Rehabilitation Treatment After Anterior Cruciate Ligament Surgery with Isokinetic and Isotonic Exercises

Generalni cilj ovog istraņivanja je da se uporede uĉinci izokinetiĉkog i izotoniĉkog vjeņbanja na rezultate rehabilitacije pacijenata tri mjeseca nakon hirurńke rekonstrukcije prednjeg ukrńtenog ligamenta. Analiziran je uzorak od 180 ispitanika podijeljen u dva subuzorka u odnosu na vrstu rehabilitacionog tretmana koji je provoĊen. Ispitivanu grupu A-izokinetiĉku saĉinjavalo je 90 muńkih ispitanika, prosjeĉne starosti 28.54±4.44 godina. Kod njih je rehabilitacioni protokol bio zasnovan na izokinetiĉkom vjeņbanju natkoljenih mińića. Ispitivanu grupu B-izotoniĉku (klasiĉnu) saĉinjavalo je 90 muńkih ispitanika, prosjeĉne starosti 27.93±4.27 godina. Kod ovih ispitanika se u rehabilitacionom protokolu za jaĉanje natkoljene muskulature primjenjivao program vjeņbanja sa dodatnim otporom, tj. izotoniĉko vjeņbanje u trenaņnoj sali. Prije poĉetka rehabilitacionog tretmana uraĊen je inicijalni izokinetiĉki test pri ugaonoj brzini od 60°/s kod svih ispitanika. Nakon tri i ńest sedmica rehabilitacionog tretmana raĊeni su kontrolni testovi istim naĉinom i prateći iste parametre kao i na inicijalnom testu. Na osnovu vrijednosti analize MANOVA i analize DISKRIMINATIVNA, naĊeni su znaĉajno bolji rezultati izokinetiĉkih testova u ispitivanoj grupi A - izokinetiĉkoj u odnosu na ispitivanu grupu B - izotoniĉku. Razlika izmeĊu ispitivanih grupa je bila znaĉajnija na finalnom mjerenju nakon ńest sedmica rehabilitacionog tretmana u odnosu na kontrolno mjerenje nakon tri sedmice tetmana. Na osnovu dobijenih rezultata istraņivanja zakljuĉujemo da je izokinetiĉko vjeņbanje djelotvornije po pitanju rehabilitacije natkoljenih mińića nakon rekonstrukcije prednjeg ukrńtenog ligamenta.General aim of this study is to compare the effects of isokinetic and isotonic exercise on the rehabilitation results in patients three months after surgical reconstruction of the anterior cruciate ligament. A sample of 180 subjects was analyzed, divided into two subsamples in relation to the type of rehabilitation treatment that was performed. The examined group A-isokinetic, consisted of 90 male subjects, at the average age of 28.54±4.44. Their rehabilitation protocol was based on isokinetic exercise of the upper leg muscles. The examined group B-isotonic (classical), consisted of 90 male subjects, at average age of 27.93±4.27. In the case of these subjects, an exercise program with additional resistance was applied in the rehabilitation protocol for strengthening the lower leg muscles, i.e. isotonic exercise in the gym. Before the start of the rehabilitation treatment, an initial isokinetic test was performed at an angular velocity of 60°/s in all subjects. After three and six weeks of rehabilitation treatment, control tests were performed in the same way and the same parameters were followed as in the initial test. Based on the values of MANOVA analysis and DISCRIMINATIVE analysis, significantly better results of isokinetic tests were found in the examined group A – isokinetic, compared to the examined group B –isotonic. The difference between the examined groups was more significant at the final measurement after six weeks of rehabilitation treatment compared to the control measurement after three weeks of testing. Based on the results of the research, we conclude that isokinetic exercise is more effective in terms of rehabilitation of the lower leg muscles after the reconstruction of the anterior cruciate ligament
