Background and Objectives: Knee valgus during dynamic activities can lead to anterior cruciate ligament (ACL) tear. The perpuse of this study was to investigate range of motion and isometric strength of ankle joint between gilrs who exhibit medial knee displacement during squat in compraed to control group.Methods: This cross-sectional and descriptive study was carried out on forty healthy females (control, 20 ; dynamic knee valgus, 20) with no lower-extremity injury in the past 6 months elected randomly according to inclusion criteria. Peak isometric strength was measured in kilogeram using a hand-held dynamometer and active range of motion was measured in degrees with a goniometer. Independent t- test and Multi-variate analyses of variance were used to determine differences in strength and range of motion between groups (P≤0.05).Results: The reasults showed dynamic valgus group had the less dorsiflexion range of motion (P=0.000), increased eversion range of motion (P=0.024) and less plantarflexion strength (P=0.000) in compraed to control group.Conclusion: According to present results interventions focusing on improving strength and range of motion of the ankle may improve kinematics during dynamic activities.

Background: The aim of this research was to study the effects of eight weeks aquatic gymnastics Training on the Intensity of Low Back Pain in primiparous women. Materials and Methods: This cohort study was carried out sampling primiparous women (n=62, age range: 28-35 year) in the second trimester of pregnancy were Purposefully selected and divided into two control (n=30) and experimental (n=32) groups. The experimental group performed a 8 week aquatic gymnastics Training both in water and land in the presence of the researcher, with the collaboration of aquatic gymnastics experts and under the supervision of a medical specialist at specialty hospital of Sarem (Tehran-Iran). The Qubeck low back pain standard questionnaire and Burg exercise intensity measurement scale were utilized to compare the results between the pre-/ post-test. The paired t-test and Covariance were used for analysis by SPSS V.19. Results :The results revealed that a 8 week aquatic gymnastics Training significantly relieved the low back pain and promoted the general health of the primiparous women during the second trimester of pregnancy (P=0.001). The back pain intensity was increased in control group (P=0/023). Conclusion: Based on findings of the present study, as aquatic gymnastics Training can eliminate the low back pain and promote the general health among the pregnants, it can be suggested as a non-aggressive method
