Assessment of Intrinsic Risk Factors for Ankle Injuries in Ballet Dancers

Overview

This study aims to evaluate intrinsic risk factors (muscle strength, joint range of motion, static and dynamic balance) that may lead to ankle injuries in ballet dancers and to examine the relationship between these factors and ankle injuries experienced in the last 12 months. By comparing ballet dancers who have suffered injuries requiring physical therapy or forcing them to take a break from dancing for more than one week in the past year with uninjured ballet dancers and a control group, the findings aim to contribute scientifically to the development of individualized rehabilitation programs and the safe and effective planning of return-to-stage processes. Furthermore, it is believed that these data may support the reduction of time and financial losses among dancers.

This study aims to evaluate intrinsic risk factors that may lead to ankle injuries in ballet dancers. Ankle injury risk factors are divided into two categories: intrinsic and extrinsic. Extrinsic risk factors are external to the individual, such as surface type, shoe wear, and type of athletic activity (training and competition) that may affect the athlete's performance. Intrinsic risk factors include age, gender, strength, joint range of motion, balance, and motor control, which affect the athlete's ability to perform sports-related activities. The study will be conducted with a total of 45 participants, including 30 participants aged 18 and over who reside in Izmir and are professional ballet dancers, and 15 control participants who have no previous dance experience. Of the 30 professional ballet dancers, 15 will be selected from dancers who have suffered an ankle injury requiring physical therapy or forcing them to take at least a one-week break from the stage within the last year. The other 15 ballet dancers will be those who have not experienced any problems due to an ankle injury within the last year. Participants will be asked whether they have suffered an injury requiring medical attention in the ankle region within the last 12 months; the data obtained will be correlated with various biomechanical measurements. Each participant will perform a standard warm-up program before the tests. The four main parameters to be evaluated in the study are as follows: * Ankle muscle strength (4 directions in concentric and eccentric modes) * Joint range of motion (ROM) * Static balance * Dynamic balance Strength measurements will be assessed using an isokinetic dynamometer (Isomed 2000), joint range of motion using a goniometer, dynamic balance using the Y Balance Test (YBT), and static balance using the Diers Formetric 4D pedobarographic balance system. Strength measurements will be performed at angular velocities of 30°/s and 120°/s for plantar flexion and dorsiflexion and 60°/s and 90°/s for inversion and eversion in both the dancer and control groups. The primary objective of the study is to determine the relationship between a history of ankle injury and these intrinsic parameters. It also aims to compare the control group with ballet dancers who have not suffered an ankle injury in the last year in terms of these intrinsic parameters.
