BoNT-A related changes of cortical activity in patients suffering from severe hand

Popis výsledku v původním jazyce

Investigations were performed to localize and analyze the botulinum toxin (BoNT-A) related changes of cerebral cortex activation in chronic stroke patients suffering from severe hand paralysis with arm spasticity. Effects on task- related cerebral activation were evaluated by functional magnetic resonance imaging (fMRI). Methods: 14 patients (5 males, 9 females,mean age 55.3 years) suffering from upper limb post-stroke spasticity were investigated. The change of armspasticitywas assessed by using the modified Ashworth scale (MAS). FMRI sessionswere performed before (W0), four weeks (W4) and 11 weeks (W11) after BoNT-A application. Patients were scannedwhile performing imaginarymovementwith the impaired hand. Group fMRI analysis included patient age asa covariate. Results: BoNT-A treatmentwas effective in alleviation of armspasticity. Mean MASwas at Week 0: 2.5 (SD 0.53), at Week 4: 1.45 (SD 0.38), at Week 11: 2.32 (SD 0.44). Task-related fMRI prior to the treatment showed extensive ac
