Filter by:Fasciculations are clinically defined as spontaneous intermittent contractions of a portion of muscles. Depending on associated symptoms they may be a sign of lower motor neuron disorder. The aim of this study is to investigate if fasciculations also occur in muscles after caffeine consumption and if there is a difference between the muscles of the arms and legs. The primary endpoint is detecting fasciculations in the muscles of the arms and legs after the consumption of caffeine in healthy adults (20-35 years old and 35-50 years old) Secondary endpoints of the study compares the proportions of fasciculations between two age groups (20-35 years old and 35-50 years. A population of 26 subject per group and a total of 52 subject will be recruited for the study. A sample size of 26 in each group will have 90% power to detect a difference between the two groups using a Fisher's exact test with a 0.05 two-sided significance level. Study Intervention Study participants will consume caffeine (6mg per kilogram bodyweight) before the second ultrasound screening. Using ultrasound the sternocleidomastoideus, biceps brachii, interosseus dorsalis, quadriceps femoris, gastrocnemius and abductor hallucis will be measure for 120 seconds 1o minutes before and 45 minutes after caffeine consumption. Study Duration and Schedule Estimated duration for the study will be around 6 months.
Succinylcholine is currently the only depolarizing neuromuscular blocker widely used in anesthesia induction and is the drug of choice for rapid sequential anesthesia induction. However, with succinylcholine, varying degrees of muscle fibrillation and muscle pain occur. Intravenous injection of succinylcholine caused by myomuscular fibrillation can cause increased intragastric pressure, intraocular pressure and intracranial pressure, increased serum potassium and postoperative myalgia, increased the incidence of adverse events such as needle prolapse, extravasation of injected drugs, and reduced perioperative comfort of patients. Pretreatment with cisatracurium provides limited prevention of muscular fibrillation due to succinylcholine, but the choice of dose often depends on user experience, and there have been no previous studies of age-related doses of cisatracurium for the prevention of muscular fibrillation caused by succinylcholine, and its half-effective amount (ED50) has not been established. In this study, patients treated with elective general anesthesia surgery were the subjects, and in the process of general anesthesia induction, cis-atracurium was pretreated to evaluate the degree of inhibition of muscular fibrillation caused by succinylcholine, and half of the effective dose of cis-atracurium inhibition of muscular fibrillation caused by succinylcholine was calculated by sequential method.
Patients with motor neurone disease (MND) typically experience relentless motor decline and die within three years of symptom onset from respiratory muscle weakness. There are currently no effective therapies and the discovery of novel therapies is hampered by the lack of a sensitive disease biomarker. Consequently, there is a huge drive to discover novel biomarkers, which can reliably track disease progression over time. These can then be incorporated into clinical drug trials to expedite effective drug discovery. Muscle fasciculations represent the hyperexcitability of diseased motor neurons and are almost universally present from the early stages of MND. The investigators predict that the site, frequency and shape of fasciculations might provide a sensitive measure of disease progression in an individual. In order to calibrate this technique, the investigators will conduct a 12-month longitudinal study, recruiting 24 patients from the King's College Hospital Motor Nerve Clinic, comprising a mixture of patients with MND and those with benign fasciculation syndrome. Patients in this latter group have fasciculations but do not develop weakness and have normal lifespans. They are therefore an optimal control group. At each visit, the investigators will take resting HDSEMG recordings from all four limbs and perform standard clinical measures of disease progression. The investigators will also monitor the decline in motor unit number using a newly validated neurophysiological technique, called Motor Unit Number Index (MUNIX).
The FLX-787-106 study will determine how well FLX-787-ODT works to reduce fasciculations in patients with Amyotrophic Lateral Sclerosis (ALS). The study will measure how often fasciculations occur, and monitor any side effects that might develop while taking the investigational product. Participants will be assessed before and after taking a single dose of FLX-787-ODT. Approximately 15 people will take part in this study at one center in the United States. Participants will be in the study for a single clinic visit and receive a telephone call 7 days later to monitor for side effects.
The FLX-787-107 study will determine how well FLX-787-ODT works to reduce fasciculations in patients with Amyotrophic Lateral Sclerosis (ALS). The study will measure how often fasciculations occur, if tongue and muscle strength, speech, and swallowing are affected, and monitor any side effects that might develop while taking the investigational product. Participants will be assessed before and after taking a single dose of FLX-787-ODT. Approximately 15 people will take part in this study at one center in the United States. Participants will be in the study for a single clinic visit and receive a telephone call 7 days later to monitor for side effects.
To investigate the effects of different doses of cisatracurium pretreatment on succinylcholine-induced fasciculations.
The purpose of this study is to investigate the effects of different doses of cisatracurium pretreatment on succinylcholine-induced fasciculations and postoperative myalgia.
Succinylcholine is commonly used for neuromuscular relaxation for short procedures such as rigid bronchoscopy. A more modern alternative is the application of low-dose rocuronium, reversed by low-dose sugammadex. The investigators compare the intubating conditions, incidence of postoperative myalgia (POM), as well as patient satisfaction for these two muscle relaxants.
