Neurophysiological prognostic factors of motor function and spasticity after stroke

Purpose: Understanding the neural mechanisms of recovery motor control and development spasticity after stroke is paramount importance for neurorehabilitation.Methods: For this purpose, we have analyzed several TMS EEG variables their association with spasticity. Forty-two subjects taken part in investigation. The neurophysiological examination included assessments by transcranial magnetic stimulation (TMS), intra- inter-hemispheric coherence different frequency bands (e.g. Theta (4.0–7.99 Hz)) as determined quantitative electroencephalography (qEEG). Motor function has been measured Fugl-Meyer (FM), modified Ashworth scale. Multiple univariate multivariate linear regression analyses performed to identify predictors spasticity.Results: Univariate shown a significant interaction amplitude threshold (MT) injured MT, central conduction time uninjured hemisphere according Fugle-Meyer (FM). Also between MT spasticity.Multivariate beta injured, interhemispheric prediction FM. hemisphere, delta theta C3-C4 shown.These suggests that higher activity lesioned strengthens FM scores. Higher scores.Conclusions: Our results suggest both hemispheres strongest stroke. Moreover, cortical qEEG provides additional information, specifying low-frequency are stroke.Thus, combination predicting opportunities study nonlinear relationships influencing networks, release subcortical
