Effect of 6 Week Plyometric Training with Feedback on Lower Extremity Kinematic and GRF Symmetry on Drop Landing Technique of Male Basketball Players with Chronic Ankle Instability
Effect of 6 week plyometric trainig with feedback on lower extremity kinematic and GRF symmetry on drop landing technique of male basketball players with chronic ankle instability
Design
Randomized control trial with control group, with parallel groups, single blinded
Settings and conduct
Twenty four basketball players suffering from chronic ankle instability qualified to participate in the study will be assigned in two groups (experimental and control). Plyometric exercises will be conducted in fifty-minute sessions for three sessions a week and for six weeks. Participants will do the warm-up for ten minutes followed by plyometric exercises along with feedback (external manual) for thirty minutes, and the last ten minutes for cooling down.
Participants/Inclusion and exclusion criteria
Inclusion conditions:
1- At least having one experience of acute ankle sprain resulted in pain, swelling, and temporary reduction in performance (not in the last three months)
2-Having score less than 27 in Cumberland Ankle Instability Tool
3- Experience of repetitive giving way during the last six months
Exclusion conditions:
1- No consent to participation in the research
2- Absent more than three times during the exercises
3- Experience of any influential damage and malformation in researching lower limbs
4- Balance disorders (not resulting from chronic ankle instability)
5- Attending in rehabilitation programs during the last six months
Intervention groups
intervention: Plyometric training with feedback
control: They continue their routine basketball exercises
Main outcome variables
Knee flexion angle, Knee valgus angle, GRF symmetry, drop time symmetry

Randomization (investigator's opinion)
Randomized
Randomization description
The sample will be categorized into two groups including purposeful and simple random groups based on research participation scales.
Randomization is based on four blocks. A series of consecutive numbers generated by the computer's table of numbers. They are randomly placed in opaque envelopes, one blind to patients and intervention groups, randomizing and assigning numbers to groups. Patients in each group were also blinded to randomization and intervention in the other group.
Blinding (investigator's opinion)
Single blinded
