Knee injuries in golf comprise approximately 8% of all injuries, and are considered to result from overuse, technical faults or a combination of those factors. This review examines factors involved in injury, including the structure of the knee joint, kinematics and kinetics of the golf swing, forces sustained by knee joint structures and the potential for joint injury as well as injury prevention strategies. The golf swing generates forces and torques which tend to cause internal or external rotation of the tibia on the femur, and these are resisted by the knee ligaments and menisci. Research has shown that both maximum muscle forces and the forces sustained during a golf swing are less than that required to cause damage to the ligaments. However, the complex motion of the golf swing, involving both substantial forces and ranges of rotational movement, demands good technique if the player is to avoid injuring their knee joint. Most knee injury in golf is likely related to joint laxity, previous injuries or arthritis, and such damage may be exacerbated by problems in technique or overuse. In addition to appropriate coaching, strategies to remedy discomfort include specific exercise programmes, external bracing, orthotics and equipment choices. 相似文献

'Dissertations into Practice' is a new regular feature in the Health Information and Libraries Journal, which aims to encourage students to write for publication. The idea is that students will write an extended abstract of their health-related dissertations, outlining the methods used and commenting on the implications for practice. Co-written with their dissertation or workplace supervisor, this feature will provide a safe environment for students to see their writing in print, possibly for the first time, while ensuring that invaluable research reaches a wider audience than might otherwise be the case. 相似文献

The study reported was part of a large thinking skills intervention for 11–12-year-old children. This paper focuses on the impact of a thinking skills intervention on children's understandings of intelligence. A total of 178 children (n = 86 girls and n = 92 boys) across six schools participated in the study. Children were individually pre-tested in the classroom using written tasks designed to tap concepts of intelligence (definitions, characteristics, causes of intelligence, and the stability of intelligence: entity versus incremental concepts) and a variety of thinking skills. Schools were allocated into one of three intervention conditions: control condition; individual condition; collaborative learning condition. Children in the individual and collaborative learning conditions participated in an 8-week thinking skills intervention. Children in the individual condition worked individually on tasks to apply the thinking skills whereas learners in the collaborative condition applied the thinking skills on tasks in groups of four. Following the thinking skills intervention all children were individually post-tested using the pre-test measures. The results showed that the intervention had an impact on children's understanding of intelligence. In particular, the collaborative learning intervention led to most improvement in concepts of intelligence. The results are discussed with reference to theories of intelligence concepts and thinking skills interventions. 相似文献
