Background and Aims: The accurate mechanisms of ankle instability cannot be assessed in the absence of reliable knowledge about ground reaction force (GRF) variables. The purpose of this study was to evaluate the test-retest reliability of GRF variables during forward and lateral jump-landing in volleyball players with functional ankle instability (FAI). Methods: Eighteen professional volle...

Lateral ankle inversion sprains occur frequently in sports that mostly concern young, physically active individuals. It constitutes between 15%-75% of all sports-related injuries, and mainly occurs in high-risk sports like team handball, basketball, soccer, or volleyball. Although the majority of patients recover completely after their first acute injury, disabling symptoms of pain and swelling...

[Purpose] To report the effects of ankle balance taping for a patient with chronic ankle instability (CAI). [Subject] A 33-year-old man with a 10 year history of chronic ankle stability. [Methods] ABT with kinesiology tape was performed for 2 months (average, 16 h/day) around the right ankle. [Results] At the end of two months, no ankle instability was noted when ascending and descending the st...

BACKGROUND Chronic ankle instability (CAI) is a disabling condition often encountered after ankle injury. Three main components of CAI exist; perceived instability; mechanical instability (increased ankle ligament laxity); and recurrent sprain. Literature evaluating CAI has been heavily focused on adults, with little attention to CAI in children. Hence, the objective of this study was to system...

This study critically reviews the effectiveness of exercise therapy and manual mobilisation in acute ankle sprains and functional instability by conducting a systematic review of randomised controlled trials. Trials were searched electronically and manually from 1966 to March 2005. Randomised controlled trials that evaluated exercise therapy or manual mobilisation of the ankle joint with at lea...

BACKGROUND Chronic ankle instability has been associated with altered joint kinematics at the ankle, knee and hip. However, no studies have investigated possible kinematic deviations at more distal segments of the foot. The purpose of this study was to evaluate if subjects with ankle instability and copers show altered foot and ankle kinematics and altered kinetics during a landing task when co...

Altered gait kinematics in individuals with functional ankle instability (FAI) are thought to contribute to instability; however, research fi ndings are inconsistent. Findings may be clarifi ed with the use of a multisegment foot model and a coper group. Participants included 69 individuals: 23 with FAI, 23 controls, and 23 copers (individuals with a history of ankle sprain but no instability)....

CONTEXT Although lateral ankle sprains are common in athletes and can lead to chronic ankle instability (CAI), strength-training rehabilitation protocols may improve the deficits often associated with CAI. OBJECTIVE To determine whether strength-training protocols affect strength, dynamic balance, functional performance, and perceived instability in individuals with CAI. DESIGN Randomized c...
