RESUMO
OBJECTIVE: This study aimed to investigate whether Functional Electrical Stimulation (FES) and Transcranial Direct Current Stimulation (tDCS) enhanced the effect of Occupational Therapy (OT) on post-stroke limb functional recovery and quality of life, using direct and network meta-analysis. METHODS: A computerized search was conducted in databases such as Medline, Web of Science, Embase, CNKI (China National Knowledge Infrastructure), Wanfang Data, and VIP Information for prospective randomized controlled trials on OT, FES, and tDCS for improving post-stroke limb motor function and quality of life, with the search cutoff date of July 1, 2023. RESULTS: Following the screening process, a total of 8 research articles were incorporated, encompassing 358 participants. Among these, 177 individuals underwent OT exclusively, while 181 individuals underwent a combined regimen of OT alongside electromagnetic therapy. In terms of the intervention methods, the control group received OT treatment only, while the experimental group employed tDCS in 5 studies and FES in 3 studies. Within these investigations, Fugl-Meyer Assessment (FMA) scores were reported in 8 studies. The aggregated mean difference (MD) for FMA scores was 5.08 (95% CI: 2.46, 7.71), with a specific MD of 2.77 (95% CI: 1.46, 4.09) for the tDCS subgroup and 9.04 (95% CI: 5.34, 12.73) for the FES subgroup. Notably, FES combined with OT exhibited significant advantages in enhancing FMA scores when compared to the combination of tDCS and OT. Furthermore, four studies provided data on modified Barthel Index (MBI) scores, yielding a collective MD of 7.20 (95% CI: 4.44, 9.95). CONCLUSION: In patients with stroke, both FES combined with OT and tDCS combined with OT exhibit substantial enhancements in limb function and quality of life compared to OT alone. Notably, FES combined with OT yields superior clinical benefits when compared to the amalgamation of tDCS and OT.
RESUMO
Introduction: Hospital is a stressful place of employment, and a high proportion of healthcare workers, especially the ICU (Intensive Care Unit) nurses were found to be at risk of PTSD. Previous studies showed that taxing working memory through visuospatial tasks during the reconsolidation process of aversive memories can reduce the number of intrusions afterwards. However, the finds could not be replicated by some researches, indicating there may be some boundary conditions that are subtle and complex. Methods: We performed a randomized controlled trial (ChiCTR2200055921; URL: www.chictr.org.cn). In our study, a series of ICU nurses or probationers who performed a cardiopulmonary resuscitation (CPR) were enrolled and instructed to play a visuospatial music tapping game ("Ceaseless Music Note", CMN; Beijing Muyuan Technology Co., Ltd., Beijing, China) at the fourth day after CPR. The numbers of intrusions each day were recorded from the first to the seventh days (24 h×6 day), and the vividness and emotionality of CPR memories were rated at the 4th and 7th days. These parameters were compared between different groups (game with background sound; game with sound off; sound only; none). Results: The game-matching background music can have an add-on effect for single tapping game with no sound in reducing the emotionality of previous aversive memories. Discussion: We proposed that flow experience (the subjective experience of effortless attention, reduced self-awareness, and enjoyment, and may be induced by optimal skill-demands compatibility in challenging tasks) as a key boundary condition for successful reconsolidation intervention.

RESUMO
BACKGROUND: Stroke is a devastating disease and can be sufficiently traumatic to induce post-traumatic stress disorder (PTSD). Post-stroke PTSD is attracting increasing attention, but there was no study assessing the psychometric properties of the PCL-5 in stroke populations. Our study was conducted to examine the psychometric properties of the PTSD Checklist for DSM-5 (PCL-5) in Chinese stroke patients. METHODS: This was a cross-sectional observational study conducted at our hospital. Three hundred and forty-eight Chinese stroke patients came to our hospital for outpatient service were recruited. They were instructed to complete the PCL-5 scales and were interviewed for PTSD diagnosis with the Clinician Administered PTSD Scale for DSM-5 (CAPS-5). The cutoff scores, reliability and validity of the PCL-5 were analyzed. RESULTS: PCL-5 scores in our sample were positively skewed, suggesting low levels of PTSD symptoms. The reliability of PCL-5 was good. Exploratory and confirmatory factor analyses indicated acceptable construct validity, and confirmed the multi-dimensionality of the PCL-5. By CFA analysis, the seven-factor hybrid model demonstrated the best model fit. The PCL-5 also showed good convergent validity and discriminant validity. Receiver operating characteristic (ROC) analyses revealed a PCL-5 score of 37 achieved optimal sensitivity and specificity for detecting PTSD. CONCLUSIONS: Our findings supported the use of PCL-5 as a psychometrically adequate measure of post-stroke PTSD in the Chinese patients.
