Introduction: Ankle joint injuries are one of the most common injuries in the body during physical activity and damage to the ankle-sensory-muscle control system is known as the main cause of repeated ankle instability.The decrease in proprioceptive and awareness sense of movement, the agent an important part in reducing balance and as a result of recurrence is the fact that the athlete often leads to exercise.The ankle joints have essential role in balance and postural control. Balance control and postural maintenance contribute to the consistent coordination of sensory messages it depends on the vestibular system, vision and sensory information.The aim of this study was to evaluate the effect of balance training on the postural control stability of athletes with chronic ankle instability by manipulating proprioceptive, visual and auditory information.
Methodology: In this semi-experimental study,30 soccer players with chronic ankle instability were randomly divided into two groups of exercise (n=15) and control (n=15), which were divided into two groups of measurements: pre- and post-test.The test was carried out and the experimental group training program was six weeks of balance training against disturbances.To evaluate the postural control stability of the subjects, the sensory organizing test of the Computerized dynamic Posturography system was used.This device has a sustained rate of 6 states: first(there are 3 senses of sight, hearing and proprioceptive), second(vision outage), third(auditory manipulation), fourth(proprioceptive manipulation), fifth(removal of vision and proprioceptive manipulation)and sixth(Adjustment of auditory sense and proprioceptive).The findings were analyzed using Co-variance analysis.The statistical analysis was performed by SPSS software version 22 at a significant level of α≤0.5.
Results: The results showed that the mean stability score in the experimental group and control group in the first condition, with all three senses of sight, proprioceptive and hearing is more than other condition,and the score of sustainability in the sixth position, which has a hearing and proprioceptive sensation, is less than other conditions.The average score of postural control stability in the experimental group after six weeks of training in each of the six conditions is higher than that of the control group.
Discussion: Six weeks of balance training significantly increased postural control stability,because improved the proprioceptive and the transmission of information and possibly the improvement in the integrity of proprioceptive,entrapment,vision,and increased muscle spindle sensitivity,altering the motor control pattern and speeding up the time of sending sensory information and starting muscle activity.It results in more stability in postural control and stability.
