OBJECTIVE: To determine relationships between increased signal intensity (ISI) on
T2-weighted cervical spine magnetic resonance imaging (MRI) and parameters of
gait analysis in patients with cervical spondylotic myelopathy (CSM). DESIGN: Retrospective comparative study. SETTING: Gait analysis laboratory. PARTICIPANTS:
Patients (N=36) who undertook cervical laminectomy or laminoplasty because of CSM. INTERVENTIONS: Not applicable. Subjects were
evaluated by using the modified Japanese Orthopaedic Association (JOA) scale, the
Nurick scale, cervical spine MRI, and gait analysis. Two radiologists classified
patients into 3 groups: intense, faint, and no ISI. RESULTS: Relative to patients
without ISI, those with ISI showed significantly slower gait speed, longer step
time, decreased single-limb support time, increased double-limb support time, and
limited range of motion of knee and ankle (P<.05). Increased intensity tended to
correlate with poor gait function including slower gait speed, longer step time,
decreased single-limb support time, and increased double-limb support time. The
modified JOA and Nurick scale did not correlate with ISI. CONCLUSIONS: In
patients with CSM who received surgical treatment, more intense ISI on
T2-weighted MRI correlated preoperatively with increased difficulties in gait
function. Gait analysis may be a useful tool for evaluating gait functions in
cervical myelopathy.
