    Jumping is a key skill in dance and the effect of different dance shoes on jump performance is not known. Female pre-professional and professional dancers (n=14) were recruited to perform consecutive maximum vertical jumps in second position in four types of jazz shoes and barefoot, with and without music. An overall effect of the jazz shoes was found both with and without music (

    THE RELATIONSHIP BETWEEN ANKLE LAXITY AND FRONTAL PLANE ANGLES DURING NETBALL SPECIFIC TASKS: A PILOT STUDY

    Ankle sprains are common in netball and, if quantified mechanical ankle laxity can be linked with ankle kinematics during common netball landing tasks, then preventative measures can be implemented to reduce the occurrence of such injuries. Four netball players had their ankle laxity measured with an ankle arthrometer and performed two landing tasks (a cutting manoeuvre and a linear running task involving a ball catch and sudden stop) within the 3D motion analysis laboratory. The participant with the highest arthrometry measured ankle laxity angle displayed the highest frontal plane range of motion during both landing tasks. A high correlation coefficient (R2=0.84) was found when comparing arthrometry measures with frontal plane range of motion during the cutting task. Although a promising relationship was observed, larger sample sizes are needed for more conclusive results

    Neural Excitability and Joint Laxity in Chronic Ankle Instability, Coper, and Control Groups

    Neuromuscular and mechanical deficiencies are commonly studied in participants with chronic ankle instability (CAI). Few investigators have attempted to comprehensively consider sensorimotor and mechanical differences among people with CAI, copers who did not present with prolonged dysfunctions after an initial ankle sprain, and a healthy control group
