Abstract

Background

The Heel Rise endurance (HRE) which indicates the extrinsic foot core (ECO) muscle’s performance and the paper grip endurance (PGE) which indicates the intrinsic foot core (ICO) muscle's performance are essential components of a healthy foot function. However, the foot core muscles’ fatigue response on spatial and temporal gait parameters after the HRE and the PGE tests were not adequately investigated. The purpose of this study was to determine whether the fatigue of the ICO and the ECO muscles affect gait parameters.

Material and methods

A prospective, cross-sectional study was conducted on 22 sedentary individuals (44 feet). Gait was investigated pre and after the Heel Rise (HR) endurance test and the paper grip (PG) endurance test by inertial sensors. At least 500 consecutive steps were collected for each individual. Spatial-temporal gait parameters were used as outcome measures.

Results

ECO fatigue and ICO fatigue led to increases in the step length (p < 0.05) and the stride lengths (p < 0.05), the single support (p < 0.05), and the terminal stance durations (p < 0.05). It was also seen that ICO fatigue had a greater effect on gait than ECO fatigue. The ECO fatigue had a medium to large effect on the gait parameters (d=0.313–0.646). The ICO fatigue affected gait with a large effect (d=0.524–2.048).

Conclusion

The ECO fatigue and the ICO fatigue led to clinically important changes in long-range gait parameters and the ICO fatigue had a greater effect on gait than ECO fatigue. It was suggested that clinicians add ICO muscle endurance training to improve the physical performance of individuals.

足部内在核心肌肉疲劳对步态的影响大于足部外在核心肌肉疲劳：基于时间序列的分析

背景表示足部外在核心肌肉（ECO）性能的 "足跟上升耐力"（HRE）和表示足部内在核心肌肉（ICO）性能的 "握纸耐力"（PGE）是健康足部功能的重要组成部分。然而，在ERE和PGE测试后，足核心肌肉对空间和时间步态参数的疲劳反应尚未得到充分研究。本研究的目的是确定 ICO 和 ECO 肌肉的疲劳是否会影响步态参数。通过惯性传感器对 "脚跟抬高（HR）耐力测试 "和 "握纸（PG）耐力测试 "前后的步态进行了调查。每个人至少连续走 500 步。结果ECO疲劳和ICO疲劳导致步长（p <0.05）、步幅（p <0.05）、单次支撑（p <0.05）和终端站立持续时间（p <0.05）增加。此外，ICO 疲劳比 ECO 疲劳对步态的影响更大。ECO 疲劳对步态参数的影响为中等到较大（d=0.313-0.646）。结论 ECO 疲劳和 ICO 疲劳会导致长程步态参数发生临床上重要的变化，ICO 疲劳对步态的影响大于 ECO 疲劳。建议临床医生增加 ICO 肌肉耐力训练，以改善个体的体能表现。

期刊介绍： The Foot is an international peer-reviewed journal covering all aspects of scientific approaches and medical and surgical treatment of the foot. The Foot aims to provide a multidisciplinary platform for all specialties involved in treating disorders of the foot. At present it is the only journal which provides this inter-disciplinary opportunity. Primary research papers cover a wide range of disorders of the foot and their treatment, including diabetes, vascular disease, neurological, dermatological and infectious conditions, sports injuries, biomechanics, bioengineering, orthoses and prostheses.
