Objectives: This study aimed to investigate the effect of upper extremity coordination exercises based on fatigue prediction on fine and gross manual dexterity, upper limb motor function, shoulder and elbow proprioception, occupational performance, and activities of daily living in chronic stroke survivors. Methods: In this pilot double-blind randomized clinical trial, 24 chronic strokes were ...

Temporary deafferentation of the upper limb, with ischemic or anesthetic nerve block, has rapid effects on sensorimotor cortex. Cutaneous anesthesia of the forearm has recently been found to improve sensory and motor function of the paretic hand in chronic stroke patients. However, the neurophysiological mechanisms are unknown. The aim of this study was to investigate the behavioral and neuroph...

Key words: swimming, diving, moving in 3 dimensions, mimicking, song, dance, prosody, articulate language, semi-aquatic past. Articulate language depends on very different abilities, such as vocal dexterity, vocal mimicking and the acquirement by children of the very different and arbitrary phonology and grammatical structure of any language. A vast array of experiments confirm that children ac...

The concept of dexterity and its dimensions have been difficult to define through the years, and various research communities have different definitions of dexterity. In this paper, we present a novel approach to understand people’s perception of dexterity and its different dimensions in daily tasks. The approach entails a video-based survey where people score different tasks along pre-specifie...

OBJECTIVE This study reviews the usefulness of surgical improvement of arm and hand function in patients with non-traumatic spinal cord injury who differ significantly from individuals with post-traumatic tetraplegia with respect to age, injury pattern, gender and socio-economic factors. DESIGN Case series. Tests were conducted preoperatively and 12 months postoperatively. PATIENTS The resu...

In this paper, three translational parallel manipulators, i.e., the RAF, the 3UPU and the Delta, are analyzed for dexterity and workspace. First, the geometric models for these three robots were investigated to determine their respective workspaces. The kinematic models are also derived to calculate the global dexterity of each robot. A multi-objective optimization, where the global dexterity i...

OBJECTIVE This study aimed to examine the relationship between fine and gross motor skills and cerebral palsy-specific quality-of-life in ambulatory children with cerebral palsy. DESIGN Thirty-nine children with cerebral palsy (29 boys, 10 girls; mean age ± SD, 8.8 ± 2.3 yrs) classified under Gross Motor Function Classification System Level I or II were enrolled. Health-related quality-of-lif...
