abstract = {Neural plasticity is a major factor driving cortical
reorganization after stroke. We here tested whether
repetitively enhancing motor cortex plasticity by means of
intermittent theta-burst stimulation (iTBS) prior to
physiotherapy might promote recovery of function early after
stroke. Functional magnetic resonance imaging (fMRI) was
used to elucidate underlying neural mechanisms. Twenty-six
hospitalized, first-ever stroke patients (time since stroke:
1-16 days) with hand motor deficits were enrolled in a
sham-controlled design and pseudo-randomized into 2 groups.
iTBS was administered prior to physiotherapy on 5
consecutive days either over ipsilesional primary motor
cortex (M1-stimulation group) or parieto-occipital vertex
(control-stimulation group). Hand motor function, cortical
excitability, and resting-state fMRI were assessed 1 day
prior to the first stimulation and 1 day after the last
stimulation. Recovery of grip strength was significantly
stronger in the M1-stimulation compared to the
control-stimulation group. Higher levels of motor network
connectivity were associated with better motor outcome.
Consistently, control-stimulated patients featured a
decrease in intra- and interhemispheric connectivity of the
motor network, which was absent in the M1-stimulation group.
Hence, adding iTBS to prime physiotherapy in recovering
stroke patients seems to interfere with motor network
degradation, possibly reflecting alleviation of post-stroke
diaschisis.},
