On the other hand, damage to this joint is an important factor in affecting balance and consequently re-injury. Strengthening the factors that help maintain balance and posture, can be a basic strategy in the treatment of balance and postural problems, as well as injuries.</span></span><br> <span style="unicode-bidi:embed"><span style="color:black"><b><span style="color:#990099">Methods: </span></b>In this quasi-experimental study, 30 patients with chronic ankle instability were randomly divided into experimental and control groups. Both groups were pre-tested and the experimental group performed core stability exercises against gravity for six weeks. Post-test was taken again from both groups. Data were analyzed using one-way analysis of covariance.
