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 …

Magneto-rheological fluid orthosis for suppressing tremor
Tremor is a common movement disorder that occurs with specific neurological conditions. This condition may seriously impact daily living activities. The aim of the present study is to evaluate the possibility of the development of a wearable technology that is capable of exerting torques at a …

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 …

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. …

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 …

Parkinson's Disease Automated Hand Tremor Analysis from Spiral Images
… thesis is motivated by the exploration of hand tremor symptoms in Parkinson’s patients from the Archimedean Spiral test, 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 …

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. …

Towards Improved Volcano Monitoring via Automatic Classification of Continuous Tremor
… based on Self-Organising Maps was trained on tremor data recorded at Whakaari to understand changes in seismicity throughout different phases of volcanic unrest. The prototype classifier distinguishes between quiescent and unrest signals, focussing the temporal resolution of periods of …

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
Pathological tremor, a common neurological disorder, significantly impacts patients' daily quality of life and causes difficulties 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. …

Modelling and analysis of ER fluid dampers: with application to tremor suppression
The most commonly used definition for human tremor is as an involuntary, roughly sinusoidal oscillation of one or more parts of the body. It has been established that the application of viscous damping can significantly reduce the amplitude of tremor related oscillations, but that the level of …

Adaptive internal model principle-based control for tremor suppression and sinusoidal signal tracking
Tremor is an involuntary rhythmic motion that can significantly affect a person’s ability to perform daily activities. Suppressing tremor without disturbing voluntary motion remains a major challenge in biomedical control. This dissertation presents an adaptive Internal Model Principle-based …
