Humans are the only living things which make a erect bipedalism. We are evolving the lower extremity - below a pelvis, and gained the more complicated and more sophisticated gait pattern.In the area of the biomechanics or the rehabilitation, movement analysis instrument has been developed. However, almost of them are attended with the feeling of a constraint, or the measurement place will be limited.We tried to make sensor shoes which can survey operation of the leg without a feeling of a restraint as much as possible.

We followed 38 patients with chronic ankle instability treated by a modified Evans procedure. Evaluation at an average of 68 months follow-up included a standard clinical questionnaire and examination, radiological procedures, and gait analysis. Plantar pressure distribution measurements were recorded during walking and were compared with data from a group of normal subjects (N = 100). The subjective patient questionnaire revealed 87% good or excellent results, but residual pain was reported by 40% of the patients. The gait analysis indicated a significant increase in midfoot loading (22%) consistent with an observed restriction of inversion after surgery. However, the plantar pressure changes were not associated with poor clinical outcome. We cannot say whether these increased pressures will be associated with long-term outcome.

Reconstruction Technique

In this study we modeled a patient specific 3D knee after anterior cruicate ligament (ACL) reconstruction. The purpose of the ACL reconstruction is to achieve stability in the entire range of motion of the knee and the establishment of the normal gait pattern. We present a new reconstruction technique that generates patient-specific 3D knee models from patient?s magnetic resonant images (MRIs). The motion of the ACL reconstruction patients is measured by OptiTrack system with six infrared cameras. Finite element model of bones, cartilage and meniscus is used for determination stress and strain distribution at different body postures during gait analysis. It was observed that the maximum effective von Mises stress distribution up to 8 MPa occurred during 30% of the gait cycle on the meniscus. The biomechanical model of the knee joint during gait analysis can provide insight into the underlying mechanisms of knee function after ACL reconstruction.

Electromyography Signals

Gait is one of the most common and important factor of human movements in daily life. Pelvis is closely connected with the gait due to it allows maintain stable posture by supporting the spine and lower extremities against the gravity. Therefore, pelvic asymmetry, which is caused by biomechanical stress and muscle imbalance, has been associated with postural imbalance and abnormal walking pattern. The purpose of this study was to manufacture customized foot orthotics for improving gait balance and evaluate the effectiveness of customized foot orthotics during walking by measuring lower extremity muscle activity and plantar pressure distribution. All subjects with pelvic asymmetry were asked to walk on a treadmill under three conditions: walking without foot orthotics, walking with customized foot orthotics and walking with non-customized foot orthotics. Root mean square (RMS) value of the electromyography signals, force and peak pressure of the plantar pressure distribution was analyzed based on the gait cycle. The results showed that excessive tension of the muscles and high pressure of the foot that was induced by pelvic asymmetry were more reduced when walking with custom-made foot orthotics than walking without foot orthotics and walking with non-customized foot orthotics. This paper suggest that custom-made orthotics for patients with pelvic asymmetry could be helpful to relieve the excessive loading of the foot and maintain balanced gait pattern.
