Alternating Current Stimulation for Essential Tremor
Essential tremor is the most common movement disorder, characterized by involuntary rhythmic shaking of the hands, head, trunk, vocal cords, or legs. While the pathophysiological mechanisms of essential tremor are not fully understood, research suggests the involvement of a complex network called …

Assessment and modulation of essential tremor using peripheral-nerve stimulation
Tremor is an abnormal oscillatory movement, observed in patients with essential tremor (ET), Parkinson’s Disease, and other neurological disorders. ET obstructs patient’s movements that require high degrees of dexterity and precision, resulting in a reduction of the quality of life for the patient. …

Quantifying the pathways modulated by deep brain stimulation for essential tremor using computational modeling
… a therapeutic effect on postural and kinetic tremor in patients with Essential Tremor (ET). For patients with DBS leads placed near the caudal border of Vim, however, there is an increased likelihood of inducing paresthesias through activation of the sensory ventral caudal (Vc) nucleus of …

The effects of changing head position and posture on head tremor in individuals with essential tremor involving the head
… of different postural control demands on head tremor measures in participants with essential tremor. Methods: Seventeen participants with essential tremor (ET) of the head and 17 control participants took part. Individuals held their heads in varying degrees of rotation, flexion, and extension. …

Active tremor control of human motion disorder
… subject to a physiological phenomenon known as tremor, which introduces unintended, relatively high-frequency movements into various parts of the body. These unintended movements serve to limit human motor performance with respect to normal human performance (for cases in which tremor is …

Development of positioning devices for MRI-guided high intensity focused ultrasound (HIFU) for abdominal, thyroid and brain, tumours
… and brain disorders such as Parkinson’s disease, essential tremor, and neuropathic pain. These optimistic investigations have encouraged physicians and provided them new valuable tools for medical research.

Chronic Monitoring and Longitudinal Efficacy of Neuromodulation for Neurological Movement Disorders
… we compare several aDBS algorithms for managing essential tremor symptoms. We also show that the beta band biomarker used to decode movement is sufficiently stable over time fo the aDBS paradgim to remain effective for many months. In a second implementation focused on live distributed data …

Design and validation of chronic research tools for an implantable closed-loop neurostimulator
… for the treatment of Parkinson's Disease, Essential Tremor and Dystonia, and are in clinical evaluations for Epilepsy and Depression. Despite the success of DBS therapy, the current systems are open-loop, where the clinician is the sensor and control algorithm, and hence these are …

Monoaminergic Signaling in the Human Brain: New Insights
… experiment, patients with Parkinson's disease or essential tremors played a social reward task. We observed opponency between dopamine and serotonin to positive prediction errors in patients with essential tremor, but not in those with Parkinson's disease. Moreover, patterns of dopaminergic and …

Prevalence and diagnosis of Parkinson's disease: a community study
… Conditions commonly misdiagnosed as PD include Essential tremor (ET), vascular Parkinsonism (VP) and dystonic tremor (DT). This thesis examines the accuracy of clinical diagnosis of PD in a community setting by identifying misdiagnosed cases and supervising antiparkinson medication withdrawal. …

Methods for Physiologic Tremor Characterization, Mitigation, and Modeling
Physiologic tremors exist in all healthy individuals, and occur in moments of excitement, anxiety, or muscle activation. They have been commonly observed in surgeons and other occupations requiring precise movements, but unlike tremors from Parkinson’s disease or Essential Tremor, they are often …

A qualitative exploration of the movement disorder experience
… research study exploring the lived experience of essential tremor. Using interpretative phenomenological analysis as the specific method, nine participants were interviewed and the data analysed. Three major themes were constructed: “But they often look at you like you’re some drug addict or smack …

Optimizing the neural response to electrical stimulation and exploring new applications of neurostimulation
… motor disorders, such as Parkinson's disease and essential tremor. Alcohol use disorder, and addictive disorders in general, is a prevalent condition that is difficult to treat long-term. To determine whether DBS can reduce alcohol drinking in animals, voluntary alcohol consumption of …

Intrapersonal Grief as a Clinical Entity Distinct from Depression: Does It Exist Among a Medically Ill Parkinson's Disease Population?
… hundred and ten Parkinson's disease and Essential Tremor patients recruited from a VAMC Hospital completed questionnaires at baseline and five to six months later. The Loss Inventory proved to be a reliable and a valid measure of intrapersonal grief. Principal components analysis …

Analysis and Design of Electrodes for Deep Brain Stimulation
… the brain to treat movement disorders including essential tremor, Parkinson's disease and dystonia. An important goal in the design of next generation DBS electrodes is to minimize the power needed to stimulate specific regions of the brain. A reduction in power consumption will prolong battery …
