Uvod: Ravnotežje je sposobnost ohranjanja telesnega težišča nad podporno ploskvijo, ki ga kompleksni senzomotorični sistemi učinkovito uravnavajo s pomočjo senzoričnega priliva iz vidnega, proprioceptivnega in vestibularnega sistema. Test za oceno statičnega ravnotežja (angl. Balance error scoring system, BESS) je prenosen, poceni in objektiven klinični test, ki je bil razvit za oceno učinkov blage poškodbe glave na statično ravnotežje. Pritiskovna plošča nam omogoča sočasno merjenje gibanja središča pritiska (SP) med izvajanjem testa. Namen: Namen diplomskega dela je ugotoviti korelacije med številom napak pri posamezni nalogi BESS in gibanjem središča pritiska pri zdravih mladih osebah. Metode dela: Sodelovalo je 17 mladih zdravih oseb (21,0 ± 0,94 let), z odsotnostjo poškodbe spodnjih udov in pretresa možganov v zadnjih šestih mesecih pred raziskavo. Testiranje se je izvajalo v Biomehanskem laboratoriju s pomočjo pritiskovne plošče Kistler 9286 AA, na kateri smo izvajali BESS. Test sestavljajo trije položaji pri zaprtih očeh (stoja s stopali skupaj, stoja na eni nogi in stoja stopalo pred stopalo) na dveh različnih površinah (trda in mehka podlaga). Vsaka meritev je trajala 20 sekund pri frekvenci vzorčenja gibanja SP 200 Hz, pri kateri smo opazovali spremenljivke poti mediolateralno (ML) in anteroposteriorno (AP) ter hitrost. Za izračun korelacij med gibanjem SP in številom točk smo uporabili Spearmanov koeficient korelacije. Rezultati: Pri položaju s stopali skupaj na trdi in mehki podlagi ni bilo možno izračunati korelacij, saj so vsi preiskovanci naredili 0 napak. Število točk pri vseh ostalih položajih testa BESS zmerno do močno korelirajo z gibanjem SP, razen pri stoji na eni nogi na mehki podlagi, ki šibko korelira. Gibanje SP pri položajih na trdi podlagi je imelo s skupnim številom točk BESS zmerno do močno korelacijo, medtem ko je bila korelacija na mehki podlagi šibka, z izjemo hitrosti in poti ML gibanja SP pri položaju na eni nogi na mehki podlagi, ki sta bili močni. Razprava in zaključek: Raziskava je pokazala, da število točk pri vseh položajih, razen pri stoji s stopali skupaj, pri katerih je zaznan učinek tal, zmerno do močno korelirajo z gibanjem SP. Izjema je le stoja na eni nogi na mehki podlagi, ki šibko korelira. Podobno je bilo ugotovljeno tudi v dosedanjih študijah. Gibanje SP pri stoji na eni nogi na trdi podlagi ima najmočnejše korelacije s številom točk naloge in s skupnim številom točk, kar nam omogoča, da lahko posameznike z oslabljenim ravnotežjem in ob pomanjkanju časa testiramo samo v tem položaju. V prihodnje bi bilo smiselno preučiti vpliv različnih športov na izid, korelacije med gibanjem SP in vrsto napake pri BESS ter vpliv starosti (nad 65 let) na skupno število točk.

Sekundarni naslov: ǂThe ǂcorrelation between performance on Balance error scoring system and postural sway stability
Sekundarni povzetek: Introduction: Balance is the ability to maintain the center of gravity above the support surface. Complex sensorimotor systems are responsible for the effective maintenance of the balance with the help of sensory input from the visual, proprioceptive and vestibular systems. Balance Error Scoring System (BESS) is a portable, cheap and objective clinical test, primarily developed to assess the effects of mild head injury to the balance. A force plate enables us to measure the movement of the center of pressure (COP) simultaneously during the testing. Purpose: The purpose of this diploma work was to determine the correlations between the number of errors and the movement of COP in each task amongst healthy young individuals. Methods: 17 healthy young individuals (21,0 ± 0,94 years) without any injuries in the lower limb and head concussions in the past six months prior were included in the study. The testing was conducted in the Biomechanical laboratory with a force plate Kistler 9286 AA, on which BESS was carried out. The test consists of three stances with eyes closed (double, single, tandem leg stance) on two different surfaces (firm and foam surface). Each task lasts 20 seconds at a sampling frequency of 200 Hz, with which we observed the variables anteroposterior and mediolateral path and speed of the COP. Spearman’s rank correlation coefficient was used to determine the correlations between the movement of COP and the number of errors at each task. Results: Double-leg stance on firm and foam surface did not allow us to calculate the correlations due to zero errors made by each participant. The number of errors in other tasks had moderate to very strong correlations with the movement of COP, with the exception of single leg stance on the foam surface, which had a weak correlation. The movement of COP in stances on firm surface had moderate to strong correlations with the total number of errors, whereas the correlations on foam surface were weak, with the exception of speed and mediolateral path of movement of COP in single leg stance on foam surface, which had a strong correlation. Discussion and conclusion: The research showed that the number of errors in each task, despite the double leg stances, which have a floor effect, correlates strongly to very strongly with the movement of COP, with the exception of the single leg stance on foam surface, which has a weak correlation, similar to previous studies. Movement of COP in single leg stance on foam surface has the strongest correlations with the task and the total number of errors, which enables us to evaluate the individuals with poor balance in shortage of time only in this stance. Future researches should investigate the effects of different sports on the total BESS score, correlations between the movement of COP and the type of errors and the effects of age (above 65) on total BESS score.
