Abstract
STUDY DESIGN: Retrospective study.
OBJECTIVES:
Few studies have reported a relationship between central
motor conduction time (CMCT), which evaluates corticospinal function, and
degree of spinal cord compression in patients with myelopathy. Thus, there
is no consensus on predicting the degree of prolonged CMCT on the basis of
the degree of spinal cord compression. If a correlation exists between CMCT and spinal cord compression, then spinal cord compression may be a useful noninvasive clinical indicator of corticospinal function. Therefore, this study evaluated the relationship between CMCT and cervicalspinal cord compression measured by magnetic resonance imaging (MRI) in patients with cervical spondylotic myelopathy (CSM).

RESULTS:
Correlations between CMCT and flattening as well as
anteroposterior diameter of the spinal cord at the lesion level were
observed. Strong correlations between CMCT and the ratio of the flattening
and anteroposterior diameter parameters at the lesion level to that at the
C2/3 level were also observed.
CONCLUSIONS:
Measurement of spinal cord compression may be useful for the
evaluation of corticospinal function as a proxy for CMCT in patients
with
CSM.
