Introduction: The core muscles of trunk are activated before movements of upper and lower limbs. Current evidence suggests that lose of stability in core region predisposes to second injury and appropriate exercise may reduce the risk of reinjury. This aim of this study was to evaluate the effect of eight weeks core stability exercises on dynamic balance, function and strength in athletes after anterior cruciate ligament reconstruction. Methods: This study was a randomized clinical trial. 26 athletes with a history of anterior cruciate ligament reconstruction were purposefully selected and randomly divided into experimental and control groups. The experimental group performed core stability exercises for eight weeks and the control group performed their daily exercises. Dynamic balance, isometric strength and function were meaured using Y balance test, hand held dynamometer and hop tests. Data were analyzed using SPSS vrsion16 software. Independent t-test was used to compare demographic characteristics and Mixed Repeated Measures ANOVA was used to compare the means of the two groups (p≤.05). Results: The results of the present study showed significant improvement in dynamic balance (F=143.92, P=0.000), single-leg hop (F=68.25, P=0.000), triple hop (F=14.02, P= 0.001), knee flexor strength (F=50.21, P=0.000) and knee extensor strength (F=54.72, P=0.000) in the experimental group after eight weeks of core stability exercises. Conclusion: Based on the results of present study, it is suggested to the specialists and trainers involed in the rehabilitation of athletes to use comprehensive and useful core stabilization exercises in the rehabilitation stages of knee injuries.

Background: The optimisation of this return to athletic activity pass by a better understanding of the behaviour of the muscle involved in knee function.In this study, we focused on the muscular activity of the muscle involved in the flexion of the knee. Preciseley on the relation between the muscular activity of the gastrocnemius and the hamstring among the patient that underwent an anterior cruciate ligament reconstruction with hamstring graft.Objective : The objective of the study is to compare, the muscular activity of the flexor knee muscle in patient that underwent an anterior cruciate ligament reconstruction with hamstring autograft and the individuals that have not undergone surgery.Methods : The participants have been divided into two groups : an healthy group and an experimental group that underwent an anterior cruciate ligament recontruction with hamstring graft. The participants had to performe a strenght test on a isocinetik dynamometer. The activity of the medial gastrocnemius, lateral gastrocnemius, femoral biceps and the semitendinosus were mesured during this test.The muscular activity of the muscle mentioned of the individuals in the first group were compared to the ones in the second group via a statistical analysis. Then, a ratio of the activity of the gastrocnemius muscle on the activity of the hamstring was calculated The results of the experimental group were then compared to the results of the control groupResults : The results showed a significative difference activity of the medial gastrocnemius, the femoral biceps and the semitendinosus muscles : the experimental group results were superior to the control group results However the evaluation of the activity reporting has shown significant differences in the two groupsConclusion : This study has allowed us to show a difference in muscular activity of the gastrocnemius and hamstring muscle between patient that underwent an anterior cruciate ligament reconstruction surgery and the heathy participants. However our approch has not allowed us to identify the relation between a heihtened gastrocnemius activity and a diminished hamstring activity following an anterior cruciate ligament reconstruction with hamstring graft. Quite on the contrary, we observed a higher activity of the two muscle groups. Nevertheless, it seem to be necessary to have a variation in situations during the analysis of the gastrocnemius muscle to fully understans its purpose in the functional activity of the knee of patient that have undergone an anterior cruciate ligament reconstruction.

<p><strong>The Purpose</strong> was to improve the treatment outcomes of patients who undergo ACL reconstruction under arthroscopic control through a comprehensive approach to their rehabilitation program.<strong> </strong></p><p><strong>Materials and methods. </strong>We have implemented a system of comprehensive rehabilitation of patients after the ACL reconstruction under arthroscopic control, which relied on the phase of the clinical course of the postoperative period.</p><p><strong>Results. </strong>The study involved 40 patients who underwent anterior cruciate ligament reconstruction under arthroscopic control. Experimental group (20 people) who applied a comprehensive approach in rehabilitation after ACL reconstruction, taking into account the phase of the clinical course of the postoperative period. The second group was the control group (20 patients) in which rehabilitation was carried out under the existing program. The use of cryotherapy with adjustable pulse compression in patients of the experimental group from the first day allowed to reduce twice the use of non-narcotic analgesics. Analyzing the dynamics of flexion in the knee joint, it was found that patients of the experimental group on the 25th day performed flexion by 88.46% of the appropriate maximum. Whereas in the control group just - 69.23%. Positive dynamics were noted in the indicators of myotonometry of the quadriceps muscle and measurement of the perimeter of the knee joint.</p><strong>Conclusions.</strong> The program of physical rehabilitation of patients after the anterior cruciate ligament reconstruction under arthroscopic control, which was built taking into account the phase of the clinical course of the postoperative period, has been developed and offered positive results in clinical practice. The effectiveness of the program was shown by the improvement of such indicators as: decrease in intensity of pain syndrome in the early postoperative period, increase in the range of motion in the knee joint, faster restoration of the tone of the quadriceps muscle of the thighs of patients of the experimental group as opposed to the control group
