Filter by:Dystonia is the most common movement disorder in the pediatric population after spasticity. It can affect normal motor development and cause significant motor retardation. The presence of dystonia may affect motor function, pain, and ease of care in CP. Additionally, it can cause serious difficulties in daily living activities and social participation and long-term joint deformity. The increase in the severity of dystonia in CP children with secondary dystonia may affect the quality of life, activity and participation of the children, as well as the caregiver. The importance of caregivers is an undeniable fact, especially in these patient groups. This study aims to investigate the burden of dystonia severity on the participation in daily living activities and caregivers of children with CP with secondary dystonia.
Study of Ingrezza (Valbenazine) for the treatment of cervical dystonia.
Vibration applied to the skin has been anecdotally reported to potentially improve motor control in patients with movement disorders including Parkinson's disease, however few devices have been studied formally. In this study, the investigators will test the effect of skin surface vibration applied non-invasively to patients with movement disorders to determine if there are any beneficial effects on common tasks of motor control and/or abnormal motor symptoms in patients with Parkinson's disease (PD), essential tremor (ET), and dystonia.
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.
Botulinum neurotoxin (BoNT) is injected into muscles for treatment of dystonia. BoNTs are zinc proteases, and their enzymatic effect is reduced in the setting of low zinc. The study hypothesis is that a large enough fraction of unselected dystonia patients receiving BoNT injection have suboptimal zinc concentration in their tissues, and will experience improved response to BoNT if the injection is preceded by oral zinc supplementation (OZS). OZS consists of 50 mg of zinc acetate oral tablet each day for 7 days before injection. This is a double blind placebo controlled cross-over study, randomized order placebo and OZS, in patients at a neurology clinic on stable dose of BoNT.
Dystonia is a chronic neurological condition that impacts the quality of life due to decreased mobility, social repercussions caused by others's perception of abnormal involuntary movement and frequent pain. Botulinum toxin has been shown to be effective in reducing pain in dystonia. However, many patients remain painful despite the injections, especially when the decrease in the effect of the latter, performed every 3 months on average. Despite frequent use of TENS in pain relief, only a few small studies studying TENS in dystonia were published and none of them reported TENS effects on dystonic pain using sensory threshold. This study aimed to quantify the efficacy and tolerance of TENS in the indication of pain related to dystonia, focusing on cervical dystonia which is the most common form of dystonia.
Dystonia is a disabling symptom affecting both patients with idiopathic Parkinson's disease (PD) and atypical parkinsonism (AP). Botulinum toxinum (BoNT), by blocking muscle contraction, is a possible treatment for focal dystonia. The benefit of BoNT treatment has been proven in some focal dystonia associated with PD or AP. The investigators aim to give an overview of the efficacy of BoNT in a variety of focal dystonia in a large cohort of parkinsonian patients.
We will apply 16 sessions of rTMS over 4 consecutive days for adult patients suffering from cervical dystonia who receive botox on a regular basis. The TMS protocol will take place 9 weeks following their last botox injection. The primary outcome measure will be improvement in cervical dystonia as measured by the TWSTRS scale. The secondary outcome measures include mood, cognition, gait, TMS measures, and high-density EEG measures.
This Open-label Extension trial will evaluate the safety and efficacy of ABP-450 for the treatment of cervical dystonia in adults. The study will enroll 60 patients across approximately 42 sites in the United States from Phase 2 (ABP-19000) and Phase 3 (ABP-19001) trials and 29 sites in Europe from Phase 3 (ABP-19001) trial. Study subjects who had their initial dose of study drug in Phase 2 or Phase 3 trial studies, irrespective of treatment allocation, will be eligible to enroll in this OLE study.
This Phase 2 trial will evaluate the safety and efficacy of ABP-450 for the treatment of cervical dystonia in adults. The study will enroll 60 patients across approximately 30 sites in the United States. Study subjects will be divided evenly across a low dose group, a medium dose group, a high dose group, and a placebo group for one treatment cycle.
