OBJECTIVE To assess the prevalence and significance of impaired manual dexterity in hereditary motor and sensory neuropathy type 1a (HMSN 1a), with the Sollerman hand function and the Functional Dexterity test, and compare the reliability and agreement of the tests. DESIGN Descriptive cross-sectional study. SUBJECTS Forty-nine subjects with HMSN 1a. RESULTS Forty-six (94%) subjects had an...

Recent studies have shown that during unimanual motor tasks, aging adults show bilateral recruitment of primary motor cortex (M1), while younger adults show a suppression of the ipsilateral motor cortex. Additional work has indicated that increased bilateral M1 recruitment in older adults may be deleterious when performing some motor tasks. However, higher levels of physical fitness are associa...

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...

BACKGROUND Despite that disability of the upper extremity is common after stroke, there is limited knowledge how it influences self-perceived ability to perform daily hand activities. The aim of this study was to describe which daily hand activities that persons with mild to moderate impairments of the upper extremity after stroke perceive difficult to perform and to evaluate how several potent...

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 two to four from ...

Manual dexterity and hand functional difficulties in daily life in hand-arm vibration syndrome (HAVS) were investigated in 29 male patients with HAVS and 30 male controls without occupational exposure to hand-arm vibration. Manual dexterity was assessed by measuring the performance time of picking up and transferring 30 red beans, one by one, from one plate to another. Vibrotactile perception t...

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...
