Change of cognitive functions after stroke with rehabilitation systems

Abstract

Abstract The objective of this study is to assess and compare the effect of applying a computerised cognitive training programme and virtual environment rehabilitation system on cognitive functions in patients after a stroke. Methods. A controlled trial included 121 persons referred to second stage rehabilitation. The subjects were differentiated into three impact groups by a single blinded trial. Results. The trial revealed that cognitive functions improved in all patient groups (p<0.001). A paired comparison analysis of all groups demonstrated a tendency for cognitive functions, evaluated by the MoCA–LT test, to be more strongly improved in patients who practised a computerised cognitive training programme during their OT sessions than those who did not (p=0.054). Conclusions. The final outcome of the trial was that cognitive functions significantly improved in patients who practised computerised cognitive training programmes or virtual environment rehabilitation systems, compared to those participants who only had occupational therapy sessions.
