Although patellar taping has been shown to reduce pain in participants with patellofemoral pain syndrome, the mechanisms of pain reduction have not completely been established following its application. The purpose of this study was to evaluate EMG activity of vastus medialis and vastus lateralis following the application of patellar taping during a functional single leg squat. Both vastus medialis obliquus-vastus lateralis onset and vastus medialis obliquus/vastus lateralis amplitude of 18 participants with patellofemoral pain syndrome and 18 healthy participants as controls were measured using an EMG unit. This procedure was performed on the affected knee of participants with patellofemoral pain syndrome, before, during, and after patellar taping during unilateral squatting. The same procedure was also performed on the unaffected knees of both groups. The mean values of vastus medialis obliquus-vastus lateralis onset prior to taping (2.54 ms, s = 4.35) were decreased significantly following an immediate application of tape (-3.22 ms, s = 3.45) and after a prolonged period of taping (-6.00 ms, s = 3.40 s) (P < 0.05). There was also a significant difference between the mean values of vastus medialis obliquus-vastus lateralis onset among controls (-2.03 ms, s = 6.04) and participants with patellofemoral pain syndrome prior to taping (P < 0.05). However, there were no significant difference between the ranked values of vastus medialis obliquus/vastus lateralis amplitude of the affected and unaffected knees of participants with patellofemoral pain syndrome and controls during different conditions of taping (P > 0.05). Decreased values of vastus medialis obliquus-vastus lateralis onset may contribute to patellar realignment and explain the mechanism of pain reduction following patellar taping in participants with patellofemoral pain syndrome. 相似文献

Guided by social cognitive theory (SCT), we investigated whether exercise self-regulatory efficacy beliefs can be activated nonconsciously in individuals experienced and inexperienced in exercise self-regulation, and whether these beliefs are automatically associated with exercise self-regulation processes. The study used a 2 (Exercise Self-Regulation Experience Group) × 3 (Prime Condition) between-subjects design in which individuals experienced and inexperienced in exercise self-regulation were randomly assigned to receive subliminal, supraliminal, or no priming of exercise self-regulatory efficacy beliefs. Participants completed hypothetical diary entries, which were assessed for exercise self-regulatory efficacy and self-regulation expressions using content analyses with a SCT coding system and the Linguistic Inquiry and Word Count (LIWC) text analysis program. For both exercise self-regulation experience groups, self-efficacy priming led to more expressions of low exercise self-regulatory efficacy and dysfunctional exercise self-regulation strategies compared with the control prime. For participants experienced in exercise self-regulation, supraliminal priming (vs. control priming) led to more expressions of high exercise self-regulatory efficacy and functional exercise self-regulation strategies. For the experienced groups, priming led to automaticity of exercise expressions compared with the control condition. For inexperienced participants in the subliminal prime condition, priming led to automaticity of self-regulatory efficacy beliefs and work-related goals compared with the control condition. Automatic activation of exercise self-regulatory efficacy and exercise self-regulation processes suggests that self-regulation of exercise behavior can occur nonconsciously. 相似文献

This paper presents a study which has evaluated the extent to which a sample of elementary special education teachers in Kuwait understand and make use of evidence-informed approaches in the mainstream classroom with children with special educational needs. A questionnaire survey was developed and administered (N = 150), focussing on teacher understanding of and use of two selected evidence-informed approaches: peer tutoring strategy and the JIGSAW strategy. Results revealed a good degree of understand and use of both strategies. Recommendations are made in relation to further research on the evidence-informed practice for the effective inclusion of children with special educational needs in Kuwait and internationally. 相似文献

The growing complexity of scientific challenges demands increasingly intense research collaboration, both domestic and international. The resulting trend affects not only the modes of producing new knowledge, but also the way it is disseminated within scientific communities. This paper analyses the relationship between the “degree of internationalization” of a country’s scientific production and that of the relevant citing publications. The empirical analysis is based on 2010-2012 Italian publications. Findings show: i) the probability of being cited increases with the degree of internationalization of the research team; ii) totally domestic research teams tend to cite to a greater extent totally domestic publications; iii) vice versa, publications resulting from international collaborations tend to be more cited by totally foreign publications rather than by publications including domestic authors. These results emerge both at overall and at discipline level. Findings might inform research policies geared towards internationalization. 相似文献

The current study used a pretest–posttest randomized control group design with 73 Head Start students, ages 3–5 years. The researcher served as the interactive writing teacher for the treatment group, rotating to five different classrooms in one Head Start center 3–4 days a week for 13 weeks. Children in the treatment group received a 10–15 min interactive writing lesson each day in small groups within their own classroom settings. Children in the control group received standard literacy instruction in small groups with their own classroom teachers. Child outcome data on upper case, lower case, and letter sound identification were collected before and after the intervention for both groups. Based on the large frequency of zeros on outcomes, zero-inflated Poisson regression analyses were performed. The results of the study showed that children receiving interactive writing identified more lower case and upper case letters at the end of the study relative to children in the control, but no differences were observed on letter sounds. While continued evaluation of the interactive writing strategy is needed in the preschool setting, the evidence from the current study shows encouraging trends in alphabet knowledge skill development as a result of this strategy. 相似文献

The connection between human cognitive development and motor functioning has been systematically examined in many typical and atypical populations; however, only a few studies focus on people with Down syndrome (DS). Twelve adolescents with DS participated and their cognitive control, measured by the Corsi-Block tapping test (e.g., visual working memory), the Auditory Memory span test (e.g., verbal working memory) and the Tower of London test (e.g., cognitive planning), and motor control, measured by the Purdue Pegboard (e.g., fine motor control), were measured in this study. Results indicate that if people with DS have better performance in fine manual dexterity, they will have better performance in cognitive planning and verbal working memory abilities. The co-activation hypothesis of the prefrontal area and the cerebellum may support this positive relationship. Hence, it is suggested people with DS will obtain benefits in cognitive control by participating in further motor intervention. 相似文献

There has been growing interest in the mental health benefits of self‐compassion. This study was designed to establish norms on the Self‐Compassion Scale–Short Form, a popular measure of self‐compassion for individuals seeking counseling, and to examine group differences in self‐compassion based on gender, race/ethnicity, sexual orientation, previous counseling, and psychiatric medication use. Data for this study were collected through the Center for Collegiate Mental Health, a practice‐research network of more than 240 college and university counseling centers. 相似文献
