Comparison of a course of plyometric exercises with feedback and combined exercises (neuromuscular ، central stability) on maximum knee flexion angle, maximum vertical ground reaction force during landing and balance female athletes with chronic ankle instability
Ankle is one of the most common joints that get injured in sports.
This type of injury puts the athlete back from training sessions and competitions. Especially in sports such as football, basketball and other sports that require running, jumping and many landings. Also, due to the chain structure and connection of body parts, if this complication is not paid attention to, pain and other disorders in the knee area and ... involves a person. As a result, we study the effect of plyometric and combined exercises (neuromuscular-central stability) as rehabilitation in these people.
Design
The type of current research is experimental. The research model is a randomized clinical trial with a three-group design. The research design is intergroup pre-test - post-test. This research has three groups (control group, plyometric exercises group and combined exercises group (neuromuscular - central stability)). The sample size was purposefully estimated with G*Power 3.1.7 software (University of Dusseldorf, Germany) considering high power (0.8), average effect size (0.28) and alpha (0.05) of 30 patients.
Settings and conduct
The research was carried out in the physical training laboratory of Kharazmi University, Karaj branch. Treatment protocols are in groups for 8 weeks (three days per week and 40 minutes per day).
Participants/Inclusion and exclusion criteria
Score less than 24 in the Cumberland Ankle Stability Instrument (CAIT)
1: Any damage and abnormality affecting the research
Intervention groups
They are randomly divided into 3 groups, the first group is plyometric exercises with feedback, the second group is combined exercises (neuromuscular-central stability) and the third group is the control group that does not receive therapeutic intervention and engages in their daily and sports activities.
Main outcome variables
Identifying better exercise therapy for ankle instability

Randomization (investigator's opinion)
Randomized
Randomization description
The samples were divided into two groups based on the criteria for entering the research in a purposeful and simple random manner. Randomization is done based on blocks of four. A series of consecutive numbers that are generated by the number table in the computer. They are randomly placed in opaque envelopes, a person blind to patients and intervention groups performs randomization and assignment of numbers to groups. Also, patients in each group are blinded to the way of randomization and intervention performed in the other group.
Blinding (investigator's opinion)
