Structural characteristics and functional consequences of lateral ankle sprains
type: CreativeWork
description: Ankles injuries account for 8% of health care consultations and ankle sprainsconstitute about 85% of all ankle injuries. Lateral ankle sprain is a type of injury that affectsboth the general and the sporting population. Lateral ankle sprain has a high rate ofrecurrence which can often lead to individual developing chronic ankle instability. Thischronicity contributes to continue deficits of sensorimotor and constrained functioning)which could have a decrease effect on the health-related quality of life, the level of physicalactivity, and absence from training or competition for athletes, thus create a substantial globalhealthcare burden. With such negative consequences and related financial burden associatedwith LAS and CAI enhanced effort to understand structure and function differences betweenthose that develop CAI and those that do not following an initial acute LAS is needed. Understanding the relationships between the integrity of the ankle structures pre andpost sprain, and functional ability of the ankle is important to inform our understanding of thelong-term effects of sprains and consider better targeting of interventions. This thesis aims tostudy the structural characterisation and functional consequences of lateral ankle sprain.Three studies were undertaken. The first study used ultrasound to characterise and compare selected ankle structuresbetween healthy (n=48), coper (n=22) and chronic ankle instability (n=32) groups.Participants with prior injury had significantly longer anterior talofibular ligament when theligament was under tension (by 6% when compared CAI to healthy participants), and thickeranterior talofibular ligament and calcaneofibular ligament compared to healthy participants(by 54.21% and 8.3% respectively when compared CAI to healthy participants). These grossstructural differences are evidence of residual structural damage. However, they do notindicate whether the quality and nature of the ligament tissue is similarly affected. In study…
