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

Study Overview
=================
Brief Summary
-----------------
Measure the effect of a common used ankle manipulation on ligament length in the ankle.

Detailed Description
-----------------
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. The design of this study will allow to determine what the direct effect of a common a commonly used physical therapy ankle manipulation is on the length of the soft tissue connection between the smaller bone in the lower leg and the heel bone and the smaller bone in the leg and the ankle bone.
