What is being measured
The primary outcome is the main question the study is designed to answer.
Modified-CTSIB
Modified-CTSIB; It is generally used as a semi-quantitative test measurement and clinical practice in which points are scored based on the ability to perform various standing static positions It is a test. It covers different situations where the patient must stand under different conditions: foam surface versus hard floor, tested with eyes open and closed in six different test groups.
Measured: 30 minutes
Semitandem test
semitandem stance positions; The conditions (sec) of remaining in balance with eyes open and closed on hard and soft surfaces will be measured.
Measured: 10 minutes
tandem test
tandem semitandem stance positions; The conditions (sec) of remaining in balance with eyes open and closed on hard and soft surfaces will be measured.
Measured: 10 minutes
one-leg standing test
one-leg standing test; The conditions (sec) of remaining in balance with eyes open and closed on hard and soft surfaces will be measured.
Measured: 10 minutes
Unterberger test
Unterberger test: The patient first takes 10 steps quickly with his eyes open, then With his eyes closed, he takes 50 steps quickly in place. If there is a lesion, apply it to the side of the lesion.
correct deviation occurs.
Measured: 5 minutes
VAS Visual Analogue Scale (dizziness severity)
Visual Analogue Scale will be applied to evaluate dizziness severity and patient satisfaction. With this scale, scoring from 0 to 10 is requested. While 0 indicates the lowest dizziness severity and lowest patient satisfaction, 10 indicates the highest dizziness severity and highest patient satisfaction.
Measured: 5 minutes
Dynamic visual acuity test
Dynamic visual acuity test; It measures the ability to see an object during rapid head movements.
Measured: 5 minutes
Secondary outcomes (3)
Dizziness Handicap Inventory Scale
It was developed to measure disability in patients complaining of dizziness and imbalance and is used in treatment follow-up. It is a survey consisting of 25 questions about the patient's physical (7 questions), functional (9 questions) and emotional (9 questions) status, and which patients can apply themselves in line with their complaints. Patients rate the questions as 0 (no), 2 (sometimes) and 4 (yes) based on their complaints. high scores describe severe dizziness.
Measured: 5 minutes
Tampa Kinesiophobia Scale
The Tampa Kinesiophobia Scale will be used to evaluate kinesiophobia. It is a 17-question scale developed to measure fear of injury. The scale includes injury/re-injury and fear-avoidance parameters in work-related activities. High scores describe severe kinesiophobia.
Measured: 5 minutes
Hospital Anxiety and Depression Scale (HAD)
The Tampa Kinesiophobia Scale will be used to evaluate kinesiophobia. It is a 17-question scale developed to measure fear of injury. The scale includes injury/re-injury and fear-avoidance parameters in work-related activities. High scores describe higher levels of depression and anxiety.
Measured: 5 minutes

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2025; AzTrials last refreshed its copy on 8 Nov 2026.
