Abstract
Background and Aim: According to clinical observation, foot hyperpronation is very prevalent and may cause malalignment of the lower extremity in which can lead to structural and functional deficits in standing and walking. The aim of this study was to investigate of foot hyperpronation effect on spine alignment in standing position.
Material and Method: Thirty-five healthy male ranging 18 - 30 years old were participated in this study. Evaluation was performed with two examiner in four standing positions (on the floor, on the wedges angled at 10, 15 and 20 degrees) using motion analysis system (zebris) and each one of measurement methods repeated three times. SPSS version 17.0 and paired t- test and repeated measures were used for statistical analysis.
Results: Significant difference was seen between all modes in sacral angle, pelvic inclination, lumbar lordosis and thoracic kyphosis variables (except between the first and second mode. Finally, with increasing wedge angle, a positive correlation obtained for the examiners and all variables.
Conclusions: The results of this study showed with increasing bilateral foot pronation, sacral angle, pelvic inclination, lumbar lordosis and thoracic kyphosis were increased. In fact, each one of them considered a compensatory phenomenon.

Abstract
Background and Aim: One of the most common complaints of gait disorders in children is intoeing gait. The aim of this study was to investigate the immediate effect of gait plate insole on gait angle of intoed children.
Materials and Methods: Angle of gait was measured in 17 children aged 4 to 10 years with intoeing gait in 3 modalities: barefoot, ordinary shoes and gait plate insole with ordinary shoes for 3 times consecutively with Rs scan pressure platform.
Results: Gait plate insole with ordinary shoes as well as ordinary shoes alone caused a significant increase (p<0.05) in angle of gait in intoed children. As gait plate insole with ordinary shoes and ordinary shoes increase angle of gait 11.16 and 3.85 degrees respectively versus barefoot.
Conclusion: Use of gait plate insole in association with ordinary shoes can improve gait appearance in children with intoeing gait.

Abstract
Background and Aim: Researches had shown that the high levels of shear and compression stresses that appear in the articular cartilage after meniscectomy are partly responsible for cartilage pathologies, such as osteoarthrosis . In this study, we probe to determine the stress distribution of the medial and lateral meniscus and to choose the appropriate region of meniscectomy.
Materials and Methods: Biomechanical 3D finite element model of the knee joint was generated from CT-scan images. Mimics modeled the bony structure of knee and Solidworks developed the medial and lateral meniscus.
Results: Under an axial femoral compressive load, the maximal contact stress in the articular cartilage after meniscectomy was about twice that of a healthy joint. The maximal contact pressures took place in the posterior region of the medial meniscus, with average values of 1.622 MPa and in the anterior horn of the lateral menisci with 1.159 MPa.
Results: Critical regions determine the allowed region of menisectomy for surgeon. Not only stress distribution doesn`t change by increasing of body weight or meniscectomy, but also the rate of stress increase after meniscectomy.
