Abstract EN
The red nucleus (RN) is involved in motor control and it is known to have potential to compensate for injury of the corticospinal tract (CST).
We investigated the change of connectivity of the RN (RNc) and its relation to motor function in patients with striatocapsular hemorrhage.
Thirty-five chronic patients with striatocapsular hemorrhage were recruited.
Motricity Index (MI), Modified Brunnstrom Classification (MBC), and Functional Ambulation Category (FAC) were measured for motor function.
The probabilistic tractography method was used for evaluation of the RNc.
Fractional anisotropy (FA), mean diffusivity (MD), and tract volume (TV) of the RNc were measured.
FA and TV ratios of the RNc in patients with discontinuation of the affected CST were significantly higher than those of patients with preserved integrity of the CST in the affected hemisphere (p<0.05).
TV ratio of the RNc showed significant negative correlation with upper MI (weak correlation, r=-0.35), total MI (weak correlation, r=-0.34), and MBC (moderate correlation, r=-0.43), respectively (p<0.05).
We found that the neural structure of the RNc was relatively increased in the unaffected hemisphere compared with the affected hemisphere in patients with more severe injury of the CST.
