Spinal stenosis is defined as neurogenic claudication due to
narrowing of the spinal canal lumen diameter. As the disease progresses,
ambulation and gait may be impaired. Self-report measures are routinely used in
the clinical setting to capture data related to lumbar pain symptoms, function
and perceived disability. The associations between self-report measures and
objective measures of physical function in patients with lumbar spinal stenosis
are not well characterized. The purpose of this study was to determine the
correlation between self-reported assessments of function with objective
biomechanical measures of function. METHODS: 25 subjects were enrolled in this
study. Subjects completed self-report questionnaires and biomechanical
assessments of gait analysis, lumbar 3D ROM and lumbar proprioception.
Correlations were determined between self-report measures and biomechanical data.
RESULTS: The Oswestry Disability Index (ODI) was strongly correlated with stride
length and gait velocity and weakly correlated with base of support. ODI was also
weakly correlated with left lateral bending proprioception but not right lateral
bending. The SF12 was not significantly correlated with any of the biomechanical
measurements. Pain scores were weakly correlated with velocity, and base of
support, and had no correlation any of the other biomechanical measures.
DISCUSSION: There is a strong correlation between gait parameters and functional
disability as measured with the ODI. Quantified gait analysis can be a useful
tool to evaluate patients with lumbar spinal stenosis and to assess the outcomes
of treatments on this group of patients.
