The Effect of a Talocrural Thrust Manipulation on Lateral Ankle Ligament Integrity in a Subgroup of Healthy Individuals

Measure the effect of a common used ankle manipulation on ligament length in the ankle.

The purpose of this study is to determine what the effect of a common ankle manipulation on the supporting ligaments of the ankle.

Design: The researchers will conduct a quasi-experimental study with a method of convenience sampling.
