Inclusion criteria
Inclusion criteria: A history of at least one ankle sprain, the first of which occurred at least 12 months ago, was accompanied by inflammatory symptoms (pain, swelling, etc.), disrupted the patient's normal physical activity for at least one day, and more than 3 months had passed since the last time A history of giving way and / or recurrent sprain in a previously injured ankle joint. Participants had to report at least 2 episodes of ankle sprain in the past 6 months Feeling of ankle joint instability. Regarding the person's feeling of instability of the ankle joint, if the score is less than 24 in the CAIT questionnaire, the score is less than 90% in the activities of daily living section, and the score is less than 80% in the sport activities section of the FAAM questionnaire, the patient enters the study People who are between 18 and 50 years old
Exclusion criteria
Exclusion criteria: History of previous surgery in the musculoskeletal system in one or both lower limbs History of fracture in one or both lower limbs Acute injury to other lower limb joints in the past 3 months that has disrupted the patient's normal physical activity for at least one day Contraindications of whole body vibration (pregnancy, acute bleeding, pacemaker, cardiovascular diseases, tumors, hip and knee implants, acute herniation of intervertebral discs, diabetes, and kidney stone) Contraindications of blood flow restriction (poor circulatory system, obesity, diabetes, arterial calcification, high blood pressure, kidney disorders, venous thromboembolism, peripheral vascular damage, sickle cell anemia, limb infection, lymphadenectomy, cancer or tumor, and medications that increase the risk of blood clots) Severe deformities of the spine and lower limbs Any peripheral and central nervous disease Middle ear diseases Rheumatic diseases

| Measure | Time frame |
|---|---|
| Balance. Timepoint: At the beginning of the study (before the start of the intervention) and 4 and 8 weeks after the start of the intervention. Method of measurement: Balance is evaluated using the modified Star Excursion Balance Test. This test is a modified and simplified version of the Star Excursion Balance Test that uses three directions: anterior, posterior-medial, and posterior-lateral. These three directions are marked by adhesive tapes on the floor. In this way, the angle between the anterior line and the posterior-medial line is 135 degrees, the angle between the anterior line and the posterior-lateral line is 135 degrees, and the angle between the posterior-medial line and the posterior-lateral line is 90 degrees. All participants stand without shoes and with their eyes open on the injured foot, with the big toe placed in the center of these three lines, and hands on their thighs. The participants with their good foot along each path touch the greatest distance they can with their big toe and the place where the big toe of the good foot touches the ground is marked and recorded by the examiner. Then, maintaining balance, the patient returns to the starting position, which is standing on two legs. They do this first in the anterior path, then in the posterior-medial path and finally in the posterior-lateral path. The contact of a healthy foot with the ground should be gentle and without bearing weight on it. For each route, the participants do 3 times of training and then rest for 5 minutes and then do the main test 3 times and 10 seconds of rest between each route is considered in the main test. The distance from the center of these three lines to the point of contact of the big toe of the healthy foot is measured in centimeters in each direction, and the average of the 3 main test times in each direction is calculated and the length of the person's lower limb (from the anterior-superior iliac spine to the inferior border of medial malleolus) is normalize | — |

| Joint position sense. Timepoint: At the beginning of the study (before the start of the intervention) and 4 weeks after the start of the intervention. Method of measurement: Active joint position sense is assessed using an isokinetic device (Biodex System 4 pro, Biodex Medical System Inc., Shirley, New York). Participants sit on the chair of the machine while the back of the chair is placed at an angle of 70 degrees, the involved lower limb is placed on the special connecting rod of the machine, the involved ankle is in a normal position, and the axis of the ankle joint is aligned with the machine axis. The person's trunk and lower limb are fixed with a belt, and the person's eyes are closed with a blindfold. The active sense of joint position is evaluated in two positions of 15 degrees of inversion and 10 degrees of eversion at a speed of 5 degrees per second. First, the involved ankle is placed in a neutral position. Then the device randomly places the person's ankle in the reference angle of inversion or eversion for 10 seconds and the person is asked to remember the angle. Then the device returns the person's ankle to the neutral position and the person is asked to actively reproduce the angle 3 times and the corresponding angles are recorded. The mean absolute error is used for statistical analysis.;Lower limb function. Timepoint: At the beginning of the study (before the start of the intervention) and 4 and 8 weeks after the start of the intervention. Method of measurement: Lower limb function is evaluated using the triple Hop test. A tape is drawn on the ground, perpendicular to the starting line. Participants stand on the involved foot while wearing athletic shoes, with the big toe on the starting line and their healthy foot in flexion without contact with the involved foot. Participants perform 3 maximum forward jumps while arm swing is allowed. If the person can land in a controlled and stable manner, the test is considered successful. To get familiar with | — |
