    Opis:
    The purpose of this study was to assess if 65 dB and 4000 Hz stimuli affect postural stability of young normal hearing people. Methods: Posturography examinations belong to clinical tests which evaluate the motor skills. Posturography can be divided into static posturography and dynamic posturography. In both, static posturography and dynamic posturography, patient stays on the platform with opened and closed eyes, but in the case of dynamic one, platform is unstable. In this study the Multitest Equilibre platform produced by FRAMIRAL was used. Patients took part in tests with opened and closed eyes, on stable and unstable platform. Additionally patients were exposed to 65 dB and 4000 Hz acoustic stimuli. The sound pressure level, and frequency was belonging to the best audibly frequency range. Results: Parameters such as velocity and surface were examined. The difference between velocity measured with acoustic stimuli and without acoustic stimuli was observed. On the other hand there was no difference in surface results. Conclusions: The statistically significant difference between velocity of patients center of gravity movements, measured on unstable platform, in the presence of 4000 Hz, 65 dB acoustic stimulus and without additional disturbances was observed.

    Opis:
    The human body balance system is a complex system of organs and mechanisms, which generate postural reactions to counter the displacement from the equilibrium position of the body centre of gravity, and which control eye movement in order to maintain a stable image of the environment. Computerised Dynamic Posturography (CDP) allows for a quantitative and objective assessment of the sensory and motor components of the body balance control system as well as of the integration and adaptive mechanisms in the central nervous system. The aim of this study was to determine the differences, when maintaining body balance, based on the gender of young, healthy people using CDP. The study was carried out on a group of 43 healthy subjects by comparing the effectiveness of the balance system in 22 women and 21 men aged between 20 and 26 years, between 171 and 177 cm in height, and without any clinical symptoms of balance disorders. The men and women were selected such that they did not differ significantly in height and BMI. Using the Equitest posturograph manufactured by NeuroCom International Inc. the following tests were performed: Sensory Organisation Test (SOT), Motor Control Test (MCT) and the Adaptation Test (ADT). The gender of young healthy individuals without any clinical symptoms of balance disorders also does not affect the effectiveness of the sensory system and the use of this signal in maintaining body balance.

    Opis:
    Disorders in the functioning of the human body balance system exist in 20-30 % of adults and in 8-18% of children. The main causes of these aberrations are: benign positional vertigoes, migraine, anxiety disorders and depression, cerebrovascular diseases, brain traumas, labyrinthitis, toxic impairment of labyrinth, vestibular neuronitis, Ménière disease, brain tumours. Among the minor causes of these disorders are: internal ear disorders, inner ear circulation disorders, sclerosis multiplex (SM), epilepsy, arterial hypertension, postural hypertension, heart rhythm disorders, sclerosis, hypoglycaemia and involutional alternations (see: prezbiastazja). Human body balance disorders increase the risk of falls, which may threaten health and life. Frequency of these disorders raises with age, which is the cause of progressing degeneration of all the anatomical and functional systems, the efficiency of which affects the stability of the human body. Determination of the factors, which are related to a worse functioning of the body balance system of young people, who do not experience any clinical symptoms caused by this system is vital, especially in preventing falls and complications attributed to them. It allows to implement possibly early the preventive actions substantial for people encumbered by the risk factors. The aforesaid actions may consist in the alternation of a given factor (diet, sleep, physical activity). In case of  the factors, which are not subject to modifications (i.e. heterogeneous form of the functional lateralization), it is essential to prevent potential diseases that disturb the functioning of the body balance system, which is already impaired. This study aimed to acquaint with the findings concerning the evaluation of the functional lateralization enriched with a new diagnostic tool – a computerized dynamic posturography. The computerized dynamic posturography (CPD) is a state-of-the-art and faultless evaluation tool of the functional lateralization. It provides a comprehensive knowledge, which concerns not only the preferences of the body, but also constitutes an objective and quantitative diagnostic method for the disorders in the functioning of the body balance system. CPD differentiates a few clinical protocols: the Sensory Organization Test (SOT); the Motor  Control Test (MCT); the Adaptation Test (ADT). SOT evaluates the control of the body balance in different conditions (eyes closed/eyes opened;  environment moves/ground moves) of the sensory systems stimulation. MCT assesses the postural reactions (body postures) in response to an unexpected changes in the location of the feet prop surface. ADT  assesses the efficiency of the adaptation mechanisms in the body balance control.

    Opis:
    The human body’s posture control is a complex system of organs and mechanisms which controls the body’s centre of gravity (COG) over its base of support (BOS). Computerised Dynamic Posturography (CDP) allows for the quantitativeand objective assessment of the sensory and motor components of the body’s posture control system as well as of the integration and adaptation mechanisms in the central nervous system. The aim of this study was to assess the relationships between the body’s height and BMI on CDP results in a group of young healthy women without any clinical symptoms of balance disorders. It was found that the MS depended significantly on the height and BMI of the subjects as well as on the SOT conditions. As the height and BMI increased the MS value decreased. The postural response latency (LC) in the MCT statistically significantly depended only on height and showed a positive correlation. The postural response latency increased with height. The postural response amplitude for both right and left lower limbs significantly depended on height and BMI, but only for the backward movement of the platform. The response amplitude for all platform translations under all MCT conditions increased with height and BMI. The body’s resultant imbalance caused by the platform perturbations in the ADT were greater in shorter people and those with a lower BMI.

    Opis:
    Introduction: The ability to Reach quickly to changing external stimuli, to move the body quickly and precisely in any direction and to maintain the centre of gravity above the support base, all contribute to maintaining balance in dynamic conditions. The Limits of Stability Test (LOS) provides information on the state of dynamic equilibrium in a standing position. Aim : Assessment of dynamic postural control in developmental age. Material : 127 healthy children (65 girls and 62 boys) aged 6 – 17years. Methods: All children underwent LOS test (posturograph NeuroCom) with registration of reaction time (RT), movement velocity (MVL), directional control (DCL) , maximum excursion (MXE) and endpoint excursion (EPE). Results: At the age of 6-7 years, not fully developed jumping strategy and visual feedback mechanism in the control of movement were observed. All tested parameters were significantly worse in children aged 6 – 9 years. After this period, a significant improvement in TR and MVL was observed, with no significant changes in subsequent age groups while significant improvement in MXE up to 12 , EPE and DCL up to 13 years of age was noted. No significant gender differences were fund in the LOS test parameters. Conclusions: 1 The LOS test showed significantly lower dynamic balance development in children aged 6 – 7 years. 2 The study showed a significant improvement in all parameters of the LOS test up to 13 years of age, which supports the termination of the function at that time.

    Opis:
    Introduction: Proper development of postural control in children is connected with the maturation of the central nervous system, development of sensory organisation with appropriate use of proprioceptive, visual, vestibular information as well as reactions and postural strategy which allow the maintenance of balance in changeable environmental conditions. Developmental disturbances in this particular area is reflected in postural disfunctions and the assessment of these disfunctions and disturbances needs referring to normative values of the healthy population of children. Aim: Examination of postural control development in children aged 6–17 years. Material: 127 healthy children were tested (65 girls and 62 boys) aged 6–17 years. Method: Laryngological investigation, medical history interview, audiometry and tympanometry were conducted in all children. In the evaluation of postural control (mCTSIB-modified Clinical Test For The Sensory Interaction On Balance) a computer posturography system was used (Balance Master Neurocom). R esults: Further development of postural control was found in healthy children up to the age of 13 years of age. The development was not linear but showed transient characteristics with a faster development stage between the age of 6–7 and 8–9. Better postural control in girls, particularly the youngest, in comparison with boys was noticed. C onclusions: 1. The values of norm postural control in posturographic test mCTSIB in children aged 6–17 was established. In this test postural control development was completed in children before 13 year and it was not linear. 2. Due to gender differences it seems appropriate to use separate norms in order to evaluate the development of postural control in boys and girls.

    Opis:
    Wstęp W ocenie układu równowagi istotne znaczenie mają objawy, zaburzenia w badaniu klinicznym i czynnościowym oraz ich weryfikacja w testach obiektywnych. Celem pracy było określenie zgodności oceny kwestionariuszowej i funkcjonalnej z badaniami obiektywnymi. Materiał i metody Badaniem objęto 131 pacjentów poradni audiologicznej (średni wiek: 59±14 lat), w tym 101 kobiet. Wśród rozpoznań klinicznych dominowały łagodne położeniowe zawroty głowy, zawroty psychogenne i zawroty pochodzenia ośrodkowego. Objawy oceniano, korzystając z kwestionariusza dotyczącego ćwiczeń Cawthworne’a-Cookseya (CC), kwestionariusza DHI (Dizziness Handicap Inventory) i Skali Lęku-Depresji Duke’a. Do oceny czynnościowej zastosowano Skalę Równowagi Berg (Berg Balance Scale – BBS), dynamiczny indeks chodu (dynamic gait index – DGI), test Tinetti, test TUG (Timed Up and Go – „wstań i idź”) oraz test dynamicznej ostrości wzroku (DOW). Badania laboratoryjne obejmowały próbę kaloryczną i posturografię statyczną. Wyniki Wyniki BBS, DGI, TUG i DOW wykazały istotną statystycznie, lecz umiarkowaną zgodność z wynikami badań obiektywnych – zarówno próby kalorycznej (W Kendalla = 0,29), jak i posturografii statycznej (W = 0,33). Dla badań kwestionariuszowych zgodność ta była bardzo niska (W = 0,08–0,11). Wartości predykcyjne dodatnie dla skali BBS wynosiły 42% (próba kaloryczna) i 62% (posturografia), dla DGI odpowiednio: 46% i 57%. Wnioski Wyniki testów czynnościowych BBS, DGI, TUG i DOW wykazują istotną statystycznie zależność od badań obiektywnych, jednak niskie wartości predykcyjne nie pozwalają na zastosowanie tych testów jako screeningowych dla zaburzeń przedsionkowych. Jedynie połowa osób, u których stwierdzono zaburzenia funkcji układu równowagi w testach czynnościowych, ma nieprawidłowe wyniki próby kalorycznej i/lub posturografii statycznej. Kwalifikując do pracy na podstawie wyników badań obiektywnych, pomija się zaburzenia funkcjonalne, które mogą wpływać na zdolność do wykonywania pracy. Med. Pr. 2018;69(2):179–189
    Background Balance assessment relies on symptoms, clinical examination and functional assessment and their verification in objective tests. Our study was aimed at calculating the assessment compatibility between questionnaires, functional scales and objective vestibular and balance examinations. Material and Methods A group of 131 patients (including 101 women; mean age: 59±14 years) of the audiology outpatient clinic was examined. Benign paroxysmal positional vertigo, phobic vertigo and central dizziness were the most common diseases observed in the study group. Patients’ symptoms were tested using the questionnaire on Cawthworne-Cooksey exercises (CC), Dizziness Handicap Inventory (DHI) and Duke Anxiety-Depression Scale. Berg Balance Scale (BBS), Dynamic Gait Index (DGI), the Tinetti test, Timed Up and Go test (TUG), and Dynamic Visual Acuity (DVA) were used for the functional balance assessment. Objective evaluation included: videonystagmography caloric test and static posturography. Results The study results revealed statistically significant but moderate compatibility between functional tests BBS, DGI, TUG, DVA and caloric results (Kendall’s W = 0.29) and higher for posturography (W = 0.33). The agreement between questionnaires and objective tests were very low (W = 0.08–0.11).The positive predictive values of BBS were 42% for caloric and 62% for posturography tests, of DGI – 46% and 57%, respectively. Conclusions The results of functional tests (BBS, DGI, TUG, DVA) revealed statistically significant correlations with objective balance tests but low predictive values did not allow to use these tests in vestibular damage screening. Only half of the patients with functional disturbances revealed abnormal caloric or posturography tests. The qualification to work based on objective tests ignore functional state of the worker, which may influence the ability to work. Med Pr 2018;69(2):179–189
