The purpose of this research was to analyze the effects of the increase of the femoral anteversion angle on the unbalanced quadriceps femoris muscle causing the increase of the valgus force on the knee joints and patellofemoral pain syndrome by comparing with the group that shows the smaller femoral anteversion angle. The method for the research was to compare the femoral muscle's activity while the subjects were maintaining the knee joint flexed isometrically for 10 seconds. The evaluation tool for femoral muscle's activity was QEMG-4 (model LXM 3204). The results were as followings. Firstly, in case of the experimental group, the muscle strength of the vastus lateralis muscle was strong while the rectus femoris and vastus medialis were weak. In these facts, we can see the statistically meaningful difference in vastus medialis muscle activity. Secondly, in the muscle activity analysis for vastus lateralis and medialis of the two groups, we could see the vastus lateralis muscle was strong in anteversion wider for experimental group while the vastus medialis muscle contracted far more stronger in anteversion smaller for control group. From these results, we can see the significant differences in muscle recruitment between the two groups. Above results show that if the anteversion becomes wider, vastus medialis muscle will become seriously weaker, on the other hand, vastus lateralis act stronger.

The main purposes of this study were to find the correlation between walking ability assessment tools using the Modified Barthel Index (MBI), Functional Independence Measure (FIM), Spinal Cord Injury Measurement II (SCIM II), Walking Index for Spinal Cord Injury (WISCI), walking velocity, and walking endurance. The study population consisted of 56 patients with spinal cord injury referred to the department of Rehabilitative Medicine in the National Rehabilitation Hospital. All subjects were ambulatory with or without an assistive device. All participants were assessed by MBI, FIM, SCIM II, WISCI, walking velocity, and walking endurance. The data were analyzed using Pearson correlation analysis and X2. There was significant correlation between the MBI, FIM, SCIM II, WISCI, walking velocity, and walking endurance (p<.01). In particular, WISCI has a significant correlation with SCIM II(p<.001). Therefore the WISCI scale is an appropriate assessment tool to predict the gait ability of patients with spinal cord injury. Further study about MBI, FIM, SCIM II, WISCI, walking velocity, and walking endurance is needed using a longitudinal study design.
