In child rehabilitation, there is a need for assessment tools able to detect even small deficits and subtle changes in order toplan and verify the rehabilitative programme. However, as current methods are mainly based on optoelectronic expensiveand non-portable devices, they tend to lack practicality and/or reliability and good validation. We present two cases ofchildren with a specific learning disorder involving writing skills; both received treatment to improve their motor andvisuomotor skills involved in the act of writing. In addition to neuropsychological testing, the assessment included a new noninvasive method, based on quantitative videoanalysis of arm movement during a maze task; moreover, parent and teacherwere interviewed. The low-cost method seems promising, but it seems to measure something different from the perceptionof teachers and parents and from commonly used neuropsychological tests.Keywords: Rehabilitation, child, visuomotor skills, neuropsychological tests.

Background. Wearable physical activity (PA) trackers are becoming increasingly popular for intervention and assessment in health promotion research and practice. The purpose of this article is to present lessons learned from four studies that used commercial PA tracking devices for PA intervention or assessment, present issues encountered with their use, and provide guidelines for determining which tools to use. Method. Four case studies are presented that used PA tracking devices (iBitz, Zamzee, FitBit Flex and Zip, Omron Digital Pedometer, Sensewear Armband, and MisFit Flash) in the field—two used the tools for intervention and two used the tools as assessment methods. Results. The four studies presented had varying levels of success with using PA devices and experienced several issues that impacted their studies, such as companies that went out of business, missing data, and lost devices. Percentage ranges for devices that were lost were 0% to 29% and was 0% to 87% for those devices that malfunctioned or lost data. Conclusions. There is a need for low-cost, easy-to-use, accurate PA tracking devices to use as both intervention and assessment tools in health promotion research related to PA.

Abstract Objective: To examine the frequency of specific learning disorder (SLD) among primary school children of Sarai Alamgir, Pakistan. Methods: The current cross-sectional study was conducted from January to July 2018 in Sarai Alamgir. Multistage stratified sampling technique was used to select the sample from target population (N=914) of school children studying in 3rd and 4th class of six primary schoolsof Sarai Alamgir, Pakistan.Sample of n=837 children was selected through the Taro Yamane formula. Structured Clinical Diagnostic Interviews based on DSM-V (APA, 2013) diagnostic criteria of specific learning disorder were used to collect data. Children were approached in their classes. Screening tool was applied on all selected children to screen out the vulnerable cases. After screening the vulnerable cases, diagnostic criteria of different specific learning disorders were applied on all vulnerable cases. The frequencies and percentages were analyzed to see the frequency  of learning disorder among children. Results:Findings indicate that 174 (20.7%) children were vulnerable to specific learning disorders out of sample of 837 children. Total 13 (7.5%) children were diagnosed as suffering from different specific learning disorders from vulnerable participants. From vulnerable cases, 1(7.7%) childfulfilled the diagnostic criteria of reading impairment, 3 (23.1%) were diagnosed with mathematics impairment, 4 (30.8%) with multiple impairments in mathematics and writing, 1 (7.7%) with multiple impairments in mathematics and reading, 1 (7.7%) with multiple impairments in reading and writing, and 3 (23.1%) children were diagnosed as suffering from multiple impairments in mathematics, reading and writing.

Purpose: The purpose of this study is to better understand the characteristics of the language-related skills of bilingual children with specific learning disorders (SLD). The aim is achieved by analyzing language-related skills in a sample of bilingual (Italian plus another language) and Italian monolingual children, with and without SLD.Patients and methods: A total of 72 minors aged between 9 and 11 were recruited and divided into four groups: 18 Italian monolingual children with SLD, 18 bilingual children with SLD, 18 Italian monolingual children without SLD, and 18 bilingual children without SLD. Each child underwent tests to evaluate different aspects of language skills: lexical and grammar, metalanguage and executive functions.Results: With regard to lexical and grammatical skills, the conditions of SLD and bilingualism both impact naming in terms of total number of errors for words with low frequency of use, while the condition of SLD has an effect on semantic errors for words with low frequency of use. The condition of bilingualism impacts on the total errors for words with high frequency of use and on circumlocution-type errors for words with low frequency of use. There were significant effects of bilingualism and SLD on the metalinguistic test for understanding implicit meaning, and an impact of SLD on phonological awareness was also found.Conclusion: The results suggest that both SLD and bilingualism have an effect on some lexical skills, in particular for words with low frequency of use. Both conditions, bilingualism and SLD, seem to impact on metalinguistic abilities that depend on lexical knowledge. These findings reinforce the importance of improving understanding of the neuropsychological profile of bilingual children with SLD.

Abstract Underwater exploration or inspection requires suitable robotic systems capable of maneuvering, manipulating objects, and operating untethered in complex environmental conditions. Traditional robots have been used to perform many tasks underwater. However, they have limited degrees of freedom, manipulation capabilities, portability, and have disruptive interactions with aquatic life. Research in soft robotics seeks to incorporate ideas of the natural flexibility and agility of aquatic species into man-made technologies to improve the current capabilities of robots using biomimetics. In this paper, we present a novel design, fabrication, and testing results of an underwater robot known as Kraken that has tentacles to mimic the arm movement of an octopus. To control the arm motion, Kraken utilizes a hybrid actuation technology consisting of stepper motors and twisted and a coiled fishing line polymer muscle (TCP FL ). TCPs are becoming one of the promising actuation technologies due to their high actuation stroke, high force, light weight, and low cost. We have studied different arm stiffness configurations of the tentacles tailored to operate in different modalities (curling, twisting, and bending), to control the shape of the tentacles and grasp irregular objects delicately. Kraken uses an onboard battery, a wireless programmable joystick, a buoyancy system for depth control, all housed in a three-layer 3D printed dome-like structure. Here, we present Kraken fully functioning underwater in an Olympic-size swimming pool using its servo actuated tentacles and other test results on the TCP FL actuated tentacles in a laboratory setting. This is the first time that an embedded TCP FL actuator within elastomer has been proposed for the tentacles of an octopus-like robot along with the performance of the structures. Further, as a case study, we showed the functionality of the robot in grasping objects underwater for field robotics applications.
