β--oscillations reflect recovery of the paretic upper limb in subacute stroke

So what the hell do stroke survivors do with this information?

What fucking stupidity.  Tell me EXACTLY how this is going to help survivors recover. EXACTLY!

Abstract: 

Study identified neural correlates of post-stroke recovery using longitudinal magnetoencephalography (MEG) assessments in subacute stroke survivors. Twenty-two first-ever, subcortical ischemic stroke survivors with unilateral mild-to-moderate hand paresis were evaluated at 3, 5, and 12 weeks after stroke using a finger-lifting task in the MEG. Cortical activity patterns in the beta (β)-band (16-30 Hz) were compared with matched healthy controls. All stroke survivors had improvements in the Action Research Arm Test (ARAT) and Fugl-Meyer upper extremity (FM-UE) scores between 3 and 12 weeks. At 3 weeks post-stroke the peak amplitudes of the movement-related ipsilesional β-band event-related desynchronization (β-ERD) and synchronization (β-ERS) in primary motor cortex were significantly lower than the healthy controls and were correlated with both the FM-UE and ARAT scores. The decreased β-ERS peak amplitudes were observed both in paretic and non-paretic hand movement particularly at 3 weeks post-stroke, suggesting a generalized disinhibition status. The peak amplitudes of ipsilesional β-ERS at week 3 post-stroke correlated with the FM-UE score at 12 weeks but no longer significant when controlling for the FM-UE score at 3 weeks post-stroke. Although early β-band activity does not independently predict outcome at 3 months after stroke, it mirrors functional changes, giving a potential insight into the mechanisms underpinning recovery of motor function in subacute stroke.
