ABSTRACT
Emotional abnormality in major depressive disorder (MDD) is generally regarded to be associated with functional dysregulation in the affective network (AN). The present study examined the changes in characteristics of AN connectivity of MDD patients before and after repetitive transcranial magnetic stimulation (rTMS) treatment over the left dorsolateral prefrontal cortex, and to further assess how these connectivity changes are linked to clinical characteristics of patients. Functional connectivity (FC) in the AN defined by placing seeds in the bilateral amygdale was calculated in 20 patients with MDD before and after rTMS, and in 20 healthy controls (CN). Furthermore, a linear regression model was used to obtain correlations between FC changes and Hamilton depression scale (HAMD) changes in MDD before and after rTMS. Before rTMS, compared with CN, MDD exhibited significantly lower FC between left insula (INS.L), right superior and inferior frontal gyrus (SFG.R and IFG.R), right inferior parietal lobule (IPL.R), and amygdala, and showed an increment of FC between the bilateral precuneus and amygdala in AN. After rTMS, MDD exhibited a significant increase in FC in the INS.L, IFG.R, SFG.R, IPL.R, and a significant reduction in FC in the precuneus. Interestingly, change in FC between INS.L and left amygdala was positively correlated with change in HAMD scores before and after rTMS treatment. rTMS can enhance affective network connectivity in MDD patients, which is linked to emotional improvement. This study further suggests that the insula may be a potential target region of clinical efficacy for MDD to design rationale strategies for therapeutic trials.
ABSTRACT
OBJECTIVE: To analyze the effects of biofeedback combined with task-oriented training on hand function, Gesell's infant development scale score (Gesell) and balance ability in children with spastic cerebral palsy (SCP). METHODS: 66 children with SCP admitted to our hospital from January 2016 to June 2018 were randomly divided into the control group and the observation group. The control group ( n=33) received conventional rehabilitation treatment, and the observation group ( n=33) received biofeedback combined with task-oriented training based on the treatment of control group. After 6-month treatment, Modified Ashworth scale (MAS) score, Berg balance scale (BBS) score, standing and walking function score in gross motor function scale (GMFM), assisting hand assessment scales (AHA) score, Gesell scale score and satisfaction of the children's parents were compared between the two groups. RESULTS: The MAS score after treatment was lower than that before treatment in both two groups ( P<0.05), and the BBS score after treatment was higher than that before treatment in both two groups ( P<0.05). After treatment, the MAS score in the observation group was lower than the control group, and the BBS score in the observation group was higher than the control group ( P<0.05). The scores of standing and walking function after treatment were higher than that before treatment in both two groups ( P<0.05). After treatment, the scores of standing and walking function in the observation group were higher than the control group ( P<0.05). The AHA score and Gesell developmental quotient (DQ) score after treatment were higher than that before treatment in both two groups ( P<0.05). After the treatment, the AHA score and Gesell DQ score in the observation group were higher than the control group ( P<0.05). The satisfaction rate of rehabilitation treatment in the observation group was higher than the control group (90.91% vs. 60.61%, P<0.05). CONCLUSION: Biofeedback combined with task-oriented training can improve balance ability, spasm relieve, hand function, development level, standing and walking function in the children with spastic cerebral palsy and increase the treatment satisfaction degree of children's guardians.
