Filter by:Our hypothesis is that botulinum toxin injections (with onabotulinum toxin, incobotulinum toxin, and abobotulinum toxin) given at 10-week or shorter intervals for the indication of treatment of muscle spasms associated with neurological disorders are associated with equal safety and effectiveness as those given at 12-week or longer intervals. We also hypothesize that for those patients who would prefer a shorter inter-injection interval, but for whom their insurance carrier has prevented this, have worse health-related quality of life compared to patients who receive injections at a 10-week or shorter interval. We aim to investigate this hypothesis by collecting demographic and injection data and patient survey responses.
The planned study is a prospective analysis of non-psychoactive Cannabidiol (without THC) as an adjunctive therapy for blepharospasm in a masked double cross-over study. This prospective study is a follow-up to a retrospective study completed by the researchers using over-the-counter, self purchased CBD. This study will use FDA approved Cannabidiol medication, Epidiolex, directly from GW pharmaceuticals, rather than self-purchased CBD from the internet. Patients will undergo videorecording with a high resolution videocamera system at days 0, 45, 90, 135, and 180 using a novel blink analysis to gather objective data measurements of changes induced by CBD in Blepharospasm patients. This study will attempt to codify the data and quantify if adjunctive CBD therapy improves those areas compared to botulinum injection alone.
Efficient gait requires effective postural control, both static and dynamic. Hence, postural disorders may affect gait. Yet, very little is known about the specific effects of focal postural disorders such as cervical dystonia (CD) and blepharospasm (BS) on patients' mobility. The present research therefore aims at analyzing gait characteristics in patients presenting with these conditions in order to document possible gait alterations. In addition, the investigators will explore the effect of botulinum toxin treatment, which the most frequently used therapeutic option, on the patients' gait characteristics. Indeed, while the treatment improves both dystonia and pain, and therefore quality of life, its influence on gait is presently unknown. the investigators aim at filling this knowledge gap
This pilot study aims at investigating the role of superior colliculus in patients with idiopathic blepharospasm (BSP) de novo, compared to healthy subjects.
The purpose of this study is evaluate the efficacy and safety of Botulax® in the treatment of Essential blepharospasm.
A triple-masked placebo-controlled trial assessing the efficacy and safety of pretarsal versus preseptal botulinum toxin for patients with eyelid spasm. The investigators hypothesize injection of botulinum toxin into the pretarsal orbicularis oculi muscle will have greater clinical efficacy, better measured quality of life, fewer complications, and better cost effectiveness in comparison to a preseptal pattern of injection.
Idiopathic blepharospasm (IB) is a rare but well characterised adult onset focal dystonia that may cause severe visual disability. The most effective treatment is with periodic injections of botulinum toxin into the pre-tarsal and / or pre-septal orbicularis oculi muscles bilaterally. However, even with treatment, practical visual function often remains compromised. A subset of IB sufferers find that eye opening improves with focal unilateral digital pressure usually on a specific point on the temple. The Investigators have developed a spectacle mounted spring-loaded prosthesis (the "Pressop" device) to apply continuous individually localised focal pressure on the temple to mimic the effect of finger pressure. The Investigators recommended a trial of this simple safe device in those IB patients who report improvement in eye opening with focal digital temple pressure.
This clinical study evaluates the efficacy and safety of Neuronox compared with Botox in adults with essential blepharospasm.
The purpose of this study is to evaluate the Efficacy and Safety of NABOTA in treatment of essential blepharospasm
The aim of this study is to develop new rating scales to help diagnose and measure the severity of blepharospasm. This is a condition involving a lot of blinking and spasms of eye closure that people can't control. This study will also test some video software to see if it can help diagnose people or tell the severity of disease using only a video recording of an exam. There is an additional plan to create an educational video to teach others the proper use of the scale and video software.
