This group will only take part in the data collection sessions. After the first testing session (Pre-Intervention) the participants will be asked to rest comfortably for 5 minutes. After the rest period, they will be reassessed. Upon completion of the second testing, they will be asked to maintain the same lifestyle over the course of 2 weeks. They will then be asked to return to the lab after the 2 week interval to be tested again. Upon completion of the third testing session, they will be contacted after 1 month to complete the self-reported function questionnaires.

The posterior ankle mobilization treatment is a manual therapy technique that consists of gently gliding your ankle in the backward direction through a pain free range of motion. This is a common therapy technique used by athletic trainers for the treatment of ankle sprains. The objective of this therapy technique is to glide the ankle into the area which restricts range of motion and gently stretch the restricted area. To begin this treatment, a certified athletic trainer with experience in applying this therapy technique will provide mild traction to the ankle joint to lightly distract the bones of the ankle joint. The athletic trainer will then apply two sets of joint mobilizations which will each last 2 minutes. Each repetition will consist of gently gliding the ankle joint in the backward direction until an area of restriction is reached. The athletic trainer will push into the restriction and then glide the ankle back to the starting position.

The foot massage treatment is a manual therapy technique that consists of gently rubbing the bottom of your feet with both hands like kneading dough.

It has two sections which will be used to assess disability associated with activities of daily living and sport activities.

Gait initiation is a laboratory technique that involves the use of a force plate. Participants are asked to stand on the force plate with feet and step off the force plate with either the right or left foot. The size of the weight shifts a participant makes while taking a step are evaluated using the force plate. Each participant will complete 5 trials stepping with each leg for every time point.

Time to Boundary is a balance measurement in which a person maintains single leg stance on a force plate for 10 seconds. This measurement technique evaluates the amount of time a person has to make corrections to maintain balance. Each participant will perform 12 trials for each time point. Each leg will be tested 6 times, 3 with eyes open and 3 with eyes closed.

The Weight-bearing Lunge Test is a measure of ankle dorsiflexion range of motion while the participant stands in front of a wall.
