Motions or muscles? Some behavioral factors underlying robotic assistance of motor recovery
|
Abstract-Robotics and related technologies have begun to realize their promise to improve the delivery of rehabilitation therapy. However, the mechanism by which they enhance recovery remains unclear. Ultimately, recovery depends on biology, yet the details of the recovery process remain largely unknown; a deeper understanding is important to accelerate refinements of robotic therapy or suggest new approaches. Fortunately, robots provide an excellent instrument platform from which to study re...

Robot-assisted movement training for the stroke-impaired arm: Does it matter what the robot does?
Journal of Rehabilitation Research and Development
; Abstract-Robot-assisted movement training improves arm movement ability following acute and chronic stroke. Such training involves two interacting processes: the patient trying to move and the robot applying forces to the patient's arm. A fundamental principle of motor learning is that movement

Oxidation of ethanol in the brain and its consequences.
Alcohol Research & Health
; Acetaldehyde, a toxic byproduct of alcohol (i.e., ethanol) metabolism, has long been suspected of causing at least some of the central nervous system actions of ethanol. However, the data to support such a hypothesis have been difficult to obtain. One roadblock is the very low blood levels of

Overview: how is alcohol metabolized by the body?
Alcohol Research & Health
; Alcohol is eliminated from the body by various metabolic mechanisms. The primary enzymes involved are aldehyde dehydrogenase (ALDH), alcohol dehydrogenase (ADH), cytochrome P450 (CYP2E1), and catalase. Variations in the genes for these enzymes have been found to influence alcohol consumption,
