The purpose of this study was to analyze the acute effects of a standardized water training session on the shoulder rotators strength and balance in age group swimmers, in order to understand whether a muscle-strengthening workout immediately after the water training is appropriate. A repeated measures design was implemented with two measurements performed before and after a standardized swim session. 127 participants were assembled in male (n = 72; age: 16.28 ± 1.55 years, height: 174.15 ± 7.89 cm, weight: 63.97 ± 6.51 kg) and female (n = 55; age: 15.29 ± 1.28 years, height: 163.03 ± 7.19 cm, weight: 52.72 ± 5.48 kg) cohorts. The isometric torque of the shoulder internal (IR) and external (ER) rotators, as well as the ER/IR ratios, were assessed using a hand-held dynamometer. Paired sample t-tests and effect sizes (Cohen’s d) were used (p ≤ 0.05). No significant differences were found on the shoulder rotators strength or balance in males after training. Females exhibited unchanged strength values after practice, but there was a considerable decrease in the shoulder rotators balance of the non-dominant limb (p < 0.01 d = 0.366). This indicates that a single practice seems not to affect the shoulders strength and balance of adolescent swimmers, but this can be a gender specific phenomenon. While muscle-strengthening workout after the water session may be appropriate for males, it can be questionable regarding females. Swimming coaches should regularly assess shoulder strength levels in order to individually identify swimmers who may or may not be able to practice muscle strengthening after the water training.

This paper aimed at measuring the impacts of using the process approach to teach second-year English major students at the English Department of Université de Zinder (henceforth, UZ) essay writing. Drawing on the pre-test-post-test repeated measures design, this study examined the written essays produced by the EFL students before and after the writing class. These pre and post tests were scored based on a criterial fair copy, and the scores were compared by means of an Analysis of Variance (ANOVA) to check whether there were any statistically significant differences between the mean scores. The findings revealed that the process approach had a positive impact on the participants’ essay writing skills. Also, employing Classroom Observation, the article attempted to qualitatively measure student engagement in the writing class. The findings further exuded that the EFL students observed were cognitively involved in the learning activities conducted in the class. Based on the foregoing findings, this study recommends that the process approach to (the teaching of) writing be adopted and used to teach writing in EFL classes across/in Niger.

ObjectivesChildren born preterm are at higher risk for special educational needs and poor academic attainment compared with term-born peers, yet education professionals receive limited training and have poor knowledge of preterm birth. We have developed an interactive e-learning resource and evaluated its efficacy in improving teachers’ knowledge of preterm birth and their confidence in supporting the learning of children born preterm.SettingEight primary, infant or junior schools in England.Participants61 teachers of children aged 4–11 years, of which 55 (90%) were female.InterventionInteractive e-learning resource designed to improve education professionals’ knowledge of long-term outcomes following preterm birth and strategies that can be used to support children’s learning (www.pretermbirth.info). In a repeated measures design, participants were given up to 30 days access to the e-learning resource, before and after which they completed the Preterm Birth Knowledge Scale (PB-KS; scores 0–33; higher scores indicate greater knowledge) to assess knowledge of outcomes of prematurity. Four Likert scale items were used to assess confidence in supporting children’s learning and 10 items were used to evaluate the utility of the resource. PB-KS scores and responses on confidence item were compared pre-resource and post-resource use.ResultsPB-KS scores significantly increased after accessing the e-learning resource (median (95% CI): pre-resource 13 (11 to 14); post-resource 29 (28 to 30)), equating to a 2.6 SD increase in PB-KS scores. Teachers’ confidence in supporting children born preterm was also significantly improved after using the resource. The utility of the resource was evaluated positively by participants with 97% reporting that they would recommend its use to others.ConclusionsThe e-learning resource substantially improved teachers’ knowledge of preterm birth and their confidence in supporting preterm children in the classroom. Use of this resource may represent a key advance in improving educational outcomes for children born preterm.

Context:Fatigue of the shoulder rotator muscles may negatively affect joint position sense (JPS) and ultimately lead to injury.Objective:Recovery of shoulder JPS after muscle fatigue.Design:A repeated-measures study.Setting:Musculoskeletal research laboratory.Patients:Thirteen subjects participated in joint position error tests and isokinetic concentric strength assessment in shoulder rotation, before and after rotator muscle fatigue.Interventions:Local muscle fatigue was induced using isokinetic concentric contractions of the shoulder rotator muscles.Main Outcome Measurements:Shoulder rotator strength and JPS error signals were measured before fatigue, immediately after fatigue, and every ten minutes thereafter for one hour.Results:Before shoulder rotation muscle fatigue, the accuracy of shoulder JPS was 2.79 ± 1.67 degrees. After muscle fatigue, the accuracy decreased to 6.39 ± 2.90 degrees. Shoulder JPS was influenced up to 40 minutes after muscle fatigue, but shoulder strength was only affected for 10 minutes after muscle fatigue.Conclusions:Proprioceptive recovery was slower than strength following fatigue of the shoulder rotators.

The purpose of the present experiment was to examine whether the use of selfhandicapping strategies influences participants’ anxiety levels before athletic performance. Seventy-one competitive basketball players participated in the study. A repeated measures design was used, such that state cognitive and somatic anxiety intensity and direction were measured before and after participants were given the opportunity to self-handicap. Overall, participants reported their cognitive anxiety to be more facilitating after they had the opportunity to self-handicap. Thus, participants who were given the opportunity to self-handicap (i.e., use claimed and behavioral self-handicaps), reported greater increases in perceptions of cognitive anxiety as facilitating their performance. This study shows the importance of looking at anxiety direction, and not just anxiety intensity, when examining self-handicapping’s effects on anxiety. Implications for sport psychologists are proposed.

Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo in adults and is a result of otolithic particles or debris that become free floating within a semicircular canal or adhere to the cupula. Characteristics of BPPV include brief episodes of latent onset vertigo that occur with changes in head position, transient rotary nystagmus beating toward the dependent ear, and reversed nystagmus upon sitting up. Both the vertigo and nystagmus fatigue quickly while maintaining the same head position. The BPPV may be classified as objective or subjective. Objective BPPV presents all the aforementioned symptoms whereas subjective BPPV presents all the symptoms without nystagmus. The accepted method of treatment for objective BPPV is canalith repositioning maneuvers (CRM); however, CRM are not traditionally used as the method of treatment for cases of subjective BPPV. Purpose: The purpose of the study was to determine if the subjective report of dizziness using the Dizziness Handicap Inventory (DHI) was different in patients with objective and subjective BPPV and to determine if the two groups showed similar improvements in perceived dizziness handicap following CRM treatment. Research Design: The present study utilized a retrospective, repeated measures design. Study Sample: Sixty-three adults with BPPV that were given the DHI both before and after CRM treatment. Data Collection and Analysis: Pre and post DHI results were analyzed for participants with objective versus subjective BPPV. A five-question DHI subscale was also analyzed between the groups. Results: A significant difference was noted between initial and posttreatment DHI scores for patients in both the subjective and objective groups when using the full-scale and subscale DHI. No significant difference was noted between groups for their initial or posttreatment DHI scores. The two groups also did not differ significantly in their initial or posttreatment DHI subscale scores. Conclusions: The results of the study indicated that individuals with both objective and subjective BPPV demonstrated significant improvement in DHI scores following CRM treatment. Additionally, there was no difference in DHI improvement for the subjective versus objective group suggesting CRM are effective for both subjective BPPV and objective BPPV. This improvement in DHI scores was also noted in the five-question DHI subscale with no significant difference noted between groups. These findings combined with previous studies suggest the presence or absence of nystagmus during Dix-Hallpike maneuvers is not related to the effectiveness of treatment using CRM.

Objective To determine by systematic review and metaanalysis if (1) bodily pain as measured by the 36-Item Short Form Health Survey (SF-36) is consistently increased in patient populations with chronic rhinosinusitis (CRS); and (2) if SF-36 bodily pain scores significantly and consistently improve following endoscopic sinus surgery (ESS). Methods Studies published in any language reporting SF-36 results before and after ESS were retrieved by searching MEDLINE, EMBASE, Web of Science, Cochrane databases, and additional Web-based sources (from 1980 to January 2008); by examining bibliographies of retrieved articles; and by contacting investigators in the field. Two authors independently evaluated studies for inclusion. Results After excluding 1 study reporting results as medians rather than as means, the remaining 10 observational ESS studies (909 patients) reported preoperative SF-36 bodily pain scores 0.95 SDs below the general population mean (more bodily pain) in average weighted by sample size. Using a repeated-measures design, all studies noted an improvement in SF-36 bodily pain domain scores following surgery, with a moderate-sized combined effect of 0.54 (95% confidence interval [CI], 040–0.69) and moderate heterogeneity (I2 = 50%). This pooled effect corresponds to a clinically and statistically significant mean improvement of 11.7 (95% CI, 7.1–16.3) units in the SF-36 bodily pain domain. Conclusions Bodily pain is consistently increased in patient populations with CRS. Using within-subject comparisons, a clinically and statistically significant improvement in bodily pain is noted after ESS, an improvement similar in size to that previously described for fatigue and other CRS symptoms.

Perceived thirst (TP) was evaluated as a dependent variable: can it distinguish among several levels of acute dehydration, is it reliable, and how does it respond to the ingestion of a fixed water volume post exercise? In a repeated-measures design, eight physically active students (24.5±3.6 years, mean±SD), reported to the laboratory on four non-consecutive days. They remained at rest or exercised at 32±3°C db and 65±6% rh to a randomly assigned dehydration equivalent to 1, 2, and 3% of body mass (BM). Following exercise, participants ingested a fixed water volume of 1.20% BM in 30 minutes; urine output, TP and plasma volume changes were assessed every 30 minutes over 3 hours. Post-exercise TP was not different before and after showering (p = 0.860), but it was significantly different among conditions (TP = 2.50 ± 0.45, 4.44 ± 0.72, 6.38 ± 0.82, and 8.63 ± 0.18 for 0, 1, 2, and 3% BM, p = 0.001). TP was associated with net fluid balance (rpart = -0.62, p < 0.0001) but, soon after drinking, TP was the same regardless of dehydration (p>0.05). Thirst perception is valid and reliable in the absence of drinking but it responds inappropriately to water intake.

AbstractAutism-Assistance Dogs (AADs) are highly-skilled service animals trained primarily to ensure the safety of an autistic child by preventing elopement and mitigating ‘meltdowns’. Although anecdotal accounts and case-studies have indicated that AADs confer benefits above and beyond safety, empirical support anchored in validated clinical, behavioral, and physiological measures is lacking. To address this gap, we studied children and their families before and after receiving a well-trained AAD using a within-subject, repeated-measures design. Notably, this study is the first to assess change in a biomarker for chronic stress in both autistic children and their parents. Final analyses included pre-/post-AAD data from 11 triads (parent/handler-dog-child) demonstrating significantly positive psychosocial and biobehavioral effects of AADs.

Background: Accurate measurement of oculomotor function using videonystagmography (VNG) is imperative for diagnosis and management of patients with reported dizziness. The oculomotor evaluation during VNG utilizes video-oculography providing valuable information regarding the central structures and pathways that control eye movements. Artifact may have an effect on the overall validity and reliability of VNG oculomotor tracings and can result from patient and/or recording errors. It is postulated that artifact could occur more frequently in the pediatric population due to both patient and equipment factors. Purpose: The purpose of this study was to systematically evaluate the occurrence and impact of artifact on saccades, smooth pursuit, and optokinetic (OPK) testing in normal pediatric and adult subjects using commercially available clinical VNG equipment and standard clinical protocols for oculomotor testing. Research Design: The present study utilized a retrospective analysis of a repeated measures design. Study Sample: Oculomotor results from a total of 62 participants were analyzed. Portions of these data have been presented in a previous research study. Group 1 consisted of twenty-nine 4- to 6-yr-olds with an average age of 4.86 (SD = 0.88) yr. Group 2 consisted of thirty-three 22- to 44-yr-olds with an average age of 25.2 (SD = 5.34) yr. Data Collection and Analysis: Raw oculomotor recordings were analyzed “offline” by a single masked, trained investigator. Each tracing was evaluated for instances of artifact including eye blinks, eye closure, eyes moving in opposite direction of the target, eye tracking software problems, and overall poor morphology. The number of instances of artifact were noted and recorded for each participant in both groups. Individual eye movements not affected by artifact were included for final analysis. Artifact rejection techniques were also compared. Results: The results indicated increased artifact for the pediatric group for saccade and smooth pursuit testing. Additionally, a significant decrease in instances of artifact was noted with an increase in age in months for both saccade and smooth pursuit findings. OPK results did not indicate any significant difference in instances of artifact between the pediatric and adult groups or any decrease in instances of artifact with increasing age in the pediatric group. Artifact rejection technique did not have a significant effect on oculomotor measures for either age group. Conclusions: Pediatric patients exhibit increased instances of artifact during VNG oculomotor testing, specifically during saccade and smooth pursuit testing, at least for the 4- to 6-yr-old population. A general age effect was also noted in this age group, with decreased artifact noted with increasing age. Artifact rejection technique was not a significant factor suggesting standard compared based strategies may be sufficient for use in the pediatric population. Additional study into the effect of artifact on oculomotor results for infants to age 3 yr and ages 7- to 18-yr-old, in the disordered population, and with additional equipment manufacturers is needed to confirm these results and further describe the impact of artifact on oculomotor findings in the pediatric population.
