Differentiation of Human Body Balance Disorders

Differentiation of Human Body Balance Disorders - Analysis of the Potential of Functional Tests in Determining the Cause of Disorders

Our research aims to analyze the possibilities of functional assessment of imbalances in the human body. Using the available, commonly known and used tests and devices for objective examination of static and dynamic body balance, as well as changes in the tension of selected muscles of the cervical spine in static and dynamic conditions, depending on visual control or its absence, we hope to identify important research tools that help to differentiate the causes of imbalances. Studies conducted on a group of healthy people and groups of patients: after a stroke, with changes in the posterior cords of the spinal cord, with labyrinth disorders, with degenerative changes in the spine, with visual impairments, and in healthy people, seem to be important in the analysis of the discussed topic. The investigators will answer the following detailed research questions: 1. Does the type of disease/disease or its absence affect the human balance in the Romberg test? 2. Do visual defects affect the tension of the muscles of the cervical spine? 3. Do changes in the muscle tension of the cervical spine affect the ability to maintain balance in the Unterberger test? 4. Do the mobility deficits in the cervical spine coincide with cervical or labyrinthine balance disorders in the differential test for vertigo and in the Fukuda test? 5. How does the tension of the muscles of the cervical spine change in the tested groups on the stable and unstable, depending on the vision control? 6. Does the type of disease/illness or its absence affect changes in the tension of the muscles of the cervical spine, and does it correlate with the balance of the body on a stable and unstable surface? The results of the research may facilitate the functional differentiation of imbalances in the human body. The investigators hypothesize that functional tests will help determine the cause of imbalance in the human body. This will allow us to determine with high probability the dominant cause of balance disorders (eye disorders, changes in the cervical spine / musculoskeletal system, labyrinth, proprioceptors, cerebellum, posterior cords of the spinal cord), already at the initial stage of diagnosis. The research will improve the process of implementing effective treatment and therapeutic procedures.
