Protocol summary

Study aim
Comparison of plyometric training with and without EMS on motor performance, postural control and strength of athletes with ankle instability
Design
36 female athletes with functional ankle instability divided into two experimental and one control groups. The simple randomization method was used to assign individuals to groups that in this method, random allocation software was used to create a random sequence.
Settings and conduct
The present study is a quasi-experimental research with a pre-test - post-test design. 36 Female Athletes with Ankle Instability randomly divided into two experimental and one control groups. Motor performance, postural control and strength are measured before and after exercises.
Participants/Inclusion and exclusion criteria
Athletes with ankle instability; age range 18 to 26 years old; at least once ankle sprain in the last 6 months; pain intensity calculated from the Pain Scale Test (VAS) at least 4.
Intervention groups
The first intervention group included female athletes with ankle instability who received a plyometric exercise intervention. The second intervention group included female athletes with ankle instability who received the intervention of plyometric exercises with electrical muscle stimulation (EMS). The control group included female athletes with ankle instability who did not receive any intervention.
Main outcome variables
Motor performance; Postural control; Strength

Randomization description
The simple Randomization Method was used to assign individuals to three groups that in this method, Random Allocation Software was used to create a random sequence. Then, in order not to determine which group the individuals will be assigned to before dividing them into two groups, or in other words, allocation concealment, the central randomization method was used.
