Peripheral Axonal Excitability In Hemiplegia Related To Subacute Stroke, Zeynep Turan, Murat Zi̇nnuroğlu
Turkish Journal of Medical Sciences
Background/aim: This study aims to investigate peripheral nerve excitability in patients with subacute stroke. Materials and methods: The study was performed in 29 stroke patients within the subacute period and 29 healthy controls using QTRAC software and TRONDNF protocol. The threshold electrotonus, recovery cycle, stimulus-response, strength-duration, and current-threshold relationships were recorded. Results: The membrane was more hyperpolarized, and excitability was decreased in the hemiplegic side. The impairment of inward rectifying channel function, degree of hyperpolarization, and decrease of excitability were directly related to the Brunnstrom stages, which were more pronounced in lower stages. Conclusion: The lower motor neurons were affected …

Background/aim: Silent cerebral infarct (SCI) is an ischemic lesion seen before clinical signs of brain infarct and ischemic changes in brain tissue. This study aimed to detect SCI with noninvasive methods and to determine related risk factors in patients with sickle cell anemia (SCA). Materials and methods: Fifty-four SCA patients who had no history of cerebral infarct and whose neurological examinations were normal were included in this study. Brain magnetic resonance imaging (MRI) and diffusion MRI were taken and the acquired data was compared statistically. Results: SCI was detected in 11.1% (6/54) of the patients. No statistical differences in age, …
