Objective: The purpose of this study was to visualize
the corticoreticular pathway (CRP) of stroke hemiplegic
patients by using probabilistic tractography and to clarify
the relationship between the degree of CRP damage and
the trunk function.
Methods: The CRP of 17 convalescent patients with
stroke hemiplegia was visualized using probabilistic
tractography, and the results of the Trunk Control Test
(TCT) and Functional Assessment for Control of the
Trunk (FACT) of the non-injured and injured groups
were compared.
Results: There were no significant differences in all
TCT and FACT scores between the CRP non-injured
and injured groups.
Conclusion: If the corticospinal tract in the cerebral
hemisphere is not injured, TCT and FACT might not
reflect the qualitative aspects of trunk function
associated with CRP injury, such as reduced motor
efficiency and antigravity extension activity.
