Stance Phase Characteristics and Asymmetry in Females with Low Back Pain

Abstract

Background:This study aimed to investigate stance phase characteristics and asymmetry in females with non-specific low back pain (LBPP) which they adopt different strategies in walking to reduce pain and enhance walking quality. The results of this research can provide new insight into gait characteristics for individuals with LBPP by examining temporal characteristics and asymmetry in their stance phase during walking. Method: In this cross-sectional study, 36 females were purposefully recruited and divided into two groups: one consisting of 18 individuals with low back pain (LBPP) and the other without LBPP. Data were collected using the Footscan system and analyzed with the Footscan Gait 7 gait generation software. Independent t-tests were employed to compare the outcomes between the two groups. Results: The results indicated that the right (p=0.001) and left (p=0.001) foot progression angles in the low back pain group were higher than those in the healthy group. Additionally, the low back pain group exhibited higher asymmetry in the timings of the initial contact phase (p=0.02) and forefoot contact phase (p=0.02), as well as in foot progression angle asymmetry (p=0.009) compared to the healthy group. Conclusion:Given the higher foot progression angle and observed asymmetries in individuals with low back pain, rehabilitative exercises need to consider these differences when evaluating and planning rehabilitation procedures.
