Action observation for upper limb rehabilitation after stroke.

Background: Action observation (AO) is a physical rehabilitation approach that facilitates the occurrence of neural plasticity through the activation of the mirror-neural system, promoting motor recovery in people with stroke.

Objectives: To assess whether AO enhances upper limb motor function in people with stroke.

Search Methods: We searched the Cochrane Stroke Group Trials Register (last searched 18 May 2021), the Cochrane Central Register of Controlled Trials (18 May 2021), MEDLINE (1946 to 18 May 2021), Embase (1974 to 18 May 2021), and five additional databases.

Electroencephalographic changes using virtual reality program: technical note.

The aim of the study was to describe the technique of an electroencephalographic (EEG) assessment using the Emotiv EPOC® during the performance of a virtual reality motor task and compare theta, alpha, beta and gamma power frequencies between left and right hemispheres. This is technical note in which 9 healthy young subjects were submitted to an evaluation with Emotiv EPOC® during the Nintendo® Wii 'Basic Step' virtual game using the Wii Balance Board (WBB) on a support 13 centimeters high. The Wilcoxon statistical test was applied and pairing between the cerebral hemispheres was performed.

Brain activity during a lower limb functional task in a real and virtual environment: A comparative study.

Background: Virtual Reality (VR) has been contributing to Neurological Rehabilitation because of its interactive and multisensory nature, providing the potential of brain reorganization. Given the use of mobile EEG devices, there is the possibility of investigating how the virtual therapeutic environment can influence brain activity.

Objective: To compare theta, alpha, beta and gamma power in healthy young adults during a lower limb motor task in a virtual and real environment.
