Abstract
Background: Repetitive transcranial magnetic stimulation (rTMS) targeting the primary somatosensory cortex (S1) has a potential effect on somatosensory functioning following a stroke. However, S1-rTMS was combined with peripheral therapies in previous trials. Moreover, these studies have commonly targeted the ipsilesional S1 with excitatory rTMS paradigms.
Methods: This double-blind, randomized trial (registration number: ChiCTR2200059098) investigated two forms of paradigms, that is ipsilesional excitatory and contralesional inhibitory rTMS, as a stand-alone treatment in post-stroke somatosensation. Patients in the acute and subacute phases of stroke were randomly assigned to either contralesional 1-Hz or ipsilesional 10-Hz rTMS group and received 10 daily sessions of treatment in two consecutive weeks.
Results: Results indicate that the contralesional inhibitory and ipsilesional excitatory stimulation were equally effective in improving somatosensory functioning. Moreover, this effect was most prominent in deep sensations and subjective sensations. Using single-pulse EMG recordings, our data also revealed an increased MEP amplitude in the ipsilesional motor cortex following ipsilesional excitatory treatment.
Conclusion: This preliminary study demonstrates the primary somatosensory cortex as an effective rTMS target in somatosensory recovery following stroke.
期刊介绍：
Frontiers in Human Neuroscience is a first-tier electronic journal devoted to understanding the brain mechanisms supporting cognitive and social behavior in humans, and how these mechanisms might be altered in disease states. The last 25 years have seen an explosive growth in both the methods and the theoretical constructs available to study the human brain. Advances in electrophysiological, neuroimaging, neuropsychological, psychophysical, neuropharmacological and computational approaches have provided key insights into the mechanisms of a broad range of human behaviors in both health and disease. Work in human neuroscience ranges from the cognitive domain, including areas such as memory, attention, language and perception to the social domain, with this last subject addressing topics, such as interpersonal interactions, social discourse and emotional regulation. How these processes unfold during development, mature in adulthood and often decline in aging, and how they are altered in a host of developmental, neurological and psychiatric disorders, has become increasingly amenable to human neuroscience research approaches. Work in human neuroscience has influenced many areas of inquiry ranging from social and cognitive psychology to economics, law and public policy. Accordingly, our journal will provide a forum for human research spanning all areas of human cognitive, social, developmental and translational neuroscience using any research approach.
