9 Clinical Trials for Various Conditions
Task-dependent upper limb tremor is a disorder that frequently impairs patients' function and quality of life. Few studies exist that quantify the improvements in motor performance and disability with botulinum toxin (injections). The study team aims to perform an exploratory pilot trial using toxin Type A (Dysport) in 25 patients with task-dependent upper limb tremor, to refine quantitative measures of performance using blinded video analysis, demonstrate efficacy and tolerability of injections, and provide power calculations for a potential future multi-centered double blinded clinical trial.
This study seeks to compare the use of ultrasound and electrophysiologic techniques to target muscles for the treatment of spasticity and focal dystonia of the limbs. The purpose of this study is to investigate the use of two ways of locating the muscle for botulinum toxin (BoNT) injection for the treatment of focal hand dystonia and upper limb spasticity. Electrophysiologic guidance, using electrical stimulation, and ultrasound are the standard ways of locating muscles during a treatment of BoNT injection.
The purpose of the proposed study is to demonstrate the safety and efficacy of the ANS Totally Implantable Deep Brain Stimulation System in the VIM nucleus of the thalamus implanted for the treatment of tremor due to essential tremor. This study will be included in the Pre-Market Approval Application to support the safety of this device in use.
This study is designed to demonstrate the safety and tolerability of the Encora Therapeutics Tremor Mitigation Device in subjects with upper limb tremor caused by Essential Tremor.
Upper limb essential tremor (UL ET) is a movement disorder characterized by postural and/or kinetic tremor. It can cause difficulty with everyday tasks such as writing, pouring, and eating, and patients also experience associated social embarrassment. This study will assess how safe and effective BOTOX is in treating UL ET. Adverse events and change in disease activity will be evaluated. BOTOX is an investigational drug being developed for the treatment of UL ET. Participants are randomly assigned to 1 of the 4 groups, called treatment arms. Each group receives different treatment. There is 1 in 2 chance that participants will be assigned to placebo. Around 174 participants, aged 18 to 80 years with UL ET will be enrolled in approximately 40 sites in North America. Participants will receive BOTOX or placebo injections in Cycle 1 and Cycle 2. In Cycle 3, participants will receive unilateral or bilateral BOTOX injections. Each cycle is 12 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
The purpose of this study is to determine whether a single treatment with administration of NT 201 (botulinum toxin) is superior to placebo (no medicine) for one-sided treatment of essential tremor in the arm (Unilateral Period). Participants will be assigned to the treatment groups by chance and neither the participants nor the research staff who interact with them will know the allocation. The following treatment cycle will investigate the safety and tolerability of two-sided treatment with NT 201 (botulinum toxin) (Open Label Bliaterial Period). All participants will receive NT 201 treatment.
The objective of this study is to assess the efficacy and safety of a single, kinematic-analysis-based intramuscular injection of NT 201, compared with placebo, in moderate to marked essential tremor of the upper limb.
To determine the effects of upper limb forearm cooling on Essential Tremor upper limb tremor using a more practical method of limb cooling through a forearm cold pack.
Essential Tremor (ET) is characterized by tremors affecting the arms. The investigators will examine the effects of non-pharmacological limb cooling on clinical and physiological characteristics in patients presenting with ET at three different temperatures; and will measure changes in tremor amplitude after cooling of the upper limb.
