Pencil Grip Patterns of Students and Skilled Workers

Background: Pencil grip can be defined via detailed descriptions of the variables constituting the grip and it commences in the preschool years with writing instruments and therefore relevant to graphologists, forensic medicine and anthropology. The purpose of this investigation was to describe the diversity of pencil grip patterns among students and skilled workers in Delta State, Nigeria. The research also aimed at determining the effects of sociodemographic factors, handedness,and handwriting speed on pencil grip patters. Methods: Stratified random sampling was employed in this cross sectional observational study. Five hundred and fourty three volunteers between the ages of 11-77 years were investigated. Students were observed while writing from their textbooks and skilled workers were observed writing from any available news paper. Photograph of the writing hand was captured with the digital canon camera. The data was analysed using the Statistical Package for Social Sciences (SPSS) 20. Kruska wallis test was used to establish relationship between pencil grip patterns and sociodemographic factors. Handwriting speed was determined by a speed score (letters per minute) and timed for 60 secounds for each participant. A self administered questionnaire was used to obtain data on sociodemographic factors. Results: This investigation demonstrates that gender had a significant effect on pencil grip patterns among secondary students (p<0.05)(K.W=7.54. df=1. p=0.01). Further observation showed that age and profession had a significant effect on pencil grip patterns among skilled workers at p<0.05 (K.W= 43.09,134.69 ,df=3,3, p=0.00,0.00). Conclusions: Findings from this investigation present the dynamic tripod grip as the most predominant grip pattern in the studied population.

The Twist X-Ray: A Novel Test for Dynamic Scapholunate Instability

Background Scapholunate instability (SLI) is the most common form of carpal instability. Early detection of SLI is imperative as early reconstructive procedures can potentially prevent the natural history of progressive degenerative arthritis. After wrist arthroscopy, magnetic resonance imaging (MRI) remains the next best noninvasive diagnostic option; however, access still remains costly and is often limited in many health care systems worldwide. In this article, we describe a novel device that allows for dynamic X-rays to be taken, accentuating the scapholunate (SL) widening. Description of Technique Twist X-ray views are generated by the patient clenching a device that combines the standard clenched fist views with ulnar deviation and supination. The test is easy to perform and functions by combining a higher grip force with the ulnar deviation and pronation effects of the extensor carpi ulnaris tendon, thus accentuating the SL gap in dynamic instability. Patients and Methods We present a series of four patients with dynamic SLI and compare the findings of the Twist X-rays with conventional wrist X-rays series, including standard anteroposterior, lateral, radial, and ulna deviation, clenched fist, and pencil grip views. Results In all the four patients, there was substantial dynamic SL widening. The SL interval increased from a mean of 1.8 mm (range: 1.5–2.8) on posteroanterior X-rays to 6.3 mm (range: 4.6–8.2) with the Twist views. Interestingly, on the pencil grip view, the mean widening was only 1.5 mm (range: 1–2.8 mm). Conclusion The authors describe a novel device that allows for improved detection of dynamic SL ligament instability when performing stress X-ray views of the wrist. Level of Evidence This is a Level IV study.

Helping Struggling Writers

Assistive Technology (AT), in the domain of special education, is defined as both tools and services. This chapter provides a description of this definition, what recent national and international writing assessment results indicate, what the characteristics of struggling writers are, and how AT can help these children improve and manage the complex and interdependent task of creating prose, story writing in particular. Key examples of AT services are Self-Regulated Strategy Development (SRSD: a step-by-step process for teaching a student a strategy) and mnemonic strategies (the use of keywords to help a child retain the steps in managing a task such as story writing). In the context of writing, AT can range from a pencil grip to a complete computer system with writing-assistance software. Furthermore, the author reviews his own research studies about story writing and how integral AT is to helping these children. Finally, the need for students' pre-requisite practice with AT is emphasized.
