Human non-hairy (glabrous) skin of the fingers, palms and soles wrinkles after prolonged exposure to water. Wrinkling is a sympathetic nervous system-dependent process but little is known about the physiology and potential functions of water-induced skin wrinkling. Here we investigated the idea that wrinkling might improve handling of wet objects by measuring the performance of a large cohort o...

The architectural design is fundamental in the construction process of a virtual rehabilitation system since it allows to understand components and their interaction, guide develop software. This article proposes dynamic architecture that could be used independently software hardware for motor dexterity. proposal contributes engineering area provides starting point development systems. implemen...

Twelve- and 18-month-old infants participated in a study designed to investigate the quality of their manual action when relating an object to the surface on which it is explored. Specifically, infants' perception-action routines were observed when they were presented with multiple objects (wooden scoop, Velcro block, and crayon) on surfaces of varying properties (paper, sand, and Velcro) to de...

OBJECTIVE To explore circadian variation in pain, stiffness, and manual dexterity in patients with hand osteoarthritis (OA). METHODS Twenty one patients with hand OA, as defined by ACR criteria (17 women, four men, mean age 62.2 years, range 52-74 years) self rated pain and stiffness on separate 10 cm horizontal visual analogue scales and performed bead intubation coordinometry (BIC) six time...

Objectives: Spastic hemiplegia cerebral palsy is the second type of cerebral palsy among pre-mature infants, which affects the mobility of one side of the body by impairing the brain’s ability to send nerve impulse to the muscles. The present research aims to examine the effect of motor training in mirror therapy on the gross motor skills in Spastic Hemiplegia Cerebral Palsy (SHCP) childr...

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...
