Low power data acquisition for microImplant biometric monitoring of tremors
… of the long term monitoring of Parkinson's tremors. This work investigates how to reduce the amount of data needing to acquire a signal by applying compressive sampling thereby alleviating the demand on the energy source. A low energy SAR ADC is designed using adiabatic charging to further …

Data driven modeling and MPC Based control for Pathological Tremors
… serve as one of the solutions to alleviate these tremors. For improved performance of such devices, we need to solve a few problems, which include developing a model for pathological tremors, and a safe control system that can conveniently incorporate constraints on the wrist's range of motion and …

The nature and enactment of African dance that produces neurogenic tremors
… to many. African dance that produces neurogenic tremors (ADNT) is an occupation that may already be accessible to many, and a potential resource for health and could be used in occupational therapy. Research Question: What is the nature and enactment of ADNT? Aim: The study aimed to explore, …

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 …

Design and Modeling of Parallel Exoskeleton for Wrist Tremor Suppression
… a for patients suffering from Pathological Tremors. Pathological tremors are involuntary, rhythmic, and oscillatory movements that manifest in limbs, the head, and other body parts. Among the existing treatments, mechanical loading through wearable rehabilitation devices is the best way to …

Investigation of Future Voluntary Movement Prediction for Pathological Tremor-Alleviating Exoskeletons
… with performing simple daily tasks. Those tremors usually interfere with the patient's fine motor control and may also cause psychological anxiety and social barriers. Traditional treatments, such as medication and physical therapy, can alleviate symptoms to a certain extent; however, their …

Design and Control of an Ergonomic Wearable Full-Wrist Exoskeleton for Pathological Tremor Alleviation
… for patients suffering from pathological tremors. Pathological tremors are involuntary, rhythmic, and oscillatory movements that manifest in limbs, the head, and other body parts. Among the existing treatments, mechanical loading through wearable rehabilitation devices is popular for being …

Quantification of Motion and Cry Characteristics of NAS Newborns
… who can experience withdrawal symptoms including tremors, poor feeding, and respiratory distress. Presently, the Finnegan Scoring System, a subjective rating scale, is commonly used to judge the patient's condition and determine appropriate treatment methods. This project sought to develop a …

Effects of varying inertial load on human wrist movement
… maximum acceleration and speed, and hand tremors were tested. The frequency content seen in the natural speed trials was found to resemble a normal distribution. This higher area of frequency content could potentially correlate with the frequency of hand tremors. After analysis of …

Parkinson's Disease Automated Hand Tremor Analysis from Spiral Images
… a paper-and-pencil test used to evaluate hand tremors. This work presents a novel Fourier Domain analysis technique that transforms the pencil content of hand-drawn spiral images into frequency features. Our technique is applied to an image dataset consisting of spirals drawn by healthy …

Comparable Effects of Morphine Sulfate and Adrenocorticotropic Hormone in the Midbrain Reticular Formation of Rats
… rotation. Both morphine and ACTH also produced tremors, high excitability, and extreme sensitivity in the injected rats. These findings suggest that morphine and ACTH may act on the same receptor sites in the midbrain reticular formation, resulting in impaired motor behavior on the same side of …

ENCEFALOMIELITE VIRAL EQUINA EM DOIS POTROS NO AGRESTE DA PARAIBA
… (sitting dog position) staggering gait, muscle tremors. A filly also developed difficulty in swallowing. Both had worsening of clinical signs and were submitted to euthanasia. Macroscopic lesions were non-specific and included congestion of the meninges or neurogenic bladder. Histologically, …

Bromethalin-based rodenticides: Mode of action, toxicity, clinical effects, and treatment efficacy in rats, dogs, and cats
… given to dogs resulted in rapid severe muscle tremors and generalized seizures. Bromethalin toxicosis was also associated with increased cerebrospinal fluid pressure and cerebral edema. Bromethalin toxicosis produces acute and chronic EEG changes. Predominant abnormal EEG changes included: …

Neurological Effects of Low-Level, Chronic Domoic Acid Exposure in a Nonhuman Primate Model
… in adults that were manifested as intention tremors (Burbacher et al., 2019). Given that previous studies have found oral doses up to ten times greater than those used in the present study were not overtly toxic, this observation was unexpected (Truelove et al., 1998). The three experiments …

Monoaminergic Signaling in the Human Brain: New Insights
… 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 serotonergic …

Magneto-rheological fluid orthosis for suppressing tremor
… that is wearable and capable of suppressing tremors at the wrist. The proportionality of the tremor-reducing torque to electric current allows the potential for both user adjustment as well as automatic feedback control.

Modeling intrinsically disordered proteins ; a comprehensive study of [alpha]-synuclein
… clinically by motor deficits - namely resting tremors, rigidity, bradykinesia and postural instability - and pathologically by intraneuronal inclusions in the substantia nigra. Several studies suggest that a-synuclein, the major component of these intracellular inclusions, plays a major role in …

An approximate method for the transient response of nonlinear systems
… might arise from sources such as earthquake tremors, wind gust forces and pressure, and pressure waves from explosions. Of the various assumptions which the engineer must make when studying the dynamic response of structures, one of the most important is perhaps the model representation of …

Transgene-free strategies for wireless control of animal physiology using magnetite nanoparticles
… are used to control brain activity and prevent tremors. An idealized version of this therapy would use soft materials and be wireless in order to be minimally invasive and cause minimal damage to brain tissue. Magnetic fields are an appealing candidate for wireless therapies because at many …
