BackgroundStochastic resonance stimulation (SRS) transmits subsensory electrical Gaussian white noise into the body to enhance sensorimotor function. This therapy has improved static single leg balance in subjects with functional ankle instability. However, the effect of this stimulation on dynamic single leg balance is not known. Improvements in dynamic single leg balance with SRS may have implications for enhancing functional rehabilitation for ankle instability. Thus, the purpose of this study was to determine the effects of SRS on dynamic single leg balance in subjects with functional ankle instability.MethodsThis study was an experimental research design and data were collected in a sports medicine research laboratory. Twelve subjects with functional ankle instability (69 ± 15 kg; 173 ± 10 cm; 21 ± 2 years) reported a history of ankle sprains and instability at the ankle with physical activity. A single leg jump-landing test was used to assess dynamic balance. Subjects were required to jump between 50% and 55% of the maximal vertical jump height, land on a single leg atop a force plate, and stabilize as quickly as possible. Jump-landing tests were performed with and without SRS. Three trials were performed for each treatment condition (SRS and control). A randomized block design was used to determine test order. Anterior/posterior and medial/lateral time-to-stabilization were computed to assess dynamic balance. Lesser time indicated better stability. One-tailed paired samples t tests were used for analysis (α ≤ 0.05).ResultsSRS improved anterior/posterior time-to-stabilization (stochastic resonance = 1.32 ± 0.31 s, control = 1.74 ± 0.80 s, p = 0.03), but did not enhance medial/lateral time-to-stabilization (stochastic resonance = 1.95 ± 0.40 s, control = 1.92 ± 0.48 s, p = 0.07).ConclusionClinicians might use SRS to facilitate balance improvements with sagittal plane dynamic single leg balance exercises that patients may not be able to perform otherwise.  相似文献

The Survey of Income and Program Participation (SIPP) is one of a few national surveys that regularly collects data identifying the American population of persons with hearing loss or deafness. Estimates from the SIPP indicate that fewer than 1 in 20 Americans are currently deaf or hard of hearing. In round numbers, nearly 10,000,000 persons are hard of hearing and close to 1,000,000 are functionally deaf. More than half of all persons with hearing loss or deafness are 65 years or older and less than 4% are under 18 years of age. However, these findings are limited to those who report difficulty hearing "normal conversation" and do not include the larger population of persons with hearing loss for which only hearing outside the range and circumstances of normal conversation is affected. Policy makers, communications technology manufacturers, health and education service providers, researchers, and advocacy organizations have an interest in these results.  相似文献

OBJECTIVE: The current study examined the prevalence and characteristics of childhood sexual abuse in a jailed-based population. METHODOLOGY: A retrospective, self-reported survey was administered over an 8-week period to a random sample of 100 men who were incarcerated in a county jail in Southeastern Texas. The survey included questions about childhood sexual experiences before and after puberty, drug history and use, and sexual risk-taking behaviors. RESULTS: Of the 100 male inmates who participated in this study, 59% reported experiencing some form of sexual abuse before puberty, and all such instances occurred before or at the age of 13 years. The first episode of childhood sexual abuse began at an average age of 9.6 years (SD = 2.4), and ended at an average age of 13.0 years (SD = 2.3). Kissing and touching without intercourse (64%) was the common pattern of sexual abuse experience reported. The total number of perpetrators was 165, with 10% male and 90% female. Friends (n = 72) and family (n = 56) were the most frequent perpetrators. CONCLUSION: Childhood sexual abuse may be more prevalent among inmates than among males in the general population. These results show a high percentage of inmates who report a history of childhood sexual abuse; this rate is higher than those reported by other studies for incarcerated males. The findings support the belief held by professionals in the criminal justice field that a significant number of incarcerated males may have been victims of sexual abuse.  相似文献

Abstract Digital environments are one of the newest methods of resource‐ and program‐creation to be added to the museum toolkit, and are increasingly employed by museums across all fields to support learning. Unfortunately, this category is also one of the least‐fleshed‐out components in the Learning Science in Informal Environments (LSIE) chapter devoted to media. The report does not take into account the increasingly interwoven nature of media resources, particularly those found in digital environments. It is imperative that museums both become familiar with the breadth of research that is available related to digital environments and that they continue to specifically build an understanding of how this works in a museum setting.  相似文献

In secondary schools, subjects dominate teaching and also the organizational structures. Typically, subject department heads perform a middle-management role in secondary schools and often this role is taken-for-granted and unquestioned. In this article, we examine the impact on secondary school culture and the resulting changes to practice when the department middle-management structure and roles are open to revision. We investigate the experiences of two schools that are part of a longitudinal study on reculturing and restructuring in all secondary schools in one school district in Ontario, Canada. Our research indicates that structural change initiated by school level participants is a prerequisite to real change and that structural changes preceded cultural changes. However, it is the process of creating the new structures that is the key consideration as mandating an alternative might not be facilitative of cultural change. The primary research question guiding this article is: what impact does involvement in restructuring a middle-management organizational model have on the culture of a school and the change process experienced by staff members?  相似文献

To succeed academically, college students must actively construct course information, synthesize this information with information from texts and other resources, understand this information so that they can succeed on various forms of assessments and ultimately retain this information for the long term. While the complexity of these demands has been modeled somewhat metaphorically, there has been little ecologically valid research into learning in authentic classroom contexts. The present study examines the interrelationships among student perceptions of the learning context, test complexity, study strategies, and academic performance. Results of a path analysis demonstrated that perceptions of the teaching format and test complexity were positively related to the study strategies reported, and these study strategies were further related to the reported course performance.  相似文献

In 1996, The Ministry of Education of the Province of Quebec authorized a plan to support the integration of new information technologies and communications (NTIC) in its schools. An expenditure of $318 million dollars was announced for the purchase and upgrade of hardware and software. In response to this initiative, The Concordia University Centre for the Study of Learning and Performance (CSLP) approached the Quebec schoolboards, proposing partnerships between them and the Centre to facilitate the integration of these technologies into pedagogical practices. This article describes a needs assessment performed by the university in two Quebec elementary schools. The collected data revealed that teachers are currently using computers primarily for word processing and to prepare report cards. While they are somewhat dissatisfied with previous professional development, they are still highly interested in receiving training on how to better incorporate technology into their pedagogical practices. General recommendations and a workshop are outlined.  相似文献
