The efficacy and safety of incobotulinumtoxinA ≤400 U was demonstrated in subjects with post-stroke upper-limb spasticity in a randomized, double-blind Phase 3 study with an open-label extension (OLEX; EudraCT number 2005-003951-11, NCT00432666). We report a analysis of the duration of the treatment effect. Subjects completing the placebo-controlled main period (single injection cycle with 12-20-week observation) entered the OLEX and received a maximum of five further treatments (maximum duration 69 weeks) with incobotulinumtoxinA ≤400 U at flexible intervals with a minimum duration of 12 weeks, based on clinical need.
View Article and Find Full Text PDFObjective: This post hoc analysis assessed the impact of repeated incobotulinumtoxinA injections on muscle tone, disability, and caregiver burden in adults with upper-limb post-stroke spasticity.
Design: Data from the double-blind, placebo-controlled main period and three open-label extension cycles of two Phase 3, randomized, multicentre trials were pooled.
Methods: Subjects received incobotulinumtoxinA 400 Units at 12-week intervals (±3 days) (study 3001, NCT01392300) or ≤ 400 Units at ≥12-week intervals based on clinical need (study 0410, NCT00432666).
Background: Poststroke spasticity affects motor function and the ability to perform activities of daily living, with the potential to affect quality of life (QoL) and increase caregiver burden.
Objective: To investigate the effect of repeated incobotulinumtoxinA treatment on spasticity-associated functional disability, caregiver burden, and QoL in the 36-week open-label extension of the phase 3 PURE study (NCT01392300).
Design: Open-label extension period of a prospective, double-blind, placebo-controlled, randomized, multicenter study.
Deriving cell populations from human embryonic stem cells (hESCs) for cell-based therapy is considered a promising strategy to achieve functional cells, yet its translation to clinical practice depends on achieving fully defined differentiated cells. In this work, we generated a miRNA-responsive lethal mRNA construct that selectively induces rapid apoptosis in hESCs by expressing a mutant (S184del) Bax variant. Insertion of miR-499 target sites in the construct enabled to enrich hESC-derived cardiomyocytes (CMs) in culture.

Methods: Adults 18-80 years of age with post-stroke upper-limb spasticity who completed the 12-week randomized, double-blind, placebo-controlled main period (MP) of a phase 3 trial (NCT01392300) were eligible to enrol in the 36-week open-label extension period (OLEX). The OLEX included three treatment cycles at fixed 12-week injection intervals; subjects were injected with 400 U incobotulinumtoxinA into the affected upper limb.

Objective: The aim of the study was to report physician experience-based "real-world" treatment patterns with botulinum toxin type A in patients with stroke and traumatic brain injury.
Design: A prospective, multicenter, international observational registry design was used.
Results: Six hundred twenty-seven participants with stroke and 132 participants with traumatic brain injury were assessed and treated by 17 more experienced physicians and 12 less experienced physicians.
Therapeutic implementation of RNA interference (RNAi) through delivery of short interfering RNA (siRNA) is still facing several critical hurdles, which mostly can be solved through the use of an efficient delivery system. We hereby introduce anionic siRNA nanoparticles (NPs) co-assembled by the electrostatic interactions of the semi-synthetic polysaccharide hyaluronan-sulfate (HAS), with siRNA, mediated by calcium ion bridges. The NPs have an average size of 130nm and a mild (-10mV) negative surface charge.

Purpose/objective: To assess the efficacy of modafinil for the treatment of new learning and memory deficits and fatigue in multiple sclerosis. Only 1 previous study in the literature, to our knowledge, examined the effect of modafinil on cognition specifically in persons with multiple sclerosis.
Research Method/design: Sixteen patients with a diagnosis of multiple sclerosis (MS) and documented new learning impairment completed the study.
Introduction: Efficacy and safety of incobotulinumtoxinA in post-stroke upper-limb spasticity were studied.
Methods: Subjects randomized 2:1 to incobotulinumtoxinA (fixed dose 400 U) or placebo, with fixed doses for the primary target clinical pattern (PTCP; flexed elbow, 200 U; flexed wrist, 150 U; clenched fist, 100 U). Doses for non-primary patterns were flexible within predefined ranges.
Botulinum neurotoxin (BoNT) can be injected to achieve therapeutic benefit across a large range of clinical conditions. To assess the efficacy and safety of BoNT injections for the treatment of certain urologic conditions, including detrusor sphincter dyssynergia (DSD), lower urinary tract symptoms due to benign prostatic hyperplasia (BPH), and detrusor overactivity (both neurogenic [NDO] and idiopathic [IDO]), an expert panel reviewed evidence from the published literature. Data sources included English-language studies identified via MEDLINE, EMBASE, CINAHL, Current Contents, and the Cochrane Central Register of Controlled Trials.

This investigation utilized a single case design to evaluate the effects of a dynamic AFO on ambulation in post stroke hemiplegia. A single patient with stroke related hemiplegia using a dynamic AFO underwent gait analysis while walking on level ground. Outcome measures included temporal-spatial gait parameters and bilateral kinematic joint angles at the ankle, knee, and hip with and without AFO.

Traumatic brain injury (TBI) has a poorly understood pathology. Patients suffer from a variety of physical and cognitive effects that worsen as the type of trauma worsens. Some noninvasive insights into the pathophysiology of TBI are possible using magnetic resonance imaging (MRI), computed tomography (CT), and many other forms of imaging as well.

Maximum ulnar compound muscle action potential (CMAP) data were collected at two visits over a 4-6-week period in children with SMA types II and III, 2-17 years of age, at four academic centers. Primary functional outcome measures included the Modified Hammersmith Functional Motor Scale (MHFMS) and MHFMS-Extend.

This article will discuss many of the key concepts regarding chemodenervation and neurolysis in the management of spasticity. Topics that will be discussed include techniques for localization, strengths and limitations of various agents (botulinum toxin, phenol, and alcohol), the value of combination therapies, and the role of nerve blocks (diagnostic and therapeutic). With advancing technology have come newer methods to improve accuracy of localization for the performance of chemodenervation and neurolysis such as electromyographic guidance, electrical stimulation, and ultrasound guidance.

A 53-yr-old woman developed contralateral weakness and fatigue, without autonomic symptoms, 2 wks after receiving an injection with 800 units of botulinum toxin A for management of her poststroke spasticity. Although the patient reported resolution 4 wks later, clinical evaluations suggested an even longer time course. The patient then experienced the same contralateral symptoms again more than a year later, after a 500-unit injection, which took a similar length of time to resolve.
