The effect of agility ladder and hop training exercises on dynamic balance and functional tests in semi professional athletes with chronic ankle instability
Evaluation of the effect of 6 weeks of hop exercises and agility ladder exercises on dynamic balance using star balance test and functional tests in people with chronic ankle instability.
Design
Samples are randomly assigned to one of the two groups of agility ladder exercises and hop exercises equally by the restricted randomization and law of random allocation (drawing a card from the number of cards equal to the sample size (30 people)
The trial design will be done in parallel.
Settings and conduct
This study includes two types of agility ladder and hop exercises that are given to participants with chronic ankle instability for 6 weeks and 3 times a week, Accurate evaluation is done before and after 6 weeks, functional tests are taken to evaluate the effectiveness of the exercises. Before starting the exercises, the person does warm-up exercises, and then the main treatment exercises and finally cooling down.

Inclusion criteria:
In the age range of 18 to 35 years.
Regular exercise 3 days a week.
At least one ankle sprain that has caused pain, swelling, and dysfunction for more than a year .
At least two episodes in the last 6 months.
90% or less score in FAAM questionnaire .
Exclusion criteria:
Ankle sprains in the last 6 weeks.
Ankle surgery
Vision problems .

Intervention groups
Intervention group: Hop exercises are a modified type of plyometric exercises. These exercises also improve dynamic balance. Hop exercises are a type of exercise that is similar to basic and dynamic movements in many sports.
Agility ladder is used in various sports to improve performance, improve acceleration, speed, coordination, dynamic balance, static and maintain body posture.
Main outcome variables
Improve dynamic balance and ankle function in people with chronic ankle instability

Description
Hop exercises are a modified version of plyometric exercises and have recently been used to reduce ankle instability. These exercises are relatively inexpensive, so it is easy to use in exercises. These exercises also improve dynamic balance .Hop exercises are a type of exercise that is similar to basic and dynamic movements in many sports. It also improves functional and postural control in people with chronic ankle instability. In hop exercises, the athlete exercises 3 days a week for 6 weeks. The athlete runs 5 minutes in each session to warm up at the beginning of the training session, 5 minutes of dynamic stretching, and 5 minutes of cooling at the end .The exercises get harder every week, the level of reliance changes and the number of repetitions and sets increases, the person first has his hands free and then puts his hands on his chest and finally behind his head. There is a 30 second break between sets and a 1 minute break between workouts .The exercises are done in front of a mirror and the person has both visual and auditory feedback (the person is told about his mistakes and is motivated).Hop exercises include the following exercises (the exercises are randomly in the text below) . Forward hopping Hopping in 4-square shape Hopping side to side Hopping forward and back ward Hopping in zigzag shape Hopping in figure-8 shape

Description
Intervention group: Agility Ladder: An agility ladder is an inexpensive and accessible device that is placed on the ground like a ladder and the person moves one or two feet in and out of it. Depending on the purpose, it can be made of different lengths and widths. It can also be made using a tape or rope. The person also maintains his or her balance while moving rapidly, which is used in various sports to improve performance, improve acceleration, speed, coordination, dynamic balance, static, and body posture. Two of its most important goals are to improve coordination and speed, and the agility ladder is the best way to teach movement patterns. For best results, the exercises should progress from easy to difficult. Also, in the type of exercises, the type of sports activity of the person should be considered. The second group receives agility ladder exercises that they do 3 times a week for 6 weeks. Before training, they run for 5 minutes and do 5 minutes of dynamic stretching and warm up. The training lasts for 10 minutes and at the end, they cool down for 5 minutes. The exercises become more difficult as the progress progresses and the number of sets and repetitions varies, with 30 seconds between repetitions and 1 minute rest between sets. The exercises are as follows: Lateral two in two out Two in the hole Two in lateral One lateral Lateral ickey shuffle ickey shuffle backward ickey shuffle frontal two in two out forward zigzag cross over shuffle zigzag cross over shuffle backward frontal two in two out backward
