To observe the clinical effects of transcranial direct current stimulation (tDCS) combined with conventional swallowing rehabilitation training on post-stroke dysphagia and explore its long-term efficacy. A total of 40 patients with dysphagia after the first stroke were randomly divided into a treatment group (n = 20) and a conventional group (n = 20). The treatment group received tDCS combined with conventional swallowing rehabilitation training, while the conventional group only received conventional swallowing rehabilitation training. The Standardized Swallowing Assessment (SSA) Scale and the Penetration-Aspiration Scale (PAS) were used to assess dysphagia before and after treatment, at the end of 10 treatments, and at the 3-month follow-up. The changes in infection indicators [the white blood cell (WBC), C-reactive protein (CRP) and procalcitonin (PCT)], the oxygenation indicator [arterial partial pressure of oxygen (PaO₂)] and nutrition-related indicators [hemoglobin (Hb) and serum prealbumin (PAB)] were compared before and after treatment. The SSA and PAS scores were lower in both groups after treatment than before treatment, and the difference was statistically significant (P < 0.01). The SSA and PAS scores of the treatment group were lower than those of the conventional group before and after treatment and during follow-up, and the difference was statistically significant (P < 0.05, P < 0.01). A within-group comparison showed that WBC, CRP and PCT after treatment were lower than those before treatment, and the difference was statistically significant (P < 0.05). The PaO₂, Hb and serum PAB were higher after treatment than before treatment, with a statistically significant difference (P < 0.05). The WBC, CRP and PCT of the tDCS group were lower than those of the conventional group, and PaO₂, Hb and serum PAB were higher in the treatment group than in the conventional group, with a statistically significant difference (P < 0.01). The tDCS combined with conventional swallowing rehabilitation training can improve dysphagia with a better effect than conventional swallowing rehabilitation training and has a certain long-term efficacy. In addition, tDCS combined with conventional swallowing rehabilitation training can improve nutrition and oxygenation and reduce infection levels.

Crossed cerebellar diaschisis (CCD) has been widely investigated in patients with supratentorial stroke. However, the role of CCD in lower limb recovery after stroke is still unknown. In this study, using a region-of-interest-based analysis of diffusion tensor imaging (DTI), a total of 44 cases of stroke within 3 months onset were enrolled for assessment of the cerebral peduncle (CP) and middle cerebellar peduncles (MCP) in CCD. Compared with the control group, the fractional anisotropy ratio (rFA) and laterality index (LI) of the CP and MCP in the stroke group significantly decreased. The rFA of the MCP (unaffected side/affected side) showed a more significant correlation with 1-year paresis grading (PG), lower extremity PG, upper extremity PG, National Institutes of Health Stroke Scale (NIHSS), and functional independence measure (FIM) motor item score, in comparison to the rFA of the CP (affected side/unaffected side) (r = −0.698 vs. r = −0.541, r = −0.651 vs. r = −0.386, r = −0.642 vs. r = −0.565, r = −0.519 vs. r = −0.403, and r = 0.487 vs. r = 0.435, respectively). Furthermore, the LI of the CP had a more significant association with 1-year Brunel Balance Assessment (BBA), upper extremity PG, and Modified Rankin Scale (mRS) as compared to the LI of the MCP (r = 0.573 vs. r = 0.452; r = −0.554 vs. r = −0.528; and r = −0.494 vs. r = −0.344, respectively). We set the cutoff point for the MCP rFA at 0.925 (sensitivity: 79% and specificity: 100%) for predicting lower extremity motor function prognosis and found the receiver operating characteristic (ROC) curve of MCP rFA was larger than that of CP rFA (0.893 vs. 0.737). These results reveal that the MCP may play a significant role in the recovery of walking ability after stroke.

Background: Hemiplegic shoulder pain (HSP) is a major cause of disability that is still challenging to manage in clinical practices. Both pulsed radiofrequency (PRF) and repetitive transcranial magnetic stimulation (rTMS) could reduce poststroke HSP to certain extents. However, it remains unknown whether combined PRF and rTMS treatment could increase analgesic efficacy for poststroke HSP. Objectives: To evaluate the therapeutic efficacy of combined PRF and transcranial magnetic stimulation in treating HSP. Study Design: This was a randomized, assessor‐blinded pilot study. Setting: The rehabilitation department of a single hospital. Methods: In this pilot study, a 3‐arm study design was utilized to compare the treatment efficacy of combined PRF and rTMS treatment with a single PRF or rTMS strategy. Patients were randomly assigned to receive PRF, rTMS, or combined treatment. Outcomes assessments included pain intensity, motor activity, and neurophysiological activities. Results: Our data indicated that rTMS acted more efficiently to reduce pain than PRF treatment. Combined treatment had a larger long‐term efficacy than rTMS treatment alone. Both combined and single treatment improved motor recovery and neural transmissions, such as suprascapular nerve amplitude and somatosensory N20. Limitations: As we designed a pilot study, the sample size was small in each treatment arm. Our findings thus need to be validated in future large studies. Conclusion(s): These novel findings provide a safe and effective treatment strategy for poststroke HSP by combining PRF with rTMS treatment.
