A systematic review exploring the relationship of cortical activity and recovery of upper limb sensorimotor impairments after stroke (original) (raw)

2017

Abstract

Purpose: At six months post-stroke, 33-66% of survivors do not present with full recovery of upper limb function. One of the methods of measuring cortical neurophysiological mechanisms of brain recovery in stroke, is electroencephalography (EEG). Disruption of neural connectivity can be measured by event related potentials such as somatosensory evoked potentials (SSEPs) and event related synchronisation. The aim of this systematic review was to examine the current evidence about the changes of cortical activity measured by EEG or magnetoencephalography (MEG) in association with sensorimotor upper limb impairments in stroke. Method: In order to identify the relevant studies, electronic searches, abstract and full-text papers were independently reviewed by two reviewers. From 1614 papers, 32 papers were selected for risk of bias assessment. Nine papers were then included in the review; 7 used EEG and 2 used MEG methodology. Results: In total, 321 people with stroke were included. Prel...
