Cerebral ischemic injury is the main manifestation of stroke, and its incidence in stroke patients is 70-80%. Although ischemic stroke can be treated with tissue-type plasminogen activator, its time window of effectiveness is narrow. Therefore, the incidence of paralysis, hypoesthesia, aphasia, dysphagia, and cognitive impairment caused by cerebral ischemia is high. Nerve tissue regeneration can promote the recovery of the aforementioned dysfunction. Neural stem cells can participate in the reconstruction of the damaged nervous system and promote the recovery of nervous function during self-repair of damaged brain tissue. Neural stem cell transplantation for ischemic stroke has been a hot topic for more than 10 years. This review discusses the treatment of ischemic stroke with neural stem cells, as well as the mechanisms of their involvement in stroke treatment.

[Purpose] This study aimed to explore whether trunk kinesiology taping (KT) can improve trunk function, mobility, and balance in post-stroke patients with hemiparesis. [Participants and Methods] We conducted a single-group pre-post design pilot feasibility study. Thirteen individuals with post-stroke hemiplegia were recruited for this study. All patients received therapeutic trunk KT on the skin, representing the direction of fibres of the trunk muscles underneath. We used the Trunk Impairment Scale (TIS) and Trunk Control Test (TCT) to measure trunk function, Fugl-Meyer assessment (FMA) for balance, limits of stability (LOS) to evaluate balance, and the modified Rivermead mobility index (MRMI) to assess mobility in post-stroke patients. All measures were assessed before and immediately after the intervention. [Results] No adverse effects were found and all patients completed the trial. Compared to the baseline, TIS scores were significantly increased after KT, whereas no changes in TCT score were detected. The directional control of LOS was significantly improved, while no significant changes were seen in the other parameters of LOS, FMA-balance, and MRMI scores. [Conclusion] The results of this investigation show that trunk KT has immediate effects that improve certain trunk functional and balance parameters in stroke patients.

Intermittent theta-burst stimulation (iTBS) has been suggested to improve poststroke rehabilitation. The cerebellum is considered crucial for motor control. However, the effects of cerebellar iTBS with routine physical therapy on balance and motor recovery in subacute and chronic stroke patients have not been explored.

To investigate the effect of trunk control training on trunk function, balance, mobility and functional independence in hemiplegia patients after acute stroke, and to compare the therapeutic effects with conventional stroke rehabilitation.

Extremely low frequency electromagnetic fields (ELF-EMF) can improve the learning and memory impairment of rats with Alzheimer's disease, however, its effect on cerebral ischemia remains poorly understood. In this study, we established rat models of middle cerebral artery occlusion/reperfusion. One day after modeling, a group of rats were treated with ELF-EMF (50 Hz, 1 mT) for 2 hours daily on 28 successive days. Our results showed that rats treated with ELF-EMF required shorter swimming distances and latencies in the Morris water maze test than those of untreated rats. The number of times the platform was crossed and the time spent in the target quadrant were greater than those of untreated rats. The number of BrdU/NeuN cells, representing newly born neurons, in the hippocampal subgranular zone increased more in the treated than in untreated rats. Up-regulation in the expressions of Notch1, Hes1, and Hes5 proteins, which are the key factors of the Notch signaling pathway, was greatest in the treated rats. These findings suggest that ELF-EMF can enhance hippocampal neurogenesis of rats with cerebral ischemia, possibly by affecting the Notch signaling pathway. The study was approved by the Institutional Ethics Committee of Sichuan University, China (approval No. 2019255A) on March 5, 2019.
