Essential Tremor Suppression with a Novel Anti-Tremor Orthosis: A Randomized Crossover Trial. Essential tremor (ET) is characterized by action tremor of the arms, which can interfere substantially with daily activities. Pharmacotherapy may be ineffective or associated with side effects, and stereotactic surgery is invasive. Hence, new accessible treatment options are urgently needed. An easy -to-use and lightweight orthotic device that exerts joint damping may provide an alternative solution for reducing tremor in daily activities. Our goal was to assess the efficacy of a novel anti-tremor orthosis (STIL) in reducing clinical and accelerometry measures of distal arm tremor in ET. In a randomized crossover single-blinded trial in 24 ET patients in a hospital setting, we compared three
Targeting the fundamentals for tremors: the frequency and amplitude coding in essential tremor. Essential tremor (ET) is one of the most common movement disorders with heterogeneous pathogenesis involving both genetic and environmental factors, which often results in variable therapeutic outcomes. Despite the diverse etiology, ET is defined by a core symptom of action tremor, an involuntary rhythmic movement that can be mathematically characterized by two parameters: tremor frequency and tremor amplitude. Recent advances in neural dynamics and clinical electrophysiology have provided valuable insights to explain how tremor frequency and amplitude are generated within the central nervous system. This review summarizes both animal and clinical evidence, encompassing the kinematic features
Effect of a Wrist Harmonic Liquid Tremor Absorber-Damping on the Upper Extremity Essential Tremor. Essential tremor (ET) is a common type of tremor. Previous research has shown that wearable orthoses and biomechanical loading methods can suppress tremors. This study aims to investigate the effect of a harmonic liquid dampener on upper extremity ET. The study involved 9 women and 5 men from a neurology outpatient clinic. A 285-g liquid-based harmonic dampening wristband was used. Tremors were recorded from the wrist along the x-y-z axes using a vibrometer, and the Bain-Findley Rating Scale (BFRS) was employed for assessment. BFRS scores significantly improved after the wristband was used (mean difference 35.64, P = 0.001, Cohen's d effect size =2.979). The tremor amplitude decreased

Effects of essential tremor on longevity and mortality rates in families. Essential Tremor (ET) is a common movement disorder characterized by action tremors, primarily affecting the hands and head. lthough previous studies have suggested potential links between ET and aging-related diseases, its relationship with longevity remains unclear, with conflicting evidence in the literature
Double lesion MRgFUS thalamotomy for essential tremor: 4.5-year outcomes and framework for assessing loss of efficacy and tremor progression. The essential tremor (ET) course to 54 months post-unilateral VIM/PSA magnetic resonance-guided focused ultrasound (MRgFUS) in the treated arm (TA) and non-treated arm (NTA) of 12 patients is reported. Tremor severity was rated using Bain Findley at consecutive assessments or between 1 and 54 months, while the NTA BFS scores worsened between 12 and 24 months ( < 0.003). Three patients showed worsening of their TA BFS scores and an increasing NTA-TA BFS difference, indicating slower tremor worsening in TA compared to NTA, whilst one patient showed a greater rate of worsening in the TA compared to NTA BFS. After 54 months, the beneficial effect of MRgFUS
Cortico-thalamic tremor circuits and their associations with deep brain stimulation effects in essential tremor. Essential tremor (ET) is one of the most common movement disorders in adults. Deep brain stimulation (DBS) of the ventralis intermediate nucleus (VIM) of the thalamus and/or the posterior subthalamic area (PSA) has been shown to provide significant tremor suppression in patients multiple cortical and subcortical areas, but its exact mechanisms remain unclear. By simultaneously capturing neural activities from motor cortices and thalami, and hand tremor signals recorded via accelerometers in fifteen human subjects who have undergone lead implantations for DBS, we systematically characterized the efferent and afferent cortico-thalamic tremor networks. Through the comparisons
Propranolol Reduces Parkinson's Tremor and Inhibits Tremor-Related Activity in the Motor Cortex: A Placebo-Controlled Crossover Trial. Parkinson's disease (PD) resting tremor is thought to be initiated in the basal ganglia and amplified in the cerebello-thalamo-cortical circuit. Because stress worsens tremor, the noradrenergic system may play a role in amplifying tremor. We tested if and how propranolol, a non-selective beta-adrenergic receptor antagonist, reduces PD tremor and whether or not this effect is specific to stressful conditions. In a cross-over, double-blind intervention study, participants with PD resting tremor received propranolol (40 mg, single dose) or placebo (counter-balanced) on 2 different days. During both days, we assessed tremor severity (with accelerometry) and tremor

Tremor assessment scales before, during and after MRgFUS for essential tremor - results, recommendations and implications. neurosurgical interventions such as MR-guided focused ultrasound (MRgFUS) are increasingly deployed for treatment of essential tremor. to make recommendations for monitoring treatment effects during and after MRgFUS based on our investigation of correlations between different scales of tremor severity. twenty-five clinical assessments were collected from thirteen patients before and after unilateral MRgFUS sequential lesioning of the thalamus and posterior subthalamic area for alleviating essential tremor. Scales included Bain Findley Spirography (BFS), Clinical Rating Scale for Tremor (CRST), Upper Extremity Total Tremor Score (UETTS) and Quality of Life
