[Comparison of kinesthesia in patients with anterior cruciate ligament tears before and after reconstructive surgery at acute phase]

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

[Effect of reconstruction surgery on hamstring reflex in patients with anterior cruciate ligament tear in acute phase]

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
