Biomechanical analysis of walk in healthy individuals and individuals affected by the lower back pain syndrome - a preliminary study

Introduction: The lower back pain syndrome (LBS) is a chronic health problem that compromises physical function, and especially affects the walk. The goal of this study was to analyze the kinetic and kinematic parameters of pace in healthy people and people affected with LBS. Material and Methods: In the group of 20 patients with LBS kinematic data of the walk were collected using three-dimensional motion analysis system with eight video cameras of 100Hz and two cameras of 30Hz. Kinetic data were collected with one platform force (1000 Hz). The same measurements were provided on 10 healthy people of the control group. Respondents with LBP filled the standardized questionnaires for pain and disablement (Roland Morris and Oswestry Disability Index Questionnaires). Results: The average walking speed was significantly lower, the step length was significantly shorter and vertical ground reaction force was significantly lower in the patients group than in control group. The results obtained with the Oswestry index in the patients group significantly positive correlated with the stance time and swing time of the right leg while on the left side no statistically significant correlations were observed. Conclusions: LBS affects quality of walk in all spatio-temporal parameters. Moreover, the left and right legs are unequally affected during the walk in patients with LBS. These results give us a basis for future studies regarding the effectiveness of various invasive and noninvasive therapeutic procedures in patients with LBS.
