. Precise behavioral measurements allow the discovery of movement constraints that provide insights into sensory-motor processes and their underlying neural mechanisms. For instance, when humans draw an ellipse on a piece of paper, the instantaneous speed of the pen co-varies tightly with the local curvature of the path. Known as the speed-curvature power law, this phenomenon relates to fundamental questions of motor control. NEW
. We have developed a software app for displaying static curves or dynamic targets while recording finger or stylus movements on Android touch-screen tablets. Designed for human hand movement research, the app is free, ready-to-use, open-source and customizable.

The feeling that a fake (e.g. rubber) hand belongs to a person's own body can be elicited by synchronously stroking the fake hand and the real hand, with the latter hidden from view. Here, we sought t...
For severely paralyzed people, Brain-Computer Interfaces (BCIs) can potentially replace lost motor output and provide a brain-based control signal for augmentative and alternative communication device...
Hand motor impairment is common after stroke but there are few comprehensive data on amount of hand movement. This study aimed to compare the amount of thumb and finger movement over an extended perio...
Motor-evoked potentials (MEPs), elicited by Transcranial Magnetic Stimulation (TMS) over the motor cortex, are reduced during the preparatory period in delayed response tasks. Here we examine how MEP ...
The execution of coordinated hand movements requires complex interactions between premotor and primary motor areas in the two hemispheres. The supplementary motor area (SMA) is involved in movement pr...
Participants in this study will do hand exercises once per day for 16 weeks. The purpose of the study is to determine if hand exercises designed to improve range of movement and strength ...
The study looks at a new treatment for wrist and finger contractures -- a condition where the affected hand is in a "closed" position, with the wrist and fingers stiff and difficult to mov...
A randomized control trial examining the relationship between changes in hand function and brain plasticity following intensive therapy. Two treatment approaches are used: constraint-induc...
To examine efficacy of combined unimanual and bimanual intensive therapy in children with unilateral brain injury. A key question in hemiplegia therapy is whether the affected hand should ...
Traumatic Brain Injury (TBI)patients often suffer from loss of muscle strength in the hand and foot, decrease in coordination and high muscle tone (spasticity). In this study, investigator...
Deformities of the hand, or a part of the hand, acquired after birth as the result of injury or disease.
Practices involved in preventing the transmission of diseases by hand.
The transference of a complete HAND, as a composite of many tissue types, from one individual to another.
Alterations or deviations from normal shape or size which result in a disfigurement of the hand.
A sport consisting of hand-to-hand combat between two unarmed contestants seeking to pin or press each other's shoulders to the ground.
