ABSTRACT Background Fast bowling in cricket is an important skill that imparts mechanical loads on limbs. The differential loading patterns involved in bowling affect the peripheral limb bone status. Objective To evaluate bone properties using quantitative ultrasound densitometry (QUS), among fast cricket bowlers in comparison with nonathletes. A secondary objective was designed to find correlation between QUS parameters and bonespecific physical activity questionnaire (BPAQ). Methodology A total of 80 subject, 40 fast cricket bowlers of both gender (20 male and 20 female) and 40 nonathletes (20 male and 20 female) were included in our study and all are aged between 20 and 25 years. Bone speed of sound (SOS) was measured bilaterally at the distal radius and the mid tibia using Sunlight OmnisenseTM device. Results There was a significant difference between dominant side and nondominant side radial SOS (p < 0.05) and tibial SOS (p < 0.05) in cricket bowlers favoring dominant radial bone SOS and nondominant tibial bone SOS which was not found in nonathletes. Significant difference in dominant radial bone SOS values (p < 0.05) and nondominant tibial bone SOS (p < 0.05) values existed between cricket bowlers and controls. Positive correlation was found between tibial SOS and past BPAQ in all subjects. Conclusion QUS parameters were significantly higher in young cricket bowlers with greater values observed in the dominant arm and leading foot, thus reflecting the osteogenic effect that occurs due to the nature of the game. Further BPAQ is significantly correlated with lower limb bone properties as measured by QUS at mid shaft tibia. How to cite this article Shenoy S, Parthasarathy S, Sandhu JS.

AbstractSeveral studies have reported better clinical outcomes following kinematically aligned total knee arthroplasty (KA-TKA) than mechanically aligned TKA. Consistent reproduction of a KA-TKA is aided by accurate tibial bone resections using computer navigation systems. This study compares an accelerometer-based portable navigation system with a conventional navigation system on tibial bone resection and clinical outcomes in KA-TKA. This study included 60 knees of patients who underwent primary KA-TKA between May 2015 and September 2017. They were randomly assigned to the OrthoPilot and iASSIST groups. A tibial bone cut was performed with 3 degree varus and 7 degree posterior slope in relation to the mechanical axis in all cases. The tibial component angle (TCA) and posterior slope angle (PSA) were evaluated by postoperative radiography, and those that deviated more than 2 degree were set as outliers. The clinical outcomes were the knee range of motion (ROM) and 2011 Knee Society Score (KSS) evaluated at 1 year postoperation. The groups were compared in terms of the TCA, PSA, number of outliers, ROM, and 2011 KSS (p < 0.05). No significant difference was observed between the groups in terms of the mean TCA, PSA, number of outliers, ROM, and categories of the 2011 KSS (objective knee indicators, symptoms, satisfaction, expectations, and functional activities). Although tibial bone cuts were performed with 3 degree varus and 7 degree posterior slope, no significant difference was observed between the OrthoPilot and iASSIST groups in terms of the accuracy of cuts or postoperative clinical result. The iASSIST was found to be a simple and useful navigation system for KA-TKA.

Objective.The current study attempted to identify and characterize distinct CP subgroups based on their level of dispositional personality traits. The secondary objective was to compare the difference among the subgroups in mood, coping, and disability.Methods.Individuals with chronic pain were assessed for demographic, psychosocial, and personality measures. A two-step cluster analysis was conducted in order to identify distinct subgroups of patients based on their level of personality traits. Differences in clinical outcomes were compared using the multivariate analysis of variance based on cluster membership.Results.In 229 participants, three clusters were formed. No significant difference was seen among the clusters on patient demographic factors including age, sex, relationship status, duration of pain, and pain intensity. Those with high levels of dispositional personality traits had greater levels of mood impairment compared to the other two groups (p<0.05). Significant difference in disability was seen between the subgroups.Conclusions.The study identified a high risk group of CP individuals whose level of personality traits significantly correlated with impaired mood and coping. Use of pharmacological treatment alone may not be successful in improving clinical outcomes among these individuals. Instead, a more comprehensive treatment involving psychological treatments may be important in managing the personality traits that interfere with recovery.

Kinesiology Tape

Objectives: Kinesiology tape (KT) is thought to provide greater mechanical support during physical activity, however, there is a paucity of research investigating its application in dance. The study aimed to determine whether KT reduces PlayerLoad (PL) during the Dance Aerobic Fitness Test (DAFT) in addition to examining the relative sensitivity of accelerometer site locations. Methods: University-level dancers (N = 11; age 18 ± 0.45 years, height 168.17 ± 12.25 cm, body mass 57.50 ± 9.91 kg) participated in two trials of the DAFT protocol in two conditions: no tape (NT) and kinesiology tape (KT). Global positioning systems (GPS) and accelerometer units were attached onto the seventh vertebra (C7) at the mid-scapula region and lower limb (LL) located at the mid-gastrocnemius of the dominant leg calculating measurements of triaxial (PLTotal) and uniaxial measures (anteroposterior [PLAP], mediolateral [PLML], and vertical [PLV]) measures of PlayerLoad during the DAFT. Results: No significant main effect was observed for the taping condition in all measures of PlayerLoad (P > 0.10). A significant main effect (p < 0.01) was observed for unit location and time, with greater loading at the LL compared to C7 and during each consequent stage of the DAFT. No significant (p > 0.52) location*taping, nor location*taping*time (p > 0.36) interactions were observed for all variables measured.Conclusions: Kinesiology tape does not reduce loading patterns in healthy dancers during a fatigue protocol. However, triaxial accelerometers provide adequate sensitivity when detecting changes in loading, suggesting the LL may be deemed as a more relevant method of monitoring training load in dancers.

Writing is considered a very important learning tool for all content areas. There is no doubt that writing skill is essential for any kind of learning either at the school or the university level. Therefore, the present study attempted to explore the possibility of improving university students’ one of writing sub-skills, known as coherence through emoji. Coherence in the students’ writing was measured according to the students ability to a) use repetition to link ideas, sentences, and paragraphs, b)use transitional expressions to link ideas, sentences, and paragraphs, c) use pronouns to link sentences, d)use synonyms to link ideas and create variety, e) use parallel structures to link ideas, sentences, and paragraphs. The sample of this study was randomly selected from the Third Level female students joining the Department of English at one Saudi public university. The selected subjects were assigned randomly into control group and experimental group. After administrating the pretest for the two groups, the experimental group was given a six-week treatment of emoji meant for improving the writing sub-skill, while the control group was taught writing without using emoji. One week after the treatment, a posttest was administered to the two groups. Results revealed significant difference between the students’ scores in writing in favor of using emoji to improve students’ writing skills. Thus, the findings show the effectiveness of using emoji in improving students’ coherence in writing. The results were used to draw some conclusions and to suggest some recommendations for teaching writing using emoji. The results also recommend further researches to be done on using emoji to improve other language skills and sub-skills.

Abstract Background The effect of pregnancy and breastfeeding on a female’s bone mineral density (BMD) is controversial. This prospective study aims to investigate the effect of parity on BMD among pre-menopausal multiparous females using quantitative ultrasound as a screening method and females with no pregnancies (nulliparous) as a control group. Methods A portable ultrasound-based bone densitometer (DMS PEGASUS SMART, Mauguio, France) was used to indirectly assess the BMD in 51 multiparous (29–45 years) and 51 nulliparous Arabic females (18–35 years) by quantifying the broadband ultrasound attenuation (BUA) from their right calcaneus bone. BUA > 70 db/mhz = normal, BUA 65–69.9 db/mhz = below average, BUA 55–64.9 db/mhz = osteopenia and BUA < 55 db/mhz = osteoporosis. Results There was a significant difference in mean BUA between multiparous and nulliparous females (74.1 db/mhz vs. 69.3 db/mhz, p = 0.006). The prevalence of normal BMD was significantly higher in the nulliparous group than in the multiparous group (70.6% vs. 47.1%, p = 0.02). Osteoporosis was found in the multiparous group only (3/51). Among the multiparous females who breastfed (43/51), a total of 51.2% (22/43) had normal BMD, 25.6% (11/43) had BMD below average, 18.6% (8/43) had osteopenia and 4.7% (2/43) had osteoporosis. No significant differences in mean BUA (p = 0.2) were found between the group of females who breastfed for one year (13/43; BUA: 70.5 ± 9.4), the group of females who breastfed for 6–11 months (8/43; BUA: 70.6 ± 10.0) and those who breastfed for less than six months (22/43; BUA: 71.6 ± 9.4). A binary logistic regression model built for predicting BMD normality showed significance for the variable parity (p = 0.03), while the effect of the possible confounding variables BMI and age on BMD normality was found to be non- significant (p = 0.1 and p = 0.6, respectively). Conclusion Parity affects the BMD, as assessed by a portable ultrasound-based bone densitometer, of young and middle-aged females as compared to the BMD of nulliparous females.

This study investigated whether Japanese university EFL learners’ listening comprehension differed significantly on tests of authentic language (AL) or scripted language (SL). Possible differences in comprehension between low and intermediate proficiency students, and how lexical density of the listening samples correlated with listening comprehension, were also explored. Participants scored higher on SL multiple choice tests than on AL tests on average. There was no significant difference in the performance between low and intermediate proficiency students in this study, but there was a significant difference between scores of learners in the two pre-intermediate groups. The inclusion of more content words also appeared to aid the lowest performing students in better understanding authentic listening passages. The researcher suggests explanations for these findings, and suggests the need for more authentic listening practice in language classrooms. 本論は日本人EFL大学生のリスニング力が、オーセンティック・ランゲージ（AL）のテストあるいはスクリプト・ランゲージ（SL）のテストにおいて大きく異なるかどうかを調査したものである。初・中級者間における理解力の相違の可能性や、リスニング・サンプルの語彙密度とリスニング力の関係も調査した。SL多肢選択テストの得点の方がALテストよりも平均して高かった。初・中級者間には有意差はなかったが、2つの準中級学習者群間の得点には有意な相違が認められた。また、内容語をより多く含めることは英語力の低い学習者がオーセンティックなリスニング題材を理解する助けになっているようであった。これらの研究結果に対する説明と、よりオーセンティックなリスニング練習の必要性についても述べる。
