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.

Key words: probabilistic tractography, corticoreticular pathway, trunk function, stroke hemiplegic patients, convalescent
