Background and Objectives: Lower back pain is a common orthopedic illness that has a reasonable relationship to pronated foot. The aim of this study was to determine the effects of resistance training with Thera-Band on the electromyography frequency domain of trunk and lower limb muscles of patients with both low back pain and pronated feet during walking.
Materials and Methods: This clinical trial study was carried out at the University of Mohaghegh Ardebil in 2018. At first 30 men with low back pain and pronated feet were selected by convenience sampling and then randomly divided into control (n=15) and experimental (n=15) groups. An electromyographic system was used to record the activity of trunk and lower limb muscles during walking. Two-way ANOVA was used for statistical analysis.
Results: During the post-test phase compared with the pre-test phase in the experimental group, the median frequency of the tibialis anterior muscle (p=0.013) was lower during the loading response phase and the median frequency of the abdominal external oblique muscle (p=0.015) was larger during the loading response phase. In addition, during the post-test phase compared with the pre-test phase in the experimental group, the median frequency of the abdominal external oblique muscle (p=0.029) was higher during the push off phase. Also, during the loading response phase, the main effect of the group on the median frequency of biceps femoris (p=0.015) and erector spine (p=0.009) was statistically significant.
Conclusion: Considering the high activity of the tibialis anterior muscle in the patients with low back pain with pronated feet compared to the healthy subjects, there was a significant reduction in the median frequency of the tibialis anterior muscle during post-test compared with the pre-test during the loading response phase that shows the positive effects of this exercise protocol.
