酸乙烯酯（EVA）和6 ） 促进。获得并比较了这些数据。

结果

在步行步态周期的推进阶段，相对于赤脚状况，腓骨短肌在五种鞋类（极简，前旋控制，气室，EVA和助力）的峰值振幅上均显着降低（P  = 0.034；P  <0.001; P  <0.001; P  <0.001; P  = 0.006）并运行（P  = 0.004; P  <0.001; P  = 0.001; P  <0.001; P = 0.001）。此外，在跑步过程中，步态周期的推进阶段，相对于赤脚状况，腓骨长直肌的峰值幅度显着降低（P  = 0.005；P  = 0.038；P  = 0.019；P  = 0.025；P  = 0.021）。

结论

PLB肌肉的EMG活动模式可能取决于使用不同类型的运动鞋，例如在步行和跑步过程中步态周期不同阶段的赤脚状态下使用的极简，旋前控制，气室，EVA和增高鞋类。
