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
This study was performed to compare the effects of open and closed chain terminal knee extension exercises on onset latency of vastus medialis obliques [VMO] and vastus lateralis [VL], pain and function in subjects diagnosed with patellofemoral pain syndrome [PFPS]. In a pretest and posttest 5-week intervention study, 26 subjects diagnosed with PFPS and 13 healthy subjects were studied. Subjects diagnosed with PFPS were divided into two groups. One group [n=13] participated in a 5-week rehabilitation program consisted of open chain terminal knee extension exercise and the other group's program [n=13] consisted closed chain terminal knee extension exercise. Electromyographic onsets of VMO and VL collected during step up and step down tasks performed during the pretest and posttest. A Visual analog scale [VAS] and Lysholm questionnaire were administered at pretest and posttest. Analysis of variance was used to compare the three groups. T-test and paired t-test were also used for statistical analysis. VMO and VL onsets timing in PFPS groups were significantly more than those in the control group at the base line [P<0.05]. VMO and VL onset timing differences [VL electromyographic onset minus VMO electromyographic onset] significantly decreased and VAS and Lysholm scores significantly improved for subjects diagnosed with PFPS after intervention [P<0.05]. There was no significant difference between the outcomes of two intervention programs in patients with PFPS. Subjects diagnosed with PFPS responded favorably and quickly to therapeutic exercises program that incorporated open and closed chain exercises
