One hand, two hands, two people: Prospective sensorimotor control in children with autism

Where grasps are made reveals how grasps are planned. The grasp height effect predicts that, when people take hold of an object to move it to a new position, the grasp height on the object is inversely related to the height of the target position. In the present study, we used this effect as a window into the prospective sensorimotor control of children with autism spectrum disorders without ac...

When two limbs are weaker than one: sensorimotor syncopation with alternating hands.

This study addresses the demands of alternating bimanual syncopation, a coordination mode in which the two hands move in alternation while tapping in antiphase with a metronomic tone sequence. Musically trained participants were required to engage in alternating bimanual syncopation and five other coordination modes: unimanual syncopation where taps are made (with the left or right hand) after ...

Dexterity and two-point discrimination of the hand in school-aged children with dysgraphia

Background: Dysgraphia as a problem with handwriting, affects student’s performance in school activities and participation. The purpose of the study was to compare dexterity and two-point discrimination of the hand between learning disabled students with dysgraphia and healthy students.   Methods: Forty-three students with developmental dysgraphia and 55 normal students in grade t...

Two Task-Specific Dystonias in One Hand

BACKGROUND Dystonia is characterized by involuntary muscle contractions that lead to abnormal postures and/or repetitive movements. Task-specific dystonia only manifests during a specific activity. CASE REPORT We report a case of a female with writer's cramp who developed a second task-specific hand dystonia (tremor and abnormal posturing of the hand while using a computer mouse) many years a...
