Active clinical trials for "Spasm"

Leg cramps are painful sensations of tightening in the muscles of the legs, that are often associated with secondary insomnia. They are common especially at an older age. There is no evidence that any method of prevention of nocturnal leg cramps would be both safe and effective. There are no previous trials concerning cramp prevention by using compression stockings. The objective of this study is to assess in a prospective randomised controlled trial whether leg cramps can be prevented by daily use of knee-length compression stockings or magnesium supplements.

Transradial cardiac catheterization and percutaneous coronary intervention are increasingly being performed worldwide in elective and emergency procedures, with many centres adopting the transradial route as their first choice of arterial access. One of the most common complications encountered during transradial procedures is radial artery spasm. The aim of this study is to evaluate the Efficacy and Safety of the use of transdermal Glyceryl trinitrate patches applied to skin before cardiac catheterization to prevent the occurrence of radial artery spasm during transradial access cardiac catheterization.

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.

Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).

To determine the clinical manifestation, diagnosis and treatment options of primary hemifacial spasm in Chinese outpatient subjects

Writer's cramp (WC) is a form of focal dystonia, a movement disorder characterized by sustained or intermittent muscle contractions causing abnormal, often repetitive movements, postures, or both. It typically manifests while writing, making handwriting impossible in the most severe cases. Treatment can be difficult, but one effective and well-tolerated treatment consists in local muscle injections with botulinum toxin. Although clinical improvement seems to be related to focal muscle chemodenervation, central plasticity changes may occur. The main aim of the study is to characterize and quantify the changes in intrinsic hand muscle cortical representations at rest and during isometric contractions of the finger muscles before and after treatment with botulinum toxin and the changes in sensorimotor integration in patients with writer's cramp.

The purpose of this study is to create a patient registry to collect and analyze information on subjects treated with Sabril and the prescribers of Sabril.

Infantile Spasms syndrome (ISs) is a characterized by epileptic spasms occurring in clusters with an onset in the first year of life. West syndrome represents a subset of ISs that associates spasms in clusters, a hypsarrhythmia EEG pattern and a developmental arrest or regression. Aetiology of ISs is widely heterogeneous including many genetic causes. Many patients, however, remain without etiological diagnosis, which is critical for prognostic purpose and genetic counselling. In the present study, the investigators performed genetic screening of 73 patients with different types of ISs by array-CGH and molecular analysis of 5 genes: CDKL5, STXBP1, KCNQ2, and GRIN2A, whose mutations cause different types of epileptic encephalopathies, including ISs, as well as MAGI2, which was suggested to be related to a subset of ISs.

This is a randomized, controlled study to compare Short-term ketogenic diet with conventional long-term trial in refractory infantile spasms.

Patients are chosen to participate in this study because they will undergo a particular type of brain surgery to treat their hemifacial spasm. This surgery is called microvascular decompression (MVD) and involves the facial nerve. The facial nerve is being compressed by one or more blood vessels and this contact produces the facial twitches. The investigators do not know why a blood vessel that touches the facial nerve produces facial twitches. The investigators are interested in investigating this during your surgery. A total of 25 participants are expected to participate in this study.
