effects of mechanical low back pain in spatiotemporal parameters of gait

Background: mechanical low back pain is one of the most common complaints of people, which may interfere with some aspects of daily living activity such as walking. objectives: the aim of the present study was to objectively assess the effects of mechanical low back pain on the gait pattern. methods: thirty mechanical low back pain patients and 30 healthy subjects were recruited randomly (age 18 - 60). the spatiotempo- ral parameters of gait were assessed and recorded as subjects walked on a two-meter platform three times at their normal walking speed. descriptive statistical methods were used to evaluate demographic characteristics. the independent samples t-test was used to compare the groups for the gait parameters. results: no significant differences were found between controls and patients in demographic variables. significant differences were obtained between patients and healthy subjects in step length (p < 0.04), step time (0.009), single support time (0.04), stride length (0.04), stride time (0.01), velocity (0.03), and cadence (0.009). conclusions: the results of this study showed mechanical low back pain has a great influence on the spatiotemporal parameters of gait. the findings can be used in selecting better rehabilitation procedures.
