Objective:To observe the clinical efficacy of continuous theta burst stimulation in the treatment of post-stroke aphasia (PSA).Methods:Forty-six patients with post-stroke aphasia were randomly divided into an observation group and a control group, with 23 cases in each group. In addition to conventional rehabilitation and speech-language therapy, the observation group received daily theta burst stimulation (cTBS) targeting the contralesional inferior frontal gyrus, the superior temporal gyrus, and the superior frontal gyrus. The control group received sham stimulation over the same areas. The treatment was 5 days per week for 3 weeks. Before and after the treatment, both groups were evaluated using the China Rehabilitation Research Center′s aphasia examination method (CRRCAE), the Boston diagnostic aphasia examination (BDAE), the brief mental scale (MMSE), and the Stroke Aphasia Quality of Life scale (SAQOL-39).Results:After the treatment, intra-group comparison showed significantly greater improvements among the observation group in terms of their average CRRCAE listening comprehension (112.74±8.935), repetition (115.74±16.015), speaking (99.91±6.273), oral reading (98.22±14.087), and reading (86.57±8.101) sub-scores and their average BDAE [3.00 (3.00, 4.00)], MMSE [21.00 (20.00, 24.00)] and SAQOL-39 (112.96±21.995) scores.Conclusions:Continuous theta burst transcranial magnetic stimulation can effectively improve the speech, cognition and life quality of persons with post-stroke aphasia. This therapy is worthy of clinical application and promotion.

To better analyze the problem of abnormal neuromuscular coupling related to motor dysfunction for stroke patients, the functional coupling of the multichannel electromyography (EMG) were studied and the difference between stroke patients and healthy subjects were further analyzed to explore the pathological mechanism of motor dysfunction after stroke. Firstly, the cross-frequency coherence (CFC) analysis and non-negative matrix factorization (NMF) were combined to construct a CFC-NMF model to study the linear coupling relationship in bands and the nonlinear coupling characteristics in different frequency ratios during elbow flexion and extension movement. Furthermore, the significant coherent area and sum of cross-frequency coherence were respectively calculated to quantitatively describe the intermuscular linear and nonlinear coupling characteristics. The results showed that the linear coupling relationship between multichannel muscles was different in frequency bands and the overall coupling was stronger in low frequency band. The linear coupling strength of the stroke patients was lower than that of the healthy subjects in different frequency bands especially in beta and gamma bands. For the nonlinear coupling, the intermuscular coupling strength of stroke patients in different frequency ratios was significantly lower than that of the healthy subjects, and the coupling strength in the frequency ratio 1∶2 was higher than that in the frequency ratio 1∶3. This method can provide a theoretical basis for exploring the intermuscular coupling mechanism of patients with motor dysfunction.
