So you described something but DID NOTHING to get survivors recovered. And cherry picked better patients besides. Hope you're OK with not recovering when you are the 1 in 4 per WHO that has a stroke unless you take action now to get stroke recovery solved. 17 years later and I bet your hospital incompetently did no followup with this to get patients recovered!
Evolution of Brain Activation with Good and Poor Motor Recovery after Stroke
2006, Neurorehabilitation and Neural Repair
Abstract
Objective.
To characterize the evolution of brain activation in stroke patients
with variable motor recovery and quantify changes relative to healthy
controls.
Methods.
Serial PET activation studies, using a simple
finger-tapping task, and quantitative measures of motor performance were
obtained in 9 patients (2-7 weeks poststroke and 6 months later) and
compared with serial healthy volunteer data. Results. Patients with
moderate impairment and good recovery (n = 5) activated the
primary sensorimotor cortex (SM1) contralateral to the paretic hand
moved, bilateral supplementary motor area (SMA), contralateral cingulate
gyrus, and ipsilateral lateral premotor cortex. Activation in the
bilateral SMA was greater at the initial study but reduced over time
compared to healthy controls and poor recoverers. Patients with severe
impairment and poor recovery (n =4) showed limited activation of
contralateral SM1 and SMA at both studies and no significant change over
time. A posterior shift in SM1 activation was evident in good and poor
recoverers.
Conclusions.
Activation of typical motor regions and
recruitment of additional sites occur subacutely poststroke, with
evolution to normal patterns in moderately impaired patients who recover
well. In comparison, severely impaired, poor-recovery patients show
persistent, reduced activation. Dynamic changes in SMA, differentially
observed in good recoverers over 6 months, highlight its importance in
recovery.
