UNLABELLED BACKGROUND AND PURPOSE; Previous work indicated that patients within 1 month of parietal or posterior frontal damage are often abnormally slow or clumsy when using the ipsilateral hand for dexterity tasks. This article reports a 6-month follow-up study to assess recovery and the impact on functional outcome. METHODS Twenty-four patients (80%) were available for follow-up. They used...

Complex hand dexterity is fundamental to our interactions with the physical, social, and cultural environment. Dexterity can be an expression of creativity and precision in a range of activities, including musical performance. Little is understood about complex hand dexterity or how virtuoso expertise is acquired, due to the versatility of movement combinations available to complete any given t...

Evolutionally, development of the direct connection from the motor cortex to spinal motoneurons [corticomotoneuronal (CM) pathway] parallels the ability of hand dexterity. Damage to the corticofugal fibers in higher primates resulted in deficit of fractionated digit movements. Based on such observations, it was generally believed that the CM pathway plays a critical role in the control of hand ...

IMPORTANCE Currently there are few validated metrics for predicting surgical skill among otolaryngology residency applicants. OBJECTIVE To determine whether manual dexterity aptitude testing in the form of soap carving during otolaryngology residency interviews at Kaiser Permanente Medical Center Oakland predicts surgical skill at the time of graduation from otolaryngology residency programs....

Children spend a large proportion of their school day engaged in tasks that require manual dexterity. If children experience difficulties with their manual dexterity skills it can have a consequential effect on their academic achievement. The first aim of this paper was to explore whether an online interactive typing intervention could improve children’s scores on a standardised measure of manu...

Purpose State: An innovative mobile health system called iMHere (interactive Mobile Health and Rehabilitation) has been developed at the University of Pittsburgh to support self-care and adherence to self-care regimens for patients with chronic conditions. The goal of this study is to explore and to identify the accessibility needs and preferences of individuals with dexterity impairments when ...

To control reaching, the nervous system must generate large changes in muscle activation to drive limb toward target, and also make smaller adjustments for precise accurate behavior. Motor cortex controls arm through projections diverse targets across central system, but it has been challenging identify roles of cortical specific targets. Here, we selectively disrupt cortico-cerebellar communic...

BACKGROUND AND PURPOSE Previous research has reported impaired hand function on the "unaffected" side after stroke, but its incidence, origins, and impact on rehabilitation remain unclear. This study investigated whether impairment of ipsilateral dexterity is common early after middle cerebral artery stroke and explored the relationship to cognitive deficit. METHODS Thirty patients within 1 m...
