Rehabilitation von Parkinson-Patienten mit Tiefenhirnstimulation: Erfahrungen des Neurologischen Rehabilitationszentrums Godeshöhe
Rationale and Design of a Multicentre, Double-Blind, Prospective, Randomized, European and Canadian Study: Evaluating Patient Outcomes and Costs of Managing Adults with Post-Stroke Focal Spasticity
Erscheinung:
/ Journal of Rehabilitation Medicine
Objective:
This report describes the design of a study aiming to provide evidence for the extended use of botulinum toxin A in focal post-stroke upper and lower limb spasticity and to evaluate the impact of incorporating botulinum toxin treatment into the rehabilitation of patients with spasticity. Design: International, prospective, randomized, double-blind, placebo-controlled study with an open-label extension.
Methods:
Approximately 300 adults with a stroke occurring ≥ 3 months before screening, presenting with symptoms and signs of an upper motor neuron syndrome and focal spasticity-related functional impairment, were randomized to botulinum toxin (BOTOX®, Allergan Inc.) + standard care or placebo + standard care. Study medication was administered at baseline and again at Week 12 if required, with follow-up to 52 weeks. The primary endpoint was the number of patients who achieved their investigator-rated principal active functional goal (as measured by Goal Attainment Scaling), at 10 weeks after the second injection (Weeks 22−34) or at the 24-week visit if no second injection was administered. Secondary endpoints included changes from baseline in level of goal achievement, health-related quality of life and resource utilization.
Conclusion:
Botulinum toxin A Economic Spasticity Trial (BEST) will provide information regarding clinical and cost-effectiveness of botulinum toxin + standard care vs standard care alone in patients with upper and/or lower limb post-stroke spasticity typically seen in clinical practice.
Trial registration: ClinicalTrials.gov number NCT00549783.
Representation of Virtual Arm Movements in Precuneus

/ Experimental Brain Research
Arm movements can easily be adapted to different biomechanical constraints. However, the cortical representation of the processing of visual input and its transformation into motor commands remains poorly understood. In a visuo-motor dissociation paradigm, subjects were presented with a 3-D computer-graphical representation of a human arm, presenting movements of the subjects’ right arm either as right or left arm. In order to isolate possible effects of coordinate transformations, coordinate mirroring at the body midline was implemented independently. In each of the resulting four conditions, 10 normal, right-handed subjects performed three runs of circular movements, while being scanned with O15-Butanol-PET. Kinematic analysis included orientation and accuracy of a fitted ellipsoid trajectory. Imaging analysis was performed with SPM 99 with activations threshold at P < 0.0001 (not corrected). The shape of the trajectory was dependent on the laterality of the arm, irrespective of movement mirroring, and accompanied by a robust activation difference in the contralateral precuneus. Movement mirroring decreased movement accuracy, which was related to increased activation in the left insula. Those two movement conditions that cannot be observed in reality were related to an activation focus at the left middle temporal gyrus, but showed no influence on movement kinematics. These findings demonstrate the prominent role of the precuneus for mediating visuo-motor transformations and have implications for the use of mirror therapy and virtual reality techniques, especially avatars, such as Nintendo Wii in neurorehabilitation.
