RESUMO
Anterior cruciate ligament [ACL] tear is one of the most common injuries at knee joint. This study was done to evalute the effect of reconstruction surgery on hamstring reflex in patients with ACL tear. In this Quasi- experimental study, 30 patients [16 males, 14 females] with ACL tear, with mean age of 26.52 +/- 8.72 years old were recruited during 2007. Patients were selected in a non probability sampling manner. The Kinsiological Electromyography and trauma mechanism were used for testing the hamstring reflex. Muscle activity were measured as a dependent variable. Data were analyzed with Paired T-Test, ICC, SEM and K-S tests. Hamstring reflex in affected knee and after reconstruction surgery was 73.25 +/- 3.22 and 47.35 +/- 3.85, respectively. This difference was significant [P<0.05]. Reconstruction surgery in patients with ACL tear at acute phase is effective in improvement of hamstring reflex
RESUMO
Anterior Cruciate Ligament [ACL] tear is one of the most common injuries at knee joint. Threshold of motion sense included inputs that are received by mechanical receptors at dynamic position. The objection of present study was to find the effect of functional brace on the Kinesthesia motion sense in patients with ACL rupture. In this Quasi- experimental study, 20 patients with ACL tear, with aging range between 18 to 44 years old were recruited. Patients were selected in a simple non probability sampling manner. Using Continuous passive motion for testing the Kinesthesia motion sense, as a dependent variable. Data was analyzed with Paired t-test and Colmogrof-Smirnof tests. Threshold of motion sense at affected knee before and after bracing was 3.93 +/- 1.67, 4.45 +/- 1.86 in open eyes and 3.82 +/- 1.61, 4.13 +/- 1.96 in closed eyes [P<0.05]. This study showed that the functional brace did not play in important role in the improvement of threshold of motion sense in patients with ACL tear
