Subcision is a surgical technique used mostly to manage depressed scars. Over time, many modifications to this surgical technique have been made by various surgeons in order to make it simpler and more effective. We report here a new technique that aims to combine the privilege of the prevention of penetrating the skin beyond the scar and maintaining a horizontal orientation, while taking the a...

The ability to share time and to shift attention between bimanual simultaneous motor tasks were studied in 18 patients with Parkinson's disease (PD) and 19 age- and intelligence-matched controls. The task consisted of drawing triangles with the dominant hand and squeezing a rubber bulb with the nondominant hand. Motor performance was measured using the variables: amplitude of squeezing, frequen...

Affordances--possibilities for action--are constrained by the match between actors and their environments. For motor decisions to be adaptive, affordances must be detected accurately. Three experiments examined the correspondence between motor decisions and affordances as participants reached through apertures of varying size. A psychophysical procedure was used to estimate an affordance thresh...

When comparing handwritten documents concerning disputed authorship, the examiner is responsible for applying a reasonable explanation to an observed significant difference* between features as part of the forming of an expert opinion of identification. This article discusses the features attributed to the use of the left hand and the oppositeor non-dominant hand.. * A significant difference is...

BACKGROUND According to the body-specificity hypothesis, people with different bodily characteristics should form correspondingly different mental representations, even in highly abstract conceptual domains. In a previous test of this proposal, right- and left-handers were found to associate positive ideas like intelligence, attractiveness, and honesty with their dominant side and negative idea...

OBJECTIVE To determine the impact of a single, 3-day intervention on empathy levels as measured by the validated Jefferson Scale of Empathy-Health Profession Students version (JSE-HPS). METHODS Forty second-year student pharmacists were recruited to participate in a non-blinded prospective study. Subjects were randomized to an intervention group (n=20) or control group (n=20) and completed th...

This study was conducted with older adults living in a long-stay institution in the city of Foz do Iguacu, Parana, Brazil with the objective of assessing the influence of muscle strength loss in the risk of falls. The sample consisted of 65 elderly who walk without the aid of support for locomotion, 37 women and 28 men, aged between 67 and 80 years. The risk of falls was assessed through the TU...

OBJECTIVE Long-range temporal correlations (LRTC) of EEG amplitude fluctuations in adults reveal power-law statistics and have been interpreted within the framework of self-organized criticality (SOC). In physical systems states of self-organized criticality showing power-law statistics take time to develop. In this paper we have sought evidence for the idea that brain development tends towards...

How children pick up a tool reveals their ability to plan an action with the end goal in mind. When presented with a spoon whose handle points away from their dominant hand, children between infancy and 8 years of age progress from using an awkward ulnar grip that causes food to spill from the spoon to consistently using a radial grip. At 4 years of age children's grip strategies are highly var...

  Background: Multiple Sclerosis (MS) is the most common disabling neurological disease. Hand dysfunction is one of the main complaints of patients with MS. The present study aimed to compare hand dexterity of MS patients with low Expanded Disability Status Scale (EDSS) scores and healthy adults. It also sought to identify the predictors of disability status of patients with MS based on their m...
