Oh fuck, more stupid useless prediction crapola. Survivors want EXACT STROKE REHAB PROTOCOLS that deliver results. This is useless for survivors.
Premotor dorsal white matter integrity for the prediction of upper limb motor impairment after stroke
Abstract
Corticospinal
tract integrity after stroke has been widely investigated through the
evaluation of fibres descending from the primary motor cortex. However,
about half of the corticospinal tract is composed by sub-pathways
descending from premotor and parietal areas, to which damage may play a
more specific role in motor impairment and recovery, particularly
post-stroke. Therefore, the main aim of this study was to investigate
lesion load within corticospinal tract sub-pathways as predictors of
upper limb motor impairment after stroke. Motor impairment (Fugl-Meyer
Upper Extremity score) was evaluated in 27 participants at one week and
six months after stroke, together with other clinical and demographic
data. Neuroimaging data were obtained within the first week after
stroke. Univariate regression analysis indicated that among all neural
correlates, lesion load within premotor fibres explained the most
variance in motor impairment at six months (R2 = 0.44, p < 0.001).
Multivariable regression analysis resulted in three independent,
significant variables explaining motor impairment at six months;
Fugl-Meyer Upper Extremity score at one week, premotor dorsal fibre
lesion load at one week, and age below or above 70 years (total R2 = 0.81; p < 0.001).
Early examination of premotor dorsal fibre integrity may be a promising
biomarker of upper limb motor impairment after stroke.
