BACKGROUND/AIM: Few studies have examined graphomotor skills in children with prenatal alcohol exposure (PAE) or fetal alcohol spectrum disorder (FASD). METHODS: Graphomotor skills were assessed in 108 predominantly Australian Aboriginal children aged 7.5-9.6 years in remote Western Australia using clinical observations (pencil grasp; writing pressure) and standardised assessment tools (the Evaluation Tool of Children's Handwriting; and the Miller Function and Participation Scales - The Draw-a-Kid Game)...

Endobronchial foreign body impaction is a common occurrence, especially in the pediatric population. Bronchoscopic techniques are the standard of care for their retrieval. However, the most distally located foreign bodies are often difficult to retrieve using these techniques. A novel approach using biplane fluoroscopy, with tools usually used for intravascular foreign body retrieval, has been recently described in adults by interventional radiologists. We are the first to report 2 cases in children using this approach for distally impacted endobronchial foreign body retrieval in the cardiac catheterization laboratory...

Unilateral Spatial Neglect (USN) is normally assessed with paper-and-pencil tests. Virtual reality can be an effective neuropsychological tool for a more ecological and functional assessment and rehabilitation of neglect. We developed a 3D Virtual Reality platform - NeuroVirtual 3D - for the assessment and rehabilitation of cognitive deficits, in particular for USN. Within the virtual environments it is possible to interact with virtual objects and execute specific exercises using a Microsoft Kinect. Through the analysis of different grasping tasks it is possible to evaluate in an ecological way the patients' ability to find and handle objects in both sides of the virtual space...

Previous research has shown that unilateral visual neglect is improved when patients are required to actively grasp an object at its center, rather than only pointing to its center. A similar dissociation between pointing and grasping responses has been reported for pseudoneglect, a spatial bias toward the left side of space that is normally exhibited by healthy participants. Among other theories, the two-visual-streams hypothesis has been offered as an explanation for these dissociations. According to this hypothesis, highly practiced actions that are performed under easily available visual input (e...

Action observation typically induces an online inner simulation of the observed movements. Here we investigate whether action observation merely activates, in the observer, the muscles involved in the observed movement or also muscles that are typically used to achieve the observed action goal. In a first experiment, hand and foot motor areas were stimulated by means of transcranial magnetic stimulation, while participants viewed a typical hand action (grasping) or a nonspecific action (stepping over an object) performed by either a hand or a foot...

OBJECTIVE. We investigated differences in handwriting kinetics, speed, and legibility among four pencil grasps after a 10-min copy task. METHOD. Seventy-four Grade 4 students completed a handwriting assessment before and after a copy task. Grip and axial forces were measured with an instrumented stylus and force-sensitive tablet. We used multiple linear regression to analyze the relationship between grasp pattern and grip and axial forces. RESULTS. We found no kinetic differences among grasps, whether considered individually or grouped by the number of fingers on the barrel...

OBJECTIVE: Pencil grasps other than the dynamic tripod may be functional for handwriting. This study examined the impact of grasp on handwriting speed and legibility. METHOD: We videotaped 120 typically developing fourth-grade students while they performed a writing task. We categorized the grasps they used and evaluated their writing for speed and legibility using a handwriting assessment. Using linear regression analysis, we examined the relationship between grasp and handwriting...

AIM: To investigate the impact of common pencil grasp patterns on the speed and legibility of handwriting after a 10-minute copy task, intended to induce muscle fatigue, in typically developing children and in those non-proficient in handwriting. METHODS: A total of 120 Grade 4 students completed a standardised handwriting assessment before and after a 10-minute copy task. The students indicated the perceived difficulty of the handwriting task at baseline and after 10 minutes...

Simple writer's cramp (WC) is a task-specific form of dystonia, characterized by abnormal movements and postures of the hand during writing. It is extremely task-specific, since dystonic symptoms can occur when a patient uses a pencil for writing, but not when it is used for sharpening. Maladaptive plasticity, loss of inhibition, and abnormal sensory processing are important pathophysiological elements of WC. However, it remains unclear how those elements can account for its task-specificity. We used fMRI to isolate cerebral alterations associated with the task-specificity of simple WC...

The effect of lateralized practice on manual preference was investigated in right-handed children. Probing tasks required reaching and grasping a pencil at distinct eccentricities in the right and left hemifields (simple), and its transportation and insertion into a small hole (complex). During practice, the children experienced manipulative tasks different from that used for probing, using the left hand only. Results showed that before practice the children used almost exclusively the right hand in the right hemifield and at the midline position...

PURPOSE: This article describes our clinical experience with a new needle driver (Olympus, Tokyo, Japan), which we have produced to facilitate minithoracotomy or port-access coronary artery anastomosis with the running suture technique. METHODS: The needle driver is 21 cm long, weighs 38 g, and has a grip shaft 1.4 cm in diameter. The device is held like a pencil. A side lever and a revolving disk in the shaft are manipulated with the fingers; a fine needle with a 7-0/8-0 monofilament suture can be grasped/released and driven to penetrate the coronary arterial wall...

OBJECTIVE: The purpose of this study was to determine whether writing tool type and angle of writing surface affect grasp. METHOD: Fifty-one children 23 to 24 months of age who were typically developing drew with a primary marker, colored pencil, and small piece of crayon on a table and an easel. The marker and pencil were presented pointing left, right, and toward the child. The order of writing tool presentation was counterbalanced. Grasps were scored with a 5-point rating system and analyzed with dependent t tests...

In a standard deceptive box procedure, children aged around 3 years typically fail to acknowledge their own prior false beliefs. For example, they judge incorrectly that they had initially thought a Smarties tube contained pencils after discovering these to be the actual content. Wimmer and Hart (1991) showed that children were more likely to answer correctly in a variant of this task known as a "state change", procedure. In this task, they saw that a container held its expected content (so the initial belief was true) before this was exchanged for something atypical...

Performance tests of young children in the age range 18 months to 4 1/2 years have been studied in a sample of 425 children living in an inner city area and a rural market town. Our results show that there is a minimum number of cubes built into a tower related to age which may indicate developmental delay. There is a developmental sequence of pencil grasp, and useful development scales in copying cube models, drawing geometric shapes, and the draw-a-man test. Girls are significantly ahead of boys in drawing skills...

Three groups of nondysfunctional adults were observed for atypical pencil grasps (i.e., nondynamic tripod grasps) used during functional writing situations: 58 occupational therapy students signing out equipment, 314 voters signing for their ballots, and 113 medical students taking a written examination. Among the total right-handed population, the most frequently used grasp was the dynamic tripod grasp (86%). The second most frequently used grasp was the lateral tripod grasp (10%). Other grasps were observed less often (less than 2% of the time)...

This paper describes a hand test consisting of three steps to test the subject's ability to grasp firmly another person's hand to hold a pencil firmly with fingers II-V with straight knuckles and maximally flexed finger joints, while the investigator pulls the pencil to hold on to a piece of paper with a rounded pinch grip between thumb and index finger while the investigator pulls the paper with a rounded pinch grip with submaximal strength. All three steps must be performed with each hand without causing pain...
