Anterior Cruciate Ligament (ACL) injury is one of the most common sport injuries. During sport activities, the status of the various joints of the body, the neuromuscular control pattern and the muscular function can affect stresses on the ACL and its injury rates. The aim of this paper is to study the biomechanical risk factors of noncontact ACL injuries.One of the most important risk factors for ACL injuries are biomechanical factors. Position of the knee joint and torque around it and other body segments such as hip and ankle joints during sport activities can affect the amount of forces on the ACL. Simultaneous to higher incidence of ACL injuries in women, factors that maybe more deleterious for ACL are more evident in women than in men. So it seem, using methods such as neuromuscular training that modify these factors, could help to reduce stresses on ACL and its injury rates, especially in woman.

Depression is a common symptom in patients with Multiple sclerosis (MS). Several reasons contribute to depression in these patients, such as motor disability and inability to perform activities of daily living; while the balance is one of the most important effective factors. So, the aim of this study is to investigate the relationship between balance and depression in patients with multiple sclerosis.
This study was performed using descriptive-analysis, cross-sectional method. People with MS who refer to Isfahan hospitals participate in the study. Convenience sampling was conducted for participants. Based on inclusion and exclusion criteria, only 35 among 95 clients were selected. After recording the demographic information, Beck Depression Inventory and Berg Balance Scale were used to assess depression and balance, respectively. Statistical analysis was performed via SPSS-18 software and Spearman correlation test was used at 5% error level (p The subjects participated in this study consisted of 21 women and 14 men aged 20-60 (32±8.92). The Mean score for Berg Scale was 45.14±10.12 and mean score for Beck Inventory was 17.74±9.65. Statistical analysis of data showed that there is a significant correlation between balance and depression (r= -0.485, p=0.004).
Since the balance and depression problems were seen in the samples of this study, as well as its negative effects on different aspects of life in patients with MS, the existence of balance and depression assessment for comprehensive planning treatment and rehabilitation program seems necessary.
