Effect of gender on trunk and pelvis control during lateral movements with perturbed landing     

Elmar Weltin  Albert Gollhofer  Guillaume Mornieux 《European Journal of Sport Science》2016,16(2):182-189

In lateral reactive movements, core stability may influence knee and hip joint kinematics and kinetics. Insufficient core stabilisation is discussed as a major risk factor for anterior cruciate ligament (ACL) injuries. Due to the higher probability of ACL injuries in women, this study concentrates on how gender influences trunk, pelvis and leg kinematics during lateral reactive jumps (LRJs). Perturbations were investigated in 12 men and 12 women performing LRJs under three different landing conditions: a movable landing platform was programmed to slide, resist or counteract upon landing. Potential group effects on three-dimensional trunk, pelvic, hip and knee kinematics were analysed for initial contact (IC) and the time of peak pelvic medial tilt (PPT). Regardless of landing conditions, the joint excursions in the entire lower limb joints were gender-specific. Women exhibited higher trunk left axial rotation at PPT (women: 4.0 ± 7.5°, men: ?3.1 ± 8.2°; p = 0.011) and higher hip external rotation at both IC and PPT (p < 0.01). But women demonstrated higher knee abduction compared to men. Men demonstrated more medial pelvic tilt at IC and especially PPT (men: –5.8 ± 4.9°, women: 0.3 ± 6.3°; p = 0.015). Strategies for maintaining trunk, pelvis and lower limb alignment during lateral reactive movements were gender-specific; the trunk and hip rotations displayed by the women were associated with the higher knee abduction amplitudes and therefore might reflect a movement strategy which is associated with higher injury risk. However, training interventions are needed to fully understand how gender-specific core stability strategies are related to performance and knee injury.  相似文献

创伤性近侧指间关节屈曲挛缩治疗方法的探讨     

苏峰  张春林  张军威  李国通 《河北北方学院学报(医学版)》2001,(1)

目的:对创伤性近侧指间关节挛缩的发病机制和治疗方法进行探讨。方法:对1995～2000年在我院治疗的创伤性近侧指间关节屈曲挛缩病例进行回顾,指间关节挛缩的发病机制,根据关节内外粘连的不同因素进行松解手术治疗。结果:创伤性近侧指间关节屈曲挛缩的病变可分为关节内粘连、关节外粘连及复合性粘连。经过:(1)单纯松解掌板延长及屈指浅肌腱切断等手术。(2)手术加牵引术,取得了良好结果。平均改善关节活动度达100度(屈)(伸)-10度。结论:(1)创伤性近侧指间关节屈曲挛缩的发生与早期处理不当有关。(2)粘连可以是关节内或关节外因素及复合因素造成。(2)手术治疗配合术后牵引治疗可取得良好的效果。  相似文献   

Collaborative research for sustainable learning: the case of developing innovation capabilities at Volvo Cars   总被引：1，自引：1，他引：0  

Sofia Börjesson 《Action Learning: Research and Practice》2011,8(3):187-209

This paper aims to make a contribution to the stream of literature on action research by describing a longitudinal collaborative research project which evolved out of a long-term, participation partnership with Volvo Cars. The collaboration was aimed at developing innovation capabilities in the company and accumulating knowledge on how capabilities are developed. The paper provides insights into the design of collaborative research projects to enable mutual, sustainable learning. It draws on key notions in the literature on collaborative management research and action learning, highlighting the research design of the project at Volvo Cars and its relations to action learning. The paper describes how the research design opened the way to establishing a learning system at Volvo Cars while simultaneously generating new scientific knowledge within the area of innovation capabilities. The paper provides rich and detailed data on a collaborative research setting and highlights key aspects related to organizing and undertaking collaborative research.  相似文献

依据技术的特性和技术出资的特殊性,指出我国与其相关的法规存在某些缺憾。提出在中外合资经营的企业中,要有对技术出资限围的限定法规条款;并且要用已有的法规对技术出资进行监管;也要注意对第三方即合资企业之债权人的利益保护。  相似文献   

股份有限公司董事对第三人的损害赔偿责任     

胡必坚  吴双全 《安顺学院学报》2007,(1)

董事因故意或者重大过失对第三人的损害赔偿责任,我国《公司法》对此缺乏一般性规定,这对于未上市的股份公司的第三人利益保护是非常不利的。分析我国股份公司董事对第三人赔偿责任立法现状及其不足,认为应当通过公司法做出诸如股份公司董事对包括债权人在内的第三人损害赔偿责任的原则性规定、区分不同种类董事的赔偿责任以及改进董事责任保险制度、完善股东诉讼机制和导入债权人派生诉讼制度等措施来适度强化董事民事责任,保护第三人利益,实现公司相关者利益的合理平衡,最终促进经济发展。  相似文献
