Gait Asymmetry Comparison between Subjects with and without Nonspecific Chronic Low Back Pain

Individuals with chronic low back pain (LBP) report impaired somatosensory function and balance. However, there is a lack of investigation on limb motion similarities between subjects with and without LBP during gait. The aim of this study was to compare gait parameters as well as combined limb moti...

However, there is a lack of investigation on limb motion similarities between subjects with and without LBP during gait. The aim of this study was to compare gait parameters as well as combined limb motions using the kinematic similarity index (KSI) between subjects with and without LBP.

The results of our study indicated that the KSI of the control group demonstrated higher similarities in the swing (t = 4.23, <i>p</i> = 0.001) and stance (t = 6.26, <i>p</i> = 0.001) phases compared to the LBP group.

The LBP group could have adjusted the gait patterns during these specific phases. The KSI is useful for clinical outcome measures to differentiate kinematic changes and to demonstrate quantified similarities in the gait cycle between subjects with and without LBP. It is warranted to validate the KSI for the analysis of physiological gait asymmetry using a larger sample in future studies.Dongchul LeePaul SungMDPI AGarticlekinematic similarity indexnormalizationgait cyclelow back painasymmetryMathematicsQA1-939ENSymmetry, Vol 13, Iss 2129, p 2129 (2021)

However, there is a lack of investigation on limb motion similarities between subjects with and without LBP during gait. The aim of this study was to compare gait parameters as well as combined limb motions using the kinematic similarity index (KSI) between subjects with and without LBP.
