Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to examine the effects of ankle taping on improving muscle function and ankle motion in individuals who frequently twist (sprain) their ankle. It is thought that ankle taping may increase muscle function and ankle motion which would benefit individuals who frequently sprain their ankle.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Previous research has demonstrated improved dynamic balance following the application of fibular taping. The effects of fibular taping on ankle dorsiflexion ROM and muscle activation in individuals with CAI are unknown. The purpose of this study is to determine the acute effects of fibular taping on muscle activation of the fibularis longus (peroneus) and soleus muscles, ankle dorsiflexion range of motion (ROM) and dynamic balance. The investigators hypothesize that fibular taping will have similar effectiveness as mobilization interventions which have been shown to improve muscle activation, ankle dorsiflexion ROM,and dynamic balance. Outcomes will be measured immediately before and after intervention. A crossover design will be used and participants will complete two visits at least 48 hours apart, but not more than 1 week apart. After participants complete both arms of the study their participation will be complete (average time to completion for each subject is 1 week).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Fibular Taping

With the ankle in a neutral position, two strips of nonrigid hypoallergenic tape will be applied beginning at the distal aspect of the fibula, wrapping around the posterior aspect of the leg, and finishing superior and medial to the starting point. Next,a strip of rigid zinc oxide tape will be applied to the distal aspect of the fibula with tension.

Group Type EXPERIMENTAL

Fibular Taping

Intervention Type OTHER

Tape with be applied with tension.

Sham Taping

Sham taping will be applied in the same manner as the fibular taping, but tension will not applied to the zinc oxide tape

Group Type SHAM_COMPARATOR

Sham Taping

Intervention Type OTHER

Tape will be applied without tension
