Immediate Effects of Blood Flow Restriction Combined with Whole Body Vibration on Balance and Proprioception in Non-professional Athletes with Chronic Ankle Instability

Investigating the immediate effect of blood flow restriction combined with whole body vibration on balance and proprioception of non-professional athletes with chronic ankle instability

Clinical trial with control group, with parallel groups, double-blind, randomized, on 38 patients with sealed envelope method.

The samples and the assessor are blinded to the treatment group.

Inclusion criteria 1- Non-professional athlete 2- Age range from 18 to 35 years 3- Male and female gender 4- Having at least one ankle sprain in one of the legs, the first history of the sprain occurred at least one year before the study and was associated with inflammatory symptoms and caused the person to be unable to participate in desired physical activities for at least one day. slow 5- A score less than or equal to 24 in the Cumberland questionnaire 6- Having a history of ankle giving way or recurrent ankle sprain or a feeling of instability in the injured ankle exclusion criteria 7- history of acute injury (including sprained ankle), fracture or lower limb surgery in the last 3 months 8- having any disease (vestibular problem, vision and hearing disorders, etc.) that affects the person's balance 9- history of hypertension, blood clotting disease, peripheral vascular disease, cardiovascular problems or diabetes 10- People with internal prosthesis, acute disc herniation, recent fracture, joint inflammation, recent stroke, having an artificial pacemaker, epilepsy, migraine, peripheral neuropathy, pregnancy and malignancy are excluded from the study.

1- Blood flow restriction group in combination with whole body vibration 2- Whole body vibration group alone

1- Reaching distance in star excursion balance test 2- Number of errors in balance error scoring system 3- Ankle joint repositioning error

Simple non-probability randomization is done using the numbered and sealed envelope method. With the help of physiotherapist 1 (evaluator), patients are randomly divided into 2 intervention and control groups through the sealed envelope method. be. For this purpose, 38 envelopes are prepared, which are filled with the numbers 1 and 2 (19 envelopes containing the number 1 and 19 envelopes containing the number 2). The numbers 1 and 2 each separately means entering one of the intervention and control groups, which only physiotherapist 2 (therapist) knows about. Before the patient chooses the envelope, we will change the order of the envelopes several times, and after the patient chooses the envelope, its number is noted on the evaluation sheet.

The participants and the evaluating physiotherapist are blinded to the study groups. Both groups of patients receive whole body vibration treatment, and in one group, the cuff around the thigh is filled with air, and in the other group, it is simply closed without filling with air, and the patients do not see any difference between the two groups. The evaluating physiotherapist does not know which treatment group each patient is in, and the assignment of patients to two groups is done by the treating physiotherapist.

All data is potentially shareable after de-identifying individuals
