Background and Aims: The current study aims to investigate the immediate effect of a researcher-made wedge treadmill on the activity of the selected lower limb muscles of flat feet individuals, so by activating the muscles, it can be used to help in the area of corrective exercise and correction of flat feet, rehabilitation and injury prevention.
Methods: The current study was a semi-experimental intervention based on the creation and introduction of a new tool and its effect evaluation. 16 subjects over 18 years old with flat feet deformity were included in this study. The subjects performed the protocol of walking at a normal speed on the researcher-made wedge treadmill at each of the lateral angles of 0, 5 and 15 degrees for 90 seconds. The electromyographic activity of five selected muscles was recorded at those angles. Statistical analysis was performed on Matlab and SPSS software. Friedman's test was used to evaluate the significant differences between angles and Bonferroni's post hoc test was used to compare two-by-two means.
Results: According to the results, the average activity of selected muscles (peroneus longus, tibialis anterior, gastrocnemius, soleus and hallucis longus) during walking between angles of 5 and 15 degrees on a wedge treadmill had a statistically significant difference compared to 0 degrees (P≤0.05).
Conclusion: This study showed that the amount of muscle activity of the lower limbs of subjects with flat feet during walking at 5 and 15-degree lateral angles has a significant difference compared to the same people walking at a zero-degree angle. Our results suggest that using the researcher-made wedge treadmill can significantly increase lower limb muscle activity in people with flat feet.
