ABSTRACT
Knee joint is a complex structure and anterior cruciate ligament [ACL] tear is one of the most common injuries of it. Anterior cruciate ligament, because of its proprioceptive function, has an important role in balance control and its tearing may tend to balance control deficiency. The aim of the present study was to evaluate the effect of functional brace on the balance in patients with anterior cruciate ligament rupture. Method: In this quasi-experimental study, 20 patients with anterior cruciate ligament tear, with the age of 18 to 44 years, were recruited. Patients were selected by simple sampling method. Force plate was used for testing the postural balance, as a dependent variable. Data were analyzed using paired-t and chi-square tests. The velocity of center of pressure in x and y directions was not statistically significant comparing the bracing position with bare feet. The difference between pre and post orthotic intervention testing of displacement was not statistically significant in with/without brace position [P>0.05]. According to the results, it seems that the functional brace is not effective in improvement of postural balance in patients with anterior cruciate ligament tear
ABSTRACT
Recognition of kinesthesia impairs after anterior cruciate ligament [ACL] tear and reconstruction surgery can significantly improve the situation. The objective of the present study was to compare the Kinesthesia in patients with ACL tear before and after reconstruction surgery at acute phase. In this Quasi- experimental study, 30 patients with ACL tear were recruited. The patients included 16 males and 14 females selected in a non probability sampling manner. The C.P.M, as a dependent variable, was used to test the Kinesthesia motion sense. Data were analyzed using paired t-test, ICC, SEM, and K-S tests. The kinesthesia in the affected knee and at the speed of 0.5 m/s before and after surgery was 5.02 +/- 0.36 and 3.23 +/- 0.25 and at the speed of 2 m/s 1.95 +/- 0.16 and 0.85 +/- 0.04, respectively. The difference between the pre- and post-surgery was significant at both speeds employed [p<0.05]. It seems that the reconstructive surgery in patients with ACL tears at the acute phase is of high value in improving the kinesthesia

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
ABSTRACT
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
