Simetrija spodnjih udov pri testih skokov in ocena dinamičnega valgusa kolenskega sklepa pri rokometašicah : magistrsko delo

Hren, Pia (avtor), Vauhnik, Renata (mentor)

Uvod: Glede na trenutne dokaze v literaturi, razlika v simetriji spodnjih udov pri zdravih športnikih ne sme presegati 10 %. Razlika v simetriji spodnjih udov, ki je večja kot 10 % in dinamični valgus kolenskega sklepa, sta dva izmed dejavnikov tveganja za poškodbo kolenskega sklepa. Namen: Namen magistrskega dela je prikaz razširjenosti simetrije spodnjih udov in dinamičnega valgusa kolenskega sklepa pri preiskovankah. Metode dela: V raziskavo je bilo vključenih 100 rokometašic, ki v zadnjih 6 mesecih niso imele poškodbe kolena ali gležnja. Simetrija spodnjih udov je bila ocenjena s testi skokov. Test počepa na eni nogi in test skoka s klopi sta bila uporabljena za oceno dinamičnega valgusa kolenskega sklepa. Rezultati: Povprečna starost preiskovank je bila 20,2 ? 4,0 let, povprečna višina 170 ? 6,1 cm in indeks telesne mase 23,4 ± 2,9. 42 % preiskovank je že utrpelo poškodbo kolena ali gležnja. Povprečne vrednosti indeksa simetrije spodnjih udov štirih vključenih testov skokov so bile med 99 % in 102 %. Razlika v simetriji spodnjih udov, ki je večja od 10 % je bila prisotna pri 46 % preiskovank pri vsaj enem izmed štirih vključenih testov skokov. Dinamični valgus kolenskega sklepa večji od 10°, je bil pri 90 % preiskovank prisoten v levem kolenu in pri 86 % preiskovanka v desnem kolenu. Dinamični valgus kolenskega sklepa večji od 10°, je bil pri testu skoka s klopi prisoten pri 31 % preiskovank v levem kolenu in pri 30 % v desnem kolenu. Razprava in zaključek: Ugotovili smo, da je razlika v simetriji spodnjih udov pri skoraj polovici preiskovank večja od 10 % vsaj pri enem izmed štirih testov skokov. Pri več kot 80 % preiskovank je dinamični valgus kolenskega sklepa pri počepu na eni nogi presegal 10°. Razširjenost stanja simetrije spodnjih udov in dinamičnega valgusa v kolenskem sklepu pripomore k ozaveščanju preiskovank in trenerjev o prisotnosti dejavnikov tveganja. Ugotovitve so osnova za vzpostavitev preventivnih programov za izboljšanje kontrole gibanja kolenskega sklepa in simetrije spodnjih udov pri preiskovankah.

• Naslov: Lower limb symmetry using hop tests and assessment of dynamic knee valgus among female handball players : master thesis

Izvleček

Introduction: Based on current evidence, the difference in symmetry of lower limbs should not be greater than 10 %. The difference that is greater than 10 % and dynamic knee valgus, are two of the risk factors for sustaining knee injury. Purpose: The purpose of this master thesis was to display prevalence the lower limb symmetry and dynamic knee valgus in female handball players .Methods: The study included 100 female handball players, who have not had any knee or ankle injuries in the last six months. Hop tests were used to assess lower limb symmetry. Single leg squat test and Drop jump screening test were used to measure dynamic knee valgus. Results: The average age of the handball players was 20,2 ± 4,0 years, the average height was 170 ± 6,1 cm, and the body mass index 23,4 ± 2,9. 42 % of handball players have previously suffered from a knee or ankle injury. 22 % of the handball players had undergone knee surgery. The average value of the lower limb symmetry index of the four included hop tests was between 99 % and 102 %. The difference in lower limb symmetry was greater than 10 % in 46 % of the handball players in at least one hop test. Dynamic knee valgus measured by Single leg squat test was greater than 10° in 80 % of the handball players in the left knee, and 86 % in the right knee. Dynamic knee valgus measured by Drop jump screening test was greater than 10° in 31 % of the handball players in the left knee, and 30 % in the right knee. Discussion and conclusion: In the study we found that almost half of the participating handball players had a difference in lower limb symmetry greater than 10 % in at least one of four hop test. In more than 80 % of the handball players the dynamic valgus measured by One leg squat test was greater than 10°. The display of lower limb symmetry and dynamic knee valgus contributes towards raising awareness about the presence of the risk factors. The findings of this study are a foundation for a possible preventive program for improving knee control and symmetry of the lower limbs in handball players.
