Summary

The purpose of this study is to determine changes in the brain associated with improvement in ankle range of motion following ankle manual therapy procedures in individuals with post-acute ankle sprains

Conditions

  • Ankle Sprain

Interventions

OTHER

High velocity, low amplitude stretch

This group (n=9) will receive talocrural traction manipulation. With the subject in a seated position on a treatment table and the lower extremity of interest stabilized to the table with a belt, a single standardized treating investigator will grasp the foot of interested with the thenar eminences on the foot's plantar surface. A thrust will be delivered parallel to the long axis of the subject's lower leg after the treating therapist induces passive ankle dorsiflexion to end range.

OTHER

Slow, mobilization stretch

This group (n=9) will receive talocrural traction mobilization. With the subject in a seated position on a treatment table and the lower extremity of interest stabilized to the table with a belt, a single standardized treating investigator will grasp the foot of interested with the thenar eminences on the foot's plantar surface. Traction will be delivered to the talocrural joint at the treating investigator's second perception of tissue resistance in 3 bouts of 30-second holds, separated by 10 seconds of rest.

OTHER

Passive Positioning

This group (n=9) will receive the manual therapy control intervention. This will consist of the same patient and clinician preparation for the mobilization/manipulation techniques. However, a single standardized treating investigator will simply maintain passive ankle positioning for the duration of 1 deep inhalation and exhalation by the subject rather than induce an iatrogenic force characteristic of the intervention received by the other 2 comparison groups.
