Brain-computer interface (BCI) systems have been suggested as a promising tool for neurorehabilitation. However,
to date, there is a lack of
homogeneous findings. Furthermore, no systematic reviews have analyzed the degree
of validation of these interventions for upper limb (UL) motor rehabilitation poststroke. OBJECTIVES: The study aims were to compile all available studies that
assess an UL intervention based on an electroencephalography (EEG) BCI system in
stroke; to analyze the methodological quality of the studies retrieved; and to
determine the effects of these interventions on the improvement of motor
abilities. TYPE: This was a systematic review. LITERATURE SURVEY: Searches were
conducted in PubMed, PEDro, Embase, Cumulative Index to Nursing and Allied
Health, Web of Science, and Cochrane Central Register of Controlled Trial from
inception to September 30, 2015. METHODOLOGY: This systematic review compiles all
available studies that assess UL intervention based on an EEG-BCI system in
patients with stroke, analyzing their methodological quality using the Critical
Review Form for Quantitative Studies, and determining the grade of recommendation
of these interventions for improving motor abilities as established by the Oxford
Centre for Evidence-based Medicine. The articles were selected according to the
following criteria: studies evaluating an EEG-based BCI intervention; studies
including patients with a stroke and hemiplegia, regardless of lesion origin or
temporal evolution; interventions using an EEG-based BCI to restore functional
abilities of the affected UL, regardless of the interface used or its combination
with other therapies; and studies using validated tools to evaluate motor
function. SYNTHESIS: After the literature search, 13 articles were included in
this review: 4 studies were randomized controlled trials; 1 study was a
controlled study; 4 studies were case series studies; and 4 studies were case
reports. The methodological quality of the included papers ranged from 6 to 15,
and the level of evidence varied from 1b to 5. The articles included in this
review involved a total of 141 stroke patients.
CONCLUSIONS: This systematic
review suggests that BCI interventions may be a promising rehabilitation approach
in subjects with stroke.
LEVEL OF EVIDENCE: II.
