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 without LBP during gait. The aim this study was to compare gait parameters as well combined motions using the kinematic similarity index (KSI) LBP. Twenty-two 19 age- body mass index-matched control participated in study. cycle were compared those prototype derived from healthy subjects. calculations resulted response vectors that analyzed comparison control-derived for normalized at 5% increments cycle. results our indicated KSI group demonstrated higher swing (t = 4.23, p 0.001) stance 6.26, phases group. whole significantly different groups 6.52, 0.001), especially midstance phases. could have adjusted patterns these specific useful clinical outcome measures differentiate changes demonstrate quantified It warranted validate analysis physiological asymmetry larger sample future studies.
