20.500.12556/RUL-184285 Dolgoročni vpliv lateralnega zvina gležnja na dinamično stabilnost sklepa in občutek njegove nestabilnosti pri aktivnih košarkarjih magistrsko delo Long-term impact of lateral ankle sprain on dynamic stability and percieved ankle instability in active basketball players master thesis Uvod: Lateralni zvin gležnja spada med najpogostejše mišično-skeletne poškodbe v športu in velja za eno najbolj ponavljajočih se poškodb spodnjih udov. Velik vpliv na incidenco lateralnih zvinov gležnja ima predvsem vrsta športne aktivnosti, saj je največja verjetnost za poškodbo prisotna pri športih z veliko teka, spreminjanja smeri in skakanja, kar so glavni elementi košarke. Pri večkratnih zvinih gležnja pride do zmanjšane funkcijske zmožnosti in občutka nestabilnosti v gležnju, kar lahko privede do kronične nestabilnosti gležnja. Namen: Namen magistrskega dela je raziskati dolgoročni vpliv lateralnega zvina gležnja na dinamično stabilnost sklepa in občutek njegove nestabilnosti pri aktivnih košarkarjih. Metode dela: Izvedli smo primerjalno raziskavo posameznika (ang. within-subject comparative study) z enkratnim testiranjem polnoletnih aktivnih košarkarjev iz različnih slovenskih košarkarskih klubov, ki so utrpeli enostranski lateralni zvin gležnja. Dinamično stabilnost gležnja smo ocenjevali z Y-testom ravnotežja, občutek nestabilnosti pa s Cumberlandovim vprašalnikom o funkcionalni nestabilnosti gležnja, prevedenim v slovenščino. Rezultati: V raziskavi je sodelovalo 25 košarkarjev iz osmih različnih klubov. Rezultati dinamičnega ravnotežja v nobeni izmed smeri niso bili statistično značilni in so se med poškodovanimi in nepoškodovanimi gležnji razlikovali v anteriorni smeri za 2,1 % (p=0,029), v posterolateralni smeri za 1,1 % (p=0,467) in v posteromedialni smeri za 2,2 % (p=0,159). Občutek nestabilnosti gležnja se je med skupinama statistično značilno razlikoval in je po vprašalniku CAIT znašal pri poškodovanih gležnjih 23,8 točke, pri nepoškodovanih pa 27,8 točke (p<0,001). Razprava in zaključek: Na podlagi rezultatov meritev dinamičnega ravnotežja lahko rečemo, da nismo ugotovili statistično značilnih razlik med poškodovanim in nepoškodovanim gležnjem košarkarjev pri Y-testu ravnotežja. Statistično značilne razlike smo ugotovili med poškodovanim in nepoškodovanim gležnjem pri ocenjevanju občutka nestabilnosti z vprašalnikom CAIT. Dodatno smo na našem vzorcu mladih košarkarjev ugotovili, da so nižji igralci in tisti, ki so utrpeli prvi lateralni zvin gležnja bolj zgodaj v adolescenci, imeli večje število zvinov. Pri primerjavi med zvini, ki so se zgodili pred manj kot letom, in tistimi, ki so se zgodili pred več kot letom dni, nismo ugotovili pomembnejših razlik. V prihodnje bi bilo smiselno izvesti raziskavo na večjem vzorcu košarkarjev, ki so bolj primerljivo trenirani in so imeli enako stopnjo zvina, da bi z meritvami bolj usmerjeno ugotavljali nestabilnost gležnjev. Introduction: Lateral ankle sprain is among the most common musculoskeletal injuries in sports and is considered one of the most recurrent injuries of the lower extremities. The incidence of lateral ankle sprain is strongly influenced by the type of sport, with the highest risk observed in activities involving frequent running, changes of direction, and jumping, which are key elements of basketball. Recurrent ankle sprains may lead to reduced functional ability and perceived ankle instability, which can potentially result in chronic ankle instability. Purpose: The aim of this master’s thesis was to investigate the long-term effects of lateral ankle sprains on dynamic stability and perceived ankle instability in active basketball players. Methods: A within-subject comparative study design with a single testing session was conducted among adult active basketball players from various Slovenian basketball clubs who had sustained a unilateral lateral ankle sprain. Dynamic ankle stability was assessed using the Y-balance test, while percieved ankle instability was evaluated using the Slovenian-translated version of the Cumberland’s ankle instability tool. Results: The study included 25 basketball players from eight different basketball clubs. Differences in dynamic balance between injured and uninjured ankles were 2,1% (p=0,029) in the anterior direction, 1,1% (p=0,467) in the posterolateral direction, and 2,2% (p=0,159) in the posteromedial direction. The mean CAIT score for injured ankles was 23,8 points, compared to 27,8 points for uninjured ankles (p<0,001). Discussion and conclusion: No statistically significant differences were found in posterolateral direction between the injured and uninjured lower limb. However, a statistically significant reduction in percieved ankle instability was observed in previously injured ankles, confirming the second hypothesis. Within our sample of young basketball players, shorter individuals and those who sustained their first lateral ankle sprain earlier in adolescence experienced a higher number of sprains. No significant differences were found when comparing sprains that occurred less than one year prior to those occurring more than one year earlier. Future research should be conducted on a larger sample of basketball players with comparable training backgrounds and a similar grade of lateral ankle sprain, which would enable a more accurate evaluation of ankle instability and a more reliable interpretation of the measured outcomes. magistrska dela fizioterapija lateralni zvin gležnja košarkarji dinamična stabilnost občutek nestabilnosti gležnja Y-test ravnotežja Cumberlandov vprašalnik za oceno funkcionalne nestabilnosti gležnja master's theses physiotherapy lateral ankle sprain basketball players dynamic stability perceived ankle instability Y-balance test Cumberland’s ankle instability tool true false false [N.
