Characterization Of Smoothness In Wrist Rotations, Layne Hancock Salmond
Characterization Of Smoothness In Wrist Rotations, Layne Hancock Salmond
Theses and Dissertations
Smoothness is a hallmark of healthy movement and has the potential to be used as a marker of recovery in rehabilitation settings. While much past research has focused on shoulder and elbow movements (reaching), little is known about movements of the wrist despite its importance in everyday life and its impairment in many neurological and biomechanical disorders. Our current lack of knowledge regarding wrist movement prevents us from improving current models, diagnosis, and treatment of wrist disorders. In particular, while movement smoothness is a well-known characteristic of reaching movements and may potentially be used to diagnose and monitor recovery from …
Characterization Of Postural Tremor In Essential Tremor Using A Seven-Degree-Of-Freedom Model, Daniel William Geiger
Characterization Of Postural Tremor In Essential Tremor Using A Seven-Degree-Of-Freedom Model, Daniel William Geiger
Theses and Dissertations
Essential Tremor (ET), a condition characterized by postural and kinetic tremor in the upper limbs, is one of the most prevalent movement disorders. While pharmaceutical and surgical treatment options exist, they are not ideal. Assistive devices have the potential to provide relief to patients but are largely unexplored for ET. Furthermore, prior characterizations of essential tremor have focused on endpoint tremor and provide insufficient detail for designing such a device. We propose and demonstrate a novel method for characterizing essential tremor in the 7 proximal degrees of freedom (DOF) of the upper limb in various postures. In addition, we provide …
