The aim of this study was to assess changes in body morphology, anatomical alignment and prevalence of patellofemoral pain (PFP) in young female dancers along one year of pubertal growth, and to identify the risk factors related to PFP in these young dancers. Both legs of 60 dancers were evaluated during grade 7 and again after 1-year. At each of these points in time, the dancers were interviewed concerning their background, and anthropometric measurements, lower-limb physical examinations and knee ultrasound scans were performed. Morphological parameters changed significantly from baseline to follow-up. PFP was found in 53.3% of the dancers’ knees at baseline. At follow-up, 55.4% of the asymptomatic knees at baseline developed PFP, and only 9.4% of the symptomatic knees at baseline recovered. Lower BMI was identified among dancers who developed PFP during follow-up compared with dancers with no PFP, either at baseline or at follow-up. A positive grinding and positive Patellar Inhibition Test (PIT) were found to be risk factors for PFP at follow-up. A high prevalence of young dancers suffered PFP, from injuries they sustained mostly during the 1-year of dance practice. Parameters predisposing the dancers to PFP should be identified at early stages of dance class. 相似文献

This paper focuses on the effects of social–structural factors (age, ethnicity and gender) on university students’ use of web‐based instruction. The study uses data from registration questionnaires of students at the Open University of Israel. During the period between 1995 and 2002 there has been a continuous increase in the proportion of students who use the Internet and email for study purposes. However, a significant minority (one‐third of the students) are still not Internet users. Previous studies have referred to the digital divide in terms of differences in access to the relevant hardware and explained it mainly by social and structural factors. Current research tends to focus on the digital divide in terms of use rather than access, and explains it mainly by micro, individual and situational characteristics. The present study shows that structural factors such as age, gender and ethnicity also play a significant role in the continuous existence of the usage gap. The social and educational implications of this gap are discussed. 相似文献

An immigrant has to adjust to a new environment, — physically, mentally and socially. Counseling methods, when applied to immigrants, should be geared to the special conditions and needs of this group. This paper describes the experiences gathered from vocational counseling of 5000 young high-school graduates who immigrated to Israel from many countries. On the basis of these experiences specific counseling tools, techniques and processes have been developed. 相似文献

ABSTRACTAiming to evaluate the prevalence of unilateral/bilateral patellofemoral pain (PFP) among young dancers, and to investigate whether different factors are associated with PFP in young dancers, 132 dancers aged 12–14 years were assessed for PFP. Anthropometric parameters, proprioception ability, dynamic postural balance (DPB), and muscle strength were measured. PFP was found in 64.1% of the dancers. No significant differences in the prevalence of dancers with no, unilateral, or bilateral PFP at different ages were found. Significant age effects were found for anthropometric and developmental measurements, and for intensity of training. PFP effect was found for DPB asymmetry, ankle proprioception, and leg-length %height. A higher hip abductor/adductor ratio was associated with PFP in 14-year-old dancers. Binomial logistic regression showed that increased number of hours per day (h/day) and decreased number of hours per week (h/week), low proprioception scores, greater leg length as %height, and more anterior DPB asymmetry were significant predictors of PFP. In conclusion: unilateral/bilateral PFP is common among young dancers. Body morphology, reduced ankle proprioception ability, DPB asymmetry, and increased h/day of practice are associated with PFP. Dance teachers should start monitoring the impact of training and implement injury modification/prevention strategies when their students are at a young age. 相似文献

In the present study, we tried to determine the association between joint ranges of motion, anatomical anomalies, body structure, dance discipline, and injuries in young female recreational dancers. A group of 1336 non-professional female dancers (age 8-16 years), were screened. The risk factors considered for injuries were: range of motion, body structure, anatomical anomalies, dance technique, and dance discipline. Sixty-one different types of injuries and symptoms were identified and later classified into four major categories: knee injuries, foot or ankle tendinopathy, back injuries, and non-categorized injuries. We found that 569 (42.6%) out of the 1336 screened dancers, were injured.The following factors were found to be associated with injuries (P < 0.05): (a) range of motion (e.g. dancers with hyper hip abduction are more prone to foot or ankle tendinopathies than dancers with hypo range of motion; (b) anatomical anomalies (scoliotic dancers manifested a higher rate of injuries than non-scoliotic dancers); (c) dance technique (dancers with incorrect technique of rolling-in were found to have more injuries than dancers with correct technique); (d) dance discipline (an association between time of practice en pointe and injury was observed); and (e) early age of onset of menarche decreased risk for an injury. No association between body structure and injury was found. Injuries among recreational dancers should not be overlooked, and therefore precautionary steps should be taken to reduce the risk of injury, such as screening for joint range of motion and anatomical anomalies. Certain dance positions (e.g. en pointe) should be practised only when the dancer has already acquired certain physical skills, and these practices should be time controlled. 相似文献

The current study gives voice to a group of remarkable returning college students whose lives are defined by multidimensional marginality. These students are single mothers who grew up in traditional families in the outer periphery of Northern Israel, where they still lived at the time of this study. Drawing on the women’s life stories gathered from in-depth interviews, the purpose of the study was twofold: to examine their multidimensional marginality in the context of the complexity of social situations they are required to face and to understand the impact of higher education upon that marginality and upon their lives. The findings demonstrate, quite powerfully, the impact of the participants’ student status on their discourse with their previously excluding family of origin, and the significance of their status for their personal growth process and for their relationship with their children. The process of matriculating into a higher education degree programme, and their continued progress in the programme, enabled these women to become proactive in moving from the margins towards a more central position of affecting and becoming a role model for their children, their families of origin and their communities. 相似文献
